💡 Hint

Common Mistakes

Using incorrect attributes that do not exist on app.

Trying to call methods instead of accessing attributes.

app.view_functions is a dictionary mapping endpoint names (which correspond to URL rules) to view functions. Iterate with .items() and use func.__name__ for the function name.

💡 Hint

Common Mistakes

Using '@app.route' instead of 'register_blueprint'.

Missing the slash in the URL prefix.

Using the wrong blueprint name.

Blueprints are created with a name like 'auth' and a URL prefix like '/auth'. They are registered on the app with app.register_blueprint(bp).
