It is possible to limiting QuerySet in this kind of way:
creators_list = [\'jane\', \'tarzan\', \'chita\']
my_model.objects.filter(creator=creators_list)
Also if you're using sqlite and running into problems, there exists a limitation for the max number of items in the list.
def divideChunks(l, n):
for i in range(0, len(l), n):
yield l[i:i + n]
for slicerange in divideChunks(objs, 10):
myobjects = my_model.objects.filter(creator__in = slicerange)
...
