Laravel更改分页数据 [英] Laravel change pagination data

问题描述

我的Laravel分页输出就像以前的laravel分页一样，但是我需要更改每个对象的数据数组.我的输出是:

如您所见，数据对象有2个项目，我需要更改.

我的代码是:

  $ items = $ this-> items()-> where('position'，'='，null)-> paginate(15)； 

哪个返回带有枢轴表的用户项，但是我不喜欢在JSON中显示枢轴表的方式，所以我决定更改项并在项之前使用枢轴来组织每个项.>

为此，我尝试使用 foreach

  foreach($ items->数据作为$ item){} 

由于我不知道的原因，这给了我一个错误:

 未定义的属性:Illuminate \ Pagination \ LengthAwarePaginator :: $ data状态码:500 

有帮助吗?

解决方案

分页者的项目是一个集合.您可以抓取它并转换数据，如下所示:

  $ paginator = $ this-> items()-> where('position'，'='，null)-> paginate(15);$ paginator-> getCollection()-> transform(function($ value){//您的代码在这里返回$ value;}); 

如果您熟悉 tap 助手，则此代码段的功能完全相同.

  $ paginator = tap($ this-> items()-> where('position'，'='，null)-> paginate(15)，function($ paginatedInstance){返回$ paginatedInstance-> getCollection()-> transform(function($ value){返回$ value;});}); 

我们无法链接方法getCollection 到paginator实例，因为 AbstractPaginator 将返回paginator的基础集合.因此分页程序实例将转换为Collection.因此，请修复此问题，以便我们可以使用点击助手.

My Laravel pagination output is like laravel pagination used to be, but I need to change the data array for each object. My output is:

As you can see, the data object has 2 items, which I need to change.

My code is:

$items = $this->items()
        ->where('position', '=', null)
        ->paginate(15);

Which returns the user items with pivot table, but I don't like the way the pivot table is shown in the JSON, so I decided to change the items and organize each item with the pivot before the item.

For this purpose, I tried to use foreach

foreach ($items->data as $item)
        {

        }

which giving my an error, for a reason I don't know:

Undefined property: Illuminate\Pagination\LengthAwarePaginator::$data"
status_code: 500

Any help?

解决方案

The paginator's items is a collection. You can grab it and transform the data like so:

$paginator = $this->items()->where('position', '=', null)->paginate(15);
$paginator->getCollection()->transform(function ($value) {
    // Your code here
    return $value;
});

If you are familiar with tap helper here is the snippet that does exact same.

$paginator = tap($this->items()->where('position', '=', null)->paginate(15),function($paginatedInstance){
    return $paginatedInstance->getCollection()->transform(function ($value) {
        return $value;
    });
});

We can't chain method getCollection to paginator instance because AbstractPaginator will return paginator's underlying collection. so the paginator instance will be transformed to Collection. So fix that we can use tap helper.
