How much Ruby do I need to learn before moving into Rails?

If you know other programming languages, especially object oriented ones, I'd recommend spending a couple days on Ruby. Line between Rails and Ruby is kinda blurry

* Have a look at the syntax: https://learnxinyminutes.com/docs/ruby/

* Work through the Ruby koans: https://github.com/edgecase/ruby_koans

* If you have time or desire, look through the Poignant's Guide to Ruby: https://poignant.guide

It is a wonderful language. Good luck.

Not much, I actually learnt RoR before I got into Ruby. The basic syntax is simple and you don’t need much Ruby magic to get a typical CRUD app up and running in RoR.

I learned both Ruby and RoR simultaneously on the job and somehow managed to avoid the pitfall of confusing the two. Maybe it's my interest in languages that makes me look at the note on the doc page that indicates it part of ActiveSomethingOrOther vs Ruby since version x.

I don't know if it will matter for you, but I've found it useful to know what it is that I know. If this seems like you then pay attention to those notes whenever you see them mentioned. I don't specifically look for it but if mentioned on a doc page or StackOverflow comment will pick up on it.

Try ruby kickstart, CS puzzles introducing you to the language. Fun and addictive, will bring you up to speed in less than a week.

I dove into Rails before really learning Ruby. Agree with other commenters - if you have exp with other languages, take a little time to recognize the nomenclature:

This guide is enough, and it's an excellent primer: https://pine.fm/LearnToProgram/

You don’t really need to know any Ruby to do Rails. It’s so much it’s own ecosystem that you’ll end up learning Rails-flavored Ruby no matter what you do.

That being said, vanilla Ruby is a real joy and you’ll be a better developer if you do take the time to learn it deeply. One fun source of lessons is Ruby Tapas, which is a subscription video “channel” that presents tons of best practices and neat tricks in short ~5’ videos. I highly recommend subscribing for a month and plowing through the back catalog :)

I'd recommend to get some confidence with Ruby before moving to Rails. It's better to spend 2-3 months learning Ruby and then focus on learning Rails, than struggle with both right from the start.

When people say that you can learn only basics of Ruby in few days and then move to Rails, they are right, you can, but this way you will learn two things in parallel, and it's pretty exhausting. So this doubtfully will save you any time.

I learned them together as my first web development lang/framework, coming from C for microprocessors.

I used the excellent Rails Tutorial [0] by Hartl.

Just look up things you don't know/understand as you go - he also introduces Ruby in chapter 4 though, so you should be fine.

I think you can just dive in personally. If you want some prep work, read through Why's Poignant Guide to Ruby to grasp the basics.
