similar to: Validating Foreign Key

Hello, I have a form that submits data to two related models/tables. One is Customer the other is Address. Validation for Customer works fine but not for the Address. Class Customer < ActiveRecord::Base has_one :address validates_presence_of :login, :password, :email validates_associated :address end Class Address < ActiveRecord::Base belongs_to :customer validates_presence_of

I am trying to set up a validation in a model to ensure that a record can''t be saved unless the foreign key it belongs_to is a valid record. My model says: class Admin < ActiveRecord::Base validates_presence_of :user_id validates_numericality_of :user_id validates_uniqueness_of :user_id validates_associated :user belongs_to :user end but I can still create an admin

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

Hi, I''m struggling to get the validates_associated to work as I think it should be. I''m using: JRuby 1.1 rails-2.0.2 activerecord-2.0.2 activerecord-jdbc-adapter-0.8.2 My tables in MySQL: CREATE TABLE area_codes ( id INT UNSIGNED auto_increment primary key ... ); CREATE TABLE markets ( id INT UNSIGNED auto_increment primary key, ... ); CREATE TABLE

Here is my model: class Account < ActiveRecord::Base has_many :users, :dependent => :destroy has_many :bus belongs_to :currency has_many :mylogs, :dependent => :destroy has_many :batchuserdefines, :dependent => :destroy has_many :materialuserdefines, :dependent => :destroy has_many :materials has_many :inventories has_many :batchs has_many :courses has_many

Hi, I think I''m missing some fundamental information here so hopefully someone can help me. I have a model Club which has many members, members of course belong to a Club.

Hello all I''m having an issue with ruby on rails, and it not throwing an error where it should.

Here is the setup: Windows XP, InstantRails, MySQL 14.7, Ruby 1.8.4, Rails 1.1.2 MODEL: class Office<ActiveRecord::Base has_many :users end class User<ActiveRecord::Base belongs_to :office validates_presence_of :office_id validates_associated :office <....other stuff...> end UNIT_TEST test/unit/user_test.rb def test_associations u = User.new u.office_id =

Thanks for the input Blair Zajac and Chris (Nolan and Hall), and for others. If all of you have time, please follow this (the question still relates to the previous posts by me): I have provided full steps to reproduce the symptoms. If it matters, I''m running Ruby 1.8.2, Rails 1.0, and MySQL 5.0.15 on Windows XP Professional. 1. First, the setup MySQL ----- create database testdb;

Hi all, For various reasons I need to have foreign keys with not null constraints. Eg: create_table :people do |t| t.column :name, :string t.column :household_id, :integer, :null => false end create_table :households do |t| t.column :name, :string end add_foreign_key_constraint :people, :household_id, :households, :id So the people table has a foreign key into

I have a wizard which consists of two pages. To keep it simple let''s say that the first page asks the user to select a state from the drop down menu. In case the user doesn''t select any state, an error message needs to be displayed. Ideally I would like to do something like this. def new selected_value = params[:addevent][:state_id] if selected_value == "-1"

I''m trying to assign a parent foreign key value using collection_select from my child "new" form. The problem I''m having is if I do not make a selection, I get the following error instead of the Rails validates_presence_of error: You have a nil object when you didn''t expect it! You might have expected an instance of Array. The error occurred while evaluating

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

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 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. Let''s simplify things and pretend that it has only 2 attributes, a :name and the other is a ''category_id''. In the recipes table, category_id is a foreign key to field id of table categories. We also assume that I have generate

Hi friends!
