HABTM: deleting records based on attributes

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

HABTM association with own class?

Prevent duplicate HABTM associations
Hi,
I am trying to restrict duplicate has_and_belongs_to_many associations.
I tried to find support for a association validation for duplicates but
couldn''t find anything.
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.

and belongs to many Loan Types. This is so I can select multiples of
each in my order entry screen via checkbox groups.

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

No Magic for HABTM forms?
Hi,
I posted yesterday asking how to get form tags to reference the
associated objects in a habtm relationship. I was hoping for Rails
Magic, but it looks like Rails doesn''t have habtm magic beyond a
certain point.
Here was my solution for others who might have the problem. Also, I
hope someone shows me that there is a simpler way.

Multiple HABTM relationships with self ???
I need to have a table related to itself via a join table. Will HABTM
support this? That is:

end
More importantly -- how does RoR support MULTIPLE self-joins? I.e., to
relate the table to itself via multiple join tables.
SFAIK, HABTM won''t support multiple
