[Django]-Attach generated CSV file to email and send with Django

✅

Is there a particular reason you’re using an additional function at all? Just build your csv in memory – you can’t avoid that if you’re attaching it to email – and send that.

assigned_leads = lead.objects.filter(assigned_to__in=usercompany).distinct()
csvfile = StringIO.StringIO()
csvwriter = csv.writer(csvfile)
for leads in assigned_leads:
    csvwriter.writerow([leads.business_name, leads.first_name, leads.last_name, leads.email, leads.phone_number,leads.address, leads.city, leads.state, leads.zipcode, leads.submission_date, leads.time_frame, leads.comments])
message = EmailMessage("Hello","Your Leads","myemail@gmail.com",["myemail@gmail.com"])
message.attach('invoice.csv', csvfile.getvalue(), 'text/csv')

Python 3 and DictWriter example:

import csv
from io import StringIO
from django.core.mail import EmailMessage

rows = [{'col1': 'value1', 'col2': 'value2'}]
csvfile = StringIO()
fieldnames = list(rows[0].keys())

writer = csv.DictWriter(csvfile, fieldnames=fieldnames)
writer.writeheader()
writer.writerows(rows)

email = EmailMessage(
        'Subject',
        'Body',
        'from@email.com',
        ['to@email.com'],
    )
email.attach('file.csv', csvfile.getvalue(), 'text/csv')
email.send()

Neither are working :(

Approach 1:
        msg = EmailMultiAlternatives(subject, body, from_email, [to])
        msg.attach_alternative(file_content, "text/html")
        msg.content_subtype = 'html'
        msg.send()

Approach 2: 
        # email = EmailMessage(
        #     'Report Subject',
        #     "body",
        #     'xx@yy.com',
        #     ['zz@uu.com'],
        #     connection=connection,
        # )
        # email.attach('Report.html', body, 'text/html')
        # email.send()
