There is a model relation like this.
class A
belongs_to :ref_config,:class_name => 'User'
end
My question is : the A has a attribute named flag, now i want to create a function like this:
if flag == 1, I want the class A like this belongs_to :ref_config,:class_name => 'Department and if flag == 2, i want the class A like this belongs_to :ref_config,:class_name => 'User'
How can I implement the function
Thank you!
