Hi
I'd like to use it in a forms.py to retrieve users own photos to
attach to a blogpost. So actually this would do the job
def __init__(self, *args, **kwargs):
self.user = kwargs.pop('user')
super(forms.Form, self).__init__(*args, **kwargs)
self.fields['url'].queryset = Image.objects.filter(member=self.user)
But I run into a a keyerror because of the pop() function
http://dpaste.com/146191/
Where can i find more information about the pop() function because
it's not really clear to me. Found so far
http://docs.python.org/tutorial/datastructures.html
but it still remains unclear to me.
This is the queryset which works in the view Image.objects.filter
(member=request.user)
Thanks guys
