Question

数据进入数据库，但它始终将：location提交为0.如何避免这种情况？我希望：location提交选中的值。

另外，使用simple_form而不是像这样做会更容易吗？

以下是部分内容：

<%= form_for(@offering) do |f| %>

    <%= render 'common/form_errors', object: @offering %>

    <%= f.label :description, "Description:" %> 

    <%= f.text_field :description %>


  <%= f.label :location, "Where?" %>

  <%= check_box("offering", :location, {}, "Alphabet City") %>Alphabet City
  <%= check_box("offering", :location, {}, "Battery Park") %>Battery Park
  <%= check_box("offering", :location, {}, "Chelsea") %>Chelsea
  <%= check_box("offering", :location, {}, "Chinatown") %>Chinatown

  <%= f.submit "Post your offering" %> 
  <% end %>

以下是它产生的HTML：

    <form accept-charset="UTF-8" action="/offerings" class="new_offering" id="new_offering" method="post"><div style="margin:0;padding:0;display:inline"><input name="utf8" type="hidden" value="✓"><input name="authenticity_token" type="hidden" value="L6oao6csQJ9TIRpEKG4BAzj3uH6FUMr9YmDYXx2HbFg="></div>



      <label for="offering_description">Description:</label> 

      <input id="offering_description" name="offering[description]" size="30" type="text">


      <label for="offering_location">Where?</label>

      <input name="offering[location]" type="hidden" value="0">

      <input id="offering_location" name="offering[location]" type="checkbox" value="Alphabet City">Alphabet City

      <input name="offering[location]" type="hidden" value="0">

      <input id="offering_location" name="offering[location]" type="checkbox" value="Battery Park">Battery Park

      <input name="offering[location]" type="hidden" value="0">

      <input id="offering_location" name="offering[location]" type="checkbox" value="Chelsea">Chelsea

      <input name="offering[location]" type="hidden" value="0">

      <input id="offering_location" name="offering[location]" type="checkbox" value="Chinatown">Chinatown


      <input name="commit" type="submit" value="Post your offering"> 
    </form>

所以我想通了。

隐藏的输入一些如何超越复选框。

所以我没有使用check_box，而是使用check_box_tag：

  <%= check_box_tag("offering[location]", "Alphabet City") %>Alphabet City
  <%= check_box_tag("offering[location]", "Battery Park") %>Battery Park
  <%= check_box_tag("offering[location]", "Chelsea") %>Chelsea
  <%= check_box_tag("offering[location]", "Chinatown") %>Chinatown

而不是：

  <%= check_box("offering", :location, {}, "Alphabet City") %>Alphabet City
  <%= check_box("offering", :location, {}, "Battery Park") %>Battery Park
  <%= check_box("offering", :location, {}, "Chelsea") %>Chelsea
  <%= check_box("offering", :location, {}, "Chinatown") %>Chinatown

check_box始终提交为0
