我正在使用Django 1.10.3和Reportlab将html导出为pdf现在我想通过电子邮件发送相同的pdf.I能够生成pdf但无法通过电子邮件发送。请帮助我实现它。
以下是我的观点：
def write_pdf_view(request):
response = HttpResponse(content_type='application/pdf')
response['Content-Disposition'] = 'inline; filename="mypdf.pdf"'
buff = StringIO()
menu_pdf = SimpleDocTemplate(buff, rightMargin=72,
leftMargin=72, topMargin=50, bottomMargin=18)
elements = []
styles = getSampleStyleSheet()
styles.add(ParagraphStyle(name='centered',fontName='Italic', alignment=TA_CENTER))
elements.append(Paragraph('A good thing about WeasyPrint is that you can convert a HTML document to a PDF. So you can create a regular Django template, print and format all the contents and then pass it to the WeasyPrint library to do the job of creating the pdf.', style=styles["Normal"]))
menu_pdf.build(elements)
response.write(buff.getvalue())
buff.close()
更新
subject = 'Welcome to Project Management Portal.'
message = 'Thank you for being part of us. \n We are glad to have you. \n Regards \n Team Project Management'
from_email = settings.EMAIL_HOST_USER
to_list = [request.user.email, settings.EMAIL_HOST_USER]
message = EmailMessage(subject, message, from_email, to_list)
pdf = open('mypdf.pdf', 'rb')
message.attach('mypdf-2.pdf', pdf, 'application/pdf')
message.send()

你试图直接使用send_email，你应该做的是构建一个EmailMessage对象，然后附加文件，并发送它。例如：
from django.core.mail import EmailMessage
message = EmailMessage(subject, body, from_email, to_list)
pdf = open('mypdf.pdf', 'rb')
message.attach('mypdf.pdf', pdf, 'application/pdf')
message.send()
当然，如果PDF在文件系统上，您也可以使用attach_file()而不是attach()。有关详细信息，请参阅文档的this section。

我发现解决方案我所要做的就是将pdf保存在项目中，然后使用SimpleDocTemplate完成，然后通过给出它的位置来附加相同的文件。 这是我做的：
视图：
def write_pdf_view(request):
doc = SimpleDocTemplate("media/mypdf.pdf", rightMargin=72, leftMargin=72, topMargin=-70)
styles = getSampleStyleSheet()
Story = [Spacer(1, 2 * inch)]
style = styles["Normal"]
paratext = ("A good thing about WeasyPrint is that you can convert a HTML document to a PDF. So you can create a regular Django template, print and format all the contents and then pass it to the WeasyPrint library to do the job of creating the pdf.")
p = Paragraph(paratext, style)
Story.append(p)
Story.append(Spacer(1, 0.2 * inch))
doc.build(Story)
subject = 'Welcome to Project Management Portal.'
message = 'Thank you for being part of us. \n We are glad to have you. \n Regards \n Team Project Management'
from_email = settings.EMAIL_HOST_USER
to_list = [request.user.email, settings.EMAIL_HOST_USER]
message = EmailMessage(subject, message, from_email, to_list)
message.attach_file('media/mypdf.pdf')
message.send()
messages.add_message(request, messages.INFO, 'The PDF is sent Successfully !!')
return redirect('home')

试试这个：
def pdf_view(request):
fs = FileSystemStorage()
filename = 'mypdf.pdf'
if fs.exists(filename):
with fs.open(filename) as pdf:
response = HttpResponse(pdf, content_type='application/pdf')
response['Content-Disposition'] = 'inline; filename="mypdf.pdf"'
subject = 'Welcome to Project Management Portal.'
message = 'Thank you for being part of us. \n We are glad to have you. \n Regards \n Team Project Management'
# message.attach = 'filename="mypdf.pdf", content_disposition="inline", data=open("mypdf.pdf", "rb")'
from_email = settings.EMAIL_HOST_USER
to_list = [request.user.email, settings.EMAIL_HOST_USER]
# send_mail(subject, message, message.attach, from_email, to_list)
message = EmailMessage(subject, message, from_email, to_list)
# pdf = open('media/mypdf.pdf', 'rb')
message.attach_file('media/mypdf.pdf')
message.send()
return response
else:
return HttpResponseNotFound('The requested pdf was not found in our server.')
