similar to: migration column options not in schema.rb?

Hello. I''m working the "proper way" with creating the initial db schema via migrations and db/schema.rb. However, I have a bit of a special need, and need to know if anyone knows the solution to this; I need a sequence that is common to several tables - a "data id" that gives a sort of unique object number to every row in every table. Some associated tables (a

The recent refactoring didn't work properly for new smart pools, so I've cleaned jup the parameter handling for the various pool 'create' actions.

Hi Railers, I''ve got a Categories table. I want it to act as a list within the scope of the parent_id AND the site_id. Categories table : id label site_id parent_id So, in my Category class, I have : acts_as_list :scope => ''site_id = #{site_id} AND parent_id = # {parent_id}'' The problem is that when I try to move_up a Category with a parent_id that is null,

howdy! I had the problem that attachment_fu didn''t make a thumbnail, but everything else worked. I read this post http://www.ruby-forum.com/topic/104213 and added a parent_id column. now I get the following error when I trie to add a photo: undefined method `find_or_initialize_by_thumbnail_and_parent_id'' for Photo:Class my code is: class Photo < ActiveRecord::Base

I''m using file_column for upload images. now,I want to use the plugin attachment_fu. I have seen that for use it, i must create the attributes like: class CreateMugshots < ActiveRecord::Migration def self.up create_table :mugshots do |t| t.column :parent_id, :integer t.column :content_type, :string t.column :filename, :string t.column :thumbnail,

Don't assume every disk <Item> has a <Parent> field. For floppy disks this is not the case.

I just switched from using the standard "id" column into using my own primary key and generating my own unique id for each record. But, this breaks acts_as_tree. Because my new primary key is not an integer, it breaks the SQL query as follows: StatementInvalid in PagesController#create --------------------------------------------------------------------------------------

Here''s a request string which has a value I want to pull out from the category array - parent_id. Parameters: {"category"=>{"name"=>"Condiments", "parent_id"=>"1"}, "commit"=>"Create"} How do I reference that subelement in the receiving script? I''ve tried params[:parent_id]

I need an ordered (sortable tree) and I just was thinking if somehting like this is possible: class Item< ActiveRecord::Base acts_as_tree :order => "position" acts_as_list :scope => ''parent_id = #{self.id}'' end For my understanding mixing of two acts_as should be p?ssible, at least in this case, right? Unfortunatly the :scope is not working, I am not

I''ve got an acts_as_tree structure which I want to be able to represent in the URL, with one field identified as the url component. In other words, if I''ve got this: def self.up create_table :nodes do |t| t.column :parent_id, :integer t.column :tag, :string end end and class Node < ActiveRecord::Base acts_as_tree end and what I want the urls to be is something

Hi, I''m using the latest gem version of rails under MacOS Tiger. I was trying to use acts_as_tree as described in the rails book. So I have something like: class Category < ActiveRecord::Base acts_as_tree :order => "title" end create table categories ( id int not null auto_increment, title

I am working on an Rails application that uses a pretty complex category structure through out the site. I have defined a table to house all the info and a FK to reference parents within the table CREATE TABLE categories ( id int(11) NOT NULL auto_increment, name varchar(50) NOT NULL, parent_id int(11) default NULL, constraint fk_category_id foreign key (category_id) references

I am trying to create a record with association. Within the create method, I would also like to pre-populate dependent (has_many) records from a template in the database. The child records are <u>mysteriously rolled back </u> if I insert them in a loop. If I try to insert a single child record, it works.I have read the books and tried to google my way out of this but am at a dead

Hello, I am just starting off with Rails, so I apologize in advance if there is a terribly obvious answer to my problem. I''ve done some searching and found similar problems to my own, but nothing which yielded a solution. I have a handful of models that I am unit testing. The tests for each unit run successfully, but when I do a rake test, many of the tests fail. The assertions that

Hello everybody I have a model with better_nested_set.

Guys, I''m having a problem getting acts_as_tree working. It seems from the Agile book (p. 255) that acts_as_tree only supports one-to-one record relations, whereas I need many-to-many support. In other words, looking at the picture at the top of page 256 where where only 1 id is linked to 1 parent_id, I need multiple id''s linked to multiple parent_id''s - for
