Get the latest record with filter in Django
latest
is really designed to work with date fields (it probably does work with other total-ordered types too, but not sure). And the only way you can use it without specifying the field name is by setting the get_latest_by
meta attribute, as mentioned here.
See the docs from django: https://docs.djangoproject.com/en/dev/ref/models/querysets/#latest
You need to specify a field in latest(). eg.
obj= Model.objects.filter(testfield=12).latest('testfield')
Or if your model’s Meta specifies get_latest_by, you can leave off the field_name
argument to earliest() or latest()
. Django will use the field specified in get_latest_by
by default.
obj= Model.objects.filter(testfield=12).order_by('-id')[0]
last() latest()
Usign last():
ModelName.objects.last()
using latest():
ModelName.objects.latest('id')
