Laravel未知专栏

I have a problem with this error:

https://pastebin.com/cgm5yq0P

This is my form:

https://pastebin.com/bSU5X5EC

This is my web.php (route controller):

Route::post('/komentarz', 'VideosController@postComment');

This is my VideoController postComment function:

https://pastebin.com/SYbEjB8H

This is my Comment model:

https://pastebin.com/SxHX6gTP

This is my User model comments function:

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

This is my Video model comments function:

public function comments(){ return $this->belongsToMany('App\Comment')->withTimestamps(); }

And finally, Migration file named create_comments_table:

https://pastebin.com/2cHscQfq

My Routes: https://pastebin.com/ki8FZ0C6 Please help me with this.. I dunno what is wrong

Your foreign keys are wrong. Change your migration to this.

$table->unsignedInteger('user_id');
$table->foreign('user_id')->references('id')->on('users')->onDelete('cascade');

$table->unsignedInteger('video_id');
$table->foreign('video_id')->references('id')->on('videos')->onDelete('cascade');

Edit : This adds the comment and attaches it to the video and user.

// model fillable property

protected $fillable = [
    'text', 'user_id', 'video_id',
];

// route
Route::post('/film/{id}/komentarz', 'VideosController@postComment');

// controller method
public function postComment(CreateCommentRequest $request, $id)
{
    $video = Video::findOrFail($id);

    $video->comments()->create([
        'text' => $request->text,
        'user_id' => auth()->id(),
    ]);

    return 'works';
}

// form
{!! Form::open(['url' => "/film/{$video->id}/komentarz", 'method' => 'post','class' => 'form-horizontal']) !!}
<div class="form-group">
    <div class="col-md-3 control-label">
        {!! Form::label('text', 'Treść komentarza:') !!}
    </div>
    <div class="col-md-8">
        {!! Form::textarea('text', null, ['class'=>'form-control', 'size' => '5x5']) !!}
    </div>
</div>
<div class="form-group">
    <div class="col-md-8 col-md-offset-3">
        {!! Form::submit('Dodaj', ['class'=>'btn btn-primary btn-comment']) !!}
    </div>
</div>
{!! Form::close() !!}

in comment model i see 'user' in fillable, not 'user_id'. i think it should be user_id. or you could use

protected guarded = [];

instead of using fillable array.
