📦 Rails Models

🧱 What Are Models?

• Ruby classes that represent DB table rows.
• Inherit from ApplicationRecord → ActiveRecord::Base
• Dynamically map DB columns as attributes.

🛠️ Create Task Model (Manual)

touch app/models/task.rb

# app/models/task.rb
class Task < ApplicationRecord
end

🔁 Table ↔ Model Mapping

• Task model → tasks table
• Task.new → a row in tasks
• title attribute ↔ title column

🚀 Auto Generate Model + Migration

bundle exec rails generate model Task title:string

bundle exec rails generate model <ModelName> <field:type> <field:type> ...

⚠️ Will error if model or migration already exists.
