This Django model mixin adds an incr_count method that increments the “count” field in one SQL query (very useful if same object can be updated simultaneously and you want the count field to have correct values).

Raw

incr_count_mixin.py

	class CountIncrMethodMixin(models.Model):
	def incr_count(self):
	model = type(self)
	model.objects.filter(id=self.id).update(
	count=models.F("count")+1
	)
