Django-如何将 'autonumber' 列添加到视图创建的表中？
Django- how to add 'autonumber' column to tables created by view?
我有一个 Django 项目，其中我的一个 views 正在根据数据库中存储的信息显示许多 table。 view定义如下：
def pipeline(request):
...
tables = []
def make_table(detailed_status, projects, status_view=False, first_table=False):
...
table_context_map = {
Project.ds2: {'fields': [['date added',1], ['site visit date',1], ['initial exc VAT',1]]},
...
# Similar lines to populate the tables with data from the database
...
}
table_context = table_context_map[detailed_status]
...
table_context['fields'] = [['project name',1], ['town',1], ['postcode',1], ['contact name',1]] + table_context['fields']
table = render_to_string('.../....html', table_context)
...
return render(request, 'abc.html', context)
我想做的是，在由此 view 创建的每个 table 的列中，并在该列中为 'autonumber' 中的每一行插入一个 'autonumber' =41=]。 table 将根据数据库查询动态填充，每当 view 为 运行 并且网页已加载时，我只想对每个 [=41= 中的项目列表进行编号] 创建时。
我该怎么做？我认识 Python Django，因此非常感谢任何帮助或指导。

当前在网页中显示这些 table 的 HTML 部分如下所示：
<div class="content">
{% block tables %}
{% for table in tables %}
{# Only shows table headers on first table (css first of type on multisection thead) #}
{{table}}
{% endfor %}
{% endblock tables %}
</div>

传递到 render_to_string(...) 视图的文件的 HTML 具有以下结构：

可能 forloop.counter 就是您要找的。
只需像这样在您的模板中使用它：
<ul>
{% for data in data_list %}
<li>{{ forloop.counter }}</li>
{% endfor %}
</ul>
至于你的文件，希望我的修改能奏效（用你的用户名标记）：
{% load getters money_handling staticfiles utilities %}
{% if projects %}
<div class="table-container m-t-lg">
<table class="multisection pipeline left">
<tr class="sub-summary">

{% if total_i %}<th>Initial exc VAT: {{total_i|money:"£"}}</th>{% endif %}
{% if total_u %}<th>Latest exc VAT: {{total_u|money:"£"}}</th>{% else %}

{% endif %}
