我正在尝试在使用reportlab生成的pdf中的表格后插入分页符,我正在使用以下函数生成pdf:

def render_to_pdf(template_src, context_dict):
template = get_template(template_src)
context = Context(context_dict)
html = template.render(context)
result = StringIO.StringIO()
pdf = pisa.pisaDocument(StringIO.StringIO(html.encode("ISO-8859-1")), dest=result, link_callback=fetch_resources)
if not pdf.err:
return result.getvalue()
return HttpResponse('We had some errors<pre>%s</pre>' % escape(html))
def fetch_resources(uri, rel):
return os.path.join(MEDIA_ROOT, uri.replace(MEDIA_URL, ""))

我以这种方式从 View 中调用该函数:
@login_required(login_url=reverse('accounts:login_box'))
def quote_pdf(request, quote_id):
data_pdf = {}
quote = get_object_or_404(Quote, id=quote_id)
data_pdf['pagesize'] = 'letter'
data_pdf['quote'] = quote
pdf = render_to_pdf('rents/quote_pdf.html', data_pdf)
return HttpResponse(pdf, mimetype='application/pdf')

这是我的模板(quote_pdf.html)
{% load humanize compress verbatim %}

我不知道如何在表格后插入分页符以在下一页中插入“条款和条件”。

我对pdf中的图像也有问题,渲染时没有人出现。

谢谢你帮助我

最佳答案

我找到了正确的方法,我需要在我的 pdf 中插入一些特定的样式

<style type="text/css">
@page {
size: {{ pagesize }};
margin: 1cm;
@frame footer {
-pdf-frame-content: footerContent;
bottom: 0cm;
margin-left: 0cm;
margin-right: 0cm;
height: 0cm;
}
}
.page-break{
page-break-after: always;
}
</style>

然后将具有 .page-break 类的元素放在您希望在 pdf 中设置分页符的位置。
