- 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
- And if we hop into our comment, we can set up a broadcast_to for that post. The broadcast_to will broadcast all update made to that comment, whether a new comment is updated or an existing comment is changed in some way or even one deleted, and send it back out to a channel on action cable named after the post association that this comment belongs to!>> 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
- Now that we have that up, we can hop in and look it all up into the show action for the posts! That's gonna reference that common slot comments, that includes both the comments and the new form.>> Rails 8.0.1 You are in good company
- Alright, if we hop into that comments controller, it was empty. As you can see there, I'm gonna pay something in that actually makes this stuff work! You'll see one principle of the controller setup we have is that we have these callbacks. Before action, we're gonna set posts. So before all the actions, we're going to reflect the fact that this is nested resource.>> Rails 8.0.1 You are in good company
- So, let's run the migration for that, that sets up the comments table. You can see here the schema that we've now built up. We've added a number of tables for action text and action storage. And then, we have added a comments table. That's what you can see here. As we had it in the migration where we were just referencing the post as a foreign key, and then we had the content as text.>> 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
- console instance variables:
- Now, let me show you one of the first feature here. If we do raise exception inside the index action, "rails 'some exception' " you will see that Rails provides some really nice interface for dealing with that exception, seeing exactly where it happened. If I'm reloading here, you can see the line, it was raised on the source code that's around it, you can see a full trace. And down here, we even have a console! So, you can interact with the instance variables that have been set for this index actions, here's just at posts that's been made available.>> Rails 8.0.1 You are in good company
- This is the thing you're gonna see, when you start up a new Rails application, it'll tell you which version you're on, both for the ruby version, the Rails version, and the Rack version. That's running on localhost:3000 by default. But if we do slash posts here, you'll see the scaffold interface that we generated. Now, this is the index action, the one we just looked at in the view and from the controller. But if we click the New, you see here we have form for creating the new post with its title and its body. it's quiet basic, to put it mildly right now, but all the actions are mapped out. This scaffold interface is not meant for shipping into production, it is meant to showing you how to build a Rails application with the basics, and then you make it look pretty, you make it look nice.>> Rails 8.0.1 You are in good company
- find it straight off an ID:
- And if you scroll down here, you can see we have everything served in two flavors, we have both the HTML setup that'll render views directly, and then you have JSON that'll render for and an API. And as you can see here, we're also setting up a new post for some of those actions that require that, we're gonna find it straight off an ID passed in through the URL, and the post parameters are the ones we're using when we're creating and updating the application.>> Rails 8.0.1 You are in good company
- All post controllers follow the same convention. There are seven actions, you have index,show, new, edit, create and update and destroy! So there form a basic setup for configuring everything that's needed for a resource to be exposed to the web.>> Rails 8.0.1 You are in good company
- So, let's jump into the post controller first. The controller is really what guides all the inbound actions you get into a Rails application, you'll have the user hitting (slash)/posts or /post/new, and it gets routed into the posts controller!>> Rails 8.0.1 You are in good company
- Soon we will put my excellent plan to action.>> Madagascar (2005)Movie Script
- On top of the trifecta of Solid adapters that makes it possible for SQLite to power Action Cable, Rails.cache, and Active Job, a bunch of work has gone into making the SQLite adapter and Ruby driver suitable for real production use in Rails 8.
除了使SQLite能够为Action Cable、Rails.cache和Active Job供电的Solid适配器之外，还进行了大量工作，使SQLite适配器和Ruby驱动程序适合Rails 8中的实际生产使用。>> Rails8- GitHub users are now required to enable two-factor authentication as an additional security measure.
