Re: Validate HABTM

I have the same problem.

It saves automatically but validation won't run. To me it seems like
the logical place to put these validation rules is on the join table
in the HABTM relationship. Ie PostsTag model, but unfortunately it
doesn't run.

It's weird that it will happily save the data, but it won't validate
by default.
