Question

Symfony version: 3.1.3 Database: MySQL

I have the users table and it has a column as roles(LongText-DC2Type:array).

In my controller I have

Answer 1

Here is what I did to get rid the issue,

Define Roles in the /app/config/security.yml as below,

role_hierarchy:
    ROLE_ADMIN:         [ROLE_ADMIN]
    ROLE_SUPER_ADMIN:   [ROLE_SUPER_ADMIN, ROLE_ALLOWED_TO_SWITCH]
    ROLE_TEACHER:       [ROLE_TEACHER]
    ROLE_STUDENT:       [ROLE_STUDENT]
    ROLE_PARENT:        [ROLE_PARENT]

in the Controller, get the roles from the /app/config/security.yml using the following code

$roles = $this->getParameter('security.role_hierarchy.roles');

and this is the code to roles in the formtype,

$roles = $this->getParent('security.role_hierarchy.roles');

and then in the formtype, (here it is multi select)

->add('roles', ChoiceType::class, array(
    'attr'  =>  array('class' => 'form-control',
    'style' => 'margin:5px 0;'),
    'choices' => 
    array
    (
        'ROLE_ADMIN' => array
        (
            'Yes' => 'ROLE_ADMIN',
        ),
        'ROLE_TEACHER' => array
        (
            'Yes' => 'ROLE_TEACHER'
        ),
        'ROLE_STUDENT' => array
        (
            'Yes' => 'ROLE_STUDENT'
        ),
        'ROLE_PARENT' => array
        (
            'Yes' => 'ROLE_PARENT'
        ),
    ) 
    ,
    'multiple' => true,
    'required' => true,
    )
)

Edit User roles has to be defined in the /app/config/security.yml as below

role_hierarchy:
    ROLE_ADMIN:         [ROLE_ADMIN]
    ROLE_SUPER_ADMIN:   [ROLE_SUPER_ADMIN, ROLE_ALLOWED_TO_SWITCH]
    ROLE_TEACHER:       [ROLE_TEACHER]
    ROLE_STUDENT:       [ROLE_STUDENT]
    ROLE_PARENT:        [ROLE_PARENT]
