search for: parent_ids

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 --------------------------------------------------------------------------------------

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,

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

Hello everybody I have a model with better_nested_set. In my "new" form, i pass the desired parent_id as a hidden field, and in the create action at the controller i save the new register and use move_to_child_of Model (params[item][parent_id]) Everything works, but at my log file it warns that i can''t mass asign the property "parent_id". What can i do to avoid the

Let''s say I have simple schema with two tables. The models are defined like the folllowing: class Parent < ActiveRecord::Base has_many :children end class Child < ActiveRecord::Base belongs_to :parent end Simple has_many relationship. Is there any way to order the results of a Parent.find_all by the number of children the parent has? I can sort with sorted_parents =

Hi I''m pretty much a newbie to Rails and I have at least two projects under development that are going to need the same type of constructs and I''m struggling to get my head around how to achieve what I want using Rails models and relationships. In one project I have a hierarchy of (geographical) sites. For example: Earth Europe Ireland Cork Kerry Galway

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

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

Hi, has anyone successfully used the acts_as_threaded plugin with postgresql? I''m using rails 1.0 and ruby 1.8.4 on linux. Following the screencast on http://www.railtie.net/articles/2006/02/05/rails-acts_as_threaded-plugin , I got to where we''re ready to create our first post, having made the changes to controllers/posts_controller.rb, views/posts/_form.rhtml,

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

So I have a select list with a list of items. When a user selects an item, another select list should have its default selected item set to a specific item (the default associated with the first select list). This is in a form to create a new task. The first select list is a list of parent tasks. When one selects the parent task, the clients select list must default to the same client as its

I am using ruby 1.8.4 with rails 1.0 under fedora core 3 on a WIntel platform. Rails appears to be losing key information under some circumstances. Specifically, in the Questions class that follows, the presentation_id property is apparently being lost. The STDOUT dump from the create method indicates that the presentation_id should be 42, but the dump from the database shows that it is 43,

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
