:mega: Shoutout to [Ankur Kumar](https://github.com/ankurk91) who wrote the original code for this relation in their package [Eloquent Relations](https://github.com/ankurk91/laravel-eloquent-relationships). I created this package as I needed to make a few tweaks to suit my needs. :raised_hands:
## Installation
You can install the package via composer:
```bash
composer require fidum/laravel-eloquent-morph-to-one
```
## Usage
The `MorphToOne` relation is uses Laravel's [MorphToMany](https://laravel.com/docs/7.x/eloquent-relationships#many-to-many-polymorphic-relations) under the hood. However, the difference is that it returns **one** model instead of a `Collection` of models.
If there is no related model in the database it will return `null` where `MorphToMany` would return an empty `Collection`.
Example:
```php
morphToOne(Image::class, 'imageable')
->wherePivot('featured', 1);
//->withDefault();
}
public function images(): MorphToMany
{
return $this->morphToMany(Image::class, 'imageable')
->withPivot('featured');
}
}
```
```php
morphedByMany(Post::class, 'imageable');
}
public function videos(): MorphToMany
{
return $this->morphedByMany(Video::class, 'imageable');
}
}
```
Now you can access the relationship like:
```php
first();
dump($post->featuredImage);
// lazy loading
$post->load('featuredImage');
```
Prefer using `sync` instead of `save` when updating your relation.
```php
$post->featuredImage()->sync([Image::find(123)]);
$post->featuredImage()->sync([Image::find(456)]);
$post->images->count(); // 1 row :)
```
:x: DO NOT use `save` it will follow `morphToMany` behaviour and create rather than update existing.
```php
$post->featuredImage()->save(Image::find(123));
$post->featuredImage()->save(Image::find(456));
$post->images->count(); // 2 rows :(
```
## Testing
``` bash
composer test
```
