Introduction

Some notes on syntax on models always looking up.

Foreign Keys

Optional

• Change Migration to null: true e.g. t.references :vehicle, null: true, foreign_key: true
• add optional: true to model e.g. belongs_to :vehicle, optional: true

Key Name different that table Name

e.g. key is driver_id table is employee

• Change Migration so foreign_key is explict to table e.g. foreign_key: { to_table: :employees }
• Change Model to define class e.g. , class_name: "Employee"
