- We're not gonna change that for this little example, but now let's check in that PWA files, and then let's deploy to production one more time. and as you can see, look in the top right corner, when I reload it, we now have that little install icon in Chrome. and if I click that little install icon, I'm gonna get this prompt, and boom! I have a PWA running in production for my Rails application.>> Rails 8.0.1 You are in good company
- we are in with production authentication for the entire system. all right one last thing, let me show how to turn this web application into a PWA as well.>> 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
- rails g authentication:
- Now, let's add authentication to things as well. Authentication is one of the newer feature in Rails, it basically gives you a default setup for tracking sessions, tracking passwords, and even doing password resets.>> 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
- You'll need to change that if you're working with other people of course, because you don't wanna check that master key into your Git repository,you're gonna wanna pull that out of one password when you go for real.>> Rails 8.0.1 You are in good company
- And you can pull that password from a bunch of different places, you can pull it from a credential store like one password, you can pull it straight out of Github command, as you can see here with the Github token above, or you can pull things out of ENV.>> Rails 8.0.1 You are in good company
- Furthermore, people that are bilingual earn fifteen to twenty percent higher salaries than people who speaks one language.>> To begin with
- 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
- 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
- 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

- Active Storage is a way to deal with attachments and other files in your Rails application. When you run it through action_text:install, it'll automatically set up those active storage tables that we need, there is one for blob,and then we have one for text here.We run migrations to set that up again, and now that we've run action_text:install, it also added a couple of gems, so we need to restart our development server. I do that just by exiting out and just running the server again!>> Rails 8.0.1 You are in good company
- Now, let's install something else here, let's install action_text, that is one of the frameworks that's part of Rails, but it's not set up by default, but you can set it up by running rails action_text:install, that's going to give you a WYSIWYG editor. That's currently powered by Trix! The open source, what you see is what you get editor made in JavaScript! And it also sets up active storage!>> 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
- auxiliary police:
- Now if we hop over and start up our development server, you do that with just bin/dev. If we were running a Rails application that also had auxiliary watcher processes such as one for ES build or for Tailwind, bin/dev would start those as well. But this version of our Rails blog, is just going to be built with all vanilla, no build swt up so we only need to start the Puma, Ruby web server,and we can hop over into the browser and see here.>> 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
- One of the things that we must do is that we must be involved in working on achieving self mastery. You must work on yourself continuously. Never be satisfied with yourself, always know that as you invest the effort and time on you.That's the greatest ability that human beings have above animals.>> Motivate yourself in the morning
- There is a great quote, "I'm sorry I wrote you such a long letter. I didn't have time to write a short one." That's respect to people.>> work hard but work smart

There was something in his mouth 最符合课文的真实情况，这也是作者不能讲话的唯一原因，其他3个选择都不是原因，所以只能选c. 2. b 根据课文第8-10行I suddenly felt very worried,…when the dentist at last removed the cotton wool… I was able to tell him that he had pulled out the wrong tooth 可以判断b. he thought the dentist had pulled out the wrong tooth 是作者着急的唯一原因，其他3个选择都不是他着急的原因，所以选b. 3. c 只有选c. cannot 才能使句子同前一句It is impossible for him to answer.(他是不可能回答的)意义相同,所以c.是正确答案.a. might not 与d .may not 都不符合题目意思. b. could not 时态不对. 4. b 本句是将前一句中表示命令请求的间接引语变成了直接引语(祈使句)。 a. To rest 是动词不定式，不能做祈使句的谓语; c. Do you rest是疑问句，不能表示请求; d. Resting 是动名词也不能做祈使句的谓语; 只有b. Rest 可以做祈使句的谓语,所以选b. 5. a 本句是将前一句中的间接疑问句...how my brother was 变成直接疑问句，因此时态和语序都要作相应改变。 b. your brother was, c. your brother is 都不是疑问句语序，所以都不对。 d. was your brother 语序正确，但时态不对：间接引语是过去时，直接引语应该是现在时才正确。只有a. is your brother 语序和时态都正确，所以应该选a. 6. c 这是一个疑问句，a. It likes you , b. Does it like you 和d. Like you 这3个选择都意思不通，不符合题目意思，只有c. Do you like 意思通顺，符合疑问句语序，因此只能选c. 7. b 介词by 后面加动名词可以表示方式。 本句只能选b. nodding(点头)，因为它是动名词，可以放在by 后面作方式状语。 其他3个选择都不能放在介词by 后面，所以选b. 8. b 本句需要选一个同前一句中时间短语for a while (一会儿)意义相同的短语。a. quietly (安静地)，c. while he spoke to me (当他跟我说话时)，d. for a long time (很久)这3个选择都与for a while 的意义不符。 只有b. for a short time (短时间)同for a while 的含义相同，因此选b. 9. d a. assembly (集会，聚会)，b. gathering (聚集，收集抽象的东西，如消息等)，c. congregation (聚集，聚合) ， d. collection (收集，收藏如邮票，硬币等)，只有d最适合这个句子，其他3个选择都不能与火柴盒连用，所以选d. 10. a 前一句 I nodded(我点头)表示同意，只有a. agreed (同意)才是这一动作所表达的含义。b. said no (说不)，c. shouted (高喊)，d. whispered (耳语) 这3个选择都不是nodded所表达的含义，所以选a. 11. b 本句需要选出同前一句中的Meanwhile(同时)意义相同的词或短语。 a. However(不过，然而);b. In the mean time(同时);c. Never the less(尽管如此，不过);d. Although(虽然);这4个选择中只有b.同Meanwhile 的意义相同，所以选b. 12. c a. took it off (脱下)，b. took it in (理解)，c. took it out (取出)，和d. took it up (从事于)4个选择中只有c. took it out 同前一句He removed the cotton wool from my mouth(他将药棉从我嘴里取出)的含义相同，所以选c.>> 48-Did You Want to Tell Me Something?
