我有一个这样的订单模型：
class Order < ActiveRecord::Base
belongs_to :service_address, class_name: 'Address'
belongs_to :billing_address, class_name: 'Address'
accepts_nested_attributes_for :service_address, allow_destroy: true
accepts_nested_attributes_for :billing_address, allow_destroy: true
end
class Address < ActiveRecord::Base
end
我正在努力使嵌套表单工作，以允许我以相同的形式添加两个地址。订单的params部分是这样的：
params.require(:order).permit(:contract_id, :billing_address_id, :service_address_id, :valid_from, :valid_to, :contact_person_id, :billing_mode,
service_address: [:city_id, :street_id, :number, :block, :entrance, :floor, :apartment, :_destroy],
billing_address: [:city_id, :street_id, :number, :block, :entrance, :floor, :apartment, :_destroy])
我的创建动作是这样的：
@order = Order.new(order_params)
@order.service_address = Address.new(params[:order][:service_address])
@order.billing_address = Address.new(params[:order][:billing_address])
以这种方式提交时，表单无法验证，billing_address的所有字段都会突出显示为不完整。
如果我使用service_address_params和billing_adress_params，我会收到错误undefined local variable or method 'service_address_params'
我被困在这里两天，所以任何帮助都会受到赞赏。
编辑：new
def new
@order = Order.new
@order.service_address = Address.new
@order.billing_address = Address.new
end
编辑：form
<%= simple_form_for @order, data: {validate: 'parsley'} do |f| %>
<%= f.input :contract_id, as: :hidden, :input_html => { :value => @contract_id } %>
<%= f.input :same_billing_address, as: :hidden, :input_html => { :value => 0 } %>
<%= f.error_notification %>
<%= render :partial => 'order_data', :locals => { f: f } %>
<%= render :partial => 'service_address' %>
<%= render :partial => 'billing_address' %>
<div class="form-actions">
<%= f.button :submit %>
</div>
<% end %>
地址的部分内容：
<%= simple_fields_for :service_address do |sa| %>
<div class="form-inputs" id="inputs-step2">
<%= sa.input :city_id, label: 'Oras', collection: @cities, input_html: { 'data-parsley-group' => "block2", :required => true, id: 'service_address_city_id' } %>
<%= sa.input :street_id, label: 'Strada', collection: @streets, input_html: { 'data-parsley-group' => "block2", :required => true, id: 'service_address_street_id' } %>
<%= sa.input :number, label: 'Numar', input_html: { 'data-parsley-group' => "block2", :required => true } %>
<%= sa.input :block, label: 'Bloc' %>
<%= sa.input :entrance, label: 'Scara' %>
<%= sa.input :floor, label: 'Etaj' %>
<%= sa.input :apartment, label: 'Apartament' %>
</div>
<% end %>
结算地址部分：
<%= simple_fields_for :billing_address do |ba| %>
<div class="form-inputs" id="inputs-step3">
<%= ba.input :city_id, label: 'Oras', collection: @cities, input_html: { 'data-parsley-group' => "block3", :required => true, id: 'billing_address_city_id' } %>
<%= ba.input :street_id, label: 'Strada', collection: @streets, input_html: { 'data-parsley-group' => "block3", :required => true, id: 'billing_address_street_id' } %>
<%= ba.input :number, label: 'Numar', input_html: { 'data-parsley-group' => "block3", :required => true } %>
<%= ba.input :block, label: 'Bloc' %>
<%= ba.input :entrance, label: 'Scara' %>
<%= ba.input :floor, label: 'Etaj' %>
<%= ba.input :apartment, label: 'Apartament' %>
</div>

答案 0 :(得分：1)
首先，将accepts_nested_attributes_for与belongs_to一起使用是痛苦，而且非常棘手。其次，有很多错误。 code.I将逐一解释。
错误＃1
您的new方法应该是这样的
def new
@order = Order.new
@order.build_service_address
@order.build_billing_address
end
在create方法中，您不需要这些行，请将其删除。
@order.service_address = Address.new(params[:order][:service_address])
@order.billing_address = Address.new(params[:order][:billing_address])
错误＃2
您的order_params方法应该是这样的
def order_params
params.require(:order).permit(:contract_id, :billing_address_id, :service_address_id, :valid_from, :valid_to, :contact_person_id, :billing_mode,service_address_attributes: [:city_id, :street_id, :number, :block, :entrance, :floor, :apartment, :_destroy],billing_address_attributes: [:city_id, :street_id, :number, :block, :entrance, :floor, :apartment, :_destroy])
end
请注意更改service_address_attributes和billing_address_attributes
错误＃3
您没有将locals传递给service_address和billing_address部分内容。
这些行
<%= render :partial => 'service_address' %>
<%= render :partial => 'billing_address' %>
应该是这样的
<%= render :partial => 'service_address',:locals => { f: sa }%>
<%= render :partial => 'billing_address',:locals => { f: ba } %>
<强>更新
尝试在partials
main form
<%= f.simple_fields_for :service_address do |sa| %>
<%= render :partial => 'service_address',:locals => { f: sa }%>
<% end %>
<%= f.simple_fields_for :billing_address do |ba| %>
<%= render :partial => 'billing_address',:locals => { f: ba } %>
<% end %>
然后更改service_address和billing_address partials中的代码
#_service_address.html.erb
<div class="form-inputs" id="inputs-step2">
<%= f.input :city_id, label: 'Oras', collection: @cities, input_html: { 'data-parsley-group' => "block2", :required => true, id: 'service_address_city_id' } %>
