Hi all I have a model Member that has a habtm relationship to buddies (also members). Now I wanted to sort them using sort, but this ends in an error "undefined method <=>"!

Hi Team! Just having a bit of trouble with the many-to-many relationship of the same type. Im trying to build a buddy list. So I have a users table and want to allow each user to have a buddlist of users. Ive tried having a User model and a Buddy model where the buddy model has 2 fields user_id and a buddy_id but i cant get the buddy.name methods to resolve when getting a list of buddies.

Hello list, I think I''ve found a bug in the way Rails is talking to my Postgres DB when recording HABTM data. My join_table looks like this: id serial primary key, tablea_id integer references tablea(id), tableb_id integer references tableb(id), other_attributes... When Rails writes to join_table, I''d expect it to do something like: INSERT INTO join_table (tablea_id,

I''m having a problem with belongs_to and has_and_belongs_to_many. Here''s a brief summary of the models involved: class Member < ActiveRecord::Base set_primary_key ''member_id'' has_and_belongs_to_many :projects, :join_table => ''projects__members'' has_many :projects, :foreign_key => ''created_by'' end class

Hi, I am trying to perform a query with ActiveRecord that I want to put into a Rails application later. For now I just wrote it within a plain old Ruby script for easier testing. I am working with an existing database so I had to map some foreign keys myself. As you can see from the models below, the database has a structure of Prospectlists <=habtm=> Contacts <=habtm=> Accounts

I need to have a table related to itself via a join table. Will HABTM support this? That is: class Recipe < ActiveRecord::Base has_and_belongs_to_many :recipes, :join_table => "recipes_recipes" end More importantly -- how does RoR support MULTIPLE self-joins? I.e., to relate the table to itself via multiple join tables. SFAIK, HABTM won''t support multiple

Imagine I want to track people, and the clubs that they belong to. table people with columns person_id, person_name table clubs with columns club_id, club_name And I have the association table: table clubs_people with columns person_id, club_id Now I know how to do this habtm between the two, in order to associate people with clubs that they belong to. However my application also needs a

Hi, Posting here since issue tracking isn''t the best place to discuss. I can understand habtm is moving towards deprecating support for extra attributes in join_table, and to use :through for those cases instead. To clarify, patch<http://dev.rubyonrails.org/attachment/ticket/5216/habtm_join_table_test.patch1.diff>for #5216 <http://dev.rubyonrails.org/ticket/5216>

Here''s a simplistic model class. class Person < ActiveRecord::Base has_and_belongs_to_many :relatives, :class_name => ''Person'', :join_table => ''relatives'', :foreign_key => ''from_id'', :association_foreign_key => ''to_id'' has_and_belongs_to_many :brothers, :class_name =>

Hi all I have the following models: class Member < ActiveRecord::Base # DJ Profiles the member is part of has_and_belongs_to_many :disc_jockeys, :join_table => ''members_are_disc_jockeys'', :uniq => true end class DiscJockey < ActiveRecord::Base # Members that are part of this DJ profile

Cheers, I have a problem with 1.0 and a habtm relationship between User and Article. I want to save all articles that users read.

Hi, I''m having a little trouble figuring out how to make a self- referential HABTM bi-directional. I have a Employee class. Each employee can have a couple of bosses, who are also employees. The employee class has the following HABTM: has_and_belongs_to_many :bosses, :class_name => "Employee", :join_table => "bosses_courses", :association_foreign_key =>

Hi all, I''m working with a legacy sqlserver db and I''m trying to override the insert sql in as defined in the HABTM method below(becasue the join has three primary keys), but I''m getting the error: ''undefined local variable or method `record'' for Project:Class'' has_and_belongs_to_many :people, :class => ''Person'',

Hi all I have the following models: class member has_and_belongs_to_many :disc_jockeys end class disc_jockey has_and_belongs_to_many :members end The relation table is called disc_jockeys_members and has the following fields: disc_jockeys_members(disc_jockey_id, member_id, status) So far, the field status can have values like valid, invalid, locked etc., but it is not regarded yet by

as i''ve read somewhere. this could be fixed easily. all the rails devs ( or whoever is responsible for the query building and executing part) have to do is to use the full qualifier in the sql statements (e. g. DB_Name.Tablename.Row). to solve that problem in the meanwhile one should define the :join_table in the habtm association with the full qualifier. -- Posted via

Hello! I have 2 table: users and buddies User: id, name, ... Buddy: id, user_id, user_buddy_id, ...

And there is conflict if I had the second one (the first one is discarded) class User has_many

Briefly, I want to create an :insert_sql attribute for a has_and_belongs_to_many relationship, and then add items to that relationship using push_with_attributes. Is that possible? Less briefly: I have a legacy postgresql database where one of the join tables has an ID column, so I had to set up the association with a custom :finder_sql attribute, as follows: class Topic <

Pardon my newbness. I''m trying to create, populate, and save an object with an HABTM mapping. That''s not working too well so far ;) Assuming I have the mapping correct (HA!) and the db set up properly, how do I create the select and options? I guess mostly I want to know what I''m supposed to name it. I have a FilingEvent class - HABTM State (both models have the
