Question

我的第一列中有一个带复选框的表，另一列中有一个计划名列表。我希望能够选中列表旁边的框，单击form_submit按钮，并将这些选中的列表另存为数据库中的列。

我使用数组列运行表 - 我可以手动将数组输入到列中（使用名为Adminium的数据库管理服务）。但是，只要我尝试通过应用程序更新数组值，它就会清除数组值并且不会添加所选项目。

查看

<%= form_tag :action => 'planselection', :id => @current_plan.id, :method => :put  do %>

<%= submit_tag "Add Selected Plans to Quote" %> 

 <table id="DT" class="table table-striped table-hover">
  <thead>
    <tr>
        <th></th>
            <th>Plan name</th>
      <th>Carrier</th>
      <th>Plan type</th>
      <th>Deductible</th>
      <th>Monthly Premium</th>
        <th></th>
    </tr>
  </thead>

  <tbody>
    <% @benefit_details.where(:plan_year => @current_plan.plan_year).each do |benefit_detail| %>

      <tr>
        <td><%= check_box_tag "plan_selection[]", benefit_detail.plan_name %></td>
        <td><%= benefit_detail.plan_name %></td> 
        <td><%= benefit_detail.carrier %></td>
        <td><%= benefit_detail.plan_type %></td>
                <td><%= benefit_detail.deductible %></td>
                <td><% @AgeTest = AgeFactor.where("carrier = ? AND age = ?", @Carrier, @Age).pluck(:age_factor) %></td>

                <td>
                        <a href="#" class="btn btn-circle btn-default btn-xs ">
                        <i class="fa fa-search"></i></a>
                        <a href="#" class="btn btn-circle btn-default btn-xs ">
                        <i class="fa fa-bar-chart-o"></i></a>
                        <a href="#" class="btn btn-circle btn-default btn-xs ">
                        <i class="icon-plus"></i></a>
                </td>


      </tr>
    <% end %>
  </tbody>
</table> 
<% end %>

控制器

  def planselection
    # TODO Add all plan selections to Current plan

    @current_plan.update(plan_selection: "plan_selection")
    #@current_plan.update("plan_selection=?", :planselection)

    redirect_to :back
  end

终端输出

Answer 1

试试这个 - ＆gt; @ current_plan.update（plan_selection：params [：plan_selection]）

Rails数组不保存到DB
