Edit/create does not work after converting habtm to has_many through

[p k]

I'm using Rails 2.3 and the AS plugin for the same branch (2.3). This
worked fine till now, but for reasons beyond my control, I need to
convert my existing HABTM associations to has_many through
associations.

I have made the corresponding changes (has_many through) in my
original models (say, a and b) and added a third model (a_b) for the
association table. I also added an autoincrement id column to the
association table.

The list of entries in the database for model a still show up fine
but, now when I try to edit the list of associated entries (model b)
that model a points to, the form submits fine, but does not update
anything. It shows the same original list of associated entries.

Do I need to make any other changes to get this working? Or does AS
only support HABTM associations?

Let me know if you need more info.

Thanks,
PK

Has many through should work. Are you excluding a_b column? Is sent form data
right? You can get it in log file.

Thanks for the reply Sergio. It did point me in the right direction
where I had 'b' as one of the columns in the a_controller, instead of
a_b.

Now all updates work fine except when I remove an association between
a and b. Say I remove a value "b3" associated with "a1", in the a_b
table, the value for b_id is changed to NULL instead of deleting this
row. In other words, the association is not destroyed, but one of the
values is changed to NULL.

How do I configure this to destroy the row in the join table, rather
than storing the id as NULL?

Thanks,
PK

Adding :dependent => :destroy to your "a" has_many association should
do the trick.
