[英]Can't use search feature in datatables server-side processing with django-datatables-view
I want to implement datatables with server-side processing because I have a lot of data to present in a single page(simple datatables are taking a lot of time).I went through the documentation in django-datatables-view 我想通过服务器端处理来实现数据表,因为我在一个页面中要呈现大量数据(简单的数据表会花费很多时间)。我浏览了django-datatables-view中的文档
I tried to implement it in my project,I can now successfully retrieve data from the server side but cannot use ' search ' feature. 我尝试在项目中实现它,现在可以从服务器端成功检索数据,但不能使用“ 搜索 ”功能。
If I type some thing in searchbox,it showing processing for a while but not updating the list of data displayed in the tables. 如果在搜索框中键入某些内容,它将显示一段时间的处理过程,但不会更新表中显示的数据列表。
I used python 3.6.5 and Django 2.0.6 我使用python 3.6.5和Django 2.0.6
Below is the code which I used: 下面是我使用的代码:
html : html:
<link rel="stylesheet" type="text/css" href="https://cdn.datatables.net/1.10.19/css/jquery.dataTables.min.css">
<script src="https://cdn.datatables.net/1.10.19/js/jquery.dataTables.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
var a = $('#tl').dataTable( {
"bPaginate": true,
"bProcessing": true,
"bServerSide": true,
"sAjaxSource": "{% url 'order_list_json' %}"
});
});

def filter_queryset(self, qs):
search = self.request.GET.get(u'search[value]', None)
if search:
qs = qs.filter(name__istartswith=search)
return qs
can anyone please help me to implement the search feature? 谁能帮我实现搜索功能?
I think your error is here: 我认为您的错误在这里:
qs = qs.filter(name__istartswith=search)
name
should be the name of the column you want to search : name
应该是您要搜索的列的名称:
['barcode', 'volret', 'state', 'flags', 'capacity','typefull','ip']
