🧙 Part 4 — ActiveRecord Magic: Rails’ Powerful ORM

ActiveRecord lets you interact with the database using plain Ruby.

Example migration:

create_table :posts do |t|  
  t.string :title  
  t.text :content  
  t.timestamps  
end  

And in your model:

class Post < ApplicationRecord  
  validates :title, presence: true  
end  

Now, interact easily:

Post.create(title: "Hello Rails!", content: "First post.")  
Post.all  
Post.find(1)
