So that is a very quick tour of Rails, this is a wonderful way of getting started,just to use those scaffold generators and the authentication generators to get something going, get a Hello world out there, start working on your application, and before you know it, you might just be taking your application all the way from Hello World to IPO.
>> Rails 8.0.1 You are in good company
这是Rails的快速浏览，这是一种很好的入门方式，只需使用这些脚手架生成器和身份验证生成器即可开始工作，创建一个Hello world，开始开发你的应用程序，不知不觉中，你可能会把你的应用程序从Hello world一直带到IPO。
We're gonna turn the manifest on in our route file as well. There are basically two lines here as you can see, there's a manifest, and there's a service worker that you can use for your PWA.

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.

By default, Kamal will use a docker volume to start these things up, but of course, you can configure that, and as I said, you can use S3 if you'd like as well.
>> Rails 8.0.1 You are in good company
kamal setup:
But this is all we basically need, we are now ready to check in the entire project into Git! Kamal uses Git for keeping track of versions, and we can now run Kamal setup!
>> Rails 8.0.1 You are in good company
Now I'm gonna deploy this on my own little hoppy server. And that hoppy server is currently wiped. it is completely clean, and Ubuntu 24.04 setup that has nothing on it already, this is part of the magic of Kamal, you can spin up a new VM anywhere in the cloud or use your own hardware and point Kamal straight to it, and you'll be going in no time!

Docker Hub:
And there's a default configuration file in config/deploy.yml that we can use, it's prefilled a little bit, it has the service name of the name of reaction, but we need to rename, for example, your user,the name of the image to go to my name of where I store this on Docker Hub. You can see we change that down in the registry as well and the name of the container image.

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
And then finally, let's paste in the form that we're gonna use. That form is going off a model, the new comment, but it's nested underneath the post, is that we automatically can deduce which URL that we should post this new form to.
>> Rails 8.0.1 You are in good company
We are pacing in the comment, and we're using that same time tag as we were using with the post, but this time, we are going to use time ago, so we get that nice two minutes ago on when something went posted rather than a local time spelled out with AM PM set up.
>> Rails 8.0.1 You are in good company
It'll automatically know that the comment model should map to view slash comment slash comment, so it can look up the right partial file to use. And then below that, we have the form that we're referencing with the comments new. So, let's hop in and paste in the individual comment. As you can see here, we just give it a div, that has a dom ID so that we can reference it.
>> Rails 8.0.1 You are in good company

Now, we're also gonna add a number of partials here. This is the templating system, basically, a sub-routine that you can refer to. There's gonna be three of them that includes the entire comment section. We're gonna reference that in our post show in just a second. And within that, we're gonna refer to another partial for an individual comment, and another partial again for the new setup. So, let's paste some of that in here, You can see this for the entire collection, it just has an H2 for the comments, and we render the post comments. This again uses Rails' convention over the configuration approach.
>> 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.
