Form_tag不會將check_box_tag值添加到參數中

Question

我有Pieces模型，它是商店項目的部分。當我需要的時候，我會向用戶詢問，檢查棋子是否正常，或者是生成的表單。

我正在創建報告模型來存儲我向用戶詢問的表單。

所以，當我生成的形式check_box和text_field工作正常。但是當我提交表單時，我無法獲得check_box值作爲參數。

{"utf8"=>"✓", 
"_method"=>"patch", 
"authenticity_token"=>"5OmdXCDixwxru2yBtB3YmT3YF/ZqOByoAJ3J29TyJikxJdA+RXAvGjwu8MBIPlJCROFx4V7AUcA7IIqIgthD9g==", 
"notes"=>{"79"=>"asdasda","84"=>""}, 
"commit"=>"Submit", 
"id"=>"5"} 

這裏是我的edit.html.erb

<%- model_class = Report -%> 
<div class="page-header"> 
    <h1><%=t '.title', :default => [:'helpers.titles.edit', 'Edit %{model}'], :model => model_class.model_name.human.titleize %></h1> 
</div> 


    <% if @report.errors.any? %> 
    <div id="error_expl" class="panel panel-danger">

     <div class="panel-body">

    <% end %> 
    <table class="table table-striped">

     <th><%= model_class.human_attribute_name(:quantity) %></th> 
     </tr> 

    </thead> 
    <tbody> 
    <%= form_tag(report_path(@report), :method => :patch) do %> 

     <% @pieces.each do |piece| %> 
     <tr> 
       <td><div class="form-group"> 
    <%= check_box_tag(:status, name: "status["+piece.id.to_s+"]", class: 'form-control') %>

       <td><%= piece.item.name %></td> 
       <td><%= piece.item.brand %></td>

     </tr> 
     <tr>

       <%= text_field_tag(:note,"", placeholder: "Note ", name: "notes["+piece.id.to_s+"]",class: "form-control ") %> 
      </td> 
     </tr> 
     <% end %> 
    </tbody> 
    </table> 

     <div class="form-group"> 
     <div class="col-lg-offset-2 col-lg-10"> 
      <%= submit_tag("Submit",:class => 'btn btn-primary') %> 
      <%= link_to t('.cancel', :default => t("helpers.links.cancel")), reports_path, :class => 'btn btn-default' %>

     }else if(state == true){ 
     $("#hebele").addClass('hidden');

     } 
    }); 
</script> 

控制器：

def edit 
    @pieces = @report.pieces.joins(:item).group(:item_id) 
    @report = Report.find(params[:id]) 
end

您需要定義check_box_tag的價值：

<%= check_box_tag :status, piece.id, class: 'form-control' %>

如果你是一個editing@report，你會使用form_for最好：

<table> 
    <tbody> 
    <%= form_for @report do |f| %> 
     <% @pieces.each do |piece| %> 
     <tr> 
      <td> 
      <div class="form-group"> 
       <%= f.check_box :status, class: 'form-control', price.id %> 
      </div> 
      </td> 
      <td><%= piece.try(:serial_no) %></td> 
      <td><%= piece.item.category.name %></td> 
      <td><%= piece.item.name %></td> 
      <td><%= piece.item.brand %></td> 
      <td><%= piece.item.model %></td> 

      <% if piece.serial_no.start_with?("D") %> 
      <td><%= piece.item.pieces.count %> <%= piece.item.unit.name %></td> 
      <% else %> 
      <td><%= piece.item.pieces.sum(:quantity) %> <%= piece.item.unit.name %></td> 
      <% end %> 
     </tr> 
     <tr> 
      <td colspan=7 class="hidden" id="hebele"> 
      <%= f.text_field :note, placeholder: "Note", class: "form-control" %> 
      </td> 
     </tr> 
    <% end %> 
    <tr><td colspan="7"><%= f.submit, class: "btn btn-primary" %></td></tr> 
    <% end %> 
    </tbody> 
</table>
