Rails 3 - Active_admin select nested object in many to many

Question

I have two models. Deals and Stores. I want to add already created Deals when creating a Store. I want to add already created Sores when creating a Deal. I am trying to use f.has_many, but I can't make it working.

My relationship is built using has_and_belongs_to_many :deals and has_and_belongs_to_many :stores (in the models)

My store custom form has the following:

f.inputs "Deals" do
    f.has_many :deals do |deal|
         deal.input :id, :as => :select, :include_blank => false
    end
end

I don't know how to add deals to the store.

Any help?

Answer 1

Just checking, but do you have an

accepts_nested_attributes_for :deals   #, :allow_destroy => true

declaration in your Store model, and an

accepts_nested_attributes_for :stores 

declaration in your Deals model?

You may want to check these two pages:
