I'm marking this as invalid:

  • Validation is not handled by the model, but rather by the database and model forms. Model forms enforce the minimal value.
  • 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.
  • 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.

So while it might be semantically incorrect to support negative values, it's not a bug, and changing it would be backwards-incompatible. Feel free to add a note to the documentation, though.
