When created, a message is in a pending state. It is not delivered to the recipient immediately. By default, some person must review its contents and must either accept or reject the message.
Moderation is done through the Admin site. To ease the action, a special message type is available: PendingMessage. It's nothing else but the classic Message type, but:
- It is intended to collect only messages in the pending state
- A dedicated simplified change view is available, with two main buttons: Accept and Reject
The moderator can give a reason in case of the rejection of the message. If provided, this piece of information will be reported in the notification to the sender.
You may automate the moderation by giving zero, one, or many auto-moderator functions to the views. The value of the parameter can be one single function or a sequence of functions as a tuple or a list.
Views supporting an
auto-moderators parameter are:
def mod1(message): # ... return None def mod2(message): # ... return None mod2.default_reason = 'mod2 default reason' urlpatterns = patterns('postman.views', # ... url(r'^write/(?:(?P<recipients>[^/#]+)/)?$', WriteView.as_view(auto_moderators=(mod1, mod2)), name='write'), url(r'^reply/(?P<message_id>[\d]+)/$', ReplyView.as_view(auto_moderators=mod1), name='reply'), # ... )
Each auto-moderator function will be called for the message to moderate, in the same order as the one set in the parameter.
message: a Message instance
The structure of the output is either a
rating or a tuple
rating may take the following values:
- 0 or
- 100 or
- an integer between 1 and 99
reason is a string, giving a specific reason for a rejection.
If not provided, a default reason will be taken from the
of the function, if any. Otherwise, there will be no reason.
The processing of the chain of auto-moderators is managed by these rules:
- If return is
Noneor outside the range 0..100, the auto-moderator is neutral
- If return is 0, no other function is processed, the message is rejected
- If return is 100, no other function is processed, the message is accepted
- Otherwise, the rating will count for an average among the full set of returned ratings
At the end of the loop, if the decision is not final, the sequence is:
- If there was no valid rating at all, then the
- An average rating is computed: if greater or equal to 50, the message is accepted.
- The message is rejected. The final reason is a comma separated collection of reasons coming from moderators having returned a rating lesser than 50.
