控制台中不允许的参数

Question

型号

prd_item.rb

has_many :prd_allisland_flat_deliveries, 依赖: :destroy, inverse_of: :prd_item

prd_allisland_flat_delivery.rb

belongs_to :prd_item

在主窗体中

 <%=  p.fields_for :prd_allisland_flat_deliveries  do |i| %>

   <%= render(:partial => 'prd_allisland_flat_delivery_field', :locals => {:f => i})%>
 <% end %>

在 prd_allisland_flat_delivery_field 表单部分

   <div class="row" style="padding-bottom: 25px">
          <div class="col-md-2"></div>
          <div class="col-md-4">
            <%= f.label :delivery_period %>
          </div>



            <div class="col-md-4">


     <%= f.text_field(:delivery_period, {placeholder: '0', class: 'form-control input_border input_field_text_align_right'})%>
          </div>
          <div class="col-md-2"></div>
   </div>

        <div class="row" style="padding-bottom: 25px">
          <div class="col-md-2"></div>
          <div class="col-md-4">
            <%= f.label :delivery_rate %>
          </div>
          <div class="col-md-4">
            <%= f.text_field(:delivery_rate, {placeholder: 'Rs. 0.00', class: 'form-control input_border input_field_text_align_right'})%>
          </div>

        </div> 

在prd_item控制器中

**定义新

@item = PrdItem.new

@item.prd_allisland_flat_deliveries.build

结束**

写完这个创建方法

**

if @item.save

  if @item.delivery_type == 1

     @all_island_flat = @item.prd_allisland_flat_deliveries.build(item_params[:prd_allisland_flat_deliveries_attributes])
    @all_island_flat.save
  end

结束**

item_params

定义项目参数

    params.require(:prd_item).permit(:item_name, :brand, :item_no, :short_description, :long_description, :prd_type_id, :usr_vendor_property_id, :price,:base_price, :price_discount, :percentage_discount, :stock_count, :availability, :tags, :remove_image, :delivery_type , :min_stock_count,

                                 prd_item_images_attributes: [:id, :image, :description, :link, :_destroy ],

                                 prd_temp_variation_stores_attributes: [:id, :product_variations, :variation_items, :_destroy],
                                 prd_temp_compound_stores_attributes:[:id,:compound, :compound_item, :_destroy],
                                 prd_temp_spec_stores_attributes:[:id,:compound, :compound_item, :_destroy],
                                 prd_allisland_flat_deliveries_attributes: [:id,:delivery_period,:delivery_rate],
                                 prd_province_vise_deliveries_attributes: [:id , :province_name , :delivery_rate, :delivery_period]

                                 )

rails 控制台获取 Unpermitted 参数：prd_allisland_flat_deliveries

谁能解释原因

如果图片不清晰

参数：{"utf8"=>"✓", "authenticity_token"=>"ZqJOX4nMmWyVG2CxJznKKxLLsUkG+4ndBFdvxfx2TPouiQkIbYfvQ00moCdqFZWPd0nJ4ipCVY9JhVToESDCoQ==", "prd_item"=>{"item_name"=>"666", ", "品牌"=>"" , "prd_type_id"=>"", "short_description"=>"", "long_description"=>"", "tags"=>"", "prd_item_images_attributes"=>{"0"=>{"_destroy"=> "false", "description"=>"", "link"=>""}}, "base_price"=>"655", "price"=>"688 ", "price_discount"=>"5", "prd_temp_spec_stores_attributes"=>{"0"=>{"spec_item"=>"", "spec"=>""}}, "prd_temp_variation_stores_attributes"=>{"0" =>{"product_variations"=>"", "variation_items"=>""}}, "prd_temp_ Compound_stores_attributes"=>{"0"=>{"compound_item"=>"", "compound"=>""}}, "stock_count"=>"55", "min_stock_count"=>"5", "可用性" =>“可用”，“delivery_type”=>“1”，“prd_allisland_flat_deliveries”=>{“d elivery_period"=>"255", "delivery_rate"=>"22"}, "prd_province_vise_deliveries"=>{"delivery_rate"=>"", "delivery_period"=>""}}, "commit"=>"添加产品"}

不允许的参数：prd_allisland_flat_deliveries、prd_province_vise_deliveries

SQL (1.0ms) INSERT INTO "prd_allisland_flat_deliveries" ("prd_item_id", "created_at", "updated_at") 值 ($1, $2, $3) 返回 "id" [["prd_item_id", 52], ["created_at ", 2017-11-12 14:02:09 UTC], ["更新 ated_at", 2017-11-12 14:02:09 UTC]]

Answer 1

你的问题是你这样做了：

permit(
  ..., 
  :prd_allisland_flat_deliveries_attributes,
  :prd_province_vise_deliveries_attributes
)

但是，您不允许 :prd_allisland_flat_deliveries 或 :prd_province_vise_deliveries。这就是您的参数中的内容。

因此，您会收到 Unpermitted parameters 错误。要么允许这些参数，要么修改你的部分以包含_attributes。

允许他们：

params.require(:prd_item).permit(
  :item_name, 
  :brand, 
  :item_no, 
  :short_description, 
  :long_description, 
  :prd_type_id, 
  :usr_vendor_property_id, 
  :price,:base_price, 
  :price_discount, 
  :percentage_discount, 
  :stock_count, 
  :availability, 
  :tags, 
  :remove_image, 
  :delivery_type , 
  :min_stock_count,
  prd_item_images_attributes: [:id, :image, :description, :link, :_destroy ],
  prd_temp_variation_stores_attributes: [:id, :product_variations, :variation_items, :_destroy],
  prd_temp_compound_stores_attributes:[:id,:compound, :compound_item, :_destroy],
  prd_temp_spec_stores_attributes:[:id,:compound, :compound_item, :_destroy],
  prd_allisland_flat_deliveries: [:id,:delivery_period,:delivery_rate],
  prd_province_vise_deliveries: [:id , :province_name , :delivery_rate, :delivery_period]
)
