So FCC actually provided us a tutorial by someone with 2 best sellers on ruby. Incredible!
lmao, 2 "best sellers" is subjective and hardly an achievement for anyone well versed in Ruby.
@@hiddenaether Sure, except only a small percentage of people ever even write a book, so I'd say it's an achievement for anybody.
Not nesvessarily. I remember looking for a book on C++ and kept finding books with errors in them. It was a long time ago, so I only remember one of them, but there were a few that almost every book made. The one that stuck in my mind is that almost all the authors kept referring to "data structures" as "data".
It may seem like something insignificant to many but there is a difference.
It got to the point where In would scan the book quickly to check for those errors and discarded it when I found,them.
I did find a book whose author did not make those errors and bought it.
@@hiddenaether haters gonna hate 🤣😂🤣☝️
Omg this joke is funny 😂 no one would actually get the FCC also means Federal Communications Commission that handles all of this 😂and is also this group of free coding camp. No lie this was genius
thanks for going over this in such a way that feels as if youre actually explaining to someone who is learning and not someone who has 10 + years developing and is taking a refresher
So I was here when this video had a less than hundred views and I was learning rails. Hands down, best tutorials I could find when I needed guidance and help in understanding rails. John Elder helped in the way I never thought someone could help other person.
And appreciating him is the least I could do.
For someone just starting out with rails, this tutorial is the best kick-start to the journey. And be persistent, it's gonna come to you :)
I completely agree with you Anish. John Elder is an incredible teacher. I'm new to rails too. I came across him about a week ago and picked up 4 of his courses in a Udemy sale a couple of days later. They are project based with fast facts coming at you in an easy to understand way.
Mr.Anish hope u are ok today ,would you recommend me learning rails today in 2023 .Am asking because finding a job is most important after learning .Please advise.Kind regards.
@@ezziwa Sorry for the late reply. And to answer your question, yes I'd totally learn rails today as well. I am working on rails at presently and there are plenty of jobs out there. Good luck to you
This is a good one! I started my Rails journey 3 months ago and tried to follow along 4 different tutorials and got lost during the process. I stumbled upon this and finished it within 2 days alongside my regular mundane work and was not distracted. It is worth giving it a try. I have enjoyed it very much. Thank you!
For those having trouble with tzinfo-data:
1. gem uninstall tzinfo-data
2. In the Gemfile, replace 'gem "tzinfo-data", platforms: %i[ mingw mswin x64_mingw jruby ]' to just gem "tzinfo-data"
3. bundle install
thank you so much!!
Where do I find the gemfile?(step2)
thanks buddy
@@Bootskum1 You are correct, the `Gemfile` is inside the directory that has been made using the `rails new` command, open the `Gemfile` using a text edior (I used notepad++) and then replace gem "tzinfo-data", platforms: %i[ mingw mswin x64_mingw jruby ] with gem "tzinfo-data"
thanks, was lost
A really brief video to get familiar with Rails. I appreciate it. Keep up the excellent work.
For those having issues with the sign_out (destroy_user_session_path) do the following:
change "method: :delete" to "data: { turbo_method: :delete }"
i was searching and searching for a solution, thank you!
@@jayknows9596 no problem. I know the feeling haha.
You saved me🙏
thank you, mate! God blessssss
Thanks!
Overall this was a good tutorial. I was expecting more detailed explanations as to what exactly we are coding but it is more project-based where you code along. Also, as the video gets older it is important to note that there will be a number of issues you will run into.
1) There is about an hour spent on styling using Bootstrap. The version used is outdated and some parts are deprecated so you will need to make adjustments.
2) The Rails autogenerated pages for the Friends section is quite different than what is shown on the video
3) There is not much explanation as to what is going on in when Rails autogenerates stuff so that we can somehow troubleshoot any errors we may be having.
4) Ive ran into issues with destroying a friend, Sign in error. There are a few more other users have mentioned so check the comments to see what adjustments you may need.
its free content bro, reading docs that align with your version and googling goes a long way in troubleshooting
@@kevinren3753 Relax. He's only pointing out the issues with a two-year old programming tutorial, which is quite important to new users.
Thanks for this. I know lengthy videos like this are usually judged by the name instead of the actual content, so it's good we get an idea of what to look for.
@@maxcohen13 lol im just saying, read the docs, tutorial videos are almost never enough on their own, best of luck.
use this instead if you use link_to data: { turbo_method: :delete, turbo_confirm: 'Are you sure?' }
This has been an incredible teaching; was damn easy to learn and implement parallelly. Thank you John for helping me in my ROR journey.
As someone who's been cursed with errors and other headaches related to coding, the sigh of relief I breathed when everything worked during the introduction was GREAT. Thanks for this tutorial, your channel is extremely helpful.
i bought a full corse in this and this YT video you posted for free is leaps and bounds more descriptive, you explained everything in way that makes one feel not so overwhelmed. Thank you Sir
Awesome content! Thanks for the 4 hours of pure wisdom and very well planned teaching
I was waiting for this video from this channel, finally❤
buummm said the peeled! Yes now! Thank you very much John. I finish the CRUD and Login with Ruby on Rails course and post on Heroku too. Thanks a lot!
Just finished and deployed the app. Love it, definitely highly recommended. Will check out your other courses. Thanks :)
Best ROR tutorial for beginners! Believe me this is the first time I've felt like commenting for a tutorial video. This tutorial covers all aspects right from scratch to deployment. Something every beginner wants to learn. 'John Elder' does the best job here. Thumbs Up, Wayyy to go...Cheers man :D
Couldn't agree more with every word ❤️
This is one of the best tutorials I have ever followed since I started studying rails. I have to say that you explain it very well and every instruction that I have followed has worked perfectly. Thank you very much and please continue sharing knowledge like this.
thank you very much and Happy New Year 2021.
Great teacher/lecturer yes, but for other languages, you have to find other lecturers like Kylie Ying for Python. Mike Dane is good for C++, although he offered both C++ and Python, I rate him well, almost 100% for C++ but not for Python [a point from Multivariate Models - be able to remove irrelevant features and then validate or rank non-redundant features]. Ka Modimo.
In a Multivariate Model we aim to - remove irrelevant features and then validate or rank non-redundant features, thereby reaching/achieving Learning Accuracy with better performance. Division of ML - a consistent or the best feature selection. Ka Modimo.
For y'all having a prob in the signout page, at 1:57:00 the "method: :delete" doesnt work. It needs to be "data: {turbo_method: :delete}" because rails-ujs got removed. Make sure to install turbo before by following these steps:
1-Add the turbo-rails gem to your Gemfile: gem 'turbo-rails'
2-Run ./bin/bundle install.
3-Run ./bin/rails turbo:install.
Thank you for this!
we need to install node and yarn
I can watch this all day without getting bored.
First time on rails great tutorial! One thing to add for future reference, when we add the bootstrap class to the Edit and Back on the friends view, do it like this :class => "btn btn-primary".
The one on the video broke for me on Rails 7.0.3, ruby 3.1.2p20
I was waiting for this one. Thankyou
Dude...I just started getting ready for a bootcamp....ty....You're a hero.
One of the best tutorials that I have followed. Thanks Jhon
This has to be one of the best Rails videos. Thank you for this content!
Wow great course! just finished my app! Thanks John!
Thank you very much, it was a pleasure to learn with you. Boom !!! :)
John Elder is the best Ruby on Rails teacher (youtuber)of the days in my humble opinion
Wow Thanks!
One of the best lectures I have seen. Successfully implemented and deployed.
About to finish the first 1 hour and I think this is the best, easiest to understand rails tutorial I've found so far. Thank you very much for putting this content online!
You guys are amazing and born to be teaching.......
This is so useful, thank you!
I’m speechless. This is one of the best tutorials I’ve ever watched. Anytime I start having a question you literally answer it seconds later. I will continue to reference this video as I work more with rails
Where do you contact him?
@@herbertsantos141 I meant in the video he ends up answering my questions like seconds later
I am indebted to this channel. This channel is our saviour.
the best course ever, i am a beginner but I can say I can now build a CRUD app will start testing my skill on building a difficult website
This course is amazing!!!! I went through the entire course, made some mistakes so I had to back track and fix some stuff but it wasn't unreasonable. The amount of things this framework brings is JAW DROPPING. Very easy to understand. Thank you for demystifying Rails for me!
God blesses internet and how fast you can download knowledge to your brain with videos!
I loved the intro to this lamenting that the hardest part about Ruby on Rails is installing it. Totally my experience. Took me two days to figure out all the installation.
Salutes, mr John Elder! You again! Thanks for the help with Tkinter in my database systems specialization! Thanks to your help and PAGE, I managed to make a GUI to access a Postgres DB.
I would appreciate a tutorial with React + Rails too from this guy
You are an energetic and gifted teacher. Keep up the great work.
just finished and deployed !!!! thankyou very much
John my man, you made are a great teacher. You made Django easy for me when it was too much for me, now I say this thumbnail with 4 hours timestamp and just randomly hovered and again saw John teaching stuff, no second thoughts clicked it and started thank you soo much dudeeee
I like python but i gave up on django
Good course but, there are some mistakes that I had following these instructionns.
You see, I'm using Rails 7 so it was different from Rails 6, so these are the changes:
I used this sintx in order to SIGN OUT
I had to change the submit buttons (sessions and registrations) functionality to:

I kept googling for this for hours and you saved me. Thanks!
@@user-jx5or8pk2m No problem! I know, there isn't much information about it. If you have another problem, maybe I could help you.
Thanks, this was causing some real frustrations!
@@JorgeOrtiz-qn3rw Do you have discord?
You're the best man
After I have been learning Rails on my own for three weeks, this video tutorial just solved many questions in my mind so easily. I will recommend this to everyone who wants to improve their skills in Ruby on Rails. Many thanks to the creators of this video. Great job!
Excellent tutorial for beginners with Rails! Thank you
Amazing Rails starter course!! Congrats! 🎉
Ruby, my first love! ♥️
Mine too. I continually try other newer "hip" languages, but Ruby always pulls me back in.
Great course!! Really enjoyed refreshing my rails skills with this fun project 🤗! Also curious if anyone else switched from .erb to haml? 🤔
No, the oppose will be True, erb for Now!

Iam microverse student now here it's my first time watched full tutorial with break or leaving half way ❤❤I liked tutorial and I know some version are updated and some outdated I will fix that but all I want to say is thank you John for making my journey rails easier😊
I have a problem with the DELETE method, it dosn't work for me (destroy link and sign out) they don't work eventhough i did the same thing you did in the video . also when I log in, the page only do the refresh thing and do not log me in. anybody Know why ? :(
Hello John,
First of all, thank you for this excellent course.
The migration you created in the Associations section actually just added the user_id field to the friends table and created an index on it, so actually it didn't create any foreign key or something between these two tables, so I couldn't understand why we wrote belongs_to or something inside the models.
Thank You for the amazing content!! MY First Full Stack Web Application with Custom backend
Really appreciate your content.
Please make a tutorial of Rust programming language.
YESSS!!!!!!!!!!!!!!!! RUBY COMEBACK LETS GOOOOOOOOOOOOOOOOOOOOOOOO
Yes, I am still using Jekyll.
Thanks to this wonderful tutorial! it was just great!!!
Best Rails Tutorial ever!!
I love ruby on rails so bad.
Heisenberg teaching rails.

we got heisenberg teaching rails before gta 6
Your video and teaching is excellent thankyou. I'm relatively new to web development and this is fantastic
I want to give a new like every two minutes! Great tutorial!
Incredibly good course to get started with Rails, learned a lot in 4 hours!
While some dudes told me that ruby is gonna die..... I think ruby have over 10 years left at least.
bro did u also got through the whole installation process and got error on localhost:3000? please help me out if u can
I just wanted to mention that I'm on linux and luckily my installation came with nodejs and ruby pre-installed. So a lot of the beginning stuff was already done for me. Yay me!
Thanks for such a great course!
It's year 2022 and this is the best ROR tutorial video PERIOD!
For anyone having trouble with the Sign up process on Rails 7, go to config/initializers/devise.rb and add this line
config.navigational_formats = ['*/*', :html, :turbo_stream] , then migrate and restart the server. And for those getting an error signing out replace the link_to line with this:
Thank you, this helped with the error I was getting on sign up!
You are a legend! Thank you so much. I was about to just quit this tutorial until I found your comment on the Sign up issue.

Throughout my coding journey kept sayin CRUD as Create Read Update Delete, and first time I have heard it's D for Destroy.
No Resourceful friend, It is mostly scaffolds all the times with them, then decided to just Destroy them all [CRUD]. Many students like that function, no Resourceful Database.
This is awesome! Very helpful content. Thank You so much!
Thank you, this video helps me much to understand basics of rails.
Had a issue with "gem install rails" in git bash. It failed over and over again even after updates. I fixed the issue by trying the same command in cmd, and then try it again in gitbash, and now it working perfect.
THANK YOU. I was having this same issue and this fixed it...after HOURS of troubleshooting...
@@lobster3496 No problems :)

To those who complain about outdated vesions or systems, just make adjustments. The information is still valuable to learn and understand.
This is a well put together tutorial and was exactly what I was looking for.
For anybody who had the same issue as me where :delete functionality isn't working (3:20:00) try button_to instead of link_to
Thanks a lot bro... I was about to give up on solving this problem🙏🙏
Maybe next time have a full screen of the code so we can see the entire written code. I followed this step by step and when it gets to thw style with bootstrap portion. Something with tbe current version of ROR makes it to where the index.html.erb friends file is incomplete. It just shows a div and not a table and thead
Same here, is there a specific step to take so we get the index.html.erb to have the a table & thead and not just a div ?
Thank you! Really great video and very helpful
You are great trainer & bring it very funny & honest
How is this free!? Incredible tutorial, and a great teacher!
Rails would be a lot more popular to use if it weren't for the windows issues.
amazing teacher, amazing language
It is the best tutorial and hands on on Ruby on Rails Dear Mosh you are like Kohinoor diamond hats up
Great video, thanks!
Just would point out that from 1:42:46 - 1:57:30, the part to get Devise working, I followed the video and got an error, took me some time to find out the issue, there is one step missing to create the controllers. Run this command and everything will be just working.
rails generate devise:controllers users
This will generate the controllers requires for the views.
hey i'm not able to get this running. pls help. Everything works and doesnt serve any error. But on the local host i'm unable to sign up. Terminal says transaction rolled back.
@@divijjain4674 , if you post code to github, might be much easier for others to check the code the code as of now.
hey man, could you please look at the code. Any help is appreciated. github.com/jaindivij21/friends-list
Thanks so much for this. I've been stuck on this part for days with "undefined method `user_url' for # ". I tried what you suggested but it still isn't working for me. Maybe I added something inadvertently when trying to fix it myself. I may have to just start from the beginning again. So frustrating to get everything right up to this point - then problems.
@@Bigdog33R , if you could upload code to github, I could take a look at to see what is the problem. The video was built on Rails 6, if you are using rails 7, might be slightly different.
good day sir. it seems that the railsinstaller.org is not anymore available.. is there other links?
It is down, alternatively you can install ruby, then in git bash run, gem install bundler, and then run, gem install rails, and it should work for you, after that you can skip the instalation steps but you still have to generate the project file.
Thank you very much. Learned so much.
thank you so much i really needed this
In the CRUD scaffold step, it does not create a table in the index.html.erb. Is this due to a newer version of Rails? How do I get it to create a table automatically?
I had the same issue, I had to go to 1:26:30 on the video and basically pause several times quickly to get the right formatting. I'll post it below for ease, but this is just a workaround since it's not creating the same way by default. Also, you'll need to delete the '_friend.html.erb' file in the same directory, as that is how it is formatting the data instead of using a table like the video shows. Once I deleted that file and made the changes listed below, I was able to see the same page as him. Pretty frustrating, but frustration comes with this type of thing unfortunately.
The following code between the dashed lines is what he has at 1:26:57

@@levilyon7088 Oh wow, thank you so much! I usually work in Python, so I didn't have the background in Ruby (or just Rails in general) to google this correctly.
@@levilyon7088 I'm now getting an error when trying to create a new friend saying 'Missing partial friends/_friend with {:locale=>[:en], :formats=>[:html], :variants=>[], :handlers=>[:raw, :erb, :html, :builder, :ruby, :jbuilder]}.'
never mind keeping the '_friend.html.erb' and not deleting fixed this error for me
It seemed to work for me at the time, glad you were able to figure it out!
I came here to learn rails, but now I want to learn django
ngl with the amount of praise the video gets even in recent comments, I expected something a lot more comprehensive, not to mention how the version differences made it ten times harder than it needed to be
I flabbergasted. I built a database system once and I can't belive I never used ruby on rails before.
it's fascinating how much faster using this than making it from scratch.
great video for ruby on rails beginners, Thank You
Hie.. railsinstaller.org is not working on my laptop
is railsinstaller.org down? it doesn't load :/
Its down, but, you can install ruby, then in git bash run, gem install bundler, and then run, gem install rails, and it should work for you, after that you can skip the instalation steps but you still have to generate the project file.
Great video ! This is a amazing 🔥🔥🔥
Great video!! Good as a quick refresher course for me.
UPDATES 2022:
- If you can't install gems into ruby, try doing it directly though the CMD terminal, Git Bash sometimes have problems recognizing environments and can bug really easy specially on Windows 10.
- If you are having problems with the delete button / method, try changing it to button_to and the rest of the code is almost the same as shown in the video.
- I couldn't make the delete confirmation pop-up works, if you made it work please leave on the comments how you did it.
- For those having trouble with the white background on the video: Turn On the Night Light (also known as Blue Filter) in windows 10.
To do this, just go to your desktop, right click on it and click on "Display Settings" and turn the night light on.
If it doesn't work, hit in "Night light settings" and then on: "Turn on now".
This makes the white background much more tolerable.
I finished the course and this is my review about it:
Good course, but spends a lot of time off the goal.
There's actually less than 2.3hs talking about Ruby / RoR and most of the talk is about Bootstrap or styling or git / github / heroku. So there's no point on calling these a full course about Rails.
But anyway, maybe the course is aimed for people who never programmed before, have no idea about it and just want to get their hands dirty.
I don't recommend it because there isn't too much explanation about the code and is just a "copy this and paste it here, believe me it works." and that's it.
No technical explanations or teaches what the documentation actually means. Coding is not magic or a Cook Recipe...
Could you make this ( @friend = current_user.friends.build ) work ?
Hello, first of all, thank you for this course! Really easy to understand!
I'm facing and issue and don't know yet how to solve it:
I've decided to keep a dropdown menu component in my _header. But I've realized it only work on the first interaction: After clicking on one of the dropdown item, I cannot interact with it anymore, (only after refreshing the page). It seems like it's freezing somehow
Any clue? That's the only thing I've changed (comparing to the rest of the course)
Did you sort this?
Thank you so much for the video!
Excellent tutorial, I have been looking at moving from PHP and this has convinced me. Thank you.
