Question

在我的网站上，我正在尝试输入员工的姓氏，以便向我显示员工已售出的相应手机。所以在终端我输入了

rails g controller showemployeesales employeenamein salesout

我编辑了我的控制器，route.rb，输入和输出文件。这是我的代码：

控制器：`

         class ShowemployeesalesController < ApplicationController
         def employeenamein
         end

         def salesout
         @employee_name = params[:employee_name_in]
         @r = Employee.find_by_last(@employee_name)
         @sale_list = @r ? @r.sales : nil
         @sale_list = Sale.all
         end
         end

输入文件：

  <h2>Please enter the name of the Employee for whom you want to show 
  sales</h2>

  <%= form_tag(showemployeesales_salesout_path, :controller 
  "showemployeesales", :action => "salesout", :method => "post")

<div class="field">
<%= label_tag :Employee_Name %><br />
<%= text_field_tag :employee_name_in %>
</div>

<div class="action">
    <%= submit_tag "Submit Employee Name" %>
</div>

<% end %>

输出文件：

  <center><h1>These are the sales for <%= @employee_name %></h1></center>

  <center><table width = 65% border = 1>
  <tr> <th> Phone Name </th><th> Phone ID Number </th>
   <% @sale_list.each do |m| %>


   <tr> <td> <%= m.mobile %> </td> <td> <%= m.employee %></td></tr>

    <% end %> </table> </center>

运行我的网站后，我收到一条错误消息：

  `undefined method `find_by_last' for #<Class:0x007f9d1e963170> Did you mean? 
   find_by_sql

当我导航到我的＆＃34; / showemployeesales / employeenamein＆＃34;

我收到错误消息：/home/ubuntu/workspace/app/views/showemployeesales/employeenamein.html.erb:3: syntax error, unexpected tSTRING_BEG, expecting ')' ...es_salesout_path, :controller "showemployeesales", :action =... ... ^ /home/ubuntu/workspace/app/views/showemployeesales/employeenamein.html.erb:3: syntax error, unexpected ',', expecting ')' ...controller "showemployeesales", :action => "salesout", :meth... ... ^ /home/ubuntu/workspace/app/views/showemployeesales/employeenamein.html.erb:3: syntax error, unexpected ',', expecting ')' ...esales", :action => "salesout", :method => "post") ... ^ /home/ubuntu/workspace/app/views/showemployeesales/employeenamein.html.erb:5: syntax error, unexpected '<', expecting keyword_end <div class="field"> ^ /home/ubuntu/workspace/app/views/showemployeesales/employeenamein.html.erb:6: syntax error, unexpected '<' <%= label_tag :Employee_Name );@output_buffer.safe_append='<br /> ^ /home/ubuntu/workspace/app/views/showemployeesales/employeenamein.html.erb:15: syntax error, unexpected keyword_ensure, expecting end-of-input

并突出显示此行<%= form_tag(showemployeesales_salesout_path, :controller "showemployeesales", :action => "salesout", :method => "post")

查询记录，如：git diff
