aruseni / incr_count_mixin.py

Last active April 13, 2016 09:58

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).

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