How can I handle validation errors in Django forms?

In Django, you can handle validation errors by overriding the clean() method in your form class. This method allows you to add custom validation logic.

Can you give me an example of how to override the clean method?

Sure! Here's a simple example:

from django import forms

class MyForm(forms.Form):
    name = forms.CharField(max_length=100)

    def clean_name(self):
        name = self.cleaned_data.get('name')
        if 'badword' in name:
            raise forms.ValidationError('Inappropriate word used!')
        return name

What happens if there are multiple validation errors?

If there are multiple validation errors, Django will collect all of them and display them in the form's error messages. You can access these errors using form.errors.
