Hi I am using the follwoing 2 functions to create and send a pdf via mail on the fly. What Am I doing wrong. (The export pdf function works properly when showing it in the browser.)
The error I am getting is "TypeError: 'ContentFile' object does not support indexing". What I am doing wrong? Almost all of this code has been taken from some blogs, so I dont know how it exactly works. But if you dont understand some things please comment. I will reply.
if request.method=="POST":
form = ReportSendMailForm(request.POST)
if form.is_valid():
email = form.cleaned_data['mail']
message = form.cleaned_data['message']
print email
print message
result = export_pdf(request,id)
file_to_be_sent= ContentFile(result)
#print file_to_be_sent
if result:
#try :
subject, from_email, to = request.user.username+' has sent a report for review',' Dtz Team', email
html_content = render_to_string('email/report.html',{'username':request.user,'messgae':message})
msg = EmailMultiAlternatives(subject,'', from_email, [to])
msg.attach_alternative(html_content, "text/html")
msg.attach("Report.pdf", file_to_be_sent, "application/pdf")
msg.send()
messages.success(request,'Please check your email id '+email+' for further instructions.')
return HttpResponse('success')
#except:
# pass
messages.error(request,'Error occured in the pdf.')
return HttpResponse(status=410)
