Property [subcategory] does not exist on this collection instance

Question

First time working with eloquent relationship. I'm trying to access the subcategory method yet I get this error:

Property [subcategory] does not exist on this collection instance.

New to laravel so any help would be appreciated!

blade

                <table class="table">
                    <thead>
                        <tr>
                            <th scope="col">Category</th>
                            <th scope="col">Sub-category</th>
                        </tr>
                    </thead>
                    <tbody>
                        @foreach ($categories as $cat)
                            <tr>
                                <td scope="row">{{$cat->name}}</td> 

                                 //error here
                                @foreach ($categories->subcategory as $item)
                                    <td>{{$item->name}}</td>
                                @endforeach

                            </tr>
                            @endforeach
                    </tbody>
                </table>

category model

class Category extends Model
{
protected $fillable = ([
    'name'
]);

public function subcategory(Type $var = null)
{
    # code...
    return $this->hasMany(Subcategory::class,'category_id','id');
}
}

subcategory model

class Subcategory extends Model { protected $fillable = ([ 'category_id', 'name' ]);

public function category(Type $var = null)
{
    # code...
    return $this->belongsTo(Category::class);
}
}

controller

public function create()
{
    $categories = Category::all();
    // dd($categories);
    return view('settings.create', compact('categories'));
}

You are doing wrong in foreach loop. Your second foreach loop will be like

@foreach ($categories as $cat)
    <tr>
        <td scope="row">{{$cat->name}}</td> 
        @foreach ($cat->subcategory as $item)
        <td>{{$item->name}}</td>
        @endforeach

    </tr>
@endforeach

your current object is $cat and $categories is a collection.

Oh thank you! I thought I would still have to work with the `$categories` thank you! – kwestionable Sep 04 '19 at 05:49
relation always belong to an object. not on collection. – zahid hasan emon Sep 04 '19 at 05:51

You are calling subcategory of $categories collection not on one model $cat. So change your @foreach method to

@foreach ($cat->subcategory as $item)
   <td>{{$item->name}}</td>
@endforeach

My solution:

 @foreach ($cat->subcategory as $item)        
    <td>{{$item->name}}</td>    
 @endforeach
