I related 2 models - Category and News, each new can have 1 category assign to itself. The problem is that I can't access the category that I assigned to the new, my question is how to make it work ? And why my way doesn't work.
Categroy model-
public function news(){
return $this->hasMany('App\News');
}
News model -
public function category(){
return $this->belongsTo('App\Categroy');
}
CategoryController - $categories = DB::table('categroys')->get(); dd($categories->news);
$categories = DB::table('categroys')->get(); dd($categories->news);
message -
"Property [news] does not exist on this collection instance."
This line will return instance of Collection. It is not a model itself. It is all items in categories table. $categories = DB::table('categroys')->get();
foreach($categories as $category) { $news = $category->news(); }
But in this case you will get a first item and it is a model
$categories = DB::table('categroys')->first();
So you should use either foreach or take only the first item of collection.
This is Eloquent Relationships . This relationship only works with Model.
$categories = Categroy::all();
foreach($categories as $category) {
// $category->news
}
You can eager loading your news
method as follow:
$categories = Category::with(['news'])->get();
dd($caregories);
