Ruby on Rails 8

Core lectures on Ruby on Rails

From what happens after you press Enter in the browser to your first working application. Every lecture has text and video, all in Russian. Lectures are sold separately or as a bundle, start with any of them.

🇷🇺 In Russian Save $13.92

Full bundle

All lectures of the Rails course

The whole course in one order: from the path of a request to a working application. Cheaper than buying lectures one by one.

All 8 lectures, text and video, in Russian
≈ 6 h of video
Instead of ~~$63.92~~ for $50

🇷🇺 In Russian Lecture 1

The path of a request, from browser to server

Domains, DNS, hosting, Docker and the local environment

What really happens between pressing Enter and the site appearing. The foundation without which Rails stays magic.

Browser, ISP, domains and DNS
Registrars, hosting and the hosts file
Why a developer needs Docker and containers

🇷🇺 In Russian Lecture 2

The chain of web servers

Rack, Puma, Nginx and HTTPS

Why one web server is not enough and how they work together. A simple model you can keep in your head.

Rack as the common interface
Puma and Nginx: who does what
Why a modern site needs HTTPS

🇷🇺 In Russian Lecture 3

Ruby on Rails initialization

From config.ru to routes

How Rails boots from the inside. Knowing the initialization points turns non-standard tasks from a problem into routine.

config.ru, boot.rb, application.rb
Custom directories and project structure
What happens before the first request

🇷🇺 In Russian Lecture 4

Rails as a process

The RCAPMV scheme, seven stages of request handling

MVC does not explain how an application works. A seven-stage scheme, from route to response, does.

Routing, Controller, Before actions, Action
Parameters, Model, View
How the stages map to project files

🇷🇺 In Russian Lecture 5.1

The development environment

RailsStart, Docker and Dev Containers

Models, migrations and AI assistants

Database schema through a dialogue with AI
has_many and belongs_to relations
Two models and deliberate simplification

🇷🇺 In Russian Lecture 5.3

Migrations, seeds and Rails Console

Test data and working with the database

From a migration file to live data in the database. Seeds, Faker and the console as a working tool.

Where the Rails database lives
Seeds and data generation with Faker
Rails Console: exploring models by hand

🇷🇺 In Russian Lecture 5.4
