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

To set up Flask-Principal, first install it using pip: pip install Flask-Principal. Then, you can initialize it in your app.

What are the main features of Flask-Principal?

Flask-Principal provides user authentication, role management, and permission handling, making it easier to manage user access.

Can you show me a basic example of how to implement it?

Sure! Here's a simple example:

from flask import Flask
from flask_principal import Principal, Permission, RoleNeed

app = Flask(__name__)
Principal(app)

admin_permission = Permission(RoleNeed('admin'))

@app.route('/admin')
@admin_permission.require(http_exception=403)
def admin():
    return 'Welcome to the admin page!'
