Batch uploading and adding files to the database with Laravel - php

Question

I want to add and update multiple images over a form with Laravel v5.6.
I am also trying to associate these added pictures with another model. But while adding, I am encountering an SQL error due to the error I made somewhere. Here is that error:
SQLSTATE[HY000]: General error: 1364 Field 'imageable_id' doesn't have a default value (SQL: insert into `images` (`img_url`, `updated_at`, `created_at`) values (public/images/yxJ0BQDFz2dU5wzKk5uNreHlKl4Z5kmXDRfMug8p.png, 2020-12-19 05:43:29, 2020-12-19 05:43:29))
Thank you in advance for your help!
My Service.php model file:
use Spatie\Sluggable\HasSlug;
use Spatie\Sluggable\SlugOptions;
class Service extends Model
{
/**
* The attributes that are mass assignable.
*
* #var array
*/
protected $fillable = [
'slug',
'title',
'content',
'status',
];
use HasSlug;
/**
* Get the options for generating the slug.
*/
public function getSlugOptions(): SlugOptions
{
return SlugOptions::create()
->generateSlugsFrom('title')
->saveSlugsTo('slug');
}
/**
* Eğer `status` set ediliyorsa...
*
*/
public function setStatusAttribute($value)
{
$this->attributes['status'] = in_array($value, ['on', 'yes', 'ok', 'true']) ? 1 : 0;
}
/**
* Eğer `status` alınıyorsa...
*
*/
public function getStatusAttribute()
{
return $this->attributes['status'] == 1 ? 'on' : null;
}
/**
* Get all of the images for the post.
*/
public function images()
{
return $this->morphMany(Image::class, 'imageable');
}
}
My Image.php model file:
use Illuminate\Database\Eloquent\Model;
class Image extends Model
{
/**
* Fillable fields
*
*/
protected $fillable = [
'name',
'desc',
'img_url',
'imageable_id',
'imageable_type',
];
/**
* imageable items
*
*/
public function imageable()
{
return $this->morphTo();
}
}
And ServiceController.php:
public function store(Request $request)
{
session()->flash('status', $request->status);
$request->validate([
'title' => 'required|between:5,255',
'content' => 'required|min:10',
// 'status' => 'accepted',
'files.*' => 'file|image|mimes:jpeg,png|max:2048',
]);
$service = new Service;
$service->title = $request->title;
$service->content = $request->content;
$service->status = $request->status;
$service->save();
if($request->hasFile('files')) {
collect($request->file('files'))->each(function ($file) use($service) {
// return Storage::putFile('public/images', $file);
// $newFile = Storage::putFile('public/images', $file);
$newFile = $file->store('public/images');
/**
*
* I don't know if the method of adding to the database here is correct.
* I'll be grateful to those who propose the truth:
*
*/
$image = new \App\Image;
$image->img_url = $newFile;
// $image->imageable->create($service);
$image->save();
$service->images()->save($image);
});
}
return redirect(route('admin.services.index'))->with('success', trans('Kayıt başarıyla eklendi'));
}
create.blade.php:
<form action="{{ route('admin.services.store') }}" enctype="multipart/form-data" method="POST">
#csrf
#method('POST')
<!-- ... -->
<div class="form-group">
<label for="files">{{ __('Yükelenecek dosya') }}:</label>
<input type="file" name="files[]" multiple id="files" class="form-control-file" placeholder="{{ __('Yüklenecek dosyaları seçin') }}" aria-describedby="files-label">
<small id="files-label" class="form-text text-muted">
{{ __('Yüklenecek dosyalar .png ve .jpg türlerini içermelidir.') }}
</small>
</div>
<!-- ... -->
</form>

When you call $image->save() that Image does not yet have a foreign key set for imageable_id and your database schema says there must be a value for imageable_id.
Don't call $image->save() as the Model will be saved after you call $service->images()->save($image). That will set the foreign key and save the model for you. So when it saves it will have the needed foreign key field with a value.
