## Introduction

Mango Repo is an Eloquent Repository package that aims at bringing an easy to use and fluent API. Getting started with repository pattern can be 

quite overwhelming. This is especially true for newcomers to Eloquent who are getting the grasp of active record. Behind the scenes Mango Repo 

tries to use as much of the Eloquent API as possible and keeping things simple.

### Installation

Install Mango Repo as you would with any other dependency managed by Composer:



```bash

$ composer require larachimp/mango-repo

```



### Configuration

> If you are using Laravel >= 5.5, you can skip service registration 

> thanks to Laravel auto package discovery feature.



After installing Mango repo all you need is to register the ```LaraChimp\MangoRepo\MangoRepoServiceProvider``` and ```LaraChimp\PineAnnotations\PineAnnotationsServiceProvider``` 

in your `config/app.php` configuration file:



```php

'providers' => [

    // Other service providers...



    LaraChimp\PineAnnotations\PineAnnotationsServiceProvider::class,

    LaraChimp\MangoRepo\MangoRepoServiceProvider::class,

],

```



Optionally you can register the annotations reader alias.



```php

'aliases' => [

    ...

    'AnnotationsReader' => LaraChimp\PineAnnotations\Facades\Reader::class,

],

```



For more information check out the [PineAnnotations package](https://github.com/LaraChimp/pine-annotations) for more information on the annotation reader.



### Creating a repository class

Use the ```mango:make``` command to create your repository classes. This command will take as argument the repository class namesapce (from App) and 

a ```--model``` option which allows you to specify the full namespace of the Eloquent model to which the repository will be tied.



```bash

$ php artisan mango:make "Repositories\Posts" --model="App\Models\Post"

```



The above command will generate the following repository class in the ```app/Repositories``` directory:



```php

posts = $posts;

    }

    

    public function index()

    {

        $allPosts = $this->posts->all();

        //

    }

}

```



> Take note that the repository class can be injected in not only controllers' constructors, but also methods and any service which is resolved by the service container.



You can also use the ```app()```, ```app()->make()``` or ```resolve()``` method to resolve an instance of your repository class and use it as you please:



```php

make(Posts::class)->all();

        //

    }

}

```



Although resolving repository classes from the service container seems the most efficient way to building up an instance, you may prefer to instantiate

your repository classes manually for some reasons. To achieve this call the ```boot()``` method on the new instance before using it.



The ```boot()``` method will take care of loading the repository class dependencies for us:



```php

$posts = (new \App\Repositories\Posts())->boot();

```



### Available Methods

Out of the box, repository classes comes with these methods already written for you. However, you are free to add your own methods or override 

existing methods in your repository class for building your own custom API and business logic.



To keep things as simple as possible, for many of theses methods, Mango Repo makes use of the same methods available on the Eloquent model.

Hence, Mango Repo's API tries to be as close to Eloquent's API as possible.



#### ```all()```

Get all of the models from the database: 



```php

$users = app(\App\Repositories\Users::class)->all();



// Illuminate\Database\Eloquent\Collection

```

or:

```php

$users = app(\App\Repositories\Users::class)->all(['name', 'email']);



// Illuminate\Database\Eloquent\Collection instance

```



#### ```paginate()```

Paginate the models from the database:



```php

$users = app(\App\Repositories\Users::class)->paginate(10, ['name', 'email']);



// Illuminate\Contracts\Pagination\LengthAwarePaginator instance

```



#### ```simplePaginate()```

Paginate the models from the database into a simple paginator:



```php

$users = app(\App\Repositories\Users::class)->simplePaginate(10, ['name', 'email']);



// Illuminate\Contracts\Pagination\Paginator

```



#### ```create()```

Save a new model and return the instance:



```php

$user = app(\App\Repositories\Users::class)->create([

            'name'     => 'John Doe', 

            'email'    => '[email protected]'

            'password' => Hash::make('secret')

         ]);

 

 // Illuminate\Database\Eloquent\Model

```



#### ```update()```

Update a model in the database. The update method accepts as its second argument

either the model instance or the model id:



```php

app(\App\Repositories\Users::class)->update(['name' => 'John Smith'], $userId);



// bool

```

or:

```php

app(App\Repositories\Users::class)->update(['name' => 'John Smith'], $user);



// bool

```



#### ```delete()```

Delete a record from the database.The delete method accepts as its first argument 

either the model instance or the model id:



```php

app(\App\Repositories\Users::class)->delete($userId);



// bool

```

or:

```php

app(\App\Repositories\Users::class)->delete($user);



// bool

```



#### ```find()```

Find a Model in the Database using the ID:



```php

app(\App\Repositories\Users::class)->find($userId);



// Illuminate\Database\Eloquent\Model

```

or:

```php

app(\App\Repositories\Users::class)->find($user_id, ['name', 'email']);



// Illuminate\Database\Eloquent\Model

```



#### ```findOrFail()```

Find a model in the database or throw an exception:



```php

app(\App\Repositories\Users::class)->findOrFail($userId);



// Illuminate\Database\Eloquent\Model

```

or:

```php

app(\App\Repositories\Users::class)->findOrFail($userId, ['name', 'email']);



// Illuminate\Database\Eloquent\Model

```



#### ```findBy()```

Find a model or models using some criteria:



```php

app(\App\Repositories\Users::class)->findBy(['last_name' => 'Doe']);



// Illuminate\Database\Eloquent\Collection

```

or:

```php

app(\App\Repositories\Users::class)->findBy(['last_name' => 'Doe'], ['last_name', 'email']);



// Illuminate\Database\Eloquent\Collection

```



#### ```getModel()```

Gets the Eloquent model instance:



```php

app(\App\Repositories\Users::class)->getModel();



// Illuminate\Database\Eloquent\Model

```



### Model Repository Scoping

Mango Repo do not make use of long and tedious "Criterias classes" for filtering queries, instead any repository class 

created using the ```mango:make``` command can be "Model Scoped". In simpler terms this only means that you may access 

[Local Query Scopes](https://laravel.com/docs/master/eloquent#local-scopes) defined on your models directly on the repository class.



Hence, you define your query scopes once on your model classes and use them directly on your repository classes for query filtering.



Consider the following example:



```php

where('is_active', true);

    }

}

```



Since we've defined a local scope ```Active``` on our User Model, we don't have to rewrite the same scope twice within our

repository class. We simple use it directly on the repository class. Yes as simple as that!



```php

$activeUsers = app(\App\Repositories\Users::class)->active()->get();



// Illuminate\Database\Eloquent\Collection

```



You may even chain scopes and apply other filters as you would for any Eloquent model instance:



```php

 $users = app(\App\Repositories\Users::class)->popular()->active()->orderBy('created_at')->get();

 

 // Illuminate\Database\Eloquent\Collection

```



### Going Further

We think we've done a good job here at creating a simple but yet rich boilerplate for creating repository classes and in most cases

you would probably just create repository classes using the ```mango:make``` command like a breeze. However, if you still are not satisfied

and require creating your custom repository classes that do not need to be Model Scoped and so on; fear not we've got you covered.



First start by creating a class that implements ```LaraChimp\MangoRepo\Contracts\RepositoryInterface```. Now you may implement all the

methods available as you wish.



```php
