Active Record Querying HABTM

I am new to rails and stuck on one Querying issue. Here is the situation.

Model: Category class Category < ActiveRecord::Base        has_and_belongs_to_many :postings        has_and_belongs_to_many :volunteers end

Model: Posting class Posting < ActiveRecord::Base        has_and_belongs_to_many :categories end

Model: Volunteer class Volunteer < ActiveRecord::Base        has_and_belongs_to_many :categories end

Sounds like you want a "has_many :through" relationship.
