Laravel 5 - SimplePaginate函数在这里不起作用？

Question

的功能simplePaginate()直接调用where()功能类似，经过工作：

$posts = $userA->Posts()->simplePaginate(10)->get(); 

的帖子（）函数在用户雄辩：

public function Posts(){ 
    return Post::where('user_id','$this->id')->where('category','programming'); 
} 

对于尚未一切工作正常，但问题是当我有一个以上的用户，所以我做了这个：

//Creating Empty Collection (Working Without any problem) 
$posts = new \Illuminate\Database\Eloquent\Collection; 

//Getting and Adding the userA Posts (Working Without any problem) 
$userA_Posts = $userA->Posts(); 
$posts = $posts->merge($userA_Posts); 

//Getting and Adding the userB Posts (Working Without any problem) 
$userB_Posts = $userB->Posts(); 
$posts = $posts->merge($userB_Posts); 

//Getting and Adding the userC Posts (Working Without any problem) 
$userC_Posts = $userC->Posts(); 
$posts = $posts->merge($userC_Posts); 

//Here Laravel Shows me an ERROR {Method simplePaginate does not exist} 
$posts = $posts->sortByDesc('created_at')->simplePaginate(10)->values()->all(); 

//I changed it to this, ERROR {Method simplePaginate does not exist} 
$posts = $posts->sortByDesc('created_at')->values()->simplePaginate(10)->all(); 

//I changed it to this, ERROR {Method simplePaginate does not exist} 
$posts = $posts->sortByDesc('created_at')->values()->all()->simplePaginate(10); 

在laravel Documentation我没有找到simplePaginate() 功能，但它的工作where()功能后，所以，请 帮助

必须删除->get()，只留下->simplePaginate(10);
