I've recently added roles to my rails application with CanCanCan (by enumeration)- but now I want to add a default role on signup. How do I go about doing this? Does it go in the controller or model?
My User model:
class User < ActiveRecord::Base
#Defining different roles
enum role: [:Admin, :User, :Guest]
#Users can only create one scholarship application
has_one :applications
# Include default devise modules. Others available are:
# :confirmable, :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
end
My Ability Model - there's just three roles, an administrator which I will create through seeding the database with a user with a role of 1- and then everyone else should be 2 on signup.:
class Ability
include CanCan::Ability
def initialize(user)
user ||= User.new # guest user (not logged in)
if user.role = 1
can :manage, :all
elsif user.role = 2
can :manage, Application
can :manage, User
else
can :read, Static_Page
end
end
end
回答1:
you can add callback to your model
before_create :set_default_role
private
def set_default_role
self.role ||= Role.find_by_name('your_role')
end
devise article
or in your case you can do
before_create :set_default_role
def set_default_role
self.update_attribute(:role,'your_role')
end
