Custom ActiveRecord Error Message

rubyonrails-talk
1

I'm generating 3 models on 1 controller and i'm rescuing ActiveRecord::RecordInvalid for validation errors, however 2 of the models have the same attribute called "name", and if there's an error on that field, I wouldn't know whether that belongs to model A or model B.

What then is the best way of modifying the error message of a validation error without having to rely on locales which I think ActiveRecord encourages you to do.

Currently, my solution is overriding the RecordInvalid#initialize (adding "model class: #{record.class}" to the :errors hash value), but I dont think this is a clean solution.

module ActiveRecord   class RecordInvalid     def initialize(record)       @record = record       errors = @record.errors.full_messages.join(         I18n.t('support.array.words_connector', :default => ', ')       )       super(I18n.t('activerecord.errors.messages.record_invalid',             :errors => "model class: #{record.class}: #{errors}"))     end   end end

What are you doing in the rescue block? Why can't you do something like this:

rescue ActiveRecord::RecordInvalid => e   puts e.record.class end

You're right. How come I didn't think of that. Thanks for the tip :smiley:
