Question

Is there a way to declare attr_accessible for multiple roles without a ton of duplication?

If I have several user roles, and each role is allowed to edit a different subset of attributes, here’s what my attr_accessible declaration looks like:

attr_accessible :first_name, :last_name, :active, :as => :admin
attr_accessible :first_name, :last_name, :as => :manager
attr_accessible :first_name, :last_name, :as => :guest

I’d like to either

• A) define an array of accessible attributes that can be shared among
  different roles or
• B) define an array of roles than can access the same
  attributes

Is this possible?

Answer 1

All ruby code is still just ruby code… and is thus infinitely hackable. eg

ROLES = [:admin, :manager, :support, :user, :guest]
ACTIVE_ROLES = [:admin, :support]
ROLES.each do |role|
   fields = [:first_name, :last_name]
   fields += [:active] if ACTIVE_ROLES.include?(role)
   attr_accessible *fields, :as => role
end
