Problem with adding role based access decorator to the Flask function - flask

Question

I want to implement role based access to resources, for that purpose i have decorator functions:
def permission_required(permission):
def decorator(f):
#wraps(f)
def decorated_function(*args, **kwargs):
if not current_user.can(permission):
return jsonify({'message' : 'You dont have right permission!'}), 401
return f(*args, **kwargs)
return decorated_function
return decorator
def admin_required(f):
return permission_required(Permission.ADMIN)(f)
def token_required(f):
#wraps(f)
def decorated(*args, **kwargs):
token = None
if 'x-access-token' in request.headers:
token = request.headers['x-access-token']
if not token:
return jsonify({'message' : 'Token is missing !!'}), 401
try:
data = jwt.decode(token, current_app.config['SECRET_KEY'], algorithms=["HS256"])
current_user = db_session.query(Account).filter_by(public_id=data['public_id']).first()
except:
return jsonify({
'message' : 'Token is invalid !!'
}), 401
return f(current_user, *args, **kwargs)
return decorated
which are called above test function:
#auth.route('/testing', methods=['GET'])
#token_required
#admin_required
def testing(current_user):
print(current_user.can(Permission.ADMIN))
return "successful"
#token_required function works fine but when I add #admin_required decorator it fails and throws
following error:
File "/home/pi/backend/src/api/auth.py", line 43, in decorated
return f(current_user, *args, **kwargs)
File "/home/pi/backend/src/api/auth.py", line 19, in decorated_function
if not current_user.can(permission):
NameError: name 'current_user' is not defined
Kindly, advice what's wrong and how can I fix that
