我正在搜索index.html.erb，它给了我一个错误。这是我的index.html.erb：

<% provide(:title, 'All configurations') %>
<h1>All configurations</h1>

<%= form_tag conf_show_all_path, :method => 'get' do %>
  <%= hidden_field_tag :direction, params[:direction] %>
  <%= hidden_field_tag :sort, params[:sort] %>
  <p>
    <%= text_field_tag :search, params[:search] %>
    <%= submit_tag "Search", :name => nil %>
  </p>
<% end %>

<table class="pretty" border="1" cellpadding="10">  
  <tr>
    <th><%= sortable("machine_name",       "M.Name")       %></th>
    <th><%= sortable("machine_brand",      "M.Brand")      %></th>
    <th><%= sortable("machine_model",      "M.Model")      %></th>
    <th><%= sortable("control_unit_brand", "C.Unit Brand") %></th>
    <th><%= sortable("control_unit_model", "C.Unit Model") %></th>

    <th><%= sortable("tool_axis_y",        "Axis Y")       %></th>
    <th><%= sortable("tool_axis_z",        "Axis Z")       %></th>
    <th><%= sortable("rotary_axis_number", "R.Axis")       %></th>

  </tr>  

  <% for conf in @confs %>  
  <tr class="<%= cycle('oddrow', 'evenrow') -%>">
    <td><%= link_to conf.machine_name, conf %></td>
    <td><%= conf.machine_brand %></td>
    <td><%= conf.machine_model %></td>
    <td><%= conf.control_unit_brand %></td>
    <td><%= conf.control_unit_model %></td>

    <td><%= conf.linear_axis_number %></td>
    <td><%= conf.description %></td>
    <td><%= conf.developer.name unless conf.developer_id.blank? %></td>
    <td><%= conf.updated_at %></td>
  </tr>
  <% end %>
</table>
<%= will_paginate @confs %>

这是应用程序_helper.rb中的可排序方法：

def sortable(column, title = nil)  
    title ||= column.titleize
    css_class = (column == sort_column) ? "current #{sort_direction}" : nil
    direction = (column == sort_column && sort_direction == "asc") ? "desc" : "asc"  
    link_to title, params.merge(:sort => column, :direction => direction, :page => nil), {:class => css_class}
end

最后，这是一个错误：

ActiveRecord::StatementInvalid in Confs#index
SQLite3::SQLException: no such column: name: SELECT  "confs".* FROM "confs"  ORDER BY name asc LIMIT 10 OFFSET 0
Extracted source (around line #30)

第30行是这样的：

问题是什么？我如何解决它？

好的，在

conf.rb

中搜索应该

updated\u at LIKE？

而不是

updated\u at LIKE？或者“

这是一个语法错误。关于这个问题，我把

confs\u controller.rb

中的

排序列从…params[：sort]：“name”
改为…params[：sort]：“machine\u name”
@mehow，我当时觉得很困惑，以为这就是答案，我更新了我的答案，现在是真的，谢谢你的警告
ActiveRecord::StatementInvalid in Confs#index
