Laravel Relationship working, but showing it -> Trying to get property of non object

Question

In my Controller I have:

public function showMainPage()
{
        $categories = Category::with('subcategories.products.prices', 'subcategories.products.image')->get();

        $data = array(
          "categories" => $categories,
        );

        return view('index')->with($data);
}

When I reference this in my view like this:

@foreach($subcategory->products as $product)
    <img src="{{ $product->image->thumbnail }}" alt="">

I get a Trying to get property of non-object error.

This is my relationship:

Product.php

public function image()
    {
        return $this->belongsTo('App\ProductImage');
    }

This is my ProductImage Relationship:

public function product()
    {
        return $this->belongsTo('App\Product');
    }

What is wrong there?

Both relations have a `belongTo`, that's not right. Product should probably be `hasMany`. — Andrei, Sep 13 '16 at 12:52
@Scarwolf it seems like, in your view, you are getting an array instead of a collection. Could you please check using `$product['image']['thumbnail']` — jaysingkar, Sep 13 '16 at 12:56
Andrew: Ooh, you're right. Changed it to hasOne, still the same, though. (1 image row for each product). @jaysingkar That's working. Why do laravel returns an array though? How can I change that back to a collection...? — xTheWolf, Sep 13 '16 at 12:59
sorry @Scarwolf I'm not sure about that. However,you can try passing `$categories` directly without adding it to `$data` array. — jaysingkar, Sep 13 '16 at 13:02
Using `with` may be overriding your relationships. If you have relationships all the way down, try using just `Categories::all()`, then access everything through the relationships. — aynber, Sep 13 '16 at 13:07
@jaysingkar have it like this now: `return view('index')->with('categories', $categories);` doesnt, work. Thank you though! — xTheWolf, Sep 13 '16 at 13:08
@aynber Changed it to `$categories = Category::all();`. Same error: `trying to get property of non-object` — xTheWolf, Sep 13 '16 at 13:09
@aynbar By using a `foreach($categories->subcategories as $subcategory)` which works fine. — xTheWolf, Sep 13 '16 at 13:16
@KetavChotaliya Good catch! As you can see here in line 41: http://pastebin.com/U3FAtcsK image returns an array while prices returns a colletion how it should. But what did I do wrong? — xTheWolf, Sep 13 '16 at 13:19

As per your question, You joined two table with relationship. When you fetch data from categories table it will return categories and product data.

As per given link by you: http://pastebin.com/U3FAtcsK, your $data variable contain this type of hierarchy.

category 
  subcategories
    products
      prices
      image

you are trying to display data of image array.

you have to fetch image data like this.

$categories->subcategories->product->image->thumbnail

Understand your Array Hierarchy. You didn't nothing wrong. :)
