AJAX将数据发送到控制器，如何更新正确的ID？

Question

I am using ajax to post data to the controller and I need to update the record based on the id I pass through. How would I go about this with Laravel Eloquent? Here is the controller...I know the data is being passed to the controller correctly just don't know how to update based on the id I send. Thank you for your help.

public function home(Request $request) {

$updateCus = New Customer($request->all());
$updateCus->update()->where('id', $request['id']);

}

Answer 1

Correct syntax is:

Customer::where('id', $request->id)->update([
    'name' => $request->name,
    'country' => $request->country,
]);

Or, if you want to update many columns:

Customer::where('id', $request->id)->update($request->all());
