帶有復選框的searchlogic

Question

我正在使用searchlogic對我的結果集執行搜索。

下面是我的搜索表，其中包含復選框。

<% 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 %>

只要選中復選框，以上代碼就可以正常工作，但是如果所有復選框均為空，則不返回所有行，而不返回任何行。

在我的地址欄中，顯示以下參數：

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

如果未選中任何復選框，則傳遞0。

如果未選擇任何內容，如何返回所有行？

好的，找到解決方案。 您需要為unchecked_value傳遞“ 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 %> 

希望這可以對其他人有所幫助
