Active Record

É um design pattern que o Rails implementa a partir da gem ActiveRecord.

Serve para conectar a camada Model da aplicação com tabelas do database, para assim criar um modelo de domínio persistível, onde a lógica (Model) e dados (BD) são apresentados em uma única solução.

Já persiste no BD:

obj.create

INSERT GRAPHIC HERE (include hyperlink in image)

Repository Title Goes Here

Subtitle or Short Description Goes Here

Project Title

One Paragraph of project description goes here

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.

Prerequisites

Revert the full commit

Sometimes you may want to undo a whole commit with all changes. Instead of going through all the changes manually, you can simply tell git to revert a commit, which does not even have to be the last one. Reverting a commit means to create a new commit that undoes all changes that were made in the bad commit. Just like above, the bad commit remains there, but it no longer affects the the current master and any future commits on top of it.

git revert {commit_id}'

About History Rewriting

Delete the last commit

Deleting the last commit is the easiest case. Let's say we have a remote origin with branch master that currently points to commit dd61ab32. We want to remove the top commit. Translated to git terminology, we want to force the master branch of the origin remote repository to the parent of dd61ab32:
