Symfony2 translating validator messages

After some digging and searching, I found the way that suit me best for translating messages from validation config file. I like to use yml format so let me show how I did it:

#Surgeworks\CoreBundle\Resources\config\validation.yml
#...
Surgeworks\CoreBundle\Entity\User:
    properties:
        firstName:
            - NotBlank: { message: "not.blank.first_name" }
        lastName:
            - NotBlank: { message: "not.blank.last_name" }
        email:
            - NotBlank:  { message: "not.blank.email" }
            - Email: { message: "Please provide valid E-mail address" }
        username:
            - NotBlank:  { message: "not.blank.username" }
            - MinLength: {limit: 6, message: "min.length.username"}
        password:
NotBlank:  { message: "not.blank.password" }
#...

Next procedure is same as for regular messages:

Inside messages.{_locale}.yml

#Surgeworks\CoreBundle\Resources\translations\messages.en.yml
#...
not:
  blank:
    first_name: First name can not be blank!
    last_name: last name can not be blank!
    email: E-mail can not be blank!
    username: Username field can not be blank!
    password: Password field can not be blank!
#...

And use it inside controller:

        //...
 
        $user = new User();
        $user->setFirstName($first_name);
        $user->setLastName($last_name);
        $user->setEmail($email);
        $user->setUsername($username);
 
        //...
 
        $errorList = $this->get('validator')->validate($user);
        $msg = "";
        if (count($errorList) > 0) {
            foreach ($errorList as $err) {
 
                $msg.= $this->get('translator')->trans($err->getMessage()) . "\n";
            }
            return $msg; //translated error message using your translations
        }
 
        $this->getEm()->persist($user);
        $this->getEm()->flush();
 
//...

Enjoy with your Symfony2! 🙂
