选择前 10 行 - Laravel Eloquent

2021-12-26 00:00:00 orm php laravel eloquent

到目前为止，我有以下模型:

So far I have the following model:

class Listing extends Eloquent {
     //Class Logic HERE
}

我想要一个基本函数来检索表列表"的前 10 行并将它们传递给视图(通过控制器?).

I want a basic function that retrieves the first 10 rows of my table "listings" and passes them on to the view (via a controller?).

我知道这是一项非常基本的任务，但我找不到一个简单的指南来实际解释如何显示一组基本结果，同时详细说明模型、控制器和视图文件中的要求.

I know this a very basic task but I can't find a simple guide that actually explains step-by-step how to display a basic set of results, whilst detailing what is required in the model, controller and view files.

推荐答案

首先你可以使用分页器.这很简单:

First you can use a Paginator. This is as simple as:

$allUsers = User::paginate(15);

$someUsers = User::where('votes', '>', 100)->paginate(15);

变量将包含一个分页器类的实例.您的所有数据都将存储在 data 键下.

The variables will contain an instance of Paginator class. all of your data will be stored under data key.

或者您可以执行以下操作:

Or you can do something like:

旧版本的 Laravel.

Old versions Laravel.

Model::all()->take(10)->get();

较新版本的 Laravel.

Newer version Laravel.

Model::all()->take(10);
