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

Hi. I get this error: ** ActiveRecord::ReadOnlyRecord ** When i try to update a table called characters_learning_abls that is a habtm relation between characters and learning_abls.

Hello, I have a has_and_belongs_to_many relationship that I''ve realized I need to add additional attributes to. So I''m converting it to a has_many :through (HMT) relationship. This is the first time I''ve used an HMT, and it seems like I''m using too much code. I couldn''t figure out how to get the join model objects to update automatically as a result of

Hello all, I have an Order object that has and belongs to many Products and has and belongs to many Loan Types. This is so I can select multiples of each in my order entry screen via checkbox groups. I''m having some trouble with saving multiple HABTM associations for a single model object; only the first HABTM association declared in the model will save during the initial @order.save

How does one use a <select> for a habtm field? I''m having trouble getting it to work. Here''s my html: <div> <p><label for="projects">Project</label><br/> <select id="schedule_projects" name="schedule[project_ids][]" multiple="multiple" size="10"> <%=

Hope someone can tell me what''s up, because this has me baffled. I have an Image model, and a Provider model. Both are defined as "has_and_belongs_to_many" relating to each other. In my image form partial, I have a bit of AJAX generating the provider_ids array dynamically from a provider AJAX search on the same page. So for example, each time I click on a provider name that

Hello forum readers, Let''s say i have two models: Person and Role (i replicated the problem with Post & Tag as well, as i thought the problem was linked to some application-specific rights problem, but it wasn''t). In Person, attr_accessible role_ids is declared, so it accepts an array of Role ids as an argument when creating / updating. If i fire up the rails console and

Hello all, I''m trying to create a HABTM checkbox action that adds/updates ''users'' to a ''project''. I have the following laid out. --------------------- TABLES --------------------- create_table "assignments", :id => false, :force => true do |t| t.column "project_id", :integer, :default => 0, :null => false

Hello List, I''m a bit spent on this problem, and my code might be whack. I seem to be encountering a problem where the primary key on a join table is not being resolved correctly. I will elaborate after some code bits. I am creating the join table using migrations, and relevant model code is this: class Post < ActiveRecord::Base has_and_belongs_to_many :records

I have two ActiveRecord classes that point at each other with a "has_and_belongs_to_many" (habtm) relationship using a join table. The join table has an a few additional columns besides the _id columns. For those of you with the Agile Web Dev w/ Rails book, it''s exactly the same setup as the articles<->articles_users<->users example on p240. The habtm

I have a photographers app that requires giving access to galleries for users. in one part, I want to be able to define gallery access for a user seperate from updating any of the user info. I have this function: def edit_access @user = User.find(params[:id]) @user.galleries = Gallery.find(params[:gallery_ids]) if params[:gallery_ids] if @user.update_attributes(params[:user])

Hello, I seem to have run into a problem that I can''t seem to make any headway on. I''ve searched the mailing archives, google''d for the appropriate keywords and have checked up with the folks on IRC but I can''t seem to find a solution. My problem is as such. I have a web application that has various controllers which work fine. I''ve added a

In my mind, it should work like this: <%= select ''item'', ''category_ids'', Category.find(:all).collect {|c| [c.name, c.id] }, {}, {:multiple=>true, :size=>20} %> Then Rails should automatically populate and update HABTM on that. As it is now, the above won''t work (I created a getter in item''s model that returns an array of

I''ve looked through the docs and the wiki and can''t figure out how to go about generating select options and the update function for an item that has a HABTM relationship. I have a ''parks'' table and the park model has a HABTM to the ''states'' table. On the park edit page, I''d like a multiple select box to appear with all states show,

Ok, so I have two models that HABTM each other. Companies UserAccounts When creating a new user account, this works: @company.user_accounts << @user This works with or without a subsequent save of @company. And the association is set properly but this does nothing (fails silently): @user.companies << @company This fails both when I do and don''t save @user afterwards.

I know there have been threads on this before but I was thinking shouldn''t multiple collection_select automatically update habtm relations when you update_attributes? In order to get multiple collection_select to work I use: collection_select(:user, :group_ids, Group.find(:all), :id, :name,{},{:multiple=>'''',:name=>''group[id][]''}) In fact if I

I have a problem related with the HABTM relationships with checkboxes. I''ve got a profile and a service model, both related with has_and_belongs_to_many. The problem is that i can insert new data in the profiles_services table, however, i cant delete already existing data. What could be the problem? --~--~---------~--~----~------------~-------~--~----~ You received this message

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

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>

Hello guys. I was able to figure out that my "stack level too deep" error I was getting with my HABTM destroy method was the result of a bug in rails 1.0. I upgraded to 1.1.2 and now the views and any console-run commands for destroying AR objects linked together via HABTM work just fine. I have HABTM setup between stories and submissions. The issue is that the destroy methods in
