ActiveRecord: find_or_create with has_and_belongs_to_many --
I am attempting to use find_or_create on a foreign table with a
has_and_belongs_to_many relationship with my current table. I am doing
the following:
term = school.terms.find_or_create_by_code("FALL06")
the queries in the log show the expected SELECT statement to query if
there is a join table record between the school and term with code
"FALL06":
SELECT * FROM term

Polymorphic find_or_create bug
Today I just spent 3 hours (and before a demo!) trying to figure out
why my polymorphic association fields were breaking.
Turns out someone else put in a patch for this 6 months ago. I''m not
sure if its the same solution I''d use... I''d rather find_or_create
attempt to use AssociationProxy#build if its available and only
Base#new if we''re not on a proxy.

[Patch][Issue #5097] attributeless find_or_create/find_or_initialize
This patch relaxes DynamicFinderMatch to recognize find_or_create /
find_or_initialize without a trailing _by_attribute_list. I''ve found
this useful when the relevant attributes have already been built up
through a chain of associations or named scopes.
Please review, thank you!

ActiveRecord collection_select and has_and_belongs_to_many
Hello everyone, first post to the list and a relative newbie to Rails
development. Done quite a bit of JSP, PHP, HTML, XML etc and thought I would
kick the tires on Rails to see if it can speed up development for internal
applications. Anyway, I am running into a problem that is just driving me
crazy and everything I read on the net doesn''t seem to help. I was hoping

Self-Referential Many-To-Many relationships where the relationship itself has data.
Trying to model a bunch of users that have friends that are other
users. clearly a job for has_and_belongs_to_many, but the trick is,
they have ratings for their friends. I have gone through the Rails
Recipes book, and it seems like I''m trying to combine the
self-referential many-to-many recipe (12) and the many to many
relationships where the relationship itself has data recipe (16). So

HABTM being tricky
I''ve just been bodyslammed by a problem with has_and_belongs_to_many -
as far as I can tell, if it doesn''t appear at the top of other
relationship definitions it doesn''t seem to work right. For example:
class Artist < ActiveRecord::Base
has_and_belongs_to_many :genres
has_many :albums
has_many :videos
has_many :cds
has_many :collections

Re: DB Modelling the Rails way - solution by Chris Hall
Hi Chris,
Yesterday you kindly submitted an answer to my question on modelling
many to many relationships. I''ve briefly tried the proposed solution but
so far with no luck. Before I get too involved - I''d like to know if
mapping three way :join_tables is "legal" in a Rails sense. I only ask
since you put (untested) in your mail and I can''t find any docs on

has_and_belongs_to_many dual insert error ?
Hi !
(See references at the end)
I have a slight problem. Whenever I save one of my domain models, which
contains an has_and_belongs_to_many relationship with another one, the
relationships are doubled.
My domain is a series of pictures, where each picture can be tagged with
one or more words. So, a picture of my dog could be tagged "Jordy, Dog,
Dog 2005", for example.

Overriding Delete/Destroy in ActiveRecord
Anybody know how I can override delete/destroy in objects that have
has_and_belongs_to_many behavior specified?
I''m having issues overriding delete for an ActiveRecord object that
contains a has_and_belongs_to_many relationship. Delete and destroy
are properly overridden for objects that do not have
has_and_belongs_to_many relationships specified, but as soon as I add

Parent id for find_or_create method
Rails 3.1.3
I have tables, Video and Script having association,
Video 1 --- n Script
So, every Script needs the parent id, in this case, video_id.
If I simply create a new Script instance, the view renders as follows.
<%= render :partial => "new_script", :locals => { :script =>
Script.new(:video_id => @video.id)} %>

Attributes of a relationship
Hi all,
I have two types of models which I''m not sure how to model (or if it''s even
feasible) with ActiveRecord. Let me know if you''ve got any good ideas.

that you can bookmark a site, and add your own tags to it. Each person has
