改革創業板：使用多種形式的一種模式

Question

我正在使用改革創業板在我的網上商店做結帳的表單對象。我有Checkout表單，其中包含Order模型的屬性，它與Address模型有關聯。

問題是訂單模型具有相同的地址模型中的兩個聯想：

class Order < ActiveRecord::Base 
    #... 
    belongs_to :billing_address, :class_name => 'Address' 
    belongs_to :shipping_address, :class_name => 'Address' 
    #... 
end 

所以我需要建立自己的Google Checkout形式使用的地址模式的兩倍。我曾經申請的臨時方法很簡單。但它工作正常：

class Checkout < Reform::Form 
    extend ::ActiveModel::Callbacks 
    #... 
    property :billing_address, populate_if_empty: Address do 
    property :firstname 
    property :lastname 
    property :address1 
    property :address2 
    property :phone 
    property :city 
    property :zipcode 
    property :country_id 
    property :billing_address_for_id 
    property :shipping_address_for_id 

    validates :firstname, 
       :lastname, 
       :address1, 
       :phone, 
       :city, 
       :zipcode, 
       :country_id, 
       presence: true 

    # provided by phony_rails gem 
    # validates phone number to be correct and plausible 
    # without country accordance 
    validates :phone, phony_plausible: { ignore_record_country_code: true } 

    # provided by validates_zipcode gem 
    # validates zipcode to be correct due to country alpha2 code 
    validates :zipcode, zipcode: { country_code: :country_code } 
    end 

    property :shipping_address, populate_if_empty: Address do 
    property :firstname 
    property :lastname 
    property :address1 
    property :address2 
    property :phone 
    property :city 
    property :zipcode 
    property :country_id 
    property :billing_address_for_id 
    property :shipping_address_for_id 

    validates :firstname, 
       :lastname, 
       :address1, 
       :phone, 
       :city, 
       :zipcode, 
       :country_id, 
       presence: true 

    # provided by phony_rails gem 
    # validates phone number to be correct and plausible 
    # without country accordance 
    validates :phone, phony_plausible: { ignore_record_country_code: true } 

    # provided by validates_zipcode gem 
    # validates zipcode to be correct due to country alpha2 code 
    validates :zipcode, zipcode: { country_code: :country_code } 
    #... 
    end 

但很明顯，重複的代碼必須重構。在那裏，我發現我不能提出任何工作解決方案。我最後的嘗試是像以下：

class Checkout < Reform::Form 
    extend ::ActiveModel::Callbacks 
    #... 
    property :billing_address, populate_if_empty: Address, form: BillingAddress 
    property :shipping_address, populate_if_empty: Address, form: ShippingAddress 
    #... 
end 

class BillingAddress < Reform::Form 
    extend ::ActiveModel::Callbacks 
    include Address 
end 

class ShippingAddress < Reform::Form 
    extend ::ActiveModel::Callbacks 
    include Address 
end 

module Address 
    include Reform::Form::Module 

    property :firstname 
    property :lastname 
    property :address1 
    property :address2 
    property :phone 
    property :city 
    property :zipcode 
    property :country_id 
    property :billing_address_for_id 
    property :shipping_address_for_id 

    validates :firstname, 
      :lastname, 
      :address1, 
      :phone, 
      :city, 
      :zipcode, 
      :country_id, 
      presence: true 

    # provided by phony_rails gem 
    # validates phone number to be correct and plausible 
    # without country accordance 
    validates :phone, phony_plausible: { ignore_record_country_code: true } 

    # provided by validates_zipcode gem 
    # validates zipcode to be correct due to country alpha2 code 
    validates :zipcode, zipcode: { country_code: :country_code } 
end 

有了這樣的設置

@checkout = Checkout.new(@order) 

是給我的錯誤

undefined method `active_record' for #Declarative::Heritage:0x007ff6ea6fb038 

那麼，有在改革的任何標準的方法來使事情上述工作？或者有人可以告訴我做錯了什麼？謝謝！

Answer 1

我意外地找到了答案。實際的問題是我的模塊名稱是地址什麼是我的一個模型的確切名稱。這顯然有些衝突。所以我將地址更改爲AddressModule。

而我的工作設置爲：

class Checkout < Reform::Form 
    extend ::ActiveModel::Callbacks 
    #... 
    property :billing_address, populate_if_empty: Address, form: BillingAddress 
    property :shipping_address, populate_if_empty: Address, form: ShippingAddress 
    #... 
end 

class BillingAddress < Reform::Form 
    extend ::ActiveModel::Callbacks 
    include AddressModule 
end 

class ShippingAddress < Reform::Form 
    extend ::ActiveModel::Callbacks 
    include AddressModule 
end 

module AddressModule 
    include Reform::Form::Module 

    property :firstname 
    property :lastname 
    property :address1 
    property :address2 
    property :phone 
    property :city 
    property :zipcode 
    property :country_id 
    property :billing_address_for_id 
    property :shipping_address_for_id 

    validates :firstname, 
      :lastname, 
      :address1, 
      :phone, 
      :city, 
      :zipcode, 
      :country_id, 
      presence: true 

    # provided by phony_rails gem 
    # validates phone number to be correct and plausible 
    # without country accordance 
    validates :phone, phony_plausible: { ignore_record_country_code: true } 

    # provided by validates_zipcode gem 
    # validates zipcode to be correct due to country alpha2 code 
    validates :zipcode, zipcode: { country_code: :country_code } 
end
