Auto code grading system like codecademy's - ruby-on-rails

I'm building a ruby on rails application with most of the views with react. I'm considering using CodeMirror as an editor for users to type in code. I want them to be able to submit the code, and the code will be run through some of my test cases and get results back, similar to how codecademy works.
What are some initial steps to achieve this?
Thank you!

Have a look at the http://reactrb.org site. There is live code editors on there. Source code for the doc site is on github.
If the code examples are in either ruby or JS you can run the test scripts in the browser (for ruby you will use opal-rspec) This makes sandboxing easy.
Sounds like a great project. If you need additional questions or help stop in at https://gitter.im/zetachang/react.rb There are a couple of people there who can help you out with the details.

Setting up ruby on rails gem ga_events

I am relatively new to web dev and I am trying to set up the ruby on rails gem ga_events (https://github.com/Nix-wie-weg/ga_events). I am doing this because I need to have google analytics event tracking within controllers and this gem seems like a good way to do it. The issue I am having is where the readme says, "After requiring ga_events.js, you have to choose an adapter." I am using Google Universal Analytics and thus I would like to choose that one. It doesn't say specifically how to do this. Where do I put that code block (https://github.com/Nix-wie-weg/ga_events#google-universal-analytics-analyticsjs)? Do I need to make a new file somewhere?
I'm assuming it's obvious for a more experienced developer. More detailed instructions+explanation would be really helpful. Thanks.
I'm using Rails 4.0.13 and Ruby 2.0.0p643.
I was having the same issue here! Turns out, it is just javascript code.
I put mine under application.js since it's a code that need to be on every page.

How to post in a blog without command prompt when using octopress in rails?

I am using octopress gem for implementing blog using ruby on rails. I got some code from
http://www.nickhammond.com/setting-octopress-jekyll-blog-rails-application/
and its work fine.
But my question is for creating a new post every time I have to write code in command prompt like
rake new_post['Hello World']
rake generate
I want something like admin panel where should be textbox, textare and submit button. and when I click on submit button it should be posted. Is it possible to create here using octopress? Please share with me, Thank you.
You're looking at a tool like this.
I haven't used it personally, but that's what I get from a simple Google search.
Personally, I'm using GitHub Pages for my Octopress stuff - I was looking for the same sorta thing you're looking for, and came across this. Obviously this is only handy if you're using GitHub for source, but you could edit your source using Prose, acting as a nice Markdown-friendly interface, and then use something like Travis-CI to compile and deploy.
I haven't set this up yet myself though, so I can't speak from experience. But I plan to. :D

making a installer in rails

I have been working on this, very, small photo cms lately. And now i ready for setting it up to Github. So i will love to have some kind of installer, just as much for leaning it, I'm thinking something like you type a command and then it starts by copy all the files to the rails app, and then asking you for what your flickr_id is etc..
So i have to store all this information and call it down.. i.e if i should show some pictures, i have to use the flickr_id.
Hope you understood my question..
You can start by using rails-app-installer, it's not maintain completly but can works. It's use on the Typo project

Well built rails code for download

I want to get into rails by examining well built code
where can i find typical open source rails project that i can download
and learn from ?
i'm interested in facebook connect integration (facebooker), tag clouds, searching in
my website
I'm not looking not tutorials or screen casts
Thanks!
This question gives a good list
a list of projects with good test-suites
a list of open source rails apps to learn from
Have a browse of ruby tool box and download some open source. For example there's refinery and zena, two content management systems and Rboard, a forum. Depends what you want really but there's plenty out there. Ruby toolbox entries are ordered by github watchers and forks to give you an idea of their popularity.
I really like looking at the commits in teambox.
I find it a bit more complicated. But there's also spree.
There's also devise which is really interesting to look at too.
Finally, I'd recommend you to follow the rails commits (it's the only commits feed I have in my Google Reader).
Gady, this is an extremely rich topic you're asking about and resources are all over the internet. Try starting at http://rubyonrails.org/.
You should be able to find tens of questions just like yours (asked and answered) by searching SO at the top bar.
For Rails, part of it is the building process, so one feasible approach is to read a tutorial like http://railstutorial.org/book
then when in Chapter 2, you will use Scaffold, and at that time, you will have some basic code to look into how a basic Rails app is.
I also suggest you use source control like Git, Mercurial, or SVN to commit different phases of the project, from creating the rails project and then after each step, so you can diff what the changes are during each step.
If you already have Ruby 1.9.2, Rails 3.0.1, and sqlite3, then you can
rails new myproj
cd myproj
rails generate scaffold foo name:string salary:integer gpa:float note:text
rake db:migrate
rails server
and now you can use http://localhost:3000/foos to create, display, update, delete the foo records, and have quite a bit of source code to look at. Most of the customizable code is in app, with css and javascript in the public folder.
Ryan Bates has an excellent series of videos.
http://railscasts.com/
An extremely valuable resource.
Radiant is a CMS that you can download for free and see how it works. It is a great piece of code to look at and see how it works.
I guess that most open source Rails projects are shared on Github, so it may be interesting to browse its Ruby section and look for most watched or most forked projects:
http://github.com/languages/Ruby
Steady stream of new interesting projects to take a look at :)
And don't forget the official:
guides.rubyonrails.org
well there is one "bigger" project on github, waiting for downloading and contribution...
but it's a little controversial because of the security issued they have (had?)
It's still worth a look:

tips and tricks for using vim with ruby/ruby on rails

I'm one of those developers who isn't using TextMate with any of his Ruby/Ruby on Rails work. My particular loyalty in this arena lies with vim. What are your favorite tips/tricks for using vim with Ruby and/or Ruby on Rails to make you as efficient as possible when working?
Most important
Get a copy of rails.vim it is awesome on millions of levels. Read the doc. There are way too many tips, :Rview customer, :RSmodel foo, :Rinvert, gf, :Rextract, :Rake and the list goes on and on. You will probably want NERDTree as well for easy navigation (which you can access using :Rtree)
Second most important
Follow tpope on twitter (the author of fugative, rails.vim, haml.vim, vividchalk theme, cucumber.vim and so on), he seems to be posting new related to Rails vim plugins quite regularly (be it syntax highlighting or git integration).
You might want to checkout my ruby/rails specific vimfiles.
Its a useful starting point and has many useful Ruby/Rails plugins bundled and configured.
The one thing that really sucks about Textmate is that it doesn't run on Linux. My vim/gvim config is the same on Mac, Windows and Linux. Same fonts, same themes, same plugins and same customizations.
I mostly use Textmate for snippets and quick evaluations for posting here.
I wrote an in depth guide on using Textmate features (especially Rails related features) in VIM. It's very relevant to this question.
http://www.jackkinsella.ie/2011/09/05/textmate-to-vim.html
I don't use vim, instead, I'm like those millions of developers using Textmate. Nevertheless, a colleague does use vim/gvim.
By looking at him work, one of the things I wish I could do in Textmate is the ease of working on multiple files at the same time. Basically, you can easily manipulate multiple windows, which is quite handy.
