django-health-check

This project checks a number of backends, if they are able to connect and do a simple action, e.g. check out the django ORM backend:

class DjangoDatabaseBackend(BaseHealthCheckBackend):

    def check_status(self):
        try:
            obj = TestModel.objects.create(title="test")
            obj.title = "newtest"
            obj.save()
            obj.delete()
            return HealthCheckStatusType.working
        except IntegrityError:
            return HealthCheckStatusType.unexpected_result
        except DatabaseError:
            return HealthCheckStatusType.unavailable

The project is made using some of the same codes, that the django admin site uses - so when you have sucessfully written a new plugin, you register it to the pool, e.g.

plugin_dir.register(DjangoDatabaseBackend)

Installing
