ruby on rails 3 - Specify attribute list in attr_accessor with method call -


i want create large number of attributes can done ease if constructed method call this,

 attr_accessor :attr_list    def attr_list    [:x1, :y1, :x2, :y2]     end

this not working. there other way achieve this?

any appreciated.

figured out,

def self.attr_list  [:x1, :y1, :x2, :y2]    end  attr_accessor *attr_list

explanation:

as attr_accessor method call expects parameters list. can not pass array is. (*) convert array parameters list.

just need define class method returning array of attribute list passed attr_accessor.

works attr_accessible(or similar) well.
