🏗️ Part 3 — MVC in Rails: Models, Views, Controllers Explained

Rails uses the MVC architecture:

• Model: Handles data and business logic (ActiveRecord)
• View: Template files (ERB or HAML) rendered to HTML
• Controller: The glue, handling requests and sending responses

Example controller:

class PostsController < ApplicationController  
  def index  
    @posts = Post.all  
  end  
end  

And the view:

<% @posts.each do |post| %>  
  <h2><%= post.title %></h2>  
<% end %>
