Sending email using EmailMultiAlternatives where from_email contains comma

[Erol Merdanović]

Hi all

I'm using EmailMultiAlternatives to send email. I defined from_email as

Mike  


and it works great. But, if I try to send with

Mike, CEO 


I get an error that Mike is not valid email. How to correctly send email 
which contains comma in sender?

Integrating RabbitMQ with Django

[Erol Merdanović]

Hi all

I'm using Django to develop a service. Service connects to RabbitMQ and 
receives events that are translated to creating/updating/deleting of the 
database records. 

What is the best way to run RabbitMQ consumer with Django? I'm using Pika 
library and I run consumer as a management command (python manage.py 
listen_to_changes). Is this a good solution? I don't see it so. I'm running 
Django as WSGI so I presume there are no start/stop Django events that I 
could plugin in to start/stop consumer.

I'm aware of the Celery and how it nicely integrates into Django, but for 
me it's not an option.

What do you suggest? How to run RabbitMQ with Django (stability is the main 
objective).

Re: Integrating RabbitMQ with Django

[Erol Merdanović]

Hello Vijay

The differences are
1. Celery message and our message has different format
2. Celery uses custom queues

Is this correct?

Re: Integrating RabbitMQ with Django

[Erol Merdanović]

@Vijay

Yes, source of the messages is outside of the Django application. I could 
use some transformers, but again, it's extra moving part.

@Sadaf

Ok, thank you for the blog. I will check it out. But again, Celery is great 
but I'm not really sure it solves my problem.

Re: Integrating RabbitMQ with Django

@Tom

Yes, it was also thinking about using supervisord. But I'm interested if 
there is anything else that nicely integrates into Django.

@Felipe

Yes, I'm using pika. Afaik there are no decent tutorials how to implement 
consumers into Django.

Re: Integrating RabbitMQ with Django

@Felipe

Yes, I use very similar approach. Thank you for the example.

I found a great project https://github.com/rfk/django-supervisor that 
enables me to run Django commands under supervisor. I will test it and let 
you know how it goes.
