Specifying limit and offset in Django QuerySet wont work-StackOverflow
django 官网文档
Use a subset of Python’s array-slicing syntax to limit your QuerySet to a certain number of results. This is the equivalent of SQL’s LIMIT and OFFSET clauses.
For example, this returns the first 5 objects (LIMIT 5):
Entry.objects.all()[:5]
This returns the sixth through tenth objects (OFFSET 5 LIMIT 5):
Entry.objects.all()[5:10]
Negative indexing (i.e. Entry.objects.all()[-1]) is not supported.
