Hopefully someone can help me on this one, it's absolutely driving me crazy!
Basically, I have created an Authentication system on my app, using Devise and CanCan, which works fine. The problem arises when I try to assign a Role to a User on signup, the Users Role does not save, the sign-up is successful, but the User has no assigned Role. In my Console the Users Role comes up as nil!
I've set up a HABTM association between Users and Roles, and tried various options. Rails Console returns User Role:nil even if I input the role as a String in the sign-up form.
I am new to Rails and programming in general, would really appreciate some assistance people! Many Thanks in
User Model:
class User < ActiveRecord::Base
has_and_belongs_to_many :roles
# Include default devise modules. Others available are:
# :token_authenticatable, :encryptable, :confirmable, :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
# Setup accessible (or protected) attributes for your model
attr_accessible :email, :username, :password, :password_confirmation, :remember_me, :role_ids
def role?(role)
return !!self.roles.find_by_name(role.to_s.camelize)
end
end
Snippet from New Registration View:
<fieldset>
<legend>Sign Up</legend>
<div class="inputs">
<%= f.input :username, :required => true, :autofocus => true %>
<%= f.input :email, :required => false, :autofocus => true %>
<%= f.i开发者_运维技巧nput :password %>
<%= f.input :password_confirmation, :label => "Confirm Password" %>
</div>
<div>
<%= f.input :roles, :required => true, :collection => Role.find(:all).collect {|c| [ c.name, c.id ]}, :label => "Role" %>
</div>

After many investigations, this question raised another question but no real here.
