Laravel: save image in database - php

Question

I am trying to store an image in my images table that is related to the articles table
When I do this the following error appears:
Indirect modification of overloaded property App\Article::$thumbnail has no effect.
My Article Model:
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Article extends Model
{
protected $fillable = [
'title', 'exerpt', 'body'
];
public function author()
{
return $this->belongsTo(User::class, 'user_id');
}
public function tags()
{
return $this->belongsToMany(Tag::class);
}
public function thumbnail()
{
return $this->hasOne(Image::class);
}
}
My Image Model:
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Image extends Model
{
public function article()
{
return $this->belongsTo(Article::class);
}
}
And the store method in my ArticleController:
public function store(Request $request)
{
$article = new Article($this->validateArticle($request));
//hardcoded for now
$article->user_id = 1;
$thumbnail = '';
$destinationPath = storage_path('app/public/thumbnails');
$file = $request->thumbnail;
$fileName = $file->clientExtension();
$file->move($destinationPath, $fileName);
$article->thumbnail->title = $file;
$article->save();
$article->tags()->attach(request('tags'));
return redirect(route('articles'));
}

Answer 1

Related to your Laravel version, this may works for you:
$article = new Article( $this->validateArticle( $request ) );
$article->user_id = 1;
$article->save();
$article->tags()->attach( request( 'tags' ) );
if( $request->hasFile( 'thumbnail' ) ) {
$destinationPath = storage_path( 'app/public/thumbnails' );
$file = $request->thumbnail;
$fileName = time() . '.'.$file->clientExtension();
$file->move( $destinationPath, $fileName );
$image = new Image;
$image->title = $fileName;
$image->article_id = $article->id;
$image->save();
}

public function store(Request $request){
$product = new product;
if($request->hasfile('image'))
{
$file = $request->file('image');
$exten = $file->getClientOriginalExtension();
$filename = time().".".$exten;
$file->move('uploads/product',$filename);
$product->image = $filename;
}
$product->save();
