Model: before_save do doing_some_stuff begin File.open('some_file', 'w+') do |file| if file.write(file_content) return true else return false end end rescue => e self.errors.add(:base, e.message) return false end View: <%= @model.errors.any? %> This is always false. How do I add error messages to the model? EDIT: The problem was, I had a redirect after the update_attribute function instead of rendering the action again.

Like this before_create :do_stuff –Pierre-Louis Gottfrois Jul 1 '13 at 18:34 How do you know that the File.open is raising an exception? Are you sure that its not just returning false from that else statement inside the open block? –Leo Correa Jul 1 '13 at 18:38 i had logged out the error via logger.info to the logfile, the error raises in the rescue part –SonIcco Jul 1 '13 at 18:43 can you log self.errors.inspect in the rescue part as well ? –Pierre-Louis Gottfrois Jul 1 '13 at 18:46 #

For example, if i want to validate that a the time period between :start_date and :end_date doesnt contain any sunday, the error doesnt belong specifically to either of those fields, but the Errors add method requires to specify it. ruby-on-rails share|improve this question asked May 30 '12 at 14:36 agente_secreto 2,784144276 add a comment| 4 Answers 4 active oldest votes up vote 23 down vote accepted Try doing something like this: # Your Model.rb validate :my_own_validation_method ... private def my_own_validation_method if there_is_no_sunday_in_the_range self.errors[:base] << "You must have a Sunday in the time range!" end end Basically, you can add your own complex validations to a model, and when you see that something erroneous has happened, you can add an error string in the array of errors. share|improve this answer edited May 30 '12 at 14:52 answered May 30 '12 at 14:46 MrDanA 8,65221634 1 Perfect, this is just what I needed.

You can also pass additional options to provide a context for an error object: class User < ActiveRecord::Base validate :adulthood def adulthood errors.add(:age, :too_young, years_limit: 18) if age < 18 end end user = User.new(age: 15) user.valid? user.errors.details # => {age: [{error: :too_young, years_limit: 18}]} All built in validators populate details hash by default.
