Sure! Here's an example:

from django import forms

class MyForm(forms.ModelForm):
    class Meta:
        model = MyModel
        fields = ['my_field']
        error_messages = {
            'my_field': {
                'required': 'This field is mandatory.',
                'invalid': 'Enter a valid value.',
            },
        }

You can add custom validation logic by overriding the clean method in your form class. This allows you to raise validation errors with custom messages.
