Hi, Everything is in the title. With Rails 2.3.4 and MySQL 5.0.41: If have a table like this: +----------------+------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +----------------+------------+------+-----+---------+----------------+ | id | int(11) | NO | PRI | NULL |

Hi all I want users to register on my page. To register, they only have to deliver an email and a password. Then a link with an activation token will be sent to them, and after clicking the link the user sees a page where he should fill in further details, means: a username. My model looks like this: class Member < ActiveRecord::Base validates_presence_of :username, :if =>

Context: I have a GoodsReturn model with many ReturnedItem. For the new view, I create a new GoodsReturn with many new ReturnedItems from a sale (and its SoldItems). Problem: I want to have a Add/Selected checkbox with which the user can pick the items he wants to return. I know I could use a ''selected'' virtual attribute but I don''t want to pollute my model just for

Is there a built-in way to determine if a model object has just been created (ie. this object was the one that was originally persisted)? I can''t see it anywhere in the AR code, but thought I''d check. I want something like: p = Person.create p.original_instance? # true Is this built-in or should I just patch AR? -Jonathan.

How do I use the ruby debugger with a specific test (not the whole spec file)? I want to do something like this. $ rdebug spec/models/user_spec.rb -s "should error if not new_record" ____________________________________________________________________________________ Looking for last minute shopping deals?

What I need is

I want to modify and update the items in the Depot - "display_cart". Since the cart is in a session, its a little hard to get at the data. I just want to create a way to change quantities, prices and recalculate. Has someone done this, and could you point me to the right direction. Thanks Chas -- Posted via http://www.ruby-forum.com/.

Does anyone know if Rails is supposed to validate associated objects on creation? Say you have a User model, with has_many posts, and a Post model which belongs_to user. Further, the Post model has a validates_uniqueness_of :title. u = User.find(1) # this should pass u.posts.create :title => ''my new post title'' # this should fail u.posts.create :title => ''my

Hi, I just ran into this ActionController::RoutingError and just wanted to check if someone can confirm this as a bug in the Rails 3 beta gem. config/routes.rb contains: get ''login'' => ''session#new'' post ''login'' => ''session#create'', :as => :login GET /login works fine: Started GET

I''ve been stumped on this for a few days and I''m not sure if it''s an error on my end or an actual bug. I have a system where I have workshops and users. Workshops have students, presenters, and troubleshooters. I wanted to represent this simply by using has_many :through with :source. Workshop has_many :presenters, :through =>:presenterships, :source=>:user

I just can''t get validates_confirmation_of working for the life of me!... It''s not the first time I''m having problems with it but I just never understand why!... This time I pretty much followed *exactly* the example in Agile Rails Development and still...it just won''t work! I put 2 different passwords in the form and it doesn''t trigger an error,

Hello I have this routes.rb Tamara::Application.routes.draw do ActiveAdmin.routes(self) devise_for :admin_users, ActiveAdmin::Devise.config resources :users resources :category do resources :berichten end end So I thought that localhost:3000/<category>/bericht/new I could write a new bericht which is stored in the <categoryname> But when I look at rake routes

As far as I can tell, the counter_cache option on a belongs_to model doesn''t actually save anything in the database. For example, I have the following models: class Parent < ActiveRecord::Base has_many :children, :conditions => "deleted_at IS NULL" end class Child < ActiveRecord::Base belongs_to :parent, :counter_cache => true end With the following

Why can''t I access an associated model in a validate method? I have some code that looks like the following: Models: class Product < ActiveRecord::Base has_many: upcs end class Upc < ActiveRecord::Base belongs_to :product def validate errors.add_on_blank(''upc'') unless product.new_record? end end Controller: def create @product =

I never want to alter a model(row). When a model has been changed i want a new copy to be created. What is the best way to implement this? I think using callbacks might be the answer. So model.save will create a new row, and leave the old one unchanged. Any ideas? I can easily implement this in the controller but i''d rather it be done transparently. Also errors should be passed back

I have two objects, QuoteInput and Insured. QuoteInput has one Insured and Insured belongs to QuoteInput. I don''t understand what I''m seeing. I assign an Insured to a QuoteInput. The Insured object has invalid data. I call save! on the quote input. QuoteInput has no validations. I expect two things to happen - 1) an exception should be thrown, indicating that there was a

Is it possible to get the current Controller''s action from within the Model? I have a situation where I want a piece of validation to run on edits, but not on new creates. Thanks, - Mark -- Posted via http://www.ruby-forum.com/.

Hello all ! I have a model being validated that spits it''s error messages on the resulting page using: error_messages_for(:mymodel) .... Basic stuff. It''s working perfectly. Now, I have something else I want to check on the same page (that isn''t an attribute to the Model)... and am trying to add it using: @mymodel.errors.add_to_base("another error here")

I''m sure I''m not getting something. I have Users, and I have Groups. Each User has_and_belongs_to_many :groups and each Group has_and_belongs_to_many :users. When I add a user, I want to apply a bunch of groups (like tags) to the user (manually, without acts_as_taggable). Here''s User#create: @user = User.new(params[:user]) @user.groups =

Hello List, I''m trying to generate examples for some list-helpers I have coded which use in my projects. Basically, the Playlist class uses one anonymous module in has_many that acts as helper between acts_as_list and my desired API: class Playlist < ActiveRecord::Base # associations go here has_many :playlist_items, :order => :position, :dependent => :destroy has_many
