RAILS: How to get has_many associations of a model

Question

how I can get the has_many associations of a model?

For example if I have this class:

class A < ActiveRecord::Base   has_many B   has_many C end 

I would a method like this:

A.get_has_many 

that return

[B,C] 

Is it possible? Thanks!

Answer 1

You should be using ActiveRecord reflections.

Then you can type something like this:

A.reflect_on_all_associations.map { |assoc| assoc.name} 

which will return your array

[:B, :C] 

Answer 2

For Example you could try :

aux=Array.new Page.reflections.each { |key, value| aux << key if value.instance_of?(ActiveRecord::Reflection::AssociationReflection) }
