difference between get and filter in django
Difference between Django's filter() and get() methods
Basically use get() when you want to get a single unique object,
and filter() when you want to get all objects that match your lookup parameters
which means filter() is slightly expensive operation if the model class has a large number of objects, whereas get() is direct approach.filter vs get django
If you use filter(), you typically do this whenever you expect
more than just one object that matches your criteria.
If no item was found matching your criteria, filter()
returns am empty queryset without throwing an error.
If you use get(), you expect one (and only one) item that
matches your criteria. Get throws an error if the item does
not exist or if multiple items exist that match your criteria.
You should therefore always use if in a try.. except .. block
or with a shortcut function like get_object_or_404 in order to
handle the exceptions properly.Copyright © 2021 Codeinu
