我需要显示所有用户的数据，他们在多少天前将其插入数据库？

Question

I am trying to get a Date Count using Carbon. Like 20 days ago created. I want to send data in JSON format API.

I want to send it from the controller. Here is my Controller Code.

use Carbon\Carbon;

public function index()
    
    {
        $now = Carbon::now();
        $users = User::all('first_name', 'last_name', 'profile_img', 'created_at');
        $date = $users->created_at->diffInDays($now);  
        return response()->json(['data' => $users , 'date' => $date]);
    }

But I get the error from the postman

Without the Date count, I can get all data without any error. So My problem is in here just. Please inform me where is I am wrong. Thank You

Answer 1

first of all, you're trying to get data from a collection of objects. it might be pluck or you may use a for each loop here to modify your data. like as -

$date = array();

foreach($users as $user){
 $date[] = $user->created_at->diffInDays($now); // or $user->created_at->diffForHumans();
}

for API you may use resource or Laravel Repository Pattern.

I have done it using model accessor laravel. In User Model I am creating a function

public function getCreatedAtAttribute($created_at)
    {
        return Carbon::parse($created_at)->diffInDays(now());
    }

and In Controller , I have used this code.

public function index()
    {
        $users = User::all('first_name', 'last_name', 'profile_img', 'created_at');
        return response()->json(['data' => $users], 200);
    }

And now IT sends a fine result

Thank's all.

you can also format date in different format like this via model accessor

protected function serializeDate(DateTimeInterface $date)
    {
        return $date->format('Y-m-d H:i:s');
    }
