We saw we can register and we saw we can drive the user interface based on whether or not there is a user
0:07
even from remembering us from session to session, right? So if I run this now we'll see that account and logout are shown
0:14
but that login and register are not. However, we probably want to let them log out at some point, right?
0:21
So let's go do that, that turns out to be super, super easy. So when you go down here and you click this you see Anvil.users.logout. Not too hard, huh?
0:33
And we also want to go back home and set this user state. Okay, so we're going to go do those three things. I'm going to log out
0:43
and then we want to set this to be None because we've logged them out and then we're going to go home that's going to trigger a refresh
0:51
of potentially that home screen and show the anonymous view. if you're on the home screen, of course it's just going to toggle that
0:57
but if you were maybe somewhere else like in your account page got to take 'em somewhere that's valid and home is always valid. Let's run that.

All right, we're logged in, as you can see right here. I click logout, it should change this menu. Should re-navigate us home
1:11
which is going to reload this to home anonymous view. Let's give it a shot, here we go. Again, the cell. All right, let's try it one more time.
1:21
Well, our logout worked. We just weren't able to update.
