Minimum for Junior RoR?

Question

Ruby on Rails

Tell me the minimum knowledge that a solid Junior RoR should have.
And in addition:
1) What books to read besides Hartle?
2) Where can I read good tutorials / articles?
3) There is a lot of old information on the Internet. How can you tell what is current from what is outdated? Is it painful to switch from version 3 to version 4 of rails?

In addition to the link above:
1. Rails 4. Agile development of web applications
(I often turn to Chapter 3 if I have questions)
2. Articles and website (also on Russian ) cover almost all questions that arise at the beginning. Going deeper , we often go to apidock.com/rails and api.rubyonrails.org
3. At 100% of these screencasts , there are only 1-2% of syntax inconsistencies.
4. Also, if you are a resident of St. Petersburg (or plan to move), you can sign up for this excellent course on RoR , if from another city, then here is a great platform for learning.
ps:
Don't forget about Convention over configuration - https://github.com/styleguide/ruby
Also , don't forget that Rails is Ruby - Chris Pine - "Learn to Program"

There is no specific list. In one place of work, a good knowledge of one may be strongly needed, in another place - another. Server web development is huge. That is why a junior needs to have a wide range of knowledge and be able to navigate new gems, technologies, and approaches. I would say that the most important thing is to be able to search for the necessary information and quickly master the new.
I think the best way to learn Rails development and get a job is to take a course at www.thinknetica.com/. But you'll have to work hard :) This course is the best that exists in RuNet, and, probably, on the entire Internet. Not taking advantage of this opportunity is simply stupid.
1) Any books on Rails and (which is also extremely important) Ruby.
2) Subscribe to the newsletterrubyweekly.com
3) The most noticeable sign of legacy code is the use of the old hash syntax:
:a => 1, вместо a: 1(except when the hash key is not a character).
Moving from 3 Rails to 4 Rails is not difficult, but depends on application size and test coverage. It is better to learn 4 right away (and 5 is already on the way).

Answer 3

onrails.club/t/put-v-junior-ror-ruby-razrabotchiki/61 they wrote something here, read it

Answer 4

1) Documentation
2) There are many interesting videos on railscasts.com
3) Rails 4. Painless: there are many differences, but they are all simple. There are transition materials.
You need to be able to work with rails, the most popular bundles, be able to write tests. Be able to develop simple sites (toaster level). That's enough for the junior level.

Answer 5

RoR-non-RoR often doesn't matter. Here is an approximate theoretical minimum for a programmer , as you can do it, you can do roar.
