I am using Django 1.10.3 and Reportlab to export html to pdf now I want to email the same generated pdf.I was able to generate the pdf but unable to email it. Please help me achieve it.
Here is my view:
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()
Update:
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()

Try This:
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.')
You’re trying to just use send_email directly, and what you should be doing is building an EmailMessage object, and then attaching the file, and sending that. For example:
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()
Of course, if the PDF is on the filesystem, you might as well just use attach_file() instead of attach(). More info on that in this section of the docs.
I have found the solution all I had to do was to save the pdf in the project and I did it by using SimpleDocTemplate and then attached the same file by giving its location.
Here is what I did:
view:
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')
