What is j-Eloquent?

Thanks to Laravel, Django and Rails we all know that convention over configuration (CoC) makes the development more funny. So suppose that you want to convert the Gregorian date attributes of your Eloquent models to Jalali (persian) dates, in this case j-Eloquent helps you to convert them conventionally, for example when you access a property named $model->jalali_created_at on your model, the PersianDateTrait detects the convention automatically and tries to convert created_at property of your model if it is a date attribute. This is also true for $model->toJson(); and $model->toArray(); fields.

Installation

require following line in your composer require secion :

	"require" : {
			// Other dependecies ,
			"bigsinoos/j-eloquent" : "dev-master" // Laravel 5 , "1.0" for Laravel 4
	}

Requirement

this package requires : miladr/jalali

Features

• Coneventionally converts Eloquent model date attributes to Jalali date when the original date attribute is accessed prefixed by a string like jalali_.
• Automatically converts date attributes to Jalali dates when model's toArrayl, __toString(); and toJson are called.
• Custom date formats can be set for dates.

Documentation

The PersianDateTrait :

By using \Bigsinoos\JEloquent\PersianDateTrait trait in your models you can enable the plugin :

<?php

class Role extends \Eloquent {
    use \Bigsinoos\JEloquent\PersianDateTrait;
    protected $table = 'roles';
}

Usage

By default you can access your eloquent date attributes in jalali date by adding a jalali_ substring to the begining of your original attribute like jalali_created_at :

    $userPremiumRole = Auth::user()->roles()->where('type', 'premium');
    $userPremiumRole->create_at; // 2014/12/30 22:12:34
    $userPremiumRole->jalali_created_at; // 93/09/08

Changing jalali_ prefix

You can change the jalali date convention prefix with overriding $model->setJalaliFormat($format) and $model->getJalaliFormat(); or by overrriding $model->jalaliDateFormat property on your model class :

class Role extends \Eloquent {

    use \Bigsinoos\JEloquent\PersianDateTrait;

    protected $jalaliDateFormat = 'l j F Y H:i';
}

# or

class Role extends \Eloquent {
    
    use \Bigsinoos\JEloquent\PersianDateTrait;
    
    public function setJalaliFormat($format){
        // do custom things here
        $this->jalaliDateFormat = $format; return $this;
    }
    
    protected function getJalaliFormat()
    {
        // return any format you want
        return 'l j F Y H:i';
    }

}

Custom date attributes :

You can tell Eloquent that which one of your fields are date attributes like created_at and updated_at, then Eloquent treats them like Carbon objects you define multiple date attributes like this :

Class Role extends \Eloquent {
    
    use \Bigsinoos\JEloquent\PersianDateTrait;
    
    /**
    * Add this method to customize your date attributes
    *
    * @return array
    */
    protected function getDates()
    {
        return ['created_at', 'updated_at', 'expired_at'];
    }
    
}

When using the above trait all of the fields that are treated like date objects by Laravel will be available for conventional converting. They will be also added to model's toJson() , toArray(); and __toString(); methods.

Converter helper method

The $model->convertToPersian($attribute, $format); method allowes you to normally convert one of your fields, from Gregorian date to Jalali date :

$user = Auth::user();
$user->convertToPersian('created_at', 'y/m/d'); // 93/09/08
