Hello
Thanks Leni, Scott for replying. I had tried that previously.
user.is_authenticated cannot be set. It throws an error.
I had stumbled upon a tutorial where user.authenticated had been set and so
thought that was the proper way to modify the value
of user.is_authenticated. When I set user.authenticated in the code, the
app didn't throw any errors which further bolstered my
previous beliefs. It's just that setting it seems to have no effect or its
effect is reversed by the time login_user(user) logs you in to
the next view. Just after setting user.authenticated to True, I issue a
print statement to check the the value user.is_authenticated
and it shows True. By the time login_user(user) logs me in, I issue another
print statement and user.is_authenticated has reverted
to False.
