Counter Cache for Laravel - Updated 11/10/2016
==============================================

[](#counter-cache-for-laravel---updated-11102016)

Counter Cache for Laravel

Why ?
-----

[](#why-)

Imagine if you have to show 50 products in a list and have to show a counter for how many comments that product have, too much queries, right ? This package will allow you to super reduce the number of queries made.

Feature Overview
----------------

[](#feature-overview)

- Increment counter automatically when creating a new record.
- Decrement counter automatically when deleting a record.
- Update counter automatically when updating a record
- ...

Installation
------------

[](#installation)

Add this to your composer.json file, in the require object:

```
"kanazaca/counter-cache": "1.0.*"
```

After that, run composer install to install the package. Add the service provider to `config/app.php`, within the `providers` array.

```
'providers' => array(
	// ...
	kanazaca\CounterCache\CounterCacheServiceProvider::class,
)
```

Basic Usage
-----------

[](#basic-usage)

I will use the example products/comments, one product have many comments

### Migration

[](#migration)

You need to create a field in the table that you want access the counter, like the example below:

```
Schema::create('products', function (Blueprint $table) {
      $table->increments('id');
      $table->string('name');
      $table->string('ref');
      $table->integer('comments_count')->default(0); // This is the counter that you have to add
      $table->timestamps();
  });
```

After this run `php artisan migrate`

### Model

[](#model)

Comments model, you have to use the trait, define the $counterCacheOptions and make the relation with the product :

```
namespace App;

use Illuminate\Database\Eloquent\Model;
use kanazaca\CounterCache\CounterCache;

class Comments extends Model
{
    use CounterCache;

    // you can have more than one counter
    public $counterCacheOptions = [
        'Product' => ['field' => 'comments_count', 'foreignKey' => 'product_id']
    ];

    public function Product()
    {
        return $this->belongsTo('App\Product');
    }
}
```

Filters
-------

[](#filters)

If you want to do some filtering before the counter cache magic happens, you have to add the key `filter` to `$counterCacheOptions` with the name of your method that will provide the filter, as string, like below:

```
public $counterCacheOptions = [
    'Product' => [
        'field' => 'comments_count',
        'foreignKey' => 'product_id',
        'filter' => 'CommentValidatedFilter'
    ]
]; // you can have more than one counter

// this code will be executed before the counting (save and update method)
public function CommentValidatedFilter()
{
    if ($this->validated) {
        return true;
    }

    return false;
}
```
