使用新操作错误中的嵌套资源为用户创建各种记录

Question

我有一个模型

User

和

StockShipment

。

我正在尝试通过 StockShipment

new

操作为我的用户创建各种 StockShipment。

为此，我在我的用户模型中使用：

accepts_nested_attributes_for :stock_shipments, reject_if: :all_blank, allow_destroy: true

在我的stockshipments/new.html.erb

<%= form_with model:  [@user, @stock_shipment] do |form| %>
             <%= form.fields_for :stock_shipments, @user.stock_shipments.build do |shipment_form| %>
                <%= render 'shared/shipment_fields', form: shipment_form, locals: { user: current_user, user_stock: @user_stock } %>
              <% end %>

在我的库存发货控制器中：

  def new
    @user = current_user
    @stock_shipment = StockShipment.new
    @user.stock_shipments.build 
  end

  def create
    @user = current_user
    @user_stock = UserStock.find(params[:stock_shipment][:user_stock_id])
    @stock_shipment = @user.stock_shipments.build(stock_shipments_params)

    if @stock_shipment.save
      ShipmentNotificationMailer.new_shipment_notification(@stock_shipment).deliver_later
      redirect_to user_stock_shipments_path(current_user), status: :see_other
    else
      puts @stock_shipment.errors.full_messages.inspect
    end
  end

最后，我有强大的参数来接受嵌套属性：

def stock_shipments_params
  params.require(:stock_shipment).permit(
    :country, :phone, :email,
    :name, :quantity, :address, :city, :province, :postalcode, :surname, :user_id, :campaign_id, :gift_selection_id, :delivery_date, :stock_variation, :description, :user_stock_id,
    stock_shipments_attributes: [:id, :country, :phone, :email, :name, :quantity, :address, :city, :province, :postalcode, :surname, :user_id, :campaign_id, :gift_selection_id, :delivery_date, :stock_variation, :description, :user_stock_id, :_destroy]
  )
end

我一直收到以下错误：

Unpermitted parameter: :stock_shipments.

我的参数正在传递：

Answer 1

您没有显示部分内容，这是一些问题所在的地方，但是您将

user_stock: @user_stock

发送到其中，但

@user_stock

尚未在任何地方定义。

大多数情况下，您的

form_with

和

fields_for

通话中都会有很多不必要的垃圾。您应该遵循嵌套表单指南以获得乐趣和利润。
