ActiveRecord Practice

Setup

1. Go to your sandbox
2. Create a new rails app: $ rails new ar-practice.
3. Create a model called Student with a name and at least two other attributes of your choice (like favorite pie and personal motto): $ rails g model student name:string other_field:type
4. Migrate your database: $ rake db:migrate

Exercise

1. Enter the rails console: $ rails console
2. Create a record in the database for yourself using new or create.
3. Create a record in the database for all the students in your pod. Ask each of them for the information you've defined for your student class.
4. If you're asking someone a question who has not yet setup their Student model, offer to help.
5. After all 5 records are created. Read about and experiment with the following ActiveRecord methods:

• find
• where
• find_by
• destroy
• where.not
