"MANAGERS" setting doesn't correctly process the value, if it is given as described in the documentation

[angry.kustomer@…]

Django 1.6.5
According to the docs (​https://docs.djangoproject.com/en/1.6/ref/settings/#managers) MANAGERS expects a tuple
of the same format as for ADMINS, that is tuple of tuples.
In the practice it crashes with an error:

PATH_TO_MY_VIRTUAL_ENV/lib/python3.4/site-packages/django/core/mail/message.py", line 244, in message

msgTo = self.extra_headers.get('To', ', '.join(self.to))

TypeError: sequence item 0: expected str instance, tuple found

That is system currently expects it to be a tuple of strings, not other tuples. If given so, everything works fine.

Hi,

What code is triggering this error (can you also provide the full traceback)?

Using the example from the documentation, I can't reproduce your error (I tried on master and on 1.6):

# settings.py
ADMINS = (('John', 'john@example.com'), ('Mary', 'mary@example.com'))
MANAGERS = ADMINS

# test.py
from django.core.mail import mail_managers, mail_admins
mail_managers('test', 'test')
mail_admins('test', 'test')

I'm closing this as worksforme. Can you please reopen with the full traceback?

Thanks.

My bad, sorry. Looks like a minor difference in function parameters.
I'm using send_mail() and it expects list of strings, it cannot just take MANAGERS instead.
Thank you.
