使用 Pisa 打印页码

Question

我在我的 django 项目中使用 pisa，以使我的 html 在 PDF 上生成以实现报告功能。我的一些报告变得相当大，我注意到它没有任何页码。有谁知道如何让页码显示在打印的 PDF 报告上？

这是我生成 PDF 的方式

if request.POST.has_key('print_report_submit'):
            context['show_report'] = True
            context['mb_logo'] = os.path.join(os.path.dirname(__file__), "../../../media/images/mb_logo.jpg")
            html = render_to_string('reports/fam_maturity_print.html', RequestContext(request,context))
            result = StringIO.StringIO()
            pdf = pisa.pisaDocument(StringIO.StringIO(html.encode("ISO-8859-1")), result)
            response = HttpResponse(result.getvalue(), mimetype='application/pdf')
            response['Content-Disposition'] = 'attachment; filename=family_maturity-statement.pdf'
            return response

HTML

{% if show_report %}

<table width="100%">

    <tr>
        <td colspan="2" align="center" width="400px">
            <h1 class="title">Family Maturities by Year</h1>

这个链接怎么说：

我遇到的一个问题是在我的页面中添加一个静态页脚，其中包含一个<pdf:pagenumber /> 标签，并且应该在生成的 PDF 的每一页底部显示当前页码。问题是，每个页面都只显示数字 0。解决方案非常简单，但我只能在研究 pisa 源代码后弄清楚：你只能在段落内使用标签，而不是（因为我做了）例如在一张桌子里面。即使表格内的段落也不起作用。它必须是顶级段落。

试试这个：

<div>
   <pdf:pagenumber />
</div>

Answer 2

这对我有用，您需要将其用于 A3 尺寸

@page{
        size: A3;
        margin: 1cm;

      @frame footer_frame {           /* Another static Frame */
        -pdf-frame-content: footer_content;
        left: 400pt; top: 1170pt; height: 20pt;
        
    }
    }

你必须放在上面的桌子上

<div id="footer_content"> Page <pdf:pagenumber>
of <pdf:pagecount> </div>
