Question

我正在使用searchlogic对我的结果集进行搜索。

以下是我的搜索表单，其中包含复选框。

<% form_for @search do |f| %>
  <div class="searchbox" style="text-align: left; width: 100%">

    <span> Status: </span>

    Incomplete - <%=   f.check_box :sub_status_fk_equals_any, {:name => "search[sub_status_fk_equals_any][]"}, "51" %> 
    Complete - <%=   f.check_box :sub_status_fk_equals_any, {:name => "search[sub_status_fk_equals_any][]"}, "52" %> 
    Under Review - <%=   f.check_box :sub_status_fk_equals_any, {:name => "search[sub_status_fk_equals_any][]"}, "53" %> 
    Approved - <%=   f.check_box :sub_status_fk_equals_any, {:name => "search[sub_status_fk_equals_any][]"}, "54" %> 

    <%= f.submit "Submit"%>
  </div>
<% end %>

只要选中了复选框，但上面的代码工作正常，但如果所有复选框都为空，而不是返回所有行，则不会返回任何内容。

在我的地址栏中，会显示以下参数：

http://localhost/sub_test/?
search[order]=descend_by_sub_entry_date&
search[sub_status_fk_equals_any][]=0&
search[sub_status_fk_equals_any][]=0&
search[sub_status_fk_equals_any][]=0&
search[sub_status_fk_equals_any][]=0&
commit.x=15&commit.y=18&commit=Search

如果没有选中任何复选框，则传递0。

如果没有选择任何内容，如何返回所有行？

好的，找到了解决方案。您需要为unchecked_value

传递'nil'

Incomplete - <%=   f.check_box :sub_status_fk_equals_any, {:name => 
      "search[sub_status_fk_equals_any][]"}, "51", nil %> 

        Complete - <%=   f.check_box :sub_status_fk_equals_any, {:name => "search[sub_status_fk_equals_any][]"}, "52", nil %> 

        Under Review - <%=   f.check_box :sub_status_fk_equals_any, {:name => "search[sub_status_fk_equals_any][]"}, "53", nil %> 

        Approved - <%=   f.check_box :sub_status_fk_equals_any, {:name => "search[sub_status_fk_equals_any][]"}, "54", nil %>
