similar to: Validation that works in the controller

ActiveRecord supports composed_of for value objects which is fantastic but one thing that it doesn''t seem to support (or at least I am unable to find any documentation for) validation of the value objects. For example, given the following: class Message < ActiveRecord::Base composed_of :sender, :class_name => ''EmailAddress'' composed_of :recipient,

Hey All, I have a form that submits data to multiple models. I have class Man < ActiveRecord::Base has_many :notes has_many :contacts validates_associated :contacts, :notes validates_presence_of :first_name validates_presence_of :last_name class Contact < ActiveRecord::Base belongs_to :man validates_presence_of :contact_info class Note < ActiveRecord::Base

I have a problem with ruby on rails validation total_book_toy.rhtml ================ <%= text_field ''book1'', ''title1'' %> <%= text_field ''book2'', ''title2'' %> I want to validate these text_field so user can''t insert same title. However, I was stuck how to do it. Or maybe you have another way how to do it.

If I have belongs_to :user Do I need to have validates_presence_of :user_id ? Does Rails validate the presence of :user_id automatically if I have belongs_to :user? In other words, does Rails prevent against creating orphan records that belong to non-existent users? Thanks. -- Posted via http://www.ruby-forum.com/.

Hi, I am not sure if this is already answered in this list. I couldn''t find an answer. So I am posting the question. I have multiple validations for a field. For example: validates_presence_of :contact_email validates_format_of :contact_email, :with => /^([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})$/i, :message => "is not a valid email

Regarding validates_associated... Let''s say I have: article belongs_to author But for whatever reason, I want an article to also be written anonymously and therefore not require an author. Then I have: Article: belongs_to :author validates_associated :author But I DON''T have validates_presence_of. What I want to do is validate that an author is valid --if it is

I have two problems. I have a comment that has_many uploads. Before saving the comment, I want to be sure that the upload(s) has passed validation, but I also need to validate in other ways. For example, I do not want to save the comment if there is no comment or upload. Or, I do not want to save the comment if the image has been uploaded previously (comparing md5s with past upload md5s

I have a model that contains a :boolean field. In my view, I have a simple select of Yes or No, which equates to true or false, respectively. If I choose yes and save, everything works great. If I choose no, my model fails validation as I have this set as a required field using validates_presence_of. I have checked the log and it''s definitely set to false, why would this fail validation?

Hello, Hope this isn''t a newbie question - but I don''t seem to be able to find relevent information elsewhere.

Hello all. I''ve got the following in my model: class Individual < ActiveRecord::Base validates_presence_of :first_name, :last_name, :street, :city, :state, :zip validates_acceptance_of :AZ_resident, :message => "You must be an Arizona resident." end The AZ_resident field is present and defined as boolean (PostgreSQL 8.1), but validation will not occur.

I am having problems with a validation, the full model code is below. The validate routine is attempting to see if another record with the same artist_name, title, & catalogue_no exists in the products table. If so, it should throw an error. This is the validation code: def validate if Product.find(:all, :conditions => ["artist_name = ?, title = ?, catalogue_no = ?",

Hi list, is it possible to check if form field will be required when form is submitted (through validates_presence_of or some other validates_* method)? I could do this manually but it doesn''t seems to me very DRY. For example, I would like to be able to dynamically add asterisk with some helper method if city is required here: City*: <%= text_field

Hey people, I was wondering how to solve the following problem... I have a login system which uses MD5 + salts to store my users passwords in the database. Also I am working with profiles for my users which they can change. Everything goes quite okay except when we reach the change_profile bit of the application. Because the user model has validations it performs on the password it starts

Anyone got any idea of how to use built-in validation methods in a mixed-in module. What I''ve got at the moment is each class that needs ranking methods includes [the module] Ranking. Then the module Ranking has a bunch of instance methods and a submodule ClassMethods. The ClassMethods in this are mixed in to the class with self.included. So far so good. But I want the module to

Hi, I am trying to restrict duplicate has_and_belongs_to_many associations. I tried to find support for a association validation for duplicates but couldn''t find anything. I understand I could use :uniq=>true on the model association but this would only prevent it from displaying duplicates, I want to stop duplicate associations being inserted in the first place. I have a vague
