How do I set up Flask-WTF in my Flask application?

To set up Flask-WTF, first install it using pip: pip install Flask-WTF. Then, import it in your app.

What do I need to do after installing it?

After installation, you need to configure your Flask app with a secret key and create a form class that inherits from FlaskForm.

Can you show me an example of a simple form?

Sure! Here's a basic example:

from flask_wtf import FlaskForm
from wtforms import StringField, SubmitField

class MyForm(FlaskForm):
    name = StringField('Name')
    submit = SubmitField('Submit')

How do I render this form in a template?

You can render the form in your template using Jinja2 syntax like this:

<form method="POST">
    {{ form.hidden_tag() }}
    {{ form.name.label }}
    {{ form.name(size=32) }}
    {{ form.submit() }}
</form>
