distinct

.distinct() is the tool, but here’s the syntax I had to use :

Model.objects.values_list('name', flat=True).distinct()

This way you only get a list [A,B,C,D] of values, not the objects themseleves.

Pek zarif olmasada aşağıdaki de kullanılır.

# Fetch all rows to limit num of queries
all_rows = MyModel.objects.all()

# Query against the full list to return a list of objects
item_list = [all_rows.filter(myfield=item['myfield']).last() for item in MyModel.objects.values('myfield').distinct()]
