similar to: Create and join two models in one form (HABTM)

Hi, I''m currently stuck with a problem I just can''t find a clever solution for. I checked every tutorial, issuetracker, API reference I could find but found nothing to "enlighten" me --> I desperately need your help :-). My Question is: is it possible to use nested forms for habtm associations? --> Here some more info about what I wanted to do and what failed

so i am trying to save to a join table in a habtm relationship, but i am having problems. from my view, i pass in a group id with: = link_to "Create New User", new_user_url(:group => 1) User model (user.rb) class User < ActiveRecord::Base has_and_belongs_to_many :user_groups accepts_nested_attributes_for :user_groups end UserGroups model (user_groups.rb) class UserGroup <

Hi, I have a User model with a HABTM relation to a Role model and vice versa. So There''s a roles_users table that references :user and :role. I''m using formtastic, and in the user.edit.html.erb I have a line that outputs the roles as a multi-select list box. But the box is not showing the roles that have been assigned to the users. Another problem is that if I select a few

I''m trying to get a multi level nested form model working but have hit a problem. In one of my models, I have a habtm association and it''s throwing an error on a nested form and these are check boxes with a method of ''time_unit_ids[]''. The nested forms work without the habtm (time_unit_ids[]) so things are pretty much set up okay. Here''s the set up

Ok, I have a People table, a Shows table, a Techs table, and a Castmembers table. The people table has contact info about each person, the techs and castmembers tables have information about the persons specific role in that sshow. i want to call @show.techs (or somethign equivelent, I don''t want to start that code yet) and get all the techs associated with the show, and the

Is there a way to update attributes in a HABTM join table? Right now I am deleting the join and then recreating it with new attributes. I have a table "categories" and another table "items". They are both HABTM with the join table "categories_items" between them. If an item is joined to a category once, no problem, we create the join. But if an item is

I am very confused about HABTM and a form select statement that I need to implement. I have two objects - Person which has the following fields: id, firstname, lastname, email Category which has the following fields: id, name A person HABTM categories and also the reverse. I have setup the join table using a migration. All that went well. Two questions - If I want to edit a person, how do I

I have two models with an habtm relationship: Foo has_and_belongs_to_many Bars (and vice-versa, obviously). Let''s say Bar has_many Bazs (how the heck do you pluralize Baz?). It would be nice to be able to say that Foo has_many Bazs through => Bar, but this does not seem to work. Am I right, or should it be possible to do this? The best I have been able to do is this: bazs =

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, Basically I have two models: User and Godfather. The godfather table has three columns: - user_id (FK --> User) - user_godfather_id (FK --> User) - description (text) Inside each model class, I am adding the following associations: class User < ActiveRecord::Base has_many :godfathers # for user_id has_many :godfathers, :foreign_key =>

I have successfully used HABTM to create a many-to-one-to-many set of rows in one step. Now, if two objects I want to associate already exist, how do I create the join row? The Agile book mentions the ''push_with_attributes'' method. The text says this method is useful for adding additional attributes to the join row (in the example a ''read_at'' timestamp). I

I have the following: Posts belong to a User Posts may be Monitored by many Users How do you characterize this? class Post < ActiveRecord::Base belongs_to :user has_many :monitors class Monitor < ActiveRecord::Base has_many :posts, :as => user class User < ActiveRecord::Base has_many :posts # when a user *does* a post belongs_to :monitor, :polymorphic => true --

All: I have been working on making a self-referential habtm relationship that uses a join model because I want to store info about the relationship. I have been using two sections from Chad Fowler''s "Rails Recipes" as a guide, "Self-referential Many-to-Many Relationships" and "Many to Many Relationships Where the Relationship Itself has Data". So far I have

Hi all I have a DiscJockey and a Member model, each of them reference each other using habtm. josh $ script/server >> m=Member.find 1 >> dj=DiscJockey.find 1 >> m.disc_jockeys << dj >> m.disc_jockeys << dj >> m.disc_jockeys << dj Now I have 3 relations in the DB! Is this normal? Shouldn''t there an error occur, that I can only add the

Ok, David says on page 241 that sometimes a many-to-many relation with attributes are better implemented as an actual model instead of using HABTM. Well, I''ve got that situation and I can''t figure it out. All of the examples in the book have HABTM examples between 2 different tables, but I want to have a HABTM relation on 1 table with itself. (e.g., if I have a table Things,

I have two models that have a habtm relationship and it only seems to be working in one direction. The two models are "recipe" and "msn_lifestyles_feed" with a join table called "msn_lifestyles_feeds_recipes" the tables for msn_lifestyles_feed and msn_lifestyles_feeds_recipes are in the same database and the recipe table is in a completely different database. When

Hi there I have an habtm association between 2 Models. I regularly have to truncate the table on one side of the relationship and repopulate the table with a fresh csv file. I notice that f I do Model.delete_all, none of the records in my habtm join table get deleted, whereas if I use destroy_all they do. However, the overhead of using destroy_all is too great. For the amount of records I have

Hi, I posted yesterday asking how to get form tags to reference the associated objects in a habtm relationship. I was hoping for Rails Magic, but it looks like Rails doesn''t have habtm magic beyond a certain point. Here was my solution for others who might have the problem. Also, I hope someone shows me that there is a simpler way. The Database Model: class Registration <

I have a class Player, and a class Game. Game has two HABTM relationships to the Player table through seperate relationship tables. class Game < ActiveRecord::Base has_and_belongs_to_many :players, :uniq => true has_and_belongs_to_many :victors, :class_name => ''Player'', :uniq => true end When I add Player A to players, and Player B to victors, and save the

Assuming we have User, Account, and Role models, and a User has_many :accounts, through: :roles and vice-versa, with the following snippet Rails automatically creates the Role (joiner) record, but with the snippet after Rails will not. I think I''m misunderstanding how has_many through works, so I would appreciate any insight into the subject. def new @account =
