Role management

[RignonNoel]

We want to add a new feature allowing administrator to create Role that they can assign to Users, each role will contain a set of permissions that we can use on the Cell we are linked to.

Expected behavior

• Administrators can manage Role (create/update/delete)
• Administrators can link some permissions to a Role
• Administrators can link a User to a Cell with a given Role
• Administrators can remove link between a User and a Cell

Current behavior

Only administrators can manage Cell for the moment and it's a problem since some administrators should not have the right to manage ALL the Cell

Potential solution

Here is a potential UML diagram for the solution:

Here is an example of role model that can be used:

• Package for MultiselectField
• Package that we already use to manage permission inside Volontaria

class Role(models.Model):

    PERMISSION_A = 'permission_a'
    PERMISSION_B = 'permission_b'
    
    PERMISSION_CHOICES = [
        (PERMISSION_A, 'Permission A'),
        (PERMISSION_B, 'Permission B'),
    ]

    name = models.CharField(
        max_length=100,
        blank=False,
        null=False,
        verbose_name=_("Name"),
    )

    permissions = MultiSelectField(
        choices=PERMISSION_CHOICES,
        verbose_name=_('Permissions'),
        blank=True,
        null=True
    )

    def __str__(self):
        return self.name
