Try Yii2 in one click with Vagrant VM + Ansible provisioning

See all details in my previous post.. All software you wanted to try with Yii2 installed and provisioned out of the box.
In two words :
"Try Yii2" provides you with Vagrant file and Ansible provsioning scripts. Vagrant will launch the VirtualBox VM, download OS image, deploy it and then run Ansible. It will set up all needed software inside Linux VM, clone Yii2 project, download test DB and connect it with project. Also Vagrant will modify you hosts file and assign special local domain adresses with VM IP address, so you will be able to access test Yii2 prject by humanreadable local domain name. All these steps will be made completely automatically, just run vagrant up and wait !

Yii2 Tips & Tricks

• How to use yii2-authclient to communicate with Twitter using Single Access Token

• How to change server address of the asset files being delivered ?

  You should configure AssetBundle::baseUrl which may contain the host info you need.

• How to Input array for Active Fields ?

  $form->field($model, 'uploadFile[]')->fileInput('multiple'=>'multiple');

• How to override Error Handler

$handler = new \app\components\ApiErrorHandler;
        \Yii::$app->set('errorHandler', $handler);
        $handler->register();

• Is there an alternative for findByPk from Yii1 ?

  Here is code example https://github.com/yiisoft/yii2/issues/3390

• Making REST API with Mongodb (as IDs are not Integer)

'rules' => [
       [ 
                   'class' => 'yii\rest\UrlRule',
                   'controller' => 'user', 
                   'tokens' => ['{id}' => '<id:[a-z0-9]*>']
                   ],
          ],

• How can i pass params for layout for breadcrumbs?

  In controller: $this->view->params['breadcrumbs'] = [...]; In view: print_r($this->params['breadcrumbs']);

• How do i include image file using assets?

  After you call $bundle = YourAssetBundle::register($this);, you can use $bundle->baseUrl and prefix it to the image path in the image tag. Yii won't do automatic replacement like you said. Unless you are developing an extension, you normally don't need to put images in an asset bundle. You should directly put them under Web accessible folders.
