Hello everyone I am very much confused about specifying the relation in the following one. I had Item, Invoice, Invoicedetail model. Item table contains - id and name,unit_price fields. Invoice table contains - id, invoice_number and date Invoicedetails - invoice_id, item_id, quantity, unit_price fields. I had mentioned the following relations. class Item < ActiveRecord::Base has_many :invoicedetails has_many :invoices, :through=>:invoicedetails end class Invoicedetail < ActiveRecord::Base belongs_to :item belongs_to :invoice end class Invoice < ActiveRecord::Base has_many :invoicedetails has_many :items, :through=>:invoicedetails May anyone suggest I am specifying the correct relation or not? If it is wrong please give correct one and suggestions for understanding the specification of relations more. Thanks in advance
