The blog directory will have a number of generated files and folders that makeup the structure of a Rails application. Most of the work in this tutorial willhappen in the app folder, but here's a basic rundown on the function of eachof the files and folders that Rails creates by default:
Ruby On Rails Tutorial
JavaScript asset compression requires youhave a JavaScript runtime available on your system, in the absenceof a runtime you will see an execjs error during asset compression.Usually macOS and Windows come with a JavaScript runtime installed.therubyrhino is the recommended runtime for JRuby users and is added bydefault to the Gemfile in apps generated under JRuby. You can investigateall the supported runtimes at ExecJS.
Inside the block for create_table, two columns are defined: title andbody. These were added by the generator because we included them in ourgenerate command (bin/rails generate model Article title:string body:text).
To choose the status for the existing articles and comments you can add a default value to the generated migration files by adding the default: "public" option and launch the migrations again. You can also call in a rails console Article.update_all(status: "public") and Comment.update_all(status: "public").
Hello devs! I'm a frontend developer, now I need to work on a rail project and I don't know ruby and ruby on rails, I didn't have time to practice and learn in a month. I need resources to learn it fast.
By Domantas GThere are plenty tutorials online which show how to create your first app. This tutorial will go a step further and explain line-by-line how to create a more complex Ruby On Rails application. Throughout the whole tutorial, I will...

The Ruby on Rails Tutorial takes an integrated approach to web development by building three example applications of increasing sophistication, starting with a minimal hello app, a slightly more capable toy app, and a real sample app. The emphasis throughout the tutorial is on general principles, so you will have a solid foundation no matter what kinds of web applications you want to build.
I just meant to tell you: your tutorial books from the Learn Enough series are awesome! The books are well-written, clear, concise, super-useful, and even fun to read. Thank you so, so much for this! I have bought the first three and will buy whatever you publish next. Keep up doing this very good work and thanks again.
I will try to explain every line of code and how I came up with the solutions. I think it is entirely possible for a total beginner to complete this guide. But keep in mind that this tutorial covers some topics which are beyond the basics.
So I switched to a virtual machine instead. I chose to use Vagrant to create a development environment and PuTTY to connect to a virtual machine. If you want to use Vagrant too, this is the tutorial which I found useful.
If you are still running the application, restart the Rails server to make sure that new gems are available. To restart the server simply shutdown it by pressing Ctrl + C and run rails s command again to boot the server.
It renders the requested template. To use ruby syntax inside the HTML file, we have to wrap it around with (embedded ruby allows us to do that). To quickly learn the differences between ERB syntax, checkout this StackOverflow answer.
Phoenix on Rails is a 59-lesson written tutorial that teaches Elixir, Phoenix and LiveView from scratch to developers who already have experience with Ruby on Rails. The course is designed to leverage your existing knowledge of Rails to accelerate your learning of Elixir and Phoenix.
Even if the text is the same between your view and your test, if you copy/paste from the Rails tutorial, you should re-write the text between title tags in your view (Home, About, Help, etc) yourself and the text should pass. Hope this help, it passed for me with this.
It turned out to be a simple typo in static_pages/home(about & help).html.erbI had misspelt "Tutorial" and copied pasted the same mistake into each html.erb. Corrected typo and re-ran rails test.Success :)
Beware, the rails world is a massively frustrating mess of outdated and inconsistent documentation and examples. It is maybe one of the fastest moving and most faddish development communities there is. By the time you learn something it will already have changed. Even the books are not consistent in which version of rails they are talking about. Documentation by blogging! enough said.
I currently do RoR on windows. My advice is to avoid windows if you can. Lots of things don't work and the rails community really really doesn't care about you. The move to Git has really messed me up since it doesn't work very well on windows. A lot of gems will fail because of this (Heroku looks like a cool tool - too bad for me it can't handle window's Git setup). Capistrano is out. It goes on and annoyingly on.
Plus, in the back of your mind, you always wonder when something doesn't work "Is it a rails/windows problem?" I am not sure this is solved by using linux because linux brings its own hassles like constantly having to upgrade all those different dependencies, etc...If that's the kind of thing you enjoy it might be an okay choice for you. Those days of enjoying system fiddling are behind me and I just want to get on with doing my work. I am planning on installing ubuntu on a home machine just so i can get familiar with things like capistrano so maybe my opinion will change.
I'd highly suggest if you are going to do rails dev for any amount of time you seriously consider getting a Mac. If you value your time and sanity it will pay for itself almost instantly. Depending on how you value your time 10 hours of debugging windows/linux setup problems and you have spend as much as a Mac costs anyway.
Rails is a joy compared to what it replaces but it is a bit of a pain in that its proponents skip right past a lot of the boring but important stuff like documentation, compatibility issues and community building. It is way more powerful than other frameworks like Django but I sometimes look over at the Django documentation and community and sigh like a guy with a wild sexy girlfriend looking at his friend's plain but sane and stable wife. But then rails adds a feature and I go "Ohhh shiny!"
Aside from books the most important thing is to get feedback on what you are doing. To do this I recommend spending time in irc.freenode.net #ruby and #rubyonrails. It is also extremely helpful to post things you are working on or having trouble with here on stackoverflow as the comments, explanations and different way of thinking about things that people provide are invaluable.
0) LEARN RUBY FIRST. This is very important. One huge advantage of Rails is Ruby: a great language that is very powerful but also marvelously easy to misunderstand. Run through a few Ruby tutorials online. When coding challenges come up on Daily WTF, write them in Ruby. You'll pick it up fast.
After the guide, I'd recommend either one of the books the others have suggested, or following the series of screencasts at Learning Rails which is how I picked up enough Ruby on Rails to be dangerous. Once you've completed the Learning Rails series. what you want to do with Rails will start to diverge from the general tutorials and that's where Railscasts becomes a wonderful tool. There's not much can be done with Rails that Railscasts hasn't touched on at some point.
I came from a Java background to Ruby to. I found this tutorial helpful -lang.org/en/documentation/ruby-from-other-languages/to-ruby-from-java/. When it comes to learning rails I cannot say how much I use script\console. It allows you to play with the code and learn how to do things that you are not sure about.
The only book I ever bought was Agile Web Development with Rails, Third Edition -web-development-with-rails-third-edition. It was quite useful and provided a good overview of the Rails framework. In addition to that I regular watch Railscasts( ), which is a great screen casting blog that covers all kinds of Rails topics.
I use netbeans for my IDE and occasionally vim (with the rails plugin). I like netbeans but, I find that it can still be a little flaky when it comes to the Rails support (not all the features work all the time).
I come from a non-programming background. I have learned PHP on my own and recently joined a firm that specializes in Ruby on Rails. They have a comprehensive Rails training program, which is flexible enough to accommodate whatever changes we want to implement. Though I am not a rails pro, I would like to share my experience with rails. I hope that it helps.
recently started the RoRTute by Michael Hartl, getting stuck trying my first rspec test in section 3.2, at this point the test is meant to fail but all i get are errors which I'm having a hard time interpreting. I've had a look around but not getting much luck finding a similar error and/or solution. I am brand new to programming and ruby/rails. Any help would be greatly appreciated, thank you!
I went through the entirety of the Ruby on Rails tutorial for the blog application here. In this blogging application there are 2 models articles and comments. Comments belong to the articles model. However, the problem that I seem to be having is that my comments do not seem to be showing up in my show view from my article_controller.rb but everything else seems to be. I am still pretty new to rails but does anything stick out from the files shown below?
