Here i explained simply step by step django how to use limit and offset in django query:Syntax:
So, django utilizes the array slicing syntax of python to implement limit offset. for pagination in django models, you need to use limit offset. suppose you have 20 rows in a queryset and you want to access the data in batches of 5.
For example, this returns the first 5 objects (LIMIT 5):
This returns the sixth through tenth objects (OFFSET 5 LIMIT 5):
Note: Negative indexing (i.e. Entry.objects.all()[-1]) is not supported.
Further filtering or ordering of a sliced queryset is prohibited due to the ambiguous nature of how that might work.
To retrieve a single object rather than a list (e.g. SELECT foo FROM bar LIMIT 1), use an index instead of a slice. For example, this returns the first Entry in the database, after ordering entries alphabetically by headline:
This is roughly equivalent to:
Note: however, that the first of these will raise IndexError while the second will raise DoesNotExist if no objects match the given criteria. See get() for more details.
