The fields_for tag, when working with ActiveResource''s accepts_nested_attributes_for returns the params like this: "book"=>{"name"=>"sdfas", "chapters_attributes"=>{"0"=>{"name"=>"sdfaasdf"}}} Note thé "0" as a key to the "chapters_attributes" hash. When working with ActiveResource it gives me this ''wrong constant name 0'' because it tries to ''find or create'' an resource for each key of the nested attribute hash. Someone knows how to fix it? I''m not supposed to use fields_for with ActiveResource? Thanks. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
