What is the structure of WTForms forms?

WTForms forms are structured using classes that define fields, validation, and rendering. Each form is a subclass of the FlaskForm class.

Can you explain how to define fields in a WTForms form?

Sure! You define fields as class attributes in your form class. For example, you can use StringField, PasswordField, etc.

How do I add validation to these fields?

You can add validators as arguments to the field definitions. For instance, StringField('Name', [DataRequired()]) ensures the field is not empty.

What about rendering the form in a template?

You can render the form in a Jinja2 template using {{ form.field_name() }} for each field, or {{ form.hidden_tag() }} for CSRF protection.
