Introduction to Persistence with Ruby on Rails

Want to see Rails in action? Join us for a 45-minute session.
We’ll build on top of Threadly, a simple HTML, CSS, and jQuery App from Codecademy Pro. We’ll show you how to use Ruby on Rails to add data persistence to the app – making it possible to save and access data even after you refresh a page.

If you want to follow along, we recommend you:

Grande work here. Thank you for having such progressions, and stamina. Nice work, i think these are the processes successful people will use when their time comes. For myself, i am going to continue code academy practices and see what i can do to make progress to follow more people like Yourself on Github.

In the app folder edit the Gemfile file and add: gem 'coffee-script-source', '1.8.0', then run in terminal: bundle install, run rails server(if error also run bundle update coffee-script-source). If you modified 'application' to 'default', you can change it back now. Worked for me on Win10.

After creating the index.html.erb, the server gives an error

ExecJS::ProgramError in Posts#index

TypeError: Object doesn't support this property or method

Everything works for me except the appearance of the Post button. All the other styling works; the font, the form transition, even the pointer hover on the button, but the button color didn't change. I copied straight from my style.css file from the last project... anyone have any ideas?

How would you add this to a website (via FTP)? When I try to go to the page on my website, it gives me a 404.3 Error.

somehow my t.string :comment shows as not defined. I get a noMethodError in Posts#index saying undefined method 'comment'.

Can anyone help me fix it?

My code looks the same compared to the github source but after adding the ruby code for input and submit in the view I get message "The action show could not be found for postscontroller". Help...?

[ameersaleem]

I'm a little confused. Do you have to install Ruby on Rails every time you use it? I don't know how to create the new terminal without reinstallation (or maybe I've missed something?)

[marc_so]

is there a way to redo courses without making a new account ?
