similar to: What is has_many :through really buying you over HABTM?

I just took my HABTM and turned it into a :through since my join table has another "non-joiny" attribute. I went from this: has_many_and_belongs_to :jobs, :join_table => ''tablename'', :foreign_key => ''x'', :association_foreign_key => ''y'' to this: has_many :jobs, :through =>

All, I''ve heard recently about has_many :through as a necessary alternative to HABTM (when the join table has it''s own id column, say, in a legacy schema). However, is the prevailing Rails wisdom now that one should use has_many :through in _all_ cases? If so, why? Thanks, Wes -- Posted via http://www.ruby-forum.com/.

For a while, I''ve been getting that HMT is replacing HABTM. It appears that HMT can do all of what HABTM can do and more. The question is: Should I stop using HABTM? Let''s take a simple case: A case has many categories For a given category, there are certain valid statuses Category has_and_belongs_to_many :statuses Status has_and_belongs_to_many :categories Question: Is

All, I''m building model objects for existing tables that I cannot modify. In AWDWR, Dave says "Note that our join table has no id column...The second reason for not including an id column in the join table is that AR automatically includes all columns from the join tables when accessing rows using it. If the join table included a column called id, its id would overwrite the id

All, I''ve come across a confusing problem when attempting to run unit tests for an application on OSX (works on Windows). I''m receiving the following error: `load_specification'': undefined method `parse'' for Time:Class (NoMethodError) This is also confusing because I can''t figure out how the error appeared.

We have tables Users and Communities linked by has_an_belongs_to_many. The join table Communities_Users has additional fields [ is_active, is_blocked, join_date] etc. These are populated using @user.push_with_attributes(:is_active => true,...). Later on how do we update or retrieve the attributes in the link table for a given user or a community with doing it explicitly using SQL? Thanks,

Hi there I need to store additional attributes on join table. Searching the Wiki [1] revealed two possible methods: 1) push_with_attributes, as described by Justin Palmer [2]. Unfortunately, "this method is now deprecated" [3]. Even if it wasn''t, there seem to be inherent problems with that approach, for example with updating those additional attributes, though Joshua Muheim

All, Win XP SQL Server 2000 Rails 1.1.6 (AR 1.14.4) I have two objects (Job and Warning) in a HABTM relationship.

Lets say you had a pretty decent job, but your company mandated use of emacs. The poaching employer offers you a free copy of Textmate(tm). Would you jump ship solely in order to use Textmate at company B? Cheers, Dave -- Posted via http://www.ruby-forum.com/.

Hi, I''m trying to figure out the best way to protect images uploaded by users who may wish to keep them private. For example, if they are uploaded in the default file_column location (/public/blah/blah/1/) then someone can simply type the URL http://www.blah.com/blah/blah/1 and get the image. I can store the images in a non-public directory in the rails app (ie: /railsapp/images/X/)

Hi, everyone, I''m currently running a Rails 1.0 project using lighttpd-1.4.9 behind Apache 2 on RHEL 3. My fcgi process (I''m only using one right now) always hangs after some time, which is something I haven''t experienced before (e.g., I''ve run this same app. on a TextDrive account and it works fine there). So ... any ideas on what could be causing this?

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>
