Django Form Validation

Question

Is it possible to add form errors (not a field specific errors) to a form that is already validated (form.is_valid() is already called and the result is True)?

I have additional validation logic (with database requests) which I prefer to execute after standard form validation is passed, but it will be better to associate new errors with form

Or maybe I have to call this additional validation within clear() form function?

Try to check it in the clean method of the form after all, but check existing errors before. Like that..

clean(self):
    ...
    ...
    if not self._errors:
        # your extra check

If this is validation based on database requests, then it shound as model validation.

I don't have a model involved in these database requests, it's a raw sql that call one database function. And the result can indicate incorrect data in form, that's why I want to associate errors with form
