No, that’s expected behavior.
HABTM does not use a model table.
If I have
items
id
name
And
subjects
id
name
HABTM will expect a table that looks like this:
items_subjects
book_id
category_id
There is no ‘id’ field in this table because it shouldn’t need one.
You should be creating an item and then doing
@item << @subject
to add the subject.
You shouldn’t need a model for items_subjects
Also, unless you’re doing something more than what I think you’re doing,
you don’t need any of this:
Item.establish_connection(
:adapter => ‘mysql’,
:host => ‘localhost’,
:username => ‘root’,
:password => ‘password’,
:database => ‘retainit_test’
)
Subject.establish_connection(
:adapter => ‘mysql’,
:host => ‘localhost’,
:username => ‘root’,
:password => ‘password’,
:database => ‘retainit_test’
)
Items_Subjects.establish_connection(
:adapter => ‘mysql’,
:host => ‘localhost’,
:username => ‘root’,
:password => ‘password’,
:database => ‘retainit_test’
)
That’s why database.yml is for…
Hope that helps… Have you searched the WIKI for HABTM? Do you have the
Agile book?
Let me know if that’s clear as mud
