##Installation

The preferred way to install this extension is through composer.

##Demo

Once the extension is installed, simply modify your application configuration as follows:

return [
    'bootstrap' => ['simplechat'],
    'modules' => [
        'simplechat' => [
            'class' => 'bubasuma\simplechat\Module',
        ],
        // ...

Use the same configuration for your console application:

Note: You need this configuration to access simple chat via command line. You can remove it in production mode.

You can access Simple Chat via command line as follows:

php yii simplechat/start

# unload fixtures
php yii simplechat/clean

# unload fixtures and load them again
php yii simplechat/reset

# unload fixtures and drop test tables

You can specify different options of the start and reset command:

# You can specify how many fixtures per user and message you need by the --users and --messages options
php yii simplechat/start --users=50 --messages=10000
php yii simplechat/reset --users=20 --messages=5000

# You can specify in what language to generate fixtures by the --language option. Thanks to yii2-faker
php yii simplechat/start --language="ru_RU"
php yii simplechat/reset --language="fr_FR"

You can then access Simple Chat through the following URL:

Extend the main conversation class like follow:

namespace common\models;

use common\models\User;
//...

class Conversation extends \bubasuma\simplechat\db\Conversation
{
    public function getContact()
    {
        return $this->hasOne(User::className(), ['id' => 'contact_id']);
    }
    
    /**
     * @inheritDoc
     */
    protected static function baseQuery($userId)
    {
        return parent::baseQuery($userId) ->with(['contact.profile']);
    }
    
    /**
     * @inheritDoc
     */
    public function fields()
    {
        return [
            //...
            'contact' => function ($model) {
                return $model['contact'];
            },
            'deleteUrl',
            'readUrl',
            'unreadUrl',
            //...
        ];
    }
}

Extend the main message class like follow:

namespace common\models;

//...

class Message extends \bubasuma\simplechat\db\Message
{
    /**
     * @inheritDoc
     */
    public function fields()
    {
        return [
            //...
            'text',
            'date' => 'created_at',
            //...
        ];
    }
}

Create a controller like follow:

namespace frontend\controllers;

//...
use yii\web\Controller;
use common\models\Conversation;
use common\models\Message;
use bubasuma\simplechat\controllers\ControllerTrait;
//...

class MessageController extends Controller
{
    use ControllerTrait;
    
    /**
     * @return string
     */
    public function getMessageClass()
    {
        return Message::className();
    }

    /**
     * @return string
     */
    public function getConversationClass()
    {
        return Conversation::className();
    }
}

Note: If you are using this extension in your frontend application, you can find the usage of widgets in index.twig.

##FAQ Does this extension work with any template engines other than twig?

Yes. Given that, the default render in yii2 is php, you must indicate explicitly the extension part in view names.

Can I use this extension in a RESTful APIs?

Yes, You can.

Can I use different template engines for rendering in server side and client side?

Yes. But using the same template in both sides remains the best implementation.
