django：附pisa生成pdf到电子邮件

我想弄清楚如何得到由比萨生成的PDF附加到电子邮件。早些时候，我能够使用缓冲区来创建附件，但是那时我正在使用直接的reportlab。我无法弄清楚如何将这一概念应用到转换的PDFdjango：附pisa生成pdf到电子邮件

这是你将如何使用简单的ReportLab做到这一点：

def pdfgenerate(request): 
    # Create the HttpResponse object with the appropriate PDF headers. 
    response = HttpResponse(content_type='application/pdf') 
    response['Content-Disposition'] = 'filename="invoicex.pdf"' 

    buffer = BytesIO() 

    # Create the PDF object, using the BytesIO object as its "file." 
    p = canvas.Canvas(buffer) 

    # Draw things on the PDF. Here's where the PDF generation happens. 
    # See the ReportLab documentation for the full list of functionality. 
    p.drawString(100, 100, "Hello world.") 

    # Close the PDF object cleanly. 
    p.showPage() 
    p.save() 

    # Get the value of the BytesIO buffer and write it to the response. 
    pdf = buffer.getvalue() 
    buffer.close() 

    email = EmailMessage('Hello', 'Body', '[email protected]', ['[email protected]']) 
    email.attach('invoicex.pdf', pdf , 'application/pdf') 
    email.send() 
    return HttpResponseRedirect(request.META.get('HTTP_REFERER'))

这是我到目前为止的代码，使用，一个比萨生成的PDF：

def render_to_pdf(request, 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")), result) 
    if not pdf.err: 
     response = HttpResponse(result.getvalue(), mimetype='application/pdf') 
     response['Content-Disposition'] = 'filename="invoicex.pdf"' 
     email = EmailMessage('Hello', 'Body', '[email protected]', ['[email protected]']) 
     email.attach('invoicex.pdf', pdf , 'application/pdf') 
     email.send() 
     return HttpResponseRedirect(request.META.get('HTTP_REFERER')) 
    return HttpResponse('We had some errors<pre>%s</pre>' % escape(html)) 

def labelsend(request, order_id): 
    labels = LabelOrder.objects.get(LabelOrderID=order_id) 
    args = {} 

    args['labels'] =labels 

    return render_to_pdf(request, 'labelsforprint.html', args)

你需要result.getvalue（）不PDF

email.attach('invoicex.pdf', result.getvalue() , 'application/pdf')
