Installation

You can install the package via composer:

composer require mayoz/laravel-categorizable

Register the service provider in your config/app.php configuration file:

'providers' => [
    ...
    Mayoz\Categorizable\CategorizableServiceProvider::class,
    ...
];

You can publish the migration with:

php artisan vendor:publish --provider="Mayoz\Categorizable\CategorizableServiceProvider" --tag="migrations"

The migration has been published you can create the categories and categorizable tables. You are feel free for added new fields that you need. After, run the migrations:

php artisan migrate

Usage

Suppose, you have the Post model as follows:

<?php

namespace App;

use Mayoz\Categorizable\Categorizable;
use Illuminate\Database\Eloquent\Model;

class Post extends Model
{
    use Categorizable;
}

Associate new categories for the Post model:

$post = Post::find(1);

$post->categorize([1, 2, 3, 4, 5]);

return $post;

Now, the post model is associated with categories ids of 1, 2, 3, 4 and 5.

Remove the existing category association for the Post model:

$post = Post::find(1);

$post->uncategorize([3, 5]);

return $post;

The post model is associated with categories ids of 1, 2 and 4.

Rearrange the category relationships for the Post model:

$post = Post::find(1);

$post->recategorize([1, 5]);

return $post;

The post model is associated with categories ids of 1 and 5.

Extending

I suggest, you always extend the Category model to define your relationships directly. Create you own Category model:

<?php

namespace App;

use Mayoz\Categorizable\Category as BaseCategory;

class Category extends BaseCategory
{
    /**
     * Get all posts for the relation.
     *
     * @return \Illuminate\Database\Eloquent\Relations\MorphedByMany
     */
    public function posts()
    {
        return $this->categorized(Post::class);
    }
}

You publish the package config:

php artisan vendor:publish --provider="Mayoz\Categorizable\CategorizableServiceProvider" --tag="config"

This is the contents of the published config file:

<?php

return [

    /*
    |--------------------------------------------------------------------------
    | Model Namespace
    |--------------------------------------------------------------------------
    |
    | Change these values when you need to extend the default category model
    | or if the user model needs to be served in a different namespace.
    |
    */

    'category' => App\Category::class,

];

That is all. Now let's play for relationship query with the category.

/**
 * Respond the post
 *
 * @param  \App\Category  $category
 * @return \Illuminate\Http\Response
 */
public function index(Category $category)
{
    return $category->posts()->paginate(10);
}

If we did not extend the Category model, as had to use;

/**
 * Respond the post
 *
 * @param  \App\Category  $category
 * @return \Illuminate\Http\Response
 */
public function index(Category $category)
{
    return $category->categorize(Post::class)->paginate(10);
}
