Transcript

1. CakePHP 3.0 The cake isn't a lie and it tastes delicious Justin Yost Web Developer at Loadsys
2. What is CakePHP • MVC Driven OO PHP Framework • Heavily focused on Conventions over Configuration • CakePHP will be 10 years old in May(ish)
3. Goodies in CakePHP • Limited to no configuration needed to get running • Most everything you need is built in • Super easy to rip out anything you dislike and replace with your own (this wasn't always true)
4. Changes in CakePHP 3.0 • Follows PSR-4 and PSR-2 (which means also PSR-1) standards • Composer is the only supported way to install CakePHP • Namespaces • Heavy focus on making the CakePHP Core even more extensible and decoupled • Getting rid of the cruft that has built up over the years
5. Changes in CakePHP 3.0 • Brand new ORM with tons of cool features • Routing improved and made much faster and simpler • HTTP Classes rewritten to focus on modern HTTP world (dealing with PHP Streams, OAuth, etc) • Throwing out the idea that CakePHP does things in it's own weird way for some common problems (Aura.Intl for example)
6. How do I use CakePHP 3.0? • Current release is the 1st RC (released Jan. 2, 2015) composer create-project --prefer-dist -s dev cakephp/app [app_name]
7. CakePHP - Bake • Bake is CakePHP's way of generating the basic Model, View, Controller layer given a database schema • So I've loaded a database schema in here already for a simple bookmark system, that is provided from CakePHP's documemation bin/cake bake all users bin/cake bake all bookmarks bin/cake bake all tags
8. So what do we have? • http://vagrant.dev:8080/
9. Password Hashing • src/Model/Entity/User.php
10. Find Bookmarks matching a tag • config/routes.php • src/Controller/BookmarksController.php • src/Model/Table/BookmarksTable.php • src/Template/Bookmarks/tags.ctp
11. Let's talk about the new ORM • There are now two primary Objects in the ORM: • Tables: "These objects provide access to collections of data. They allow you to save new records, modify/delete existing ones, define relations, and perform bulk operations." • Entities: "Entities represent individual records and allow you to define row/record level behavior & functionality."
12. Bad things Pre 3.0 • Results were arrays not objects • Couldn't stack model/database calls • No query object (sub-queries/unions were hard in Cake's ORM) • No attaching a method to happen on adding/editing/ returning a field in a database, only attaching at the overall Model level • Other issues
13. So what's cool about the new version? • Make everything return query objects and stack at will
14. Example: • src/Controller/BookmarksController.php
15. So you can stack something like? Students are allowed to retake their lowest quiz grade within the last 14 days iff it is above a 50% $this->Grades->find('students')->find('quiz')->find('date_range')->find('lowest')->find('above50')
16. That's the biggest change in Cake 3.0 • Everything else is secondary to the ORM if you have used Cake before hand
17. Personal history with CakePHP • I learned it back in the 1.2 era (2008-ish) and haven't really left it since then • Cake 2.x era has been great for the CakePHP community • Cake 2.x has rarely felt like I was missing something or the framework was preventing me from doing something • Cake 3.x gets rid of pretty much every negative association you could have had with CakePHP from the past and gives you a whole new underlying core without a hard transition
