Has a field through an association

Rails
1

Hey guys,

Trying to figure out how to do something like the following:

class Child
belongs_to :parent
has_field :some_field, :through => :parent
end

class Parent
has_one :child
attr_accessible :some_field
end

child.some_field #=> parent.some_field
child.some_field = value #=> sets parent.some_field = value

I can of course accomplish this by adding custom accessors to Child, but
looking for a better solution. I could also write a plugin that
dynamically adds the accessors, but not sure if something already
exists.

Thanks in advance,
Garrett L.

It sounds like you’re looking for something like delegate_belongs_to:

It does pretty much exactly what you’ve described.
