我正在尝试从我在模型中的函数中放置的查询中访问数据。我试图在控制器中调用该函数,然后将该数据发送到视图。到目前为止,我一直没有成功。这是代码:
型号:Fanartist.php
public function fan_likes() {
$fan_likes = DB::table('fanartists')
->join('artists', 'fanartists.fan_id', '=', 'artists.id')
->where('fanartists.fan_id', '=', Auth::user()->id)
->select('artists.id', 'artists.stage_name', 'artists.city', 'artists.state', 'artists.image_path', 'artists.description');
}
控制器:FansController.php
public function getHome() {
return View::make('fans.home')
->with('fans', Fan::all())
->with('fanartists', Fanartist::fan_likes());
}
查看:
@foreach($fanartists as $fanartist)
{{$fanartist}}
@endforeach
当我运行时,我收到错误:
Non-static method Fanartist::fan_likes() should not be called statically, assuming $this from incompatible context
感谢您的帮助和建议。
更新:
新错误。我正在返回视图,但现在,尝试运行它:
@foreach($fanartists as $fanartist)
{{$fanartist->artists.id}}
@endforeach
我收到错误:
log.ERROR:异常'ErrorException',消息'试图获取非对象的属性'在/ Applications / MAMP / htdocs / crowdsets / laravel-master / app / storage / views / 2ed7fc8952dab08cf4cb4f4e3d40d1ab:100
更新2:
跑步:
@foreach($fanartists as $fanartist)
<?php var_dump($fanartist); ?>
@endforeach
我得到以下输出:
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()
不应该静态调用,但如果要静态调用它,请将fan_likes函数更改为static。
为你的例子
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;
}

如果你的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,您可以使用以下代码调用它:
$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此的视图:
$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() }}}
