set transactional template for email send

[hanhaa]

Issue Summary

Using Python 2.7. Taken your example code which works OK. I now want to tell the email to use a transnational template. I am using Mail.template_id="6a7d6c49-4b23-4ad7-b3af-aaee938d9ca8" but I just get a standard text email.

Steps to Reproduce

1. Use standard code example
2. Create a transnational template with an image on it.
3. send test email

Any other information you want to share that is relevant to the issue being reported. Especially, why do you consider this to be a bug? What do you expect to happen instead?

Technical details:

• sendgrid-python Version: master (latest commit: [commit number])
• Python Version: 2.7

Hey @hanhaa

Sorry to hear you are having issues. Since you did not provide the code you are using I am going to guess as to what is happening. Since you are only getting a text/plain email I am guessing you are passing a text/plain section in your API call. Something like this:

from_email = Email("test@example.com")
subject = "I'm replacing the subject tag"
to_email = Email("test@example.com")
content = Content("text/plain", "Text")
mail = Mail(from_email, subject, to_email, content)
mail.template_id = "6a7d6c49-4b23-4ad7-b3af-aaee938d9ca8"

When using templates you want to do one of two options. The first is to not pass any content at all or, the second is to pass both html and plain text content. I hope this helps resolve your issue.

Hi, Thanks for the reply. I have the following test code: # using SendGrid's Python Library # https://github.com/sendgrid/sendgrid-python import sendgrid import os from sendgrid.helpers.mail import * sg = sendgrid.SendGridAPIClient(apikey='REDACTED') from_email = Email("support@hanhaamobile.com") to_email = Email("ian@ianmaciver.com") subject = "Sending with SendGrid is Fun" #content = Content("text/plain", "and easy to do anywhere, even with Python") content="" mail = Mail(from_email, subject, to_email,content) Mail.template_id="6a7d6c49-4b23-4ad7-b3af-aaee938d9ca8" response = sg.client.mail.send.post(request_body=mail.get()) print(response.status_code) print(response.body) print(response.headers) When I run this I get: Traceback (most recent call last): File "/Users/ianmaciver/Dropbox/Parceline/HH Mobile/Portal Code/testSendGrid.py", line 18, in <module> response = sg.client.mail.send.post(request_body=mail.get()) File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/python_http_client/client.py", line 227, in http_request return Response(self._make_request(opener, request)) File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/python_http_client/client.py", line 161, in _make_request raise exc BadRequestsError I have tried a number of combinations with no content or content="" but still get the same error. Just trying to get a basic piece of code working. Thanks Ian MacIver CEO Hanhaa Mobile Tel: +44 (0) 7778 266547

Here is an example that should work for you:

import sendgrid
import os
from sendgrid.helpers.mail import Email, Substitution, Mail, Personalization
from python_http_client import exceptions

sg = sendgrid.SendGridAPIClient(apikey='APIKEY')

personalization = Personalization()
personalization.add_to(Email("sendgridtesting@gmail.com"))
mail = Mail()
mail.from_email = Email("email@kylearoberts.org")
mail.subject = "I'm replacing the subject tag"
mail.add_personalization(personalization)
mail.template_id = "51e49da0-76af-4056-8c3e-ae369ce554a6"
personalization.add_substitution(Substitution("-name-", "Example User"))
personalization.add_substitution(Substitution("-city-", "Denver"))
try:
    response = sg.client.mail.send.post(request_body=mail.get())
except exceptions.BadRequestsError as e:
    print(e.body)
    exit()
print(response.status_code)
print(response.body)
print(response.headers)

@hanhaa to add to this, I think that your empty string is causing content to default to text/plain.
In @kylearoberts' example, he is only passing the template ID with no content object.
You have another option, where you can pass BOTH text/plain and text/html to the Mail object along with the template ID.

We hope this helps!
Thank you @kylearoberts for the help and code sample!
