Is there a way to list all belongs_to associations?

Question

I need to list all belongs_to associations in a model object and iterate through them. Is there a way to do this?

Answer 1

Thing.reflections.collect{|a, b| b.class_name if b.macro==:belongs_to}.compact 
#=> ["Foo", "Bar"]

of course, you can pass :has_many, or any other associations too
