What is the structure of a WTForms form?
A WTForms form typically consists of fields, validators, and a submit button. Each field can have its own validation rules.
Can you give me an example of a simple form?
Sure! A simple form might include a 'Username' field, a 'Password' field, and a 'Submit' button.
How do I add validation to the fields?
You can add validation by using built-in validators like DataRequired, Length, or Email. For example, username = StringField('Username', validators=[DataRequired()])
.
What if I want to customize the error messages?
You can customize error messages by passing a message parameter to the validator, like this: DataRequired(message='This field is required.')
.
