Devise before_filter authenticate_admin?

Question

I added an admin role to Devise by adding a admin attribute.

Could you tell me if this is the right way to create a before_filter that requires an admin user to be signe

Answer 1

Go with this approach

  before_filter :authenticate_user!
  before_filter do 
    redirect_to new_user_session_path unless current_user && current_user.admin?
  end

This also ensures any guests are forced to sign in as well. You don't need to modify the default method to force authentication just to access the instance method admin?

def admin?
  self.admin == true
end

My approach is to create a role attribute and check its string value against a set of intended roles - it's far more flexible this way rather than having to create many boolean attributes.
