When my company migrated from MM2 to MM3, they discovered there were things
that didn't work as expected (don't get me started). So they developed a set of
Python functions which allowed then to fill in the missing functionality.
However, they've discovered that some of those functions either never worked
properly, or no longer work. For example,
```
def list_nonmembers(mlist):
for accepted in mlist.accept_these_nonmembers:
print("Accepted: ",accepted)
for held in mlist.hold_these_nonmembers:
print("Held: ",held)
```
They're run by shelling into the machine which hosts mailman and executed like
so (where scripts is `scripts.py`)
```
sudo -iu mailman mailman shell -l MAILING_LIST_ID --run scripts.list_nonmembers
```
That should work. What happens when you run it? Possibly it prints
nothing because the list's accept_these_nonmembers and
hold_these_nonmembers attributes are empty.
I'm recommending that we install Postorius, as I suspect many of the functions
they've written are already present in that UI, but it's not as simple as that.
Instead they're wanting a handful of these functions (including the one listed
above) replaced sooner than we could get Postorius up and running.
I've gotten this far:
```
from mailman.interfaces.listmanager import IListManager
from zope.component import getUtility
mylist_id = 'bravo-op...@tena-sda.org'
list_manager = getUtility(IListManager)
mylist = list_manager.get(mylist_id)
```
The mylist variable is of type `mailman.model.mailinglist.MailingList`, and
includes an Attributes for nonmembers:
```
mylist.nonmembers
<mailman.model.roster.NonmemberRoster object at 0x7ffffa3e65b0>
```
But this nonmembers property doesn't output any users/addresses when printed,
and throws a TypeError when I try to iterate over it:
First of all I think there may be some confusion between the list's
nonmembers and the *_these_nonmembers attributes. *_these_nonmembers are
legacy attributes which exist to support `^...` regexps and `@list_id`
entries, but the preferred way to accept, hold, reject or discard
individual nonmembers is to set the nonmember's moderation action.
```
Traceback (most recent call last):
File "<console>", line 1, in <module>
TypeError: 'NonmemberRoster' object is not iterable
```
You need to iterate over mylist.nonmembers.members, i.e. the roster's
members, not the roster.
So, given a mailing list instance, retrieved via `list_manager.get(mylist_id)`,
how would I go about printing all nonmembers and their current roles in a list
(held, accepted, etc.)? Alternately, is there a different question I should be
asking in order to retrieve that information?
It's not roles as you've already limited the role to nonmember. It's
moderation_action.
```
for nonmember in mylist.nonmembers.members:
print(f'Nonmember: {nonmember.address.email},'
f' moderation_action: {nonmember.moderation_action}')
```
Note that moderation_action: None means list default.
