Ruby on Rails Developer Resume Example + Salaries, Writing tips and Information
Before starting with this chapter, make sure your database server is up and running. Ruby on Rails recommends to create three databases - a database each for development, testing, and production environment. You should initialize all three of them and create a user and password for them with full read and write privileges. We are using the root user ID for our application. At this point, you need to let Rails know about the user name and password for the databases.
If you're used to using raw SQL to find database records, then you will generally find that there are better ways to carry out the same operations in Rails. Active Record insulates you from the need to use SQL in most cases. Regardless of which database system you're using, the Active Record method format will always be the same.
