ruby on rails 4 - ActiveAdmin Nested Form multiple select -
i'm trying product_suppliers update via product form. form displays suppliers in supplier table doesn't update join table. not sure error lies. index , show show correct details edit not updating join table. starting go around , around in circles on one.
update: changing form below has got me close. still not updating join table. delete works expected if manually add rows join table. display , can deleted. saving adds new product_id row not associated supply_company_id value. figure attribute issue cant see it.
app/models/product.rb

class supplycompany < activerecord::base has_many :products, :through => :product_suppliers has_many :product_suppliers, :foreign_key => 'supply_company_id' end app/models/product_supplier.rb
class productsupplier < activerecord::base belongs_to :product belongs_to :supply_company accepts_nested_attributes_for :product accepts_nested_attributes_for :supply_company end /app/admin/product.rb

turns out multipart: :true in code. once removed below code worked expected.
