Question

我有一个显示日期和时间的表单，例如

它的代码如下：

 <%= f.fields_for :availabilities do |ff| %>
<% ["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"].each do |day| %>
    <div class="row">
      <div class="col-md-4">
        <div class="ck-button">
          <label>
            <%= ff.check_box "day", {multiple: true, checked: @therapist.available_times.key?(day)}, day, false %>
            <span><%= day %></span>
          </label>
        </div>
      </div>
      <div class="col-md-4">
        <div class="answer">
          <%= ff.select "start_time", ["1 AM", "2 AM", "3 AM", "4 AM", "5 AM", "6 AM", "7 AM", "8 AM", "9 AM", "10 AM", "11 AM", "12 PM", "1 PM", "2 PM", "3 PM", "4 PM", "5 PM", "6 PM", "7 PM", "8 PM", "9 PM", "10 PM", "11 PM"], {:selected => (@therapist.available_times.key?(day) ? @therapist.available_times[day][:start] : '7' )} %>
        </div>
      </div>
      <div class="col-md-4">
        <div class="answer">
          <%= ff.select "end_time", ["1 AM", "2 AM", "3 AM", "4 AM", "5 AM", "6 AM", "7 AM", "8 AM", "9 AM", "10 AM", "11 AM", "12 PM", "1 PM", "2 PM", "3 PM", "4 PM", "5 PM", "6 PM", "7 PM", "8 PM", "9 PM", "10 PM", "11 PM"], {:selected => (@therapist.available_times.key?(day) ? @therapist.available_times[day][:end] : '17' )} %>
        </div>
      </div>
    </div>
  <% end %>

但是，当我提交此消息时，发送到我的控制器的数据如下：

"availabilities"=>{"start_time"=>"1 AM", "end_time"=>"1 AM", "day"=>["Monday", "Tuesday", "Wednesday", "Thursday", "Friday"]}

我真正想要得到的是：

"availabilities"=>[{"start_time"=> "1 AM", "end_time"=>"1 AM", "day" => "Monday"},{"start_time"=> ...},...]

仅适用于所选日期。

从管制员的角度看，我的许可证如下：

:availabilities => [:day, :start_time, :end_time],

编辑：我将multiple更改为false，现在可用性具有我想要的形式，但是我只得到了最后一个检查项，而不是所有检查字段及其相关时间的数组

Answer 1

您必须按某种方式对字段名称进行分组。试试这个：

首先，使用each_with_index进行一些索引以将它们分组：

["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"].each_with_indexx do |day, idx|

现在您可以编写如下内容：

<%= ff.check_box "availabilities[#{idx}][day]", .... %>
<%= ff.select "availabilitlies[#{idx}][start_time]", .... %>
<%= ff.select "availabilitlies[#{idx}][end_time]", .... %>

参数将有所不同，而不是对象数组：

availabilities => {'0' => {'day' => 'Sunday', "start_time" => .., "end_time" => ...}, '1' => {'day' => 'Monday', .... }}

尝试以下代码：

  <%= f.fields_for :availabilities do |ff| %>     
  <div class="row">
  <div class="col-md-4">
    <div class="ck-button">
      <label>
      <% days = ['Mon', 'Tue', 'Wen', 'Thu', 'Fri', 'Sat', 'Sun'] %>
      <% days.map do |day| %>          
      <%= ff.check_box :count,{multiple: false},day,nil %>
      <%= ff.label day %>
      <%end%>
      </label>
    </div>
  </div>
  <div class="col-md-4">
    <div class="answer">
      <%= ff.select "start_time", ["1 AM", "2 AM", "3 AM", "4 AM", "5 AM", "6 AM", "7 AM", "8 AM", "9 AM", "10 AM", "11 AM", "12 PM", "1 PM", "2 PM", "3 PM", "4 PM", "5 PM", "6 PM", "7 PM", "8 PM", "9 PM", "10 PM", "11 PM"], {:selected => (@therapist.available_times.key?(day) ? @therapist.available_times[day][:start] : '7' )} %>
    </div>
  </div>
  <div class="col-md-4">
    <div class="answer">
      <%= ff.select "end_time", ["1 AM", "2 AM", "3 AM", "4 AM", "5 AM", "6 AM", "7 AM", "8 AM", "9 AM", "10 AM", "11 AM", "12 PM", "1 PM", "2 PM", "3 PM", "4 PM", "5 PM", "6 PM", "7 PM", "8 PM", "9 PM", "10 PM", "11 PM"], {:selected => (@therapist.available_times.key?(day) ? @therapist.available_times[day][:end] : '17' )} %>
    </div>
  </div>
</div>  <% end %>
