laravel - 如何存储在现有的缓存集合中并在 laravel 中更新缓存

Question

return Cache::remember('districts.all',60*60, function (){
    return District::all();
});

缓存集合是

[
 {
    "id": 1,
    "title": "Dhaka"
 },
 {
    "id": 2,
    "title": "Rajshahi"
 },
 {
    "id": 3,
    "title": "Barishal"
 }
]

现在如何在 Districts.all 缓存中添加新内容

 "id":4 ,
 "title":"New District"

以及如何更新此缓存

 "id":3,
 "title":"Khulna"

Answer 1

Laravel 没有直接更新缓存的特殊功能，但您仍然可以districts.all使用新值清除并重新定义它：

Cache::forget('districts.all');

$district = new District();
$district->id = 4;
$district->name = "New District";

Cache::remember('districts.all', 60*60, function () use ($district) {
    return District::all()->push($district);
});
