Rails is awesome. There's absolutely no doubt about it, that's why we work with it. But for someone coming from a non development background there can be a lot of learning to get through. As someone who knows how hard it is, I've compiled a list of tips and resources to help you out.
Buy a book
Agile Web Development with Rails is pretty much the definitive book to start with. After giving you an intro to the MVC way of thinking it leads you through building a small web shop application, with the last half of the book going more in-depth to the different parts of Rails such as ActiveRecord, ActiveSupport, etc.
Building something in Rails to serve a few views, show records, etc isn't hard. You can do it in a few minutes. Build something simple to wrap your head around where the magic starts and stops and how you can use it (more on the magic in a bit). A simple blogging engine is always the easiest place to start, and it allows you to get used to the MVC way of thinking and how it all fits together.
Learn the magic
When discussing Rails development with someone who knows what they're talking about, you might hear about the word abstraction. From Wiktionary:
Any generalization technique that ignores or hides details to capture some kind of commonality between different instances for the purpose of controlling the intellectual complexity of engineered systems, particularly software systems.
In other words, magic. In Rails specifically, it can happen in a lot of places. For example, when you generate your first scaffold for your post model in your blog application and take a look through the views, you'll see things such as
<%= link_to 'Show', post %> and
<%= link_to 'Edit', edit_post_path(post) >. If you take a look in your routes you will the scaffold generator has added
resources :posts. This is the snippet that allows Rails to build these links for us. This was one of the things that took me a while to learn, but when it clicked a lot of stuff made sense.
Ask someone or look it up
Having someone to
Good luck kid, you'll need it
Hopefully these give you a good basis to get started with Rails, feel free to shoot a quick question to us if you want to know any more. In the meantime, go have a look at all things I mentioned and start learning.
