I write the source code, and my learning was more convenient because I identify details from tiny errors in the code. Thanks. You can permit work and learn.
I was wondering the same thing and after a few trials and errors, I managed to get it working. Let's say for the purpose of the exercise that you added in you Post Model a validates_presence_of method on the :title attribute. If you then tried to create a new post by leaving the title field blank, the create method in your posts_controller would fail to save the new record and thus return an error hash. This error hash is the @post.errors in the else clause of the create method. So, the basic idea is to check in the js.erb file if the backend returned any errors. If it did, you need to loop through the hash and extract the messages. If it didn't, then add the new post as shown in the tutorial. Here is the simple solution, of course you can always move the code around a bit and display it to your liking in you view.

Wow..Thanks..It works.. really appreciate it. The errors stick there even when changing page, Its only gone when I refresh the page..Any idea how to handle it?
hi! perfect demonstration! But some codes are not visible and I did not find the source files in the website. Could you share with us the code, please?
Excellent tutorial, congratulations. What happens when the model has validations? For example "validates_presence_of: title" I tried to create an item that does not comply with the validation, but no error message is displayed to the user. How to solve it?
Hi, thanks for the videos. I have a question because it works mostly times,i mean, first time the page is loaded it does not work and i have to refresh the page and then it works. Do you know why it could be happening?
Same problem here. Didi fixed it? I alread compare with the github of stukio. When I clone the github everything works fine. I think the problem is with the gems version. I dont know
Relax, breath, calm down. You are doing good :) keep a good flow going and practise the technical language so you don't need to freak out when explaining something and the word just wont pop in ti your head. Also please stop clicking with your mouth (it is extremely annoying due to the mic being very close)
By far one of the most annoying attempts at a technical tutorial that I've had the misfortune to listen to. Considering TH-cam's range that's a bold statment, but if you can make through the lip smacking he'll start using some very basic ajax at about the midpoint.
I'm very happy I found your videos. Keep up the great work!
Thanks a lot Sir!

At first I thought it was going to be clear and simply explained but at 6:50 he completely lost me
Good video, but you gotta chill out bro. It is quite annoying when you keep mistyping words.
