Now, let's add a way to sign out to the main layout here. we can add that with a button to sign out.it's gonna hit the session path, and it's gonna use a method of delete that session if we're authenticated, as you can see there.
>> Rails 8.0.1 You are in good company

But as you can see here, it adds a handful of migrations, one for users, and one for sessions! So, we're gonna run rails db:migrate again!
>> Rails 8.0.1 You are in good company

Common system is of course these as well, let's add one of those comments, and now we have the entire application running in production, wasn't that easy?
>> Rails 8.0.1 You are in good company

And that is basically it. Now if I go over here and I add a comment to one of these, you see the comment was added on the left immediately at the same time. That's all web sockets automatically happening through action cable. And we can do it , of course the other way as well.
>> Rails 8.0.1 You are in good company

So if we scroll down to the bottom here, we are ready. The first thing we're gonna do, we're gonna add a turbo stream from post to the show files to the show template.That's gonna set up the web socket connection and subscribe us to a channel named after that particular post that's pasted in.
>> Rails 8.0.1 You are in good company

Now, let's set things up to be dynamic, such that when we add a new comment to one of these, it's going to update the other as well. This is how we use web sockets in Rails using action cable, one of the frameworks that we have to create updates that are distributed automatically without folks having to reload their browser.
>> Rails 8.0.1 You are in good company

When it is nested, we get the fact that it's gonna be slash post slash on slash comments, and we have the association is set up nicely. Now, let's reload! Now it works, we have our comments field underneath. we can add the first comment. And as you can see here, this is my first comment a second ago that was the local time doing its time ago conversion.
>> Rails 8.0.1 You are in good company

And then, Rails by default also adds two timestamps that it keeps track of by itself, created at and updated at. And below that, you had the post that we added originally.
>> Rails 8.0.1 You are in good company

Alright! Now let's add some comments to our blogging system! And I'm gonna use a different generator here,I'm gonna use a resource generator that is a little lighter than the one we were using for scaffold that doesn't generate a bunch of views, and doesn't generate all sorts of actions in the controller by default, but it does generate the new model that we need the comment model, it generates a migration for that, create comments ,and it generates just some empty placeholders for the comments controller and for the view action.
>> Rails 8.0.1 You are in good company

We're including trix and action text to give the WYSIWYG, and now we're gonna add that local text package as well. "import LocalTime from 'local-time' LocalTime.start()"
>> Rails 8.0.1 You are in good company

But now that we've add that, let's have a look at our application JS file.That's the default setup that you have that the scaffold is going to use. And as you can see, we're using turbo-rails, we're including all the stimulus controllers, if we have any.
>> Rails 8.0.1 You are in good company

And then, there's the stimulus framework for creating that additional functionality that you might need in a really simple way. You can have a look at hotwire.dev to see more about that, but what we're gonna add here is a little piece of JavaScript to just add some additional functionality, pulling something in from pin.
>> Rails 8.0.1 You are in good company

Now, let's add a bit of custom JavaScript. Rails by default ships with Hotwire! Hotwire gives you Turbo, which is a way of accelerating page changes and updates is that your application will feel as fast and as smooth as a single page application without you basically having to write any JavaScript at all.
>> Rails 8.0.1 You are in good company

As you can see here, there is now a full WYSIWYG interface for creating the body. It comes with a default set of styles for the toolbar, you can change those, those styles are generated straight into your application, so you can make it look nice for yourself. Let's give some bold and italic text here, you see, that was all that was needed. but I think what's even nicer to look at here is if we do an upload and we add a file, you will see that file gets added with a preview directly to the WYSIWYG editor. And if we save that and we update the post, it is added to the post itself. And that then went through the whole process of doing a direct upload of the file when we dropped it into the editor, that uploads it straight to active storage. And then, we have access to that, and rendering it directly from whatever storage backend active storage is using. In this example , we're just storing on disk, but you could be storing your active storage in S3 or another object storage.
>> Rails 8.0.1 You are in good company

Now if we hop back into our editor here, I can add a little bit of styling to make this look slightly nicer than the very basic layout that you get with the scaffold.
