Transcript excerpt
0:00 you may have some pages in your application that should only be available to authenticated users otherwise you either redirect them to the login page or simply show them on error let's see how Tac RoR can make this happen this is chapter four of this series let's get started back to our example let's see I want to navigate to the profile page only after logging in so first of all let's create a login route here with some code already written which basically is a simple login text if the user is authenticated
0:32 hello user and a sign it button if the user is not authenticated we have a sign in button pretty easy right I can add the link here to the login page so login you see as usual it's type save log here and there you have it I click login and I can sign in hello user and I can sign out it is working but there's not yet the control on the profile page so let's make this happen in the second video we saw how you can basically Define a
1:04 loader here in the rout to do something before the page loads but you can do something before the loader and we can see it in the profile component here we can say before load and this is exactly the place where we're going to put our authentication guard and it is as easy as using an if statement we can use the is authenticated function we have in our other file and if the user is not authenticated we can throw not an error
