Ask HN: how to Learn MVC?

1 points by shire 13y ago

I'm learning Python and Django but I need to grasp this MVC pattern stuff. Any good books or screencasts explaining how MVC works? I'm a beginner so a basic explanation would be appreciated.

Check out this Rails MVC pattern (http://addyosmani.github.io/backbone-fundamentals/#mvc-applied-to-the-web http://addyosmani.github.io/backbone-fundamentals/#mvc-appli...) explained by Addy Osmani for developing Backbone Apps. Rails MVC is said to be very similar to Django MVC, so this should be pretty useful.

  I'm not really sure that that book is good for Django MVC or even rails since Backbone MVC is a little different and some consider it to be a MV*.

    Don't read the whole book. Just the Rails MVC pattern section I linked you.

a primer on mvc ill just give a easy to understand (?) example MVC Model View Controller Model: this is a data model [access pattern] models/users.code: class User { function getUsers() { $db->fetchAll("SELECT * FROM USERS LEFT JOIN CRAZYTABLE ON CRAZYSTUFf = 1") } } Controller: Handles application logic controllers/userlist.code requires('models/user.code') function showUsers() { $users = User::getUsers() $usernames = [] foreach($users as $row) $usernames[] = $row['name'] renderView('views/userpage.html', $usernames) return } View: Display logic, ideally as simple as possible Could be a html template or a windows form Purists say you should do all data validation and preperation in the controller views/userpage.html <div id=myuserlist> <h1>Our users</h1> <ul> {{ foreach $users as $user }} <li>{{ $user }}</li> {{ endforeach }} </ul> </div> Now you understand MVC! =)
