Raise validation error from child form on parent form in Django

Let's say I have this form:

from django import forms
from django.core.exceptions import ValidationError

class NameForm(forms.form):
    name = forms.CharField(max_length=200)

class NameAgeForm(NameForm):
    age = forms.IntegerField()

    def clean(self):
        data = self.cleaned_data
        if data.get('age') == 24 and data.get('name') == 'Nebu':
            raise ValidationError({'name': "You can't pick that name and age, they are mine!"})

The thing is, I have a sub-form where validation is happening. But I want my field error being shown at the NameForm.

Sidenote I can't access the parent form and therefore the solution must come from the child.

Now, is this possible?

Clean() method on your NameAgeForm It must add custom validation for each field. For field-specific validation, This field validation specific to your current form, We don’t want to put it into the ChildForm. Instead, we write a cleaning method in ParentForm. So Django doesn't help you.
