AttributeError: manager when testing example in docs

[sergani]

Hi, I'm using the example in the docs: from marrow.mailer import Mailer, Message

mailer = Mailer(dict(
        transport = dict(
                use = 'smtp',
                host = 'localhost')))
mailer.start()

message = Message(author="[email protected]", to="[email protected]")
message.subject = "Testing Marrow Mailer"
message.plain = "This is a test."
mailer.send(message)

mailer.stop()

But getting the following traceback:

File "test_email.py", line 6, in <module>
    host = 'localhost')))
  File "/usr/lib/python2.6/site-packages/marrow/mailer/__init__.py", line 83, in __init__
    raise LookupError("Unable to determine manager from specification: %r" % (config.manager, ))
  File "/usr/lib/python2.6/site-packages/marrow/util/bunch.py", line 29, in __getattr__
    raise AttributeError(name)
AttributeError: manager

Any thoughts? I'm running python 2.6 and marrow.mailer:

[user@domain scripts]$ pip freeze | grep marrow
marrow.mailer==4.0.1
marrow.util==1.2.3

Hi, I updated my script to match the one in the project examples:

import                      logging
from marrow.mailer          import Message, Mailer
logging.basicConfig(level=logging.INFO)

mail = Mailer({
        'manager.use': 'futures',
        'transport.use': 'smtp',
        'transport.host': 'localhost',
        'transport.max_messages_per_connection': 5
    })
mail.start()

message = Message([('Alice Bevan-McGregor', '[email protected]')],
    [('Alice Two', '[email protected]')],
    "This is a test message.",
    plain="Testing!")

mail.send(message)
mail.stop()

But it still fails and throws:

Traceback (most recent call last):
  File "test_email.py", line 9, in <module>
    'transport.max_messages_per_connection': 5
  File "/usr/lib/python2.6/site-packages/marrow/mailer/__init__.py", line 83, in __init__
    raise LookupError("Unable to determine manager from specification: %r" % (config.manager, ))
LookupError: Unable to determine manager from specification: Bunch({'use': 'futures'})

Any thoughts?

Hello,

I came to the conclusion that Marrow Mailer doesn't work on Py2.6. Tested and working perfectly fine on Py2.7.

Thanks //M

Closing as ancient; futures-based managers require the backport of futures to function prior to Python 3.

Python 2 is dead and unsupported.
