function-decorator , which is checking an access according to USERNAME

[deanhystad]

No, it does not work correctly. Try this:

@is_auth
@has_access
def from_db():
    print("some data from database")
 
@has_access
def open_forum():
    print("log onto the forum")
 
from_db()
open_forum()

calling from_db() and open_forum() should each ask if you want to enter credentials. Your code works for one test, it needs to work for all tests.
