Passo [01] Rails New

Agora que ja temos todo o ambiente de desenvolvimento Ruby e RoR instalado e configurado, vamos criar o nosso CRM. Abra o seu Terminal e navegue até a sua pasta preferida para trabalho:

$ cd ~/Workspace

Execute o gerador de aplicação:

$ rails new crmapp

O output deste comando é extenso:

Agora temos uma estrutura pronta para trabalhar, entre na pasta criada:

$ cd crmapp

Vamos dar uma olhada na estrutura criada pelo gerador do Rails, abra o seu editor:

$ redcar .

Estrutura de Pastas

Durante o curso iremos nos focar apenas 3 pastas:

app;
config;
db;

App

Esta é a pasta que contém a aplicação em si, as Views, Modelos e Controllers, além de Assets, Helpers e Mailers. Neste Curso, iremos manter o foco no primeiro grupo
