How can I customize Django form extensions?

You can customize Django form extensions by creating custom fields, widgets, and validators. What specific customization do you have in mind?

I want to create a custom field that validates a phone number format.

You can create a custom field by subclassing forms.Field and overriding the clean method to implement your phone number validation logic.

Can you show me an example of that?

Sure! Here's a simple example:

from django import forms
import re

class PhoneNumberField(forms.Field):
    def clean(self, value):
        super().clean(value)
        if not re.match(r'^\+?1?\d{9,15}$', value):
            raise forms.ValidationError('Invalid phone number format.')
        return value

Thanks! How do I use this custom field in a form?

You can use it like any other field in your form class:

class MyForm(forms.Form):
    phone = PhoneNumberField()
