Ruby on Rails: Has and belongs to many relationship: how do I destroy a relationship?

Question

This is a lot harder in code, than in real life. =)
But anyway,
My Users have managers, and vice versa...

How do I remove the relationship?

@selected_user = User.find(params[:id])
@selected_user.managers.delete_if{|x| x.standard_user_id == params[:id].to_i}

This is a self referential has and belongs to many relationship, so I have another table that has only two columns of foreign keys, both pointing to the Users table. This lookup table does not have a model.

Answer 1

Doesnt this work ? @selected_user.managers.each{|x| x.destroy!} or Managers.delete_all "standard_user_id = params[:id]"

Answer 2

tell her she is fat.

Answer 3

    @report = User.find(params[:report])
    @manager = User.find(params[:manager])
    @manager.standard_users.delete(@report)

Managers have standard users standard users have managers
