python - Django-如何将 'autonumber' 列添加到 View 创建的表中？

Question

我有一个 Django 项目，其中我的一个 views 根据存储在数据库中的信息显示许多表。 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，在此 View 创建的每个表的一列中，并在该列中为表中的每一行插入一个“autonumber”。每当运行 view 并加载网页时，表格将根据数据库查询动态填充，我只想在创建每个表格时对项目列表进行编号。

我该怎么做？我熟悉 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表格的 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(...) View 的文件的 HTML 具有以下结构:

{% load getters money_handling staticfiles utilities %}

{% if projects %}
    <div class="table-container m-t-lg">

        <table class="multisection pipeline left">
            <tr class="sub-summary">
                <th colspan="4"><a href="?detailed_status={{detailed_status}}"><h3 class="p-l-sm">{{detailed_status_str}}</h3></a></th>

Answer 1

可能 forloop.counter正是您要找的。

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(用你的用户名标记它):

    {% load getters money_handling staticfiles utilities %}

{% if projects %}
    <div class="table-container m-t-lg">

        <table class="multisection pipeline left">
            <tr class="sub-summary">
                <th colspan="4"><a href="?detailed_status={{detailed_status}}"><h3 class="p-l-sm">{{detailed_status_str}}</h3></a></th>
                {% if total_i %}<th>Initial exc VAT: {{total_i|money:"£"}}</th>{% endif %}
                {% if total_u %}<th>Latest exc VAT: {{total_u|money:"£"}}</th>{% else %}
                <th></th>
                {% endif %}
            </tr>
        </table>
        <table class="multisection pipeline left m-b-xl">
            <tr class="summary">
                <th style="width: 3em;"></th>
                <th>Number</th> @someone2088 
                {% for field in fields %}
                    <th class="text-sm p-l-sm p-t-sm p-b-sm" style="width:{{widths|getval:forloop.counter0}}">
                    {% if field.1 %}
                        {% if sort == field.0 and not reverse %}
                            <a href="?sort=-{{field.0}}&detailed_status={{detailed_status}}">{{field.0}}</a>
                        {% else %}
                            <a href="?sort={{field.0}}&detailed_status={{detailed_status}}">{{field.0}}</a>
                        {% endif %}
