object.create in django code example

Example 1: django objects.create()

SomeModel.objects.create(firstname='ricky', lastname='ticky')

Example 2: django delete object

SomeModel.objects.filter(id=id).delete()

Example 3: django get or create object

try:
    obj = Person.objects.get(first_name='John', last_name='Lennon')
except Person.DoesNotExist:
    obj = Person(first_name='John', last_name='Lennon', birthday=date(1940, 10, 9))
    obj.save()

Here, with concurrent requests, multiple attempts to save a Person with the same parameters may be made. To avoid this race condition, the above example can be rewritten using get_or_create() like so:

obj, created = Person.objects.get_or_create(
    first_name='John',
    last_name='Lennon',
    defaults={'birthday': date(1940, 10, 9)},
)
Any keyword arguments passed to get_or_create() — except an optional one called defaults — will be used in a get() call. If an object is found, get_or_create() returns a tuple of that object and False.

Example 4: .save() in django

>>> one_entry = Entry.objects.get(pk=1)
