similar to: Deleting the association entry for has_and_belongs_to_many when one object is destroyed

Hi, I''m currently having the situation where I have to implement a polymorphic has_and_belongs_to_many by introducing an in between model that handles all the "has_many :as" and "belongs_to :polymorphic" association implementations... and is not doing anything else. Thing I don''t like it here is, I am unnecessarily loading AR instances only to execute SQL

hi, I found a bug in ActiveRecord association SQL INNER JOIN codes. in has_many, has_one, habtm and belongs_to queries the foreign key is determined from the table name of reflection and self. but that''s worng because if you use a global prefix or suffix for your tables the foreign keys will be in format of PREFIX_CLASSNAME_SUFFIX_id which is wrong, because it breaks the advantage of

Can anyone help me find a code coverage tool in ruby? What I want is: given a set of tests that I run, what lines of my code and what routines are covered. And also a list of uncovered routines and tests. I couldn''t find an open source one out there... -- www.kenlet.com

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.. Guys new plugin again Foreign Key Associations is a plugin that automatically creates associations based on foreign-keys. The associations are created at runtime-ie. as your ActiveRecord models are loaded-so they will always be up-to-date. For example, given a foreign-key from a customer_id column in an orders table to an id column in a customers table, the plugin creates:

Hello all, I have the following models: class Sku < ActiveRecord::Base has_and_belongs_to_many :options end class Option < ActiveRecord::Base has_and_belongs_to_many :skus end By default if I destroy an Option any relationships between Options and Skus will be removed as well. But, I want to prevent an Option from being destroyed when it is associated with a Sku in the options_skus

Hey Guys, I''m getting a peculiar bug working with Observers and has_one associations. When a has_one association is invoked by an Observer it always returns null. I looked in the development.log file and the SQL for the has_one association isn''t even being executed. On the other hand, when I replace the has_one association with just a hand crafted method, it does get called

Hi there, I have a model for a Film, which: has_and_belongs_to_many :artists has_many :stills has_one :preview_image, :class_name => "Still", :conditions => "priority=''main''" the has_one:preview_image and has_many:stills obviously draw from the same table. I was

I''m having a problem with belongs_to and has_and_belongs_to_many.

I''m having a problem with a has_and_belongs_to_many (habtm) association between two models with extra attributes. I''m writing a comic book database, and each issue has many creators on it. Thing is, some creators perform multiple duties. They may write one issue, draw another, etc. However, if I add a creator twice to an issue and try to delete it, it removes both creators:

Hi... Isn''t there a proper way or hack/workaround for the following? * For the example with unfortunate disabilities.. look below,,, Usage of has_* (associationmethods) do {def with_deleted AccociatedModel#with_scope} {Paranoid''s#find_with_deleted}...

Hi. I''m hoping somebody can tell me that I''ve just gotten my syntax wrong and I can in fact do what I want to do. I''ve got a Group, and a Group has_many Campaigns. Campaign has_and_belongs_to_many Users (and, naturally, vice versa). So I''ve got a groups table, a campaigns table (that has a group_id), a campaigns_users join table (with campaign_id and

Hi, I''m struggling with something that must be very common pattern, and want to do it the correct rails/ruby way but am a bit dense ! I have users - an admin user, registered users and a guest user (using ModelSecurity) For many of linked associations I want the admin to be able to list or edit all instances, the registered user only their own one and guest none at all. So somehow I
