Question

我正在创建一个设备，我在我的设备控制器中有两个动作，new和create ..我有两个视图，它们是新视图和部分视图。

我还有四个表.. equipments，equipment_types，equipment_locations和equipment_management_informations ..

表单看起来像..

>= error_messages_for 'equipment'
%table.contentText{:style => "width: 100%"}
  - if @types
    %tr
      %td Equipment Type
      %td= collection_select 'equipment', 'equipment_type_id', @types,  :id, :name, {}, :class => "dropdownSelect"
  %tr
    %td Location
    %td= select 'equipment', 'equipment_location_id', @equipment_locations.collect { |e| ["#{e.name.capitalize!}", e.id]},{}, :class => "dropdownSelect"
  %tr
    %td Serial Number
    %td= text_field 'equipment', 'serial_number', :class => 'textFields'
  %tr
    %td MAC Address
    %td= text_field 'equipment', 'mac_address', :class => 'textFields'
  %tr
    %td IP Address
    %td= text_field 'equipment', 'ip_address', :class => 'textFields'
  - if @stands
    %tr
      %td Stand
      %td= collection_select 'equipment', 'stand_id', @stands, :id, :street_no, :include_blank => true
  %tr
    %td{:valign => 'top'} Description
    %td= text_area 'equipment', 'description', :cols => 45, :rows => '3', :class => "txt_area_effect"

我的新观点如下：

> %h3 New equipment
%div{:style => "border: 1px solid #CCC;"}
  - form_tag :action => 'create', :estate_id => @estate do
    = render :partial => 'form'
    = submit_tag "Create"
    - action = "list"
    %input{:type => "button", :value => "Back", :onclick => "window.location='#{action}';", :class => "start"}

我的创建动作在我检查时显示为零

   @equipment = Equipment.find(params[:equipment])

它会出现类似

的错误

 Unknown key(s): equipment_type_id, mac_address, description, equipment_location_id, serial_number, ip_address

Answer 1

@equipment = Equipment.find(params[:equipment])

应该是：

@equipment = Equipment.new(params[:equipment])

或

@equipment = Equipment.new(params[:equipment])

（只是发表评论的回答，所以这停止显示为未答复）
