    Trying to get property of non-object

while i am using same approach for other table and copied same method here but getting error.

See my Blade file code, i am calling object inside foreach loop

      @foreach ($subjects as $subject)
                    <tr>
                      <td width="8%">{{$subject->id}}</td>
                      <td width="22%">{{$subject->subject}} </td>
                      <td width="22%">{{$subject->cat->name}}</td>
                        <!-- <a class="btn btn-success btn-sm" href="{{route('subjects.show', $subject->id)}}"><i class="fa fa-eye"></i></a> |  -->
                        <a href="{{route('subjects.edit', $subject->id)}}" class="btn btn-warning btn-sm"><i class="fa fa-pencil"></i></a> |
                          {!! Form::open(['route' => ['subjects.destroy', $subject->id], 'method' => 'DELETE', 'class' => 'delete-form']) !!}
                          {{ Form::button('<i class="fa fa-times" aria-hidden="true"></i>', ['class' => 'btn btn-danger btn-sm pull-left', 'type' => 'submit']) }}
                          {!! Form::close() !!}
                      </td>
                    </tr>
                    @endforeach

Try this

$cat = json_decode($subject->cat); // returns object {{ $cat['name'] }}

or

$cat = json_decode($subject->cat, true); // returns array {{ $cat['name'] }}

You need to decode your json and then use like this:

$result = json_decode ($subject->cat);
echo $result->name;

Use your variable name in place of $result

Just use json_decode like:

$var = json_decode($subject, true);

Then you can use: 

{{$subject->cat->name}}

See more here!

Hope this helps you!

First Use json_decode($json);

Takes a JSON encoded string and converts it into a PHP variable.

Then 

Use {{$subject->cat}}
