我正在构建一个市场应用程序。卖家可以列出要销售的产品。我使用best_in_place允许卖家在销售页面中输入跟踪号和运输公司名称。
我也将best_in_place用于另一个模型,并且工作正常。由于某种原因,订单表更新似乎不起作用。这些是我得到的错误:
NoMethodError in Orders#sales
undefined method `tracking' for nil:NilClass
错误指向第一行,下面使用了best_in_place。
以下是我的观点 - 显示了卖家列表和两列输入跟踪和运营商名称:
<div class="center">
<h2>Sales History for <%= current_user.name %></h2>
</div>
<% if user_signed_in? %>
<%= link_to 'Add New Listing', new_listing_path, class: "btn btn-link", data: { no_turbolink: true } %>
<% end %>
<table class="table table-striped table-bordered">
<tr>
<th class="col-md-2">Image</th>
<th class="col-md-2">Item</th>
<th class="col-md-1">Price</th>
<th class="col-md-2">Customer</th>
<th class="col-md-2">Date Sold</th>
<th class="col-md-2">Shipment Tracking #</th>
<th class="col-md-1">Carrier (UPS, USPS, etc.)</th>
</tr>
<% @orders.each do |order| %>
<tr>
<td><%= image_tag order.listing.image.url(:thumb) %></td>
<td><%= order.listing.name %></td>
<td><%= number_to_currency(order.listing.price) %></td>
<td><%= order.buyer.name %></td>
<td><%= order.created_at.strftime("%B %-d, %Y") %></td>
<td><%= best_in_place @order, :tracking, :type => :input %></td>
<td><%= best_in_place @order, :carrier, :type => :input %></td>
</tr>
<% end %>
</table>
这是我的控制器的销售方法和更新方法。
class OrdersController < ApplicationController
before_action :set_order, only: [:show, :edit, :update, :destroy]
before_action :authenticate_user!
before_action :check_user, only: [:edit, :update]
def sales
@orders = Order.all.where(seller: current_user).order("created_at DESC")
end
def update
@order = Order.find(params[:id])
@order.update_attributes(params[:order])
end
def check_user
if current_user.id != @seller && current_user.name != "admin admin"
redirect_to root_url, alert: "Sorry, you are not the seller of this listing"
end
end
答案 0 :(得分:0)
尝试拼写全部,看看它是否有效:
<%= best_in_place @order, :tracking, :type => :input, :path => {:controller => :sales, :action => :update, :id => order.id} %>
编辑:
我认为错误发生在each do
,请尝试以下内容:
<% @orders.each do |order| %>
<tr>
<td><%= image_tag order.listing.image.url(:thumb) %></td>
<td><%= order.listing.name %></td>
<td><%= number_to_currency(order.listing.price) %></td>
<td><%= order.buyer.name %></td>
<td><%= order.created_at.strftime("%B %-d, %Y") %></td>
<td><%= best_in_place order, :tracking, :type => :input %></td>
<td><%= best_in_place order, :carrier, :type => :input %></td>
</tr>
<% end %>
基本上我刚刚@order
交换了order
