alias_method_chain :validates_associated, :informative_error_message
I dislike the vague error message produced by validates_associated.
class User
validates_associated :profile
delegate ..., :to => :profile
end
I see the following error message: profile is invalid. But WHY was the profile invalid? The validation errors from the profile should bubble up to the user. So,
module ActiveRecord::Validations::ClassMethods
def validates_associated(association, options = {})
class_eval do
validates_each(association) do |record, associate_name, value|
associate = record.send(associate_name)
if associate && !associate.valid?
associate.errors.each do |key, value|
record.errors.add(key, value)
end
end
end
end
end
end
Now we see:
Music tastes can't be blank
Eh, voila!
I really like this, but it seems to only work with has_one associations. Here's my adaptation, for better or worse:
def validates_associated(*associations) associations.each do |association| class_eval do validates_each(associations) do |record, associate_name, value| associates = record.send(associate_name) associates = [associates] unless associates.respond_to?('each') associates.each do |associate| if associate && !associate.valid? associate.errors.each do |key, value| record.errors.add(key, value) end end end end end end end

Hi, thanks for the tips.
Excuse me for this probably stupid question but where do I put that piece of code?
Thanks
