similar to: why do i not get error warning from validation?

I have tweaked my schema to The Rails Way and have generated a bit of scaffolding. I am trying to create a new Part, which references a PartName and a PartNumber. I can create a PartNumber on the fly, but the PartName has to exist. I have an inelegant solution

I am trying to understand why model validation error reporting in Rails is so complicated compared to non ajax model validation. In my normal form I use <%= error_messages_for ''user'' %> in my view and I get a nice error message displayed when the user inputs invalid information into the form. When I convert that form to use Ajax using form_remote_tag the

I have the following setup: A model: that validates using helpers like: validates_presence_of, etc..

I seem to be missing something trying to use ''validates_inclusion_of'' to validate a foreign key and was hoping some one could piont out my mistake? The problem seems to be that Order.find_all.collect is not returning an array that contains the order_id, if I replace it with a hardcoded array everything works as expected. The model: class OrderItem < ActiveRecord::Base

Hi I''ve got a problem validating a boolean and I can''t see what the problem is.

Hi all, I am a newbie to Rails. Please enlighten me on how to do this appropriately, the Rails and the Ruby way: Suppose I have a Recipe model.

It appears that if your trying to use validates_inclusion_of for a string value allow_nil wont work. For example, if I have an attribute :year which is stored as a varchar then: validates_inclusion_of :year, :in => "1980"..Time.now.year.to_s, allow_nil=>true will successfully validate the range but will not allow an empty input field to be submitted. However, if :year is

Hello, I''m having trouble with after_validation_on_create causing my validations to fail silently. I''ve got a restful_authentication based user model that requires a number of things from the user: email, dob, gender, etc. When a user is created, all of these are validated in various ways (presence, inclusion_of, etc.). Afterwards, I call three protected methods using
