laravel 5: relationship between products and featured products - php

Question

I'm writing a sample ecommerce website with Laravel 5.
I have 2 Tables:
Schema::create('products', function (Blueprint $table) {
$table->increments('id');
$table->string('name');
$table->text('description');
$table->float('price');
$table->integer('category_id');
$table->timestamps();
});
and
Schema::create('featureds', function (Blueprint $table) {
$table->integer('product_id')->unique()->unsigned();
});
Schema::table('featureds', function($table) {
$table->foreign('product_id')->references('id')->on('products')->onDelete('cascade');
});
Models
class Product extends Model
{
public function category(){
return $this->belongsTo('App\Category');
}
}
class Featured extends Model
{
public function product(){
return $this->hasOne('App\Product', 'product_id');
}
}
Then, I have a Controller, where I take 4 featured products:
$featured_products = Featured::limit(4)->get();
return view('home', ['featured_products' => $featured_products]);
Now, I'm trying to show these featured products in my view. If i show the product_id from the Featured model, everything is ok:
#foreach($featured_products as $prod)
{{$prod->product_id}}
#endforeach
But I want to take the name of the product referred by the featured. I tried this way:
#foreach($featured_products as $prod)
#foreach($prod as $p)
{{$p->name}}
#endforeach
#endforeach
Because featured_products (in the controller) seems to be a collection, but it doesn't work!

Answer 1

In your Featured model, you have a relationship in method product() when you want to access the relation from the view, you could call the method name as property, in you case, you have a method named product() so you have to call product property like this:
#foreach($featured_products as $prod)
{{ $prod->product->name }}
#endforeach
It will automatically write the product name based on the relationship you have configured in the model.

Edit:
Sorry my bad, I guess you are defining a wrong relation, your Product model, should have a featured() method which uses hasOne relation, while Featured model should have a product() method using belongsTo relation. So in you App\Featured model, you have to define the relation like this:
return $this->belongsTo('App\Product');
And in your App\Product model you should define relation like so:
return $this->hasOne('App\Featured');
Hope it works
