Laravel Eloquent中不存在orderBy方法吗? [英] Method orderBy does not exist in Laravel Eloquent?

问题描述

我有一段这样的代码:

$products = Product::all()

if ($search_value) {
    $products = $products->where('name', 'LIKE', "%$search_value%");
}

$products = $products->orderBy('created_at', 'desc')->skip(10)->take(10)->with('tags')->get();

我遇到以下错误:

BadMethodCallException in Macroable.php line 81:
Method orderBy does not exist.

我猜orderBy需要直接跟随Product::，但是我无法保存$products = Product::，可以吗?

I guess orderBy need to follow Product:: directly, but I can't save $products = Product::, can I?

有什么建议吗?谢谢.

推荐答案

您正试图在Eloquent集合上使用orderBy()方法.尝试改用 sortByDesc() .

You're trying to use orderBy() method on Eloquent collection. Try to use sortByDesc() instead.

或者，您可以将$products = Product::all();更改为$products = new Product();.然后，所有代码都将按预期工作.

Alternatively, you could change $products = Product::all(); to $products = new Product();. Then all your code will work as you expect.
