Realizing that a lot of Rails developers get in trouble because a shallow knowledge about Active Record patterns, I decided to create a series of courses, with total focus in the Model part of MVC. Different than conventional courses, where you develop a project and learn according to the lessons's context, we'll go deep into Active Record concepts and apply them in pratical examples.

The idea behind of this series is to lead you to the next level of Active Record and masterize the Model part of MVC(which is in my opinion the base to develop well done back ends).

These courses can be a first step to learn Rails too, I'm sure after learning deep how models works, it'll be easier to understand how the framework works.

In this first course you're gonna learn:

- Basics concepts to work properly with Active Record

- CRUD with Active Record

- Transactions and Database Locking(Bônus)

- Queries(The most important content of this first course)
