Sorry for the vague description, but i find it hard to exactly name
the problem i am facing. Hopefully my description is clear enough:
I am working on a reporting app that collects and displays events/
actions that happened in my application.
I wrote a litte plugin base class and added plugins for all of the
relevant events i am interested in.
Basically a plugin only defines the query that is used to return the
matching events.
Now i am facing the situation that the queries are only evaluated
once:
A view that instantiates all my plugins and collects their events
(get_plugin_data) always returns the same data unless i restart my
server.
class DigestPluginBase(object):
def get_plugin_data(self):
if self.queryset:
data = list(self.queryset)
else:
data = []
return data
class UpdatesNew(DigestPluginBase):
queryset = Update.objects.filter(timestamp__gte=yesterday)
Querysets are lazy, so i assume this is a problem with the way i
assign/define the queryset for my plugin.
But then i don't see how the old data is stored in my class as the
there should be a new instance (and new queries) of my class every
time the view is called.
So where do i go wrong?
On a side note: Can you think of more elegant ways to define the
querysets for my plugins?
