I have a database with a couple of tables. One table called spares has foreign keys in another called equipment. When I create a new record, it is added to the spares table however the list action does not show all the columns in the table. It only shows those columns that are not foreign keys. I am using the default action generated by scaffold for list. Why is that so? Do i need to re-write my

Hey everybody, Rails currently offers ''belongs_to :counter_cache'', which is a very basic replacement for count triggers: ":counter_cache - caches the number of belonging objects on the associate class through use of increment_counter and decrement_counter. The counter cache is incremented when an object of this class is created and decremented when it?s destroyed. This requires that a column named "#{table_name}_count" (such as comments_count for a belonging Comment class) is used on the associate class (such as...

Hi everyone, Does anybody know who is responsible for updating *_count columns (via :counter_cache) when creating the db and loading fixtures? In my case, the *_count elements remain zero!

Before I file a ticket, I''ll query ya''ll about this: The API docs for acts_as_tree''s counter_cache is to create a database column called "children_count" to hold the counter_cache. I have enabled this option in my model. While writing tests I wrote a test for creating children from the a parent: message = @forum_message["parent"].find child = message.children.create( "member_id" => 1, "forum_id" => 1...

Is there a way with ActiveRecord to get ahold of a collection containing each association? I want to write a rake task that will dump a model and all its related models to yaml.

My code executes fully: <% for column in ModelName.content_columns %> <th><%= column.human_name %></th> <% end %> but it does not pick up any columns in my model''s table that end in "_id". Is this by design? Is there a helper method that will reference the related tables? Or will I need to code the column titles and detail records by

Hi there, the acts_as_tree API says that I can set a counter cache and that it will automatically increment the "children_count" column. I did that but when I create a new page it asks for a "pages_count" column instead. Here is the relevant part of page.rb model: class Page < ActiveRecord::Base acts_as_tree :order => :position, :counter_cache => true acts_as_list :scope => :parent_id end A...

I?m following along a few tutorials on the web and trying to implement my own example, but I must be missing something because I can?t get has_many or belongs_to to work like I expected. now I have watched all the videos and made a cookbook several times with different interfaces. what I''m looking for is *not* a code snippet to solve something (because I already have that),
