Help needed on STI syntax
Struggling a little with getting the syntax right for a STI model. Prob just being a bit dense. Couple of questions I''m hoping you guys can answer: Assume here I''ve got: class Person class Manager < Person class Slave < Person 1) How does person[:type] differ from person.type when type is the column used to specify the subclass. They seem to output the same

Scaffolding support for many-to-many editing (habtm)?
Like with simple table editing, there are also typical ways of how a user usually interacts with one-to-many or many-to-many relations. For example, one would show the fields of one row of table1 in the screen and below a line-by-line view of all associated entries in table2. Then, one could press an "Edit" button and add or delete rows from table2 to this entry of table1,

extra attributes in habtm
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>

"Stack Level Too Deep" issue in HABTM Unit / Functional Test
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

Is HABTM Dying?
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

HABTM vs. using has_many :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/.

Rails 1.1: Is HABTM obsolete?
Does the new has_many :through and belongs_to :through obsolete (well, replace and essentially deprecate) has_and_belongs_to_many? Joe -- Posted via http://www.ruby-forum.com/.

HABTM -VS- belongs_to/has_many, for self-referential joins
Ok, David says on page 241 that sometimes a many-to-many relation with attributes are better implemented as an actual model instead of using HABTM. Well, I''ve got that situation and I can''t figure it out. All of the examples in the book have HABTM examples between 2 different tables, but I want to have a HABTM relation on 1 table with itself. (e.g., if I have a table Things,

Prevent duplicate HABTM associations

I understand I could use :uniq=>true on the model association but this would only prevent it from displaying duplicates, I want to stop duplicate associations being inserted in the first place.
