ruby-on-rails – “表单提交”按钮仅在重新加载后才起作用

Ruby 前端之家
前端之家收集整理的这篇文章主要介绍了ruby-on-rails – “表单提交”按钮仅在重新加载后才起作用，前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。
我有一个建立表的索引页,我试图允许用户在表中编辑行.我试图以最基本的方式这样做 – 没有 javascript,ajax等,除非Rails提供它.

我的表在索引方法中显示正常,并且有一个表格作为表中的最后一行,可用于添加新行.新表格工作正常.每行都有一个编辑链接,路由到控制器的编辑方法.控制器设置要编辑的对象,并使用要编辑的行中的表单呈现索引.我的问题是这个表单不会提交,但如果我刷新页面,它将提交.

页面将在刷新后提交的事实非常混乱.我不会看到刷新会做什么不同,然后点击链接(它仍然应该通过相同的路由,相同的变量是正确的),我看不到在刷新之前和之后的形式的任何区别.有什么想法可能发生什么？

我不知道什么代码甚至开始寻找,但在这里;

index.html.erb

  1. ...
  2. <tbody>
  3.   <% @boms.each do |line| %>
  4.    <% if line == @bom %>
  5.      <%= render("form_in_table",form_objects: @bom,button_text: "Update") %>
  6.     <% else %>
  7.       <%= render("bom_in_table",line: line) %>
  8.     <% end %>
  9.   <% end %>
  10.   <% if @bom.new_record? %>
  11.     <%= render("form_in_table",form_objects: [@li,@bom],button_text: "Add") %>
  12.   <% end %>
  13. </tbody>
  14. ...

_form_in_table.html.erb

  1. <%= form_for(form_objects,html: {class: "form-in-table"}) do |f| %>
  2.   <tr>
  3.     <td><%= f.text_field :quantity %></td>
  4.     <td colspan="2">
  5.       <%= f.select(:part_id,options_from_collection_for_select(@parts,:id,:pricebook_name),prompt: "Select a Part",) %></td>
  6.     <td></td>
  7.     <td></td>
  8.     <td></td>
  9.     <td><%= f.submit(button_text,class: "btn btn-primary btn-mini") %></td>
  10.   </tr>
  11. <% end %>

_bom_in_table.html.erb

  1. <tr>
  2.   <td><%= line.quantity%></td>
  3.   <td><%= line.part_number %></td>
  4.   <td><%= line.part_description %></td>
  5.   <td><%= number_to_currency(line.part_cost) %></td>
  6.   <td><%= line.part_unit %></td>
  7.   <td><%= number_to_currency(line.extension) %></td>
  8.   <td><%= link_to('Edit',edit_bom_path(line)) %></td>
  9. </tr>

boms_controller.rb

  1. ...
  2. def edit
  3.   @bom = Bom.find(params[:id])
  4.   @li = @bom.line_item
  5.   @boms = @li.boms.sorted_by_part_number
  6.   @parts = Part.sorted_by_number
  7.   render 'index'
  8. end
  9. ...

如果这对解密代码/意图很有用,我有一些line_items,part和boms的集合; line_item有很多boms,而line_item有很多部分通过boms.除了零件/订单项关系外,bom有一个数量. BOM是材料清单的缩写. @li是被操纵的line_item.我遇到的形式是查看/添加/编辑属于订单项的bom(数量和部分)的集合.
