我有三個車型分別是發票,InvoiceDetail和產品。 的發票有許多InvoiceDetails和InvoiceDetails所屬的發票和產品Rails的活動模型串行 - 添加嵌套屬性2級模型
我分別對所有三種型號定義序列化,但是,當我取發票,我無法獲取產品屬性。
發票型號:
class Invoice < ApplicationRecord
has_many :invoiceDetails, inverse_of: :invoice
belongs_to :customer
accepts_nested_attributes_for :invoiceDetails
end
InvoiceDetai型號
class InvoiceDetail < ApplicationRecord
belongs_to :invoice
belongs_to :product
end
產品型號
class Product < ApplicationRecord
belongs_to :company
belongs_to :category
belongs_to :user
end
個串行器
class InvoiceSerializer < ActiveModel::Serializer
attributes :id, :total_amount, :balance_amount, :created_at
belongs_to :customer
has_many :invoiceDetails
end
class InvoiceDetailSerializer < ActiveModel::Serializer
attributes :id, :quantity, :discount, :subtotal
belongs_to :product
end
class ProductSerializer < ActiveModel::Serializer
attributes :id, :name, :mrp, :sp, :cp, :stocks, :isPublished
has_one :category
end
當我取發票: 的JSON輸出不包括產品屬性。

有產品'無關聯'和'invoice_detail'這可能是原因。 – Pavan
它們之間有一個關聯,invoice_detail屬於產品以及發票 – Paras
這還不夠!我建議你閱讀協會! – Pavan
