如何在 order_form 中修复 'wrong number of arguments (1 for 0)'

Question

我的应用程序在一个小时前运行良好，然后我向 'orders' table 添加了两列 :pick_up 和 :send，之后我得到了这个错误

wrong number of arguments (1 for 0)

虽然我不明白为什么会导致此错误。

这里是orders_controller.rb:

class OrdersController < ApplicationController

  include CurrentCart
  before_action :set_cart, only: [:new, :create]
  before_action :set_order, only: [:show, :edit, :destroy]

  def index
    @orders = Order.all? 
  end

  def new
    @images  = ["1.jpg", "2.jpg", "3.jpg", "4.jpg", "5.jpg"]
    @random_no = rand(5)
    @random_image = @images[@random_no]

    if @cart.product_items.empty?
      redirect_to root_url, notice: 'Your Cart is Empty'
      return

    end
    @order = Order.new
    @client_token = Braintree::ClientToken.generate
  end

  def create
    @order = Order.new(order_params)
    if @order.save
      charge
      if @result.success?
        @order.add_product_items_from_cart(@cart)
      Cart.destroy(session[:cart_id])
      session[:cart_id] = nil
      OrderNotifier.received(@order).deliver 
      redirect_to root_url, notice: 'Thank You for Your Order'
      else
        flash[:error] = 'Please Check Your Cart'
        redirect_to root_url, alert: @result.message
        @order.destroy
      end
    else
      @client_token = Braintree::ClientToken.generate
      render :new
    end
  end


  def show

  end


  def destroy
    @order.destroy
    redirect_to root_url, notice: 'Order deleted'
  end

  private

  def set_order
    @order = Order.find(params[:id])
  end

  def order_params
    params.require(:order).permit(:name, :email, :address, :city, :country, :pick_up, :send)
  end

  def charge
    @result = Braintree::Transaction.sale(
        amount: @cart.total_price_usd,
        payment_method_nonce: params[:payment_method_nonce] )
  end

end

这是 _form.html.erb 订单：

<%= form_for @order do |f| %>
  <%= render 'msg' %>

  <div class="container">
    <div class="col-md-10">
      <h3>Please Enter Your Details</h3>
    </div>


  <div class="form-group">
    <div class="col-md-10">
      <%= f.label :name %>
      <%= f.text_field :name, size: 40, class: 'form-control' %>
    </div>
  </div>  

  <div class="form-group">
    <div class="col-md-10">
      <%= f.label :email%>
      <%= f.email_field :email, size: 40, class: 'form-control' %>
    </div>
  </div>  

  <div class="form-group">
    <div class="col-md-10">
      <%= f.label :address %>
      <%= f.text_area :address, cols: 40, class: 'form-control' %>
    </div>
  </div>  

  <div class="form-group">
    <div class="col-md-10">
      <%= f.label :city %>
      <%= f.text_field :city, size: 40, class: 'form-control' %>
    </div>
  </div>  

  <div class="form-group">
    <div class="col-md-5">
      <%= f.label :country %>
      <%= f.country_select :country, { priority_countries: [ "IS", "US", "DE", "ES", "PT" ]}, { class: "form-control" }%>
    </div>


  </div>  


  <div class="form-group">

    <div id="payment-form"></div>

    <div class="col-md-10">
      <br>
      <%= f.submit 'Place Order', class: 'buttons' %>

    </div>
  </div>  

  </div>
<% end %>

这是schema.rb的顺序部分：

create_table "orders", force: :cascade do |t|
  t.string   "name"
  t.string   "email"
  t.text     "address"
  t.string   "city"
  t.string   "country"
  t.datetime "created_at",                 null: false
  t.datetime "updated_at",                 null: false
  t.boolean  "shipped",    default: false
  t.string   "pick_up"
  t.string   "send"
end

我担心 send 不是标识符的幸运名称，因为 send 方法。
