I would like to know how to add all the data in a column of my database.
This is my model:
class Model(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE, null=True) id = models.AutoField(primary_key=True) number = models.FloatField(default=0) created = models.DateTimeField(auto_now_add=True, null=True)
I would like to obtain the sum of all the data in the number field to then perform an operation, the methods I know are the following but I do not know how to use them:
I want to do something like that but I do not know how to apply it:
obj = Model.objects.all().filter(user=request.user) obj.number variable_1 = 10 variable_1 = 10 + obj.number # La suma de todos los registros del campo number
thank you very much friends
