xhtml2pdf - Creating a pdf and emailing as an attachment


I am trying to create a pdf of a template and then have it automatically send an email to the contractor with the created pdf as an attachment.

Emails: I am able to send basic email without any issues

Create PDF: I am able to create the pdf with out any issues.

The issue is trying to combine the two features. I am not sure if I have to have the pdf automatically save to a location on the server and then attach the pdf to an email or if I can create the pdf and then email out in the same code.

def vendorwopdf(request, *args, **kwargs):
    wonumb = kwargs.get('WorkOderNumb')
    email = None
    
    searchresult = WorkOrders.objects.get(WorkOderNumb=wonumb)
    
    template = get_template("workorders/workorderpdf.html")
    html = template.render({"searchresult":searchresult})
    result = io.BytesIO()
    pdf = pisa.CreatePDF(html, result)
    result.seek(0)
    result = result.read()
    pdf_content = base64.b64encode(result).decode()

    
    email = EmailMessage(
    "RE: Authorized Workorder " + wonumb ,
    "Greetings please find attached the approved workorder",
    "no-reply@example.ca",
    ["no-reply@example.ca"],
    )
    email.attach("workorder.pdf", pdf_content, "pdf")
    
    email.send()

    return render(request,'workorders/vendorwo.html',{"searchresult":searchresult})

This view will produce the working pdf but I can not attach to email.


def vendorwopdf(request, *args, **kwargs):
    wonumb = kwargs.get('WorkOderNumb')
    
    searchresult = WorkOrders.objects.get(WorkOderNumb=wonumb)
    
    template = get_template("workorders/workorderpdf.html")
    context = {'searchresult': searchresult}
    response = HttpResponse(content_type='application/pdf')
    #response['Content-Disposition'] = 'attachment; filename="workorder.pdf"'
    response['Content-Disposition'] = 'filename="workorder.pdf"'
    template = get_template(template_path)
    html = template.render(context)

   
    pisa_status = pisa.CreatePDF(
        html, dest=response)
    if pisa_status.err:
        return HttpResponse('We had some errors <pre>' + html + '</pre>')
    return response

Solution

  • You can do something like this to only send the attachment in the mail without saving it in any database.

    import io
    from django.template.loader import get_template
    from xhtml2pdf import pisa
    from django.core.mail import EmailMessage
    
    
    template = get_template("template.html")
    html = template.render({"context": context_data})
    result = io.BytesIO()
    pdf = pisa.CreatePDF(html, result)
    result.seek(0)
    result = result.read()
    pdf_content = base64.b64encode(result).decode()
    
    

    After that, you can attach the pdf file to your email:

    email = EmailMessage(
        subject,
        body,
        from_mail,
        to_mail,
        cc,
        bcc,
    )
    email.attach("pdf_name", pdf_content, "pdf")
    

    Notice the encoding at last, that is because the pdf content sent in as an attachment should be base64 encoded, or else it'll throw an error.
