Homework

Fri 23 Feb 2018
- Lab: File Uploads
- Lab: I18n Formatting
- Lab: Translation
  - Posted completed translation files here:https://github.com/dbierer/zf-level-2-feb-2018/tree/master/doug/module/Translation/language
  - Finished I18N + TRANSLATION labs
  - Did not finish FILE UPLOADS lab: look at onlinemarket.complete for solution
Wed 21 Feb 2018
- Lab: OAuth2
- Lab: Navigation
Tue 20 Feb 2018
- Lab: Cache
  - Make sure cache_dir is inside the options array!
  - Need to assign filesystem rights to "www-data" to the cache directory

chown www-data:vagrant /home/vagrant/Zend/workspaces/DefaultWorkspace/onlinemarket.work/data/cache

Lab: ACL
- Don't forget to check the time on your VM before setting the ACL time assertion
- Need to install the component: zendframework/zend-permissions-acl
- VERY IMPORTANT: make sure you enable rights in module/Login/config/module.config.php
- If you get stuck logged in and can't logout, wipe out the login custom identity storage:

rm /home/vagrant/Zend/workspaces/DefaultWorkspace/onlinemarket.work/data/auth/*

* Search for `//*** ACL LAB` using this command:

cd /home/vagrant/Zend/workspaces/DefaultWorkspace/onlinemarket.work
grep -rn . -e "//\*\*\* ACL"

Fri 16 Feb 2018
- Lab: AbstractRestfulController
  - Use the ListingsTable and get listings from the Online Market
Wed 14 Feb 2018
- Lab: Authentication and Password Hashing
  - Don't forget to install the zend-authentication and zend-crypt components!
  - If you get this error: Fatal error: Class 'Login\Model\AbstractModel' not found you need to add this "use" statement to the Login\Model\User class:

use Application\Model\AbstractModel;

* If you get this error: `A plugin by the name "flashMessenger" was not found` you need to install the `zend-mvc-plugin-flashmessenger` component

Lab: BlockCipher Lab
Mon 12 Feb 2018
- Lab: Listener Aggregates
Fri 9 Feb 2018
- Lab: Doctrine
- Lab: Shared Manager
Wed 7 Feb 2018
- Lab: Abstract Factories
- Lab: Delegators

Middleware

Example of simple "pipe" is in guestbook/stratigility
- Just cd to that directory and run this:

php -S localhost:8888

And then run http://localhost:8888 from your browser

Q & A

Q: How can I check if my passwords are good?
A: See: from Marcin to All Participants: in your free time you can check strenght of your password and time it takes on this site http://password-checker.online-domain-tools.com/

Errata

(PDF Page : Presentation URL: Comment)

066:http://localhost:8888/#/3/16: there is no Table Module unit!!
082:http://localhost:8888/#/3/32: to check your work:

http://onlinemarket.work/doctrine/admin
http://onlinemarket.work/doctrine/signup

088:http://localhost:8888/#/4/4: identifier of "application-identifier-database"
099:http://localhost:8888/#/4/15: has SharedEventManagerInterface been changed recently?
- Yes: it has been removed. Need to change the code on this slide to the following:

113:http://localhost:8888/#/5/9: bindRequiresDn needs an argument in the table
144:http://localhost:8888/#/5/40: the reason why we need to create a new Bcrypt() instance (instead of injecting it) is that it's a static call!
146:http://localhost:8888/#/5/42: code block runs off page in HTML (but is OK in PDF!)
159:http://localhost:8888/#/5/56: "choosig" s/b "choosing"
177:http://localhost:8888/#/5/74: missing "Lab:"
214:http://localhost:8888/#/6/34: Generate an API which draws from ListingsTable
221:http://localhost:8888/#/7/5: need to add something like this:

if ($data = $cacheService->getItem($cacheKey)) return new ViewModel(['data' => $data]);
// core logic code start
// ...
// core logic code end
return new ViewModel(['data' => $data]);

243:http://localhost:8888/#/7/27: probably could have just injected the cache-adapter: no need to inject the service manager!
256:http://localhost:8888/#/7/40: specific start/stop time should come from configuration
387:http://localhost:8888/#/9/12: "expressive of stratigility" s/be "expressive or stratigility"
425:http://localhost:8888/#/9/52: s/be Request and Response

Event Manager

Shared Manager is not automatically associated with a "local" event in ZF 3
- When creating an event manager instance, use the pre-defined Service Manager service EventManager
- This uses a pre-defined factory which injects the existing Shared Manager into the new instance
Listener Aggregate Lab
- Just have the listener log using error_log() PHP function
- Probably stick to the Events module; otherwise if you use MyDoctrine have the repository trigger
- error_log() by default goes to /var/log/apache2/error.log

Data Modeling

See: https://www.infoq.com/minibooks/domain-driven-design-quickly

Service Container

Abstract Factory

Example: see in guestbook: AuthOauth\Factory\AdapterAbstractFactory

Reflect Abstract Factory

Example: see in guestbook: module.config.php

    TableModule\Model\EventTable::class        => ReflectionBasedAbstractFactory::class,
    TableModule\Model\AttendeeTable::class     => ReflectionBasedAbstractFactory::class,
    TableModule\Model\RegistrationTable::class => ReflectionBasedAbstractFactory::class,

Config Abstract Factory

Example: see guestbook: /module/Events/config/module.config.php lines 189 and 202 - 213

Delegators

Example: see guestbook: /module/Events/config/module.config.php lines 189 and 202 - 213
Also in guestbook: \Doctrine\Factory\SignupDelegatorFactory

VM UPDATES

Error when switching locale after signing into guestbook: OpenSSL error
Guestbook and Online Market Complete both are not formatting dates & numbers based on locale
Look at the ACL for Guestbook: logged in admin but can't see Admin Area under Events
IMPORTANT please replace onlinemarket.work/module/Market/view/partials/item.phtml with this:

<?php
    $locale = \Locale::getDefault();
    switch ($locale) {

            break;
        case 'es' :
        case 'de' :
        case 'fr' :
            $code = 'EUR';

LAB NOTES

LAB: LISTENER AGGREGATE

When signing up for an event got this error:

Call to a member function filter() on null

Need to inject the events data filter into the SignupController:
- In Events\Controller\SignupController add the following:

    protected $filter;
    public function setFilter($filter)
    {
        $this->filter = $filter;
    }

* Better yet: use a trait ... because you'll need to also inject the event manager in the RegistrationTable model class.
* In `Events\Module` add `setFilter` to the factory which produces the SignupController as follow:

    Controller\SignupController::class => function ($container, $requestedName) {
        $controller = new $requestedName();
        $controller->setEventTable($container->get(Model\EventTable::class));
        $controller->setRegTable($container->get(Model\RegistrationTable::class));
        $controller->setAttendeeTable($container->get(Model\AttendeeTable::class));
        //***vvv*** ADD THIS ***vvv*****
        $controller->setFilter($container->get('events-reg-data-filter'));
        //***^^^*** ADD THIS ***^^^*****
        return $controller;
    },

AccessControl Redirect Issue

Notes

Not a fatal problem
Messes up screen redrawing
Affects:
- guestbook
- onlinemarket.work
- onlinemarket.complete

Solution

In these 3 files:
- guestbook/module/AccessControl/src/Listener/AclListenerAggregate.php:
- onlinemarket.work/module/AccessControl/src/Listener/AclListenerAggregate.php:
- onlinemarket.completemodule/AccessControl/src/Listener/AclListenerAggregate.php:
Change this:

$match->setParam('controller', self::DEFAULT_CONTROLLER);
$match->setParam('action', self::DEFAULT_ACTION);

To this:

// this does the equivalent of a forward:
$response = $e->getResponse();
$response->getHeaders()->addHeaderLine('Location', '/');
$response->setStatusCode(302);
return $response;

TRANSLATION LAB:

Need to replace the contents of the files shown here:
- onlinemarket.work/module/Translation/language/de.php

// not ready yet!

onlinemarket.work/module/Translation/language/es.php

// not ready yet!

GUESTBOOK PROJECT UPDATES:

AccessControl\Listener\AclListenerAggregate lines 59 - 60 change to this:
- From this:

$match->setParam('controller', self::DEFAULT_CONTROLLER);
$match->setParam('action', self::DEFAULT_ACTION);

To this:

// this does the equivalent of a forward:
$response = $e->getResponse();
$response->getHeaders()->addHeaderLine('Location', '/');
$response->setStatusCode(302);
return $response;
