What are Django form fields and how do I use them?

Django form fields are components used in Django forms to handle user input. They define the type of data expected, such as text, email, or date.

Can you give me an example of a text field in a Django form?

Sure! You can create a text field in a Django form like this:

from django import forms

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

What about validation for these fields?

Django provides built-in validation for form fields. For example, if you want to ensure the name field is not empty, you can set required=True.

How can I customize error messages for form validation?

You can customize error messages by passing the error_messages argument when defining the field. For example:

name = forms.CharField(error_messages={'required': 'This field is mandatory.'})
