How to unit test a Symfony2 form when it uses a transformer linked to a database

TLDR: I am new to unit tests and I have few questions:

Are my transformer tests well written?
Is there a way to decoupled my transformer tests from the database?
How to test my form with the transformer using the database?
Should I decouple my form from my transformer?

I don't know if my classes are too coupled, if my design is flawed or if my understanding of the unit tests is bad.

Here is some background. I have a form object with different widgets. One of them is used within a model transformer. This model transformer uses a connection to the database to retrieve the proper object.

Here is my code:

class BookToStringTransformer implements DataTransformerInterface {
    private $om;
 
    public function __construct(ObjectManager $om) {
        $this->om = $om;
    }
 
    public function transform($book) {
        if (!$book instanceof Book) {
            return "";
        }
 
        return $book->getName();
    }
 
    public function reverseTransform($string) {
        if (!is_string($string) || !$string) {
            return null;
        }
 
        $book = $this->om
                ->getRepository('MyBundle:Book')
                ->findOneBy(array('name' => $string))
        ;
 
        if (null === $book) {
            throw new TransformationFailedException(sprintf(
                    'The book "%s" does not exist!', $string
            ));
        }
 
        return $book;
    }
}
 
class ItemType extends AbstractType {
    private $om;
 
    public function __construct(ObjectManager $om) {
        $this->om = $om;
    }
 
    public function buildForm(FormBuilderInterface $builder, array $options) {
        $bookTransformer = new BookToStringTransformer($this->om);
        $builder->add($builder->create('book', 'text', array(
                    'required' => false,
                ))->addModelTransformer($bookTransformer));
    }
 
    public function setDefaultOptions(OptionsResolverInterface $resolver) {
        $resolver->setDefaults(array(
            'data_class' => 'MyBundle\Entity\Item',
        ));
    }
 
    public function getName() {
        return 'mybundle_item';
    }
}

I wrote unit tests for the transformer using the KernelTestCase

class BookToStringTransformerTest extends KernelTestCase {
    private $name = 'existing name';
    private $em;
 
    public function setUp() {
        static::$kernel = static::createKernel();
        static::$kernel->boot();
        $this->em = static::$kernel->getContainer()
                ->get('doctrine')
                ->getManager();
    }
 
    public function testReverseTransform_whenNameExists_returnsBookObject() {
        $transformer = new BookToStringTransformer($this->em);
        $book = $transformer->reverseTransform($this->name);
        $this->assertInstanceOf('MyBundle\Entity\Book', $book, 'Should return a Book object');
        $this->assertEquals($this->name, $book->getName(), 'Should return a Book object with the selected name');
    }
 
    /**
     * @expectedException Symfony\Component\Form\Exception\TransformationFailedException
     */
    public function testReverseTransform_whenNameDoesNotExist_throwsException() {
        $transformer = new BookToStringTransformer($this->em);
        $transformer->reverseTransform('unknown name');
    }
 
    /**
     * @param mixed $invalid_parameter
     * @dataProvider provideInvalidParameter
     */
    public function testReverseTransform_whenParameterIsInvalid_returnsNull($invalid_parameter) {
        $om = $this->getMockBuilder('Doctrine\Common\Persistence\ObjectManager')->getMock();
        $transformer = new BookToStringTransformer($om);
        $this->assertNull($transformer->reverseTransform($invalid_parameter), 'Should return a NULL value');
    }
 
    /**
     * @return array
     */
    public function provideInvalidParameter() {
        return [
            [null],
            [false],
            [true],
            [''],
            [[]],
            [new \stdClass()],
        ];
    }
 
    public function testTransform_whenParameterIsBookObject_returnsName() {
        $book = $this->em->getRepository('MyBundle:Book')
                ->findOneBy(array('name' => $this->name));
        $om = $this->getMockBuilder('Doctrine\Common\Persistence\ObjectManager')->getMock();
        $transformer = new BookToStringTransformer($om);
        $this->assertEquals($this->name, $transformer->transform($book), 'Should return a string containing the name');
    }
 
    /**
     * @param mixed $not_book
     * @dataProvider provideInvalidBookObject
     */
    public function testTransform_whenParameterIsNotBookObject_returnsEmptyString($not_book) {
        $om = $this->getMockBuilder('Doctrine\Common\Persistence\ObjectManager')->getMock();
        $transformer = new BookToStringTransformer($om);
        $this->assertEquals("", $transformer->transform($not_book), 'Should return an empty string to be chained');
    }
 
    /**
     * @return array
     */
    public function provideInvalidBookObject() {
        return [
            [null],
            [123],
            ['123'],
            [[]],
            [true],
            [new \stdClass()],
        ];
    }
}

As I am new to unit tests, I don't even know if it is the proper way to test that transformer. I start writing tests for the form object. I am using the TypeTestCase but there is no simple way to get the connection to the database and I can't use the KernelTestCase.

class ItemTypeTest extends TypeTestCase {
    /**
     * @expectedException \PHPUnit_Framework_Error
     */
    public function test_whenCreatedWithNoParameters_raiseException() {
        new ItemType();
    }
 
    /**
     * @expectedException \PHPUnit_Framework_Error
     */
    public function test_whenCreatedWithBadParameters_raiseException() {
        new ItemType(123);
    }
 
    public function test_whenCreatedWithGoodParameters_createsFormObject() {
        $om = $this->getMockBuilder('Doctrine\Common\Persistence\ObjectManager')->getMock();
        $type = new ItemType($om);
        $form = $this->factory->create($type);
        $this->assertInstanceOf('Symfony\Component\Form\Form', $form);
    }
 
    public function test_whenSubmittedWithGoodData() {
        $formData = array(
            'name' => 'existing name',
        );
 
        $om = $this->getMockBuilder('Doctrine\Common\Persistence\ObjectManager')->getMock();
        $type = new ItemType($om);
        $form = $this->factory->create($type);
 
        $form->submit($formData);
    }
}

The last test fails because the transformer does get access to the database since I am passing a mock to the form. So should I get a real object (meaning classes are too coupled) or should I find an other way.

Thank you

The approach is good, in the last method you must mock the repo object and the repo response. In example try this code:

public function test_whenSubmittedWithGoodData() {
    $formData = array(
        'name' => 'existing name',
    );
 
    $om = $this->getMockBuilder('Doctrine\Common\Persistence\ObjectManager')->getMock();
 
    $repoMock= $this->getMock('Doctrine\ORM\EntityRepository', array(), array(), '', false);
 
    $om
        ->expects($this->atLeastOnce())
        ->method('getRepository')
        ->withAnyParameters()
        ->will($this->returnValue($repoMock));
 
 
    $repoMock
        ->expects($this->atLeastOnce())
        ->method('findOneBy')
        ->withAnyParameters()
        ->will($this->returnValue($mockedBook));
 
    $type = new ItemType($om);
    $form = $this->factory->create($type);
 
    $form->submit($formData);
}

Is there a better way to handle the Doctrine proxy object

I have two classes linked with a one-to-one relation.

class Client {
    ...
    /**
     * @ORM\OneToOne(targetEntity="ClientInfo")
     * @ORM\JoinColumn(name="id", referencedColumnName="client_id")
     */
    private $info;
    ...
    public function doSomething() {
        if (!$this->getInfo() instanceof ClientInfo) {
            return false;
        }
        return $this->getInfo()->doSomething();
    }
    ...
}
 
class ClientInfo {
    ...
    /**
     * @ORM\Id
     * @ORM\OneToOne(targetEntity="Client")
     * @ORM\JoinColumn(name="client_id", referencedColumnName="id")
     */
    private $client;
    ...
    public function doSomething() {
        return 'something';
    }
    ...
}

Those classes are loaded with database content with Doctrine. It is working perfectly when there is data in the database. But if there is not ClientInfo data, I have a \Doctrine\ORM\EntityNotFoundException raised.

So I changed the doSomething() method to take this into account.

    public function doSomething() {
        if (!$this->getInfo() instanceof ClientInfo) {
            return false;
        }
        try {
            return $this->getInfo()->doSomething();
        } catch (\Doctrine\ORM\EntityNotFoundException $e) {
            return false;
        }
    }

But it does not feel right to me since it is tied with Doctrine. I am trying to modify my unit tests to add a mock of the proxy object but it does not feel right either.

Is there a better way of doing that?

EDIT 1

I followed Nico Kaag suggestion but it does not change anything.

My constructor in my Client class look like this:

public function __construct() {
    $this->info = new ClientInfo();
}

If I do a var_dump of $this→info after retrieving my object with Doctrine, this is what I get.

object(Proxies\__CG__\MyBundle\Entity\ClientInfo)[444]
  public '__initializer__' => 
    object(Closure)[461]
  public '__cloner__' => 
    object(Closure)[462]
  public '__isInitialized__' => boolean false
  private 'client' (MyBundle\Entity\ClientInfo) => string '21055' (length=5)
  ...

EDIT 2

I finally changed what I have done. I removed the try..catch block and change the query to retrieve objects from database. Now I force the query to retrieve the ClientInfo object at the same time as the Client object.

This way, I can trust my test and if I forget to query both objects simultaneously, I will have an exception to remind it to me.

See I have made classes for you.

use Doctrine\ORM\Mapping AS ORM;
 
/**
 * @ORM\Entity
 */
class client
{
    /**
     * @ORM\Id
     * @ORM\Column(type="integer")
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;
 
    /**
     * @ORM\OneToOne(targetEntity="Entities\client_info", inversedBy="client")
     * @ORM\JoinColumn(name="client_info_id", referencedColumnName="id", unique=true)
     */
    private $clientInfo;
}

use Doctrine\ORM\Mapping AS ORM;
 
/**
 * @ORM\Entity
 */
class client_info
{
    /**
     * @ORM\Id
     * @ORM\Column(type="integer")
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;
 
    /**
     * @ORM\OneToOne(targetEntity="Entities\client", mappedBy="clientInfo")
     */
    private $client;
}

Try this, you will not get such issue.

Also I have used bi-directional relation with cardinality one-to-one, parent connection 0:1*- (parent optional), please see the diagram.

Suggetion : Use ORM designer tool for designing and extracting entity classes.

How to test a concrete method calling an abstract method with phpunit

I have an abstract class with concrete method. So I want to test those concrete methods.

Here is my abstract class:

abstract class File {
    private $debug_filename_pattern = 'DELETE_ME_%s.debug';
    private $filename;
    private $filepath;
 
    abstract public function buildFilename();
 
    public function __construct($debug = false) {
        $filename = $this->buildFilename();
        if ($debug) {
            $filename = sprintf($this->debug_filename_pattern, $filename);
        }
        $this->filename = $filename;
        $this->buildFilepath();
    }
 
    private function buildFilepath() {
        $this->filepath = ini_get('upload_tmp_dir') . DIRECTORY_SEPARATOR . $this->filename;
    }
}

I read the section on testing abstract classes in phpunit documentation and I came up with that test:

final class FileTest extends \PHPUnit_Framework_TestCase {
    public function test() {
        $stub = $this->getMockForAbstractClass('MyBundle\File', [true]);
        $stub->expects($this->atLeastOnce())
                ->method('buildFilename')
                ->withAnyParameters()
                ->will($this->returnValue('test.log'));
        $this->assertEquals('C:\xampp\tmp\DELETE_ME_test.log.debug', $stub->getFilePath());
    }
}

But it is not working. My assert always returns that it fails with this error message:

Failed asserting that two strings are equal.
--- Expected
+++ Actual
@@ @@
-'C:\xampp\tmp\DELETE_ME_test.log.debug'
+'C:\xampp\tmp\DELETE_ME_.debug'

I understand that my mock object is instantiated and then I add a mock for buildFilename method. Making my test always fail.

Is there a way to mock my abstract method before instantiation? Should I refactor my abstract class instead?

I don't think that you are able to set up your mock the way that you want. The construct method is being called when you →getMock(). Then you are trying to set expectations after the fact.

Generally, I find that when something becomes difficult to test as in this case it is a sign that there is an issue with the design. I think that the issue you have is that you are doing too much in your constructor in this case.

You are doing all sorts of heavy lifting to determine the filepath on the construct of your object. Why not change it so that it happens when you call getFilePath. Your class would end up looking like this:

abstract class File {
    private $debug_filename_pattern = 'DELETE_ME_%s.debug';
    private $filename;
    private $filepath;
    protected $debug;
 
    abstract public function buildFilename();
 
    public function __construct($debug = false) {
        $this->debug = $debug;
    }
 
    private function buildFilepath() {
        $filename = $this->buildFilename();
        if ($this->debug) {
            $filename = sprintf($this->debug_filename_pattern, $filename);
        }
        $this->filename = $filename;
        $this->filepath = ini_get('upload_tmp_dir') . DIRECTORY_SEPARATOR . $this->filename;
    }
 
    public function getFilePath() {
        if(!this->filepath) {
            $this->buildFilepath();
        }
 
        return $this->filepath;
    }
}

Now in your test to make sure that the path gets built only once just add your assertion one more time.

final class FileTest extends \PHPUnit_Framework_TestCase {
    public function test() {
        $stub = $this->getMockForAbstractClass('MyBundle\File', [true]);
        $stub->expects($this->once())
                ->method('buildFilename')
                ->withAnyParameters()
                ->will($this->returnValue('test.log'));
        $this->assertEquals('C:\xampp\tmp\DELETE_ME_test.log.debug', $stub->getFilePath());
        $this->assertEquals('C:\xampp\tmp\DELETE_ME_test.log.debug', $stub->getFilePath());
    }
}

How to revert a chunk of a file in the staging area?

I have a file in my staging area and I want to unstage a chunk of it. I know I can use the following command:

git reset --patch -- <my_file>

But in my case, the name file was renamed and every time I am trying to validate the reset, I have the following error:

fatal: new file my_file depends on old contents

Is there a way to do what I need? Or I am screwed?

Edit:

I read the following documentation before posting this question:

Edit:

Git status output:

Changes to be committed:
  (use "git reset HEAD <file>..." to unstage)

        renamed:    src/MyBundle/Config.php -> src/MyBundle/QueryConfig/Config.php

In the rename process, I want to keep some changes (namespace change) but I want to discard other changes (not related to namespace change) to commit them later.

So finally I found a process that works for me:

I move the file back to its original location
I revert the chunks I don't want to include in the commit
I move the file to its final location

So here are the commands :

git mv <final_path>/<file> <original_path>/<file>
git reset -p <original_path>/<file>
git mv <original_path>/<file> <final_path>/<file>

@MatzZze Even if I did not use your solution, I thank you for your help. It is greatly appreciated.

To unstage chunks use:

git reset HEAD -p <filename>

After that you can reset your changes with

git checkout -p <path to file>

How to handle a POST method that generate multiple resource with REST?

I am building my first REST API. I could do most of my queries without any problem but now I encountered a use case I don't know how to solve.

Here is the use case. I submit a dataset to the API, the dataset is then stored in database (this part works as intended). When stored in the database, it creates different resources due to business rules. So now I don't know how to inform the user what is the location of the newly created resource since I could have more than one.

I read this Can the Location header be used for multiple resource locations in a 201 Created response? which tells me that only one location header is allowed. Should I rethink my POST method? Should I use a different way to acknowledge the user where are the resources?

Yes, the Location header requires a single identifier. It's intended for one resource you should follow in order to complete the request according to some predefined semantics.

You can use the Link header instead. Then you can have multiple URIs. Check the RFC 5988 here for a few examples and don't forget to document it properly.

As an alternative, keep in mind that the semantics of the POST method are determined by you, so there's nothing wrong with returning the list of links in the response payload, as long as the resource format allows it in some way and it's documented.

Symfony form validation of integer field

I am trying to use the type validation rule with integer and it fails with some warning.

Here is my form

class BusinessType extends AbstractType {
    public function buildForm(FormBuilderInterface $builder, array $options) {
        $builder->add('business_number', 'integer', array(
            'required' => false,
        ));
    }
}

Here is my validation rule

My\Bundle\Entity\Business:
    properties:
        business_number:
            - Type:
                type: integer

So nothing extravagant!

But I get the following error

Uncaught PHP Exception Symfony\Component\Debug\Exception\ContextErrorException: “Warning: NumberFormatter::parse(): Number parsing failed”

I already found a work around here, but it doesn't feel right to do that. I will if there is no other solution but I prefer to avoid it.

I know it was a known bug in earlier version of Symfony but it is supposed to be fix. See here.

So is there a way I can use the type validation? And if so, what am I missing?

Edit 1

I am using Symfony 2.6.6

Edit 2

If my value starts with numbers (like 123dd), I have the following error message, even if I customized my error message

This value is not valid.

But if my value starts with something else, I have the error fore-mentioned.

Edit 3

The longest value I need to store is 9 digits long. So integer should work properly.

Edit 4

Here is the bug report

The problem is that the integer and/or number Symfony Form Type utilizes the Symfony\Component\Intl\NumberFormatter\NumberFormatter::parse method before storing the value to the Form. The contents of the method are as such (as of Symfony 2.6.6):

public function parse($value, $type = self::TYPE_DOUBLE, &$position = 0)
{
    if ($type == self::TYPE_DEFAULT || $type == self::TYPE_CURRENCY) {
        trigger_error(__METHOD__.'(): Unsupported format type '.$type, \E_USER_WARNING);
        return false;
    }
    preg_match('/^([^0-9\-\.]{0,})(.*)/', $value, $matches);
    // Any string before the numeric value causes error in the parsing
    if (isset($matches[1]) && !empty($matches[1])) {
        IntlGlobals::setError(IntlGlobals::U_PARSE_ERROR, 'Number parsing failed');
        $this->errorCode = IntlGlobals::getErrorCode();
        $this->errorMessage = IntlGlobals::getErrorMessage();
        $position = 0;
        return false;
    }
    preg_match('/^[0-9\-\.\,]*/', $value, $matches);
    $value = preg_replace('/[^0-9\.\-]/', '', $matches[0]);
    $value = $this->convertValueDataType($value, $type);
    $position = strlen($matches[0]);
    // behave like the intl extension
    $this->resetError();
    return $value;
}

Notably this part:

preg_match('/^([^0-9\-\.]{0,})(.*)/', $value, $matches);
// Any string before the numeric value causes error in the parsing
if (isset($matches[1]) && !empty($matches[1])) {
    IntlGlobals::setError(IntlGlobals::U_PARSE_ERROR, 'Number parsing failed');
 
// ...

will cause any malformed entry with a string at the start to throw an Exception.

Unfortunately, changing the validation rules will do nothing as this parsing is run before validation occurs.

Your only workaround will be the one you've linked, and to submit a bug report until the problem is fixed. The current master branch doesn't have an update to this file and it's unclear if the problem was solved elsewhere (further research would be required).

Front-end validation could also help (for example, the built-in validation for HTML5 number and integer types will cause most browsers to stop you before submitting to Symfony).

Symfony2 - Collection type is displayed twice in my view

I have a form with a collection and I can see it properly when I use the following syntax:

form_row(form.items)

Then when I try to render it by myself, it is duplicated.

Here is my code in my twig file:

{{ form_errors(form) }}
{{ form_start(form) }}
 
    ... some fields here ...
 
    <div id="{{ form.items.vars.id }}" class="collection items" data-prototype="{{ form_widget(form.items.vars.prototype)|e }}">
        <h3>{{ form_label(form.items) }}</h3>
        <a href="#" class="add_link">Add</a>
        {% for item in form.items %}
            {{ form_row(item) }}
        {% endfor %}
    </div>
 
    ... some other fields here ...
 
{{ form_end(form) }}

Here is my code in my form object:

    $builder->add('items', 'collection', array(
        'type' => new ItemType(),
        'allow_add' => true,
        'allow_delete' => true,
        'by_reference' => false,
        'required' => true,
    ));

Add here is my output:

<!-- This is the one I need, I removed the prototype for the sake of clarity -->
<div id="bundle_data_items" class="collection items" data-prototype="...">
    <h3>
        <label class="required">Items</label>
    </h3>
    <a href="#" class="add_link">Add</a>
</div>
<!-- This one is automatically added. The prototype is empty -->
<div>
    <label class="required">Items</label>
    <div id="bundle_data_items" data-prototype=""></div>
</div>

Do you have any ideas why this happens?

I followed that documentation. Did I miss something?

Edit:

This happens only when my collection is empty

I found the solution to that.

It turns out that when the collection is empty, the rendering of it never occurs. I could use sjagr solution but as there is some fields I want to render automatically, I cannot use it.

So my solution is the following:

{{ form_errors(form) }}
{{ form_start(form) }}
 
    ... some fields here ...
 
    <div id="{{ form.items.vars.id }}" class="collection items" data-prototype="{{ form_widget(form.items.vars.prototype)|e }}">
        <h3>{{ form_label(form.items) }}</h3>
        <a href="#" class="add_link">Add</a>
        {% for item in form.items %}
            {{ form_row(item) }}
        {% else %}
            {% do form.items.setRendered %}
        {% endfor %}
    </div>
 
    ... some other fields here ...
 
{{ form_end(form) }}

When your collection is empty, the for loop in {% for item in form.items %} never gets to execute, hence form_row(item) never happens. This means, to Twig/Symfony, you never actually outputted the field.

Then you do form_end at the end of the form. This is not usually a big deal, but from the docs:

This helper also outputs form_rest() unless you set render_rest to false

So, you must simply pass a false value for render_rest:

{{ form_end(form, {'render_rest': false}) }}

I'm not sure how form_widget did fix your problem, but I'm also not sure how you tried that alternative - perhaps you ran it outside of the for loop.

As an aside, you should consider making your own form.html.twig template file so you can reuse the markup format you've chosen for your collection. It will allow you to simply do form_widget(…) without having to break apart the pieces and your form_end will always consider the field to be outputted even if the collection is empty.

Unfortunately i cannot comment yet (no 50 rep), but perhaps this is caused the browser itself. A rendering issue due to markup someplace? See if the raw http response has the same thing. Since it works with form_row(form.items) but not your own, it “could be” that.

I would check if it's empty also before outputting it.

How to choose the driver to serialize/deserialize with jmsserializer

I have an object which I serialize using annotations. It works fine.

If I am using yaml configuration, it works fine also.

My problem is I want to use both in different context. Lets say that in controller one, I want to use the annotation configuration and in controller two, I want to use the yaml configuration. I want to do that because I need to have different field names in those outputs.

I tried to override the serializer with a new instance using only the annotation.
I change jmsserializer service configuration to not use specific drivers. It worked but I cannot choose which one to activate dynamically.
I tried to select the driver in the container but I couldn't make it work.

Is this possible? Am I missing something?

I don't see how you can achieve this.

But if you to want expose a property differently, you can create different views of your object by using an exclusion strategy.

Example :

/**
 * @JMS\ExclusionPolicy("all")
 * @ORM\Entity
 */
class FooBar
{    
    /**
     * @ORM\Column(type="string")
     * @JMS\Groups({"foo"})
     */
    protected $name; // output 'name'
 
    /**
     * @ORM\Column(type="string")
     * @JMS\SerializedName("foo_bar_name")
     * @JMS\Accessor(getter="getName", setter="setName")
     * @JMS\Groups({"bar"})
     */
    protected $fooName; // output 'foo_bar_name'
 
    // ...
 
    public function setName($name)
    {
        $this->address = $name;
 
        return $this;
    }
 
    public function getName()
    {
        return $this->name;
    }
}

Like this, the property can be serialised in two different names :

use JMS\Serializer\SerializationContext;
 
$serializer->serialize(new FooBar(), 'json', SerializationContext::create()->setGroups(array('foo')));
 
//will output $name as 'name'
 
$serializer->serialize(new FooBar(), 'json', SerializationContext::create()->setGroups(array('bar')));
 
//will output $fooName as 'foo_bar_name'

Note the @JMS\SerializedName is not mandatory, you can use it for custom names.

See more at the Exclusion strategies part of the documentation.

Hope this could be an alternative for you.

Talend warning and error messages are black

When I was using Talend on Windows, I could see warning and error messages. Now that I am using Talend on Linux, all I can see is black rectangles.

Do I need to embedded or install missing java libraries? If so, how do I find those missing?

Here are what I am using:

Ubuntu 17-04
Talend Open Studio for Big Data
Openjdk 1.8.0_131

Edit Here is a capture of the black rectangle when I hover the warning sign on one of my table.

This seems to be connected to your desktop engine (KDE / Gnome) and Eclipse.

See the answers from this question https://askubuntu.com/questions/45001/how-to-fix-black-tooltips-in-eclipse to check out how you can resolve the issue.

How to use a variable as user name in a SF memory provider?

I was trying to use a variable provided by my .env file as the username in the memory provider in my security.yml file. My configuration looks like that:

security:
    providers:
        page:
            memory:
                users:
                    "%env(PAGE_USERNAME)%": { password: '%env(PAGE_PASSWORD)%' }

It was working recently but now I've got an exception every time I am using the console. Here is the exception:

[Symfony\Component\DependencyInjection\Exception\EnvParameterException]                                                                
A service name ("security.user.provider.concrete.page_%env(PAGE_USERNAME)%") cannot contain dynamic values.

After some research, it turns out that there was a modification in Symfony\Component\DependencyInjection\Compiler\CheckDefinitionValidityPass recently which changed that behavior.

Is there another way of doing what I want to do? Is this considered as a bug?

List available workflows in Symfony

I am using symfony workflow component in a symfony 3 project. I would like to list all available workflows.

Is there a way to find that list? I was looking in the component code base but didn't find anything I could start working on.

Just make a debug with search term.

debug:container --show-private workflow

this would be the result:

Select one of the following services to display its information:
  [0] console.command.workflow_dump
  [1] workflow.abstract
  [2] workflow.marking_store.multiple_state
  [3] workflow.marking_store.single_state
  [4] workflow.registry
  [5] workflow.security.expression_language
  [6] workflow.blog_publishing
  [7] workflow.blog_publishing.definition
  [8] workflow.twig_extension
  [9] Symfony\Component\Workflow\Registry

The above is a simple and a not usable result for your bussiness logic.

If your intention is to do “something” with the output, take a look at the Symfony\Bundle\FrameworkBundle\Command\ContainerDebugCommand and try to extend the command and implement your own logic.

If you extend(which I recommend) the Command you will have access to the getContainerBuilder function which gets you the builder container and then you can do $builder→getServiceIds() and start a string search inside a loop returning all the matched services and that would be your workflow list.

Hope it helps!

How to define a macro to interpret a unicode character with Mathjax

I have the following markup in my page:

<p>$$\textbf{P} = \left⌊ \frac{\left( \left⌊ \frac{\textbf{A}}{100}\right⌋  \times 8 + 13 \right)}{25}\right⌋  - 5$$</p>

When MathJax tries to render it, I have the following error:

Missing or unrecognized delimiter for \left

I figured that the left floor (⌊) and right floor (⌋) unicode characters are what is not recognized in my expression because when I replace them with \lfloor and \rfloor, it's working properly.

My MathJax configuration is the following:

window.MathJax = {
  tex: {
    inlineMath: [['$', '$'], ['\\(', '\\)']],
    displayMath: [['$$', '$$']]
  }
};

I've tried to add macros to interpret the unicode characters with the following configuration with no luck:

window.MathJax = {
  tex: {
    inlineMath: [['$', '$'], ['\\(', '\\)']],
    displayMath: [['$$', '$$']],
    macros: {
      "⌊": '{\\lfloor}',
      "⌋": '{\\rfloor}'
    }
  }
};

Knowing that I can't change the markup because I not the one maintaining it and I have no way of changing it, is there a configuration that will allows me to make it work.
