Hello, I''m creating my own Tumblr [tumblr.com] like rails app. It''s like a blog, but in this case a blog post could be of a certain type, i.e. a regular post, a video, a link, a photo, a song(info).

Hi all, I''m having some trouble with a has_many association on a table using the single table inheritance model that I''m hoping someone can help me with. The schema for the table is: CREATE TABLE `comments` ( `id` int(11) NOT NULL auto_increment, `user_id` int(11) default NULL, `type` varchar(20) NOT NULL default '''', `type_id` int(11) NOT NULL default

With a has_one/belongs_to relationship, what''s the best way to guarantee that the belongs_to object gets created and is accessible alongside the has_one object? I *think* the after_create callback is a good choice, but I discovered an oddity while trying it. F''rinstance, if every horse has a carriage: ============ ActiveRecord::Schema.define do create_table(:horses) {|t|

I thought I had this fixed, but apparently not. It works okay from the console, but not from the view. I have the following: # partial schema create_table "users", :force => true do |t| t.string "login", :null => false t.string "first_name" t.string "last_name" t.string "email", :null => false

Hi, I''m having some problem with getting collection_select to return the current value when editing a record.

Anyone have an idea on this? Got a weird situation where on a specific model I can not create an instance using params, yet it works fine on other models. The model which does not work is a stock model, there is no logic in it. Ruby 1.8.7/Rails 3.0.5. Does not work: (rdb:1) PaymentTransaction.create(:purchase_id => 3) #<PaymentTransaction id: 2, purchase_id: nil, action: nil, amount: nil,

Isn''t there a proper way or hack/workaround for the following? * For the example with unfortunate disabilities.. look below,,, Usage of has_* (associationmethods) do {def with_deleted AccociatedModel#with_scope} {Paranoid''s#find_with_deleted}... The has_one associations give me a nil object when invoking it with Model.association_OBJECT.with_deleted. Has_many does like
