        return $this->hasMany('App\Post');
    }

public function posts(){
        return $this->hasMany('App\Post');
    }

Hey ! @rin4ik same - Error --

        $user = User::find($user_id);
       $user->load('posts')
 return view('dashboard');

         // $user->courses->course_name

         // $user->courses->course_name
    }

Illuminate \ Database \ Eloquent \ RelationNotFoundException Call to undefined relationship [posts] on model [App\User]. same --- :(

ok @towhid all your data should look like this

User model

class User extends Authenticatable
{
    use Notifiable;

    protected $fillable = [
        'name', 'email', 'password',
    ];

    protected $hidden = [
        'password', 'remember_token',
    ];

    public function posts(){
        return $this->hasMany(Post::class);
    }
}

Controller

public function index()
    {
        $user_id = auth()->user()->id;
        $user = User::find($user_id);
       $user->load('posts')
 return view('dashboard')->with('user',$user);


         // $user->courses->course_name
    }

View

<table class="table table-striped">
                        <tr>
                            <th>Title</th>
                            <th></th>
                            <th></th>
                        </tr>
                        <tr>
                            @foreach($user->posts as $post)
                                <td>{{$post->title}}</td>
                                <td><a href="/posts/{{$post->id}}/edit" class="btn btn-default">Edit</a></td>
                                <td></td>
                            @endforeach
                        </tr>
                    </table>

@towhid I suspect you are not getting a User instance as the logic you are using to get the user is incorrect.

This $user_id = auth()->user('id'); will return a User instance, not an id, so this $user = User::find($user_id); will return a Collection, not a User instance. Then, this $user->posts is attempting to get a posts property on a Collection instance.

You can reduce the index method to:

public function index()
{
        $user = auth()->user();
        return view('dashboard')->with('posts', $user->posts);
}

this is incorrect

     $user_id = auth()->user('id');

should be

$user_id = auth()->user()->id;

@rin4ik this is also incorrect:

        $user_id = auth()->user();
        $user = User::find($user_id);

@tykus it was typo I know

when iam trying to do this error show

$user = auth()->user();
        return view('dashboard')->with('posts', $user->posts);

Invalid argument supplied for foreach() (View: C:\xampp\htdocs\project1\resources\views\dashboard.blade.php)

now u have posts not user->posts. change your blade to this

<table class="table table-striped">
                        <tr>
                            <th>Title</th>
                            <th></th>
                            <th></th>
                        </tr>
                        <tr>
                            @foreach($posts as $post)
                                <td>{{$post->title}}</td>
                                <td><a href="/posts/{{$post->id}}/edit" class="btn btn-default">Edit</a></td>
                                <td></td>
                            @endforeach
                        </tr>
                    </table>

If you dd($user->posts); in the controller, what does it give you?

Can you show your relevant Blade template?

if i use this code for post model

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

code for user model

    public function post(){
        return $this->hasMany('App\Post');
    }

this is controller code

public function index()
    {
        $posts = Post::all();
        $user_id = auth()->user()->id;
        $user = User::find('user_id'); //->with('posts',$user->posts)
        return view('dashboard')->with('user',$user)->with('posts',$posts);
}

this is blade code

@foreach($posts as $post)
                            <tr>
                                <td>a{{$post->title}}</td>
                                <td><a href="/posts/{{$post->id}}/edit" class="btn btn-default">Edit</a></td>
                            </tr>
                            @endforeach

an out put is title with Edit action blade view

$user->posts is returning NULL because the relation is still called post - you must update the relation name:

    public function posts(){
        return $this->hasMany('App\Post');
    }

I already told you how to simplify your controller index method; but, you're changing the requirements. Post::all() will return _every` post whether it belongs to the authenticated user or not!

public function index()
{
        $user = auth()->user();
        return view('dashboard')->with('user', $user)->with('posts', $user->posts);
}

i dont know this is right way or wrong ? https://laracasts.com/discuss/channels/laravel/property-posts-does-not-exist-on-this-collection-instance/replies/416545

i think this is not relational Data show - its called again same code use - for direct database :(

please stick with this

public function posts(){
        return $this->hasMany('App\Post');
    }

public function index()
    { 
        $user_id = auth()->user()->id;
        $user = User::find('user_id');  
    $user->load('posts');
        return view('dashboard')->with('user',$user);
}

@foreach($user->posts as $post)
                            <tr>
                                <td>a{{$post->title}}</td>
                                <td><a href="/posts/{{$post->id}}/edit" class="btn btn-default">Edit</a></td>
                            </tr>
                            @endforeach

The issue is that you are trying to pull the relationship from a collection of items and not a single instance.

$user = User::find($user_id); - FIND returns a collection, thus you need ->first()->posts.

Query a single instance and then ask for the relationship. A collection doesn't have relationships, its a list of items.
