has-many-through

I have three models:

Service
has_many :prices
has_many :groups, through: prices

Price
belongs_to :service
belongs_to :group

Group
has_many :prices

I want to have an input field (Simple_Form) for every price. In views/services/_form.html.haml I do:

simple_form_for @service do |f|
    simple_fields_for :groups do |g|
        simple_fields_for :prices do |p|
            p.input :price

With this setup I only get input fields for already saved prices. How I can get a price field for every group? I tried to do it manually, but it got really nasty and didn't work either.

Thanks for any ideas!
