Django模板打破DataTable
[英]Django template breaking DataTable
问题描述
I am trying to implement a basic DataTables table in my Django app. 
我正在尝试在我的Django应用程序中实现一个基本的DataTables表。 It only appears to fully render when my template variables are not included in the template: 当我的模板变量未包含在模板中时，它似乎只能完全渲染：
current_orders.html
{% load staticfiles %}
<!DOCTYPE html>
<html lang="en">
<head>
<!-- jQuery -->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<!-- DataTables.net -->
<link rel="stylesheet" href="{% static 'css/jquery.dataTables.min.css' %}">
<script src="{% static 'js/jquery.dataTables.min.js' %}"></script>
<script>
$(document).ready(function(){
$('#current_orders_table').DataTable();
});
</script>
<!-- Material Design Lite -->
<script src="https://storage.googleapis.com/code.getmdl.io/1.0.4/material.min.js"></script>
<link rel="stylesheet" href="https://storage.googleapis.com/code.getmdl.io/1.0.4/material.yellow-deep_purple.min.css" />
<link rel="stylesheet" href="https://fonts.googleapis.com/icon?family=Material+Icons">
</head>
<body>
<table id="current_orders_table" class="display mdl-data-table <mdl-js-data-table></mdl-js-data-table> mdl-shadow--2dp">
<thead>
<tr>
<th class="mdl-data-table__cell--non-numeric">Customer Name</th>
<th>Date order was placed via Email</th>
<th>Opportunity ID</th>
<th>BTMW Reference</th>
<th>Sales Order Number</th>
<th>Supplier PO Numbers</th>
<th>SAS Date of Delivery</th>
<th>Serial Numbers Recorded?</th>
<th>INCare Reference Number</th>
<th>Contract Start Date</th>
<th class="mdl-data-table__cell--non-numeric">INCare Notes</th>
<th class="mdl-data-table__cell--non-numeric">Ongoing Progress</th>
<th class="mdl-data-table__cell--non-numeric">Actual Status of Order</th>
<th>Status Updated</th>
<th>Invoice Raised</th>
<th>Invoice Notes</th>
</tr>
</thead>
<tbody>
{% for order in orders %}
<tr>
<td class="mdl-data-table__cell--non-numeric">{{ order.customer }}</td>
<td>{{ order.order_date }}</td>
<td>{{ order.op_ref }}</td>
<td>{{ order.btmw_ref }}</td>
<td>{{ order.sales_order_number }}</td>
<td>{{ order.supplier_po_numbers }}</td>
<td>{{ order.sas_date_of_delivery }}</td>
<td>{{ order.sas_notes }}</td>
<td>{{ order.serial_numbers_recorded }}</td>
<td>{{ order.incare_ref_number }}</td>
<td>{{ order.contract_start }}</td>
<td class="mdl-data-table__cell--non-numeric">{{ order.incare_notes }}</td>
<td class="mdl-data-table__cell--non-numeric">{{ order.ongoing_progress }}</td>
<td class="mdl-data-table__cell--non-numeric">{{ order.actual_status }}</td>
<td>{{ order.status_updated }}</td>
<td>{{ order.invoice_raised }}</td>
<td>{{ order.invoice_notes }}</td>
</tr>
{% endfor %}
</tbody>
</table>
</body>
</html>
views.py
def current_orders(request):
orders = get_list_or_404(Order, closed=False)
return render(request, 'tracker/current_orders.html',
{'orders': orders})
This will happily render a table, but without all the extra goodness; 这将很乐意呈现一张桌子，但没有额外的好处; search bar, pagination, sort arrows etc.. Yet when I remove the <tr> to </tr> lines from the <tbody> , those with {{ }} template variables, these elements render fine. 搜索栏，分页，排序箭头等。然而，当我从<tbody>移除<tr> to </tr> <tbody> ，那些带有{{ }}模板变量的行，这些元素渲染得很好。
From chrome DevTools I can see there is an error, but my JavaScript knowledge is minimal and it has me stumped. 从chrome DevTools我可以看到有一个错误，但我的JavaScript知识很少，而且让我感到难过。 Looking online this doesn't appear to be a common problem so my assumption is that I am missing something basic. 在网上看这似乎不是一个常见的问题所以我的假设是我缺少一些基本的东西。 Any help would be much appreciated. 任何帮助将非常感激。

您的标题只包含16列，但您的正文包含17.使列数匹配，否则DataTables会混淆并抛出错误。
