php - Laravel 集合循环到另一个集合

Question

如何将 Eloquent 集合从一个循环到另一个？我只是得到数组的第一行。我在集合中有超过 4 个数组。

$queries = Students::where('year',"=", 1)->get();
$students = new Students();
foreach ($queries as $query) {
    $students->name = $query->name;
    $students->faculty = $query->faculty ."Add something";
    $students->year = $query->year;
}
dd($students);

Answer 1

I want to change the collection a bit before I print to json. For example, I want add something behind the faculty

使用 transform()修改集合的方法:

$students = Students::where('year', 1)->get();
$students->transform(function($i) {
    $i->faculty = $i->faculty . 'add something';
    return $i;
});

您也可以使用 resource classes在返回 JSON 响应之前转换数据。
