Every field in Form has validators which check the value against their conditions. as Django Doc sais <https://docs.djangoproject.com/en/2.1/ref/forms/api/#django.forms.Form.is_valid> : The primary task of a Form <https://docs.djangoproject.com/en/2.1/ref/forms/api/#django.forms.Form> object is to validate data. With a bound Form <https://docs.djangoproject.com/en/2.1/ref/forms/api/#django.forms.Form> instance, call the is_valid() <https://docs.djangoproject.com/en/2.1/ref/forms/api/#django.forms.Form.is_valid> method to run validation and return a boolean designating whether the data was valid
Take a look at is_valid at Django source code <https://github.com/django/django/blob/cbf7e71558c94ce1c327b683768a18a25d82d197/django/forms/forms.py#L178> (At BaseForm's source code). as you see there it checks if the form is bound and *not has errors.* If you see *errors*, it's a method with attribute decorator. that triggers the full_clean( ) method. full_clean does _clean_fields which populates the *cleaned_data *with validation checked data. So, If you call the is_valid() and it returns True, You know that all form validators are applied to the data and it had no errors. also the cleaned_data is ready to use.
