You can add an Activity object to the feed using the add or add_many instructions.
feed = UserPinFeed(13)
feed.add(activity)
# add many example
feed.add_many([activity])What's an activity
The activity object is best described using an example. For Pinterest for instance a common activity would look like this:
Thierry added an item to his board Surf Girls.
In terms of the activity object this would translate to:
Activity(
actor=13, # Thierry's user id
verb=1, # The id associated with the Pin verb
object=1, # The id of the newly created Pin object
target=1, # The id of the Surf Girls board
time=datetime.utcnow(), # The time the activity occured
)The names for these fields are based on the activity stream spec.
