Missing argument 1 for Illuminate\Support\Collection::get()
提问by wobsoriano
I have a simple Laravel 5.1 code and I'm getting the ErrorExceptionMissing argument 1 for Illuminate\Support\Collection::get(). Here is the code:
我有一个简单的 Laravel 5.1 代码，我得到了ErrorExceptionMissing argument 1 for Illuminate\Support\Collection::get(). 这是代码：
public function boot()
{
$news = News::all()->take(5)->get();
view()->share('sideNews', $news);
}
Whenever I remove the ->get();there, it works. It's my first time using eloquent. I remember when I'm using the query builder, I always add the ->get()in the last line of the code. Am i doing it correctly? Thank you.
每当我删除->get();那里时，它就会起作用。这是我第一次使用eloquent. 我记得当我使用查询构建器时，我总是->get()在代码的最后一行添加。我做得对吗？谢谢你。

不要使用以下all方法：
public function boot()
{
$news = News::take(5)->get();
view()->share('sideNews', $news);
}

I have faced this issue while paginate()function.
我在paginate()函数时遇到了这个问题。
Simple Solution
简单的解决方案
Remove get()after paginate()or take()
get()在paginate()或之后删除take()
What cause this error?
什么原因导致这个错误？
If we use get()function after paginate()or take()like paginate(5)->get()then this error will occur.
如果我们使用get()afterpaginate()或take()like函数，paginate(5)->get()则会发生此错误。
