python-3.x - pdf格式输出分散在django中

问题描述

您好我想使用创建发票WeasyPrint。我想得到格式良好的打印作为发票的输出。

我正在使用以下函数来创建 pdf：

from weasyprint import CSS, HTML

def render_to_pdf(context, file_name):
    file_data = render_to_string('order_detail.html', context)
    html = HTML(string=file_data).write_pdf(
        target='collections/%s' % (file_name),
        stylesheets = [CSS(string='body { font-size: 7px }')]
    )
    fs = FileSystemStorage("")
    with fs.open("collections/" + file_name) as pdf:
        response = HttpResponse(pdf, content_type="application/pdf")
        response['Content-Disposition'] = '"attachment; filename="%s"'% (file_name)
        print("pdf working")
        return response

在我使用的最新版本中，stringformat但之前我尝试使用普通的 jinja 模板并且输出是相同的。这是我的html：

{% load static %}
