similar to: question/problem with habtm and "include?"

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 am new to ROR, and can''t seem to get HABTM to cooperate entirely... however I might be abusing it! Before I try a different strategy I thought I''d ask here and see if I''m missing something simple. So say Projects and Companies are related. Projects can have multiple Companies, and Companies can be on multiple Projects. But, the same Company can also

I have two models Role and Task ..and a join table/model RoleTask Now both roles and tasks have id as a primary key and name which is a unique identifier I want the join table to hold role_id and task_name I''ve tried using habtm with foreign key and association foreign keys set up and I''ve tried using has_many :through ..but they all seem to someone want to work with the

Chris, Finally got time to fully play with your suggestions. Had to re-code a bit of stuff but the concept works - just like a bought one :~). Many thanks for the solution, Kind Regards, Eric.

I have a role-based authorization system exactly like the one from Rails Recepies. I am looking to return all rights however in my view I want to highlight the rights that are associated with the currently selected role (passed in through @params[:id]). Schema: create_table "rights", :force => true do |t| t.column "name", :string t.column "controller",

An app I''ve been developing has been chugging along nicely, but around the time I added a new join model a couple of commits ago, my development environment has been acting screwy. 1. When there''s an error, the error messages and tracebacks are not being returned to the browser. The browser keeps the connection alive indefinitely. 2. Stopping the request from the browser

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

Hi, I''m trying to figure the most efficient way to model the following. I can think of at least two ways to relate the tables but from a client/server perspective! I''m wondering how to best (and elegantly)relate them from an AR perspective. A project has many people, A person can work on many projects at any time, A project has many roles, A role is performed by a person, A

I''ve been bringing up a good basica framework for applications at work. To give decent security I''ve been implementing the Rails Recipie for Authorization of function calls modeled on the book''s implementation. (Changes for our environment were added..but are minor.) Since I initially let Rails create the join table between two data tables with a HABTM relationship....I

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 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

I am using the proven authorization plugin to defines roles for users, so I can get all groups where a user is ''member'' @groups = current_user.group_memberships I have an habtm association between groups and events class Group < ActiveRecord::Base has_and_belongs_to_many :events .. class Event < ActiveRecord::Base has_and_belongs_to_many :groups I am trying to list

Is there an easy way to paginate HABTM? Something like (which doesn''t work): @pages, @directories = paginate :directories, :include=>:categories, :per_page=>ITEMS_PER_PAGE directories and categories have an HABTM association. Joe -- Posted via http://www.ruby-forum.com/.

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

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

Hi everyone, For one of our projects we have a need to deploy and maintain a demo. As a result I''ve attempted to setup a set of rake tasks for the job. My goal is have one rake task called "deploy_demo" which purges the database, migrates to the current schema, and loads the db from a set of fixture files in a specified location. I''ve written two new tasks the perform

Hi, I have a strange problem with testing classes which have a HABTM relation. It seems that while running my tests with rake the fixture for the association table is not loaded - as a result I get a failure on a test which simply checks the number of associated elements - it says it''s 0 although there should be one. The weird thing is that when I run the tests with rcov
