Changes between Initial Version and Version 1 of Ticket #24489, comment 1

initial	v1
1	1	I'm marking this as invalid:
2	2
3		- Validation is not handled by the model, but rather by the database and model forms. Model forms enforce the minimal value.
	3	- Most validation is not handled by the model, but rather by the database and model forms. Model forms enforce the minimal value.
4	4	- The documentation makes no claims on which values are not supported, only on which values are guaranteed to be supported. Other than that, it is backend-dependant. SQLite does not enforce any restrictions, but most other backends do.
5	5	- The value on a model is never changed by saving it, so `post.views` will always be `-10` instead of the actual database value. For MySQL and probably other backends, the value is correctly set to `0` when reloaded from the database.
