The goal of this lab is to get comfortable performing CRUD (Create, Read, Update, Delete) actions using Active Record.
There are different ways to solve this lab so feel free to experiment!
Before starting this lab run

Try using the rake task
rake db:create_migration NAME=create_movies to create
your migration file. Once you have a migration file add columns like so:
After your migration is ready run
rake db:migrate to
migrate your table and

learn to see the tests. To make them pass open
movie_controller.rb and complete each method. It will help to open
spec/models/movie_spec.rb to see exactly what each spec is testing for.
In each method the
__ corresponds to a line of code you will need to write to
make the spec pass.
Each test will take us through performing a basic CRUD action using the database we just created. These tests will take you through:
