I am trying to access data from a query that I have placed within a function in a model. I am trying to call the function within a controller, and then send along that data to a view. So far, I have been unsuccessful. Here is the code:

Model: Fanartist.php

public function fan_likes() {
        $fan_likes = DB::table('fanartists')
                    ->join('artists', 'fanartists.fan_id', '=', 'artists.id')
                    ->where('fanartists.fan_id', '=', Auth::user()->id)
                    ->select('artists.id', 'artists.stage_name', 'artists.city', 'artists.state', 'artists.image_path', 'artists.description');

           }

Controller: FansController.php

public function getHome() {
            return View::make('fans.home')
            ->with('fans', Fan::all())
            ->with('fanartists', Fanartist::fan_likes());

        }

View: 

@foreach($fanartists as $fanartist)

{{$fanartist}}

@endforeach

When I run this, I get the error:

Non-static method Fanartist::fan_likes() should not be called statically, assuming $this from incompatible context

Thank you for your help and suggestions.

UPDATE:

New error. I am returning the view, but now, trying to run this:

@foreach($fanartists as $fanartist)
                {{$fanartist->artists.id}}

            @endforeach

I get the error:

log.ERROR: exception 'ErrorException' with message 'Trying to get property of non-object' in /Applications/MAMP/htdocs/crowdsets/laravel-master/app/storage/views/2ed7fc8952dab08cf4cb4f4e3d40d1ab:100

UPDATE 2:

running: 

@foreach($fanartists as $fanartist)
<?php var_dump($fanartist); ?>          
            @endforeach

I get the following output:

NULL array(6) { [0]=> string(10) "artists.id" [1]=> string(18) "artists.stage_name" [2]=> string(12) "artists.city" [3]=> string(13) "artists.state" [4]=> string(18) "artists.image_path" [5]=> string(19) "artists.description" } bool(false) string(10) "fanartists" array(1) { [0]=> object(Illuminate\Database\Query\JoinClause)#201 (3) { ["type"]=> string(5) "inner" ["table"]=> string(7) "artists" ["clauses"]=> array(1) { [0]=> array(4) { ["first"]=> string(17) "fanartists.fan_id" ["operator"]=> string(1) "=" ["second"]=> string(10) "artists.id" ["boolean"]=> string(3) "and" } } } } array(1) { [0]=> array(5) { ["type"]=> string(5) "Basic" ["column"]=> string(17) "fanartists.fan_id" ["operator"]=> string(1) "=" ["value"]=> string(1) "1" ["boolean"]=> string(3) "and" } } NULL NULL NULL NULL NULL NULL

Fanartist::fan_likes()不应该被静态调用，但如果你想静态调用它，那么将你的 fan_likes 函数更改为静态。对于你的例子

public static function fan_likes() {
    $fan_likes = DB::table('fanartists')
                ->join('artists', 'fanartists.fan_id', '=', 'artists.id')
                ->where('fanartists.fan_id', '=', Auth::user()->id)
                ->select('artists.id', 'artists.stage_name', 'artists.city', 'artists.state', 'artists.image_path', 'artists.description');
return $fan_likes;
       }

如果您的 MyClass 控制器中有这样的非静态函数：

    public function my_func( ) {
            // do stuff
    return ( $stuff ) ;
}

然后在您的控制器中，您可以使用如下代码调用它：

$local_obj = MyClass::findOrFail( $myobj_id );
$rval = $local_obj->my_func();

如果你想从你的视图中调用它，我认为你需要将对象传递给类似于这样的视图：

$data['my_obj'] = $local_obj;
return View::make('view_name.show')->with('data',$data);

然后在视图中使用这样的东西：

{{{$data['my_obj']->my_func() }}}

（以上是从工作代码中复制和编辑的 - 如果我打错了，请注明）
