Hi there,

Just a simple question I guess, but I am unable to find an anwser…

How to delete a hmabtm relation?

Any help will be appreciated :slight_smile:

Thanks,

Try this…

@user = User.find(session[:current_user])
@tag = Tag.find(params[:tag_id])
@tag.users.delete(@user)

where Tag habtm User

I’m pretty sure that you need to pass the actual @user object, not just
the id,
can’t quite remember…

Hope it helps :]
