How to force the frontend to fetch data after completing a query to the database on the server?

Question

JavaScript

There is a code like this in angularjs

CPElement.update({id: $scope.elements[elemId].id}, $scope.elements[elemId]).then($scope.calculate());

CPElement is a resource. The data is sent to the server. They are stored on the server. After receiving a response from the server, .then() starts a recalculation request on the server.
The problem is that the recalculation response comes before the actual data in the update request is applied to the database.
I need to send data and receive the result of calculations taking into account them. And now it either succeeds or fails.
Server part on yii2. Controllers are different for saving and for computing.
Tell me where to dig.

Answer 1

As a result, y passed the update function parameter to calback and it worked.

CPElement.update({id: id}, data,function(){

                    $scope.calculate()
                })

Answer 2

1. yii has nothing to do with it
2. Do you understand that then and when are fundamentally different words?

Answer 3

The problem is that the recalculation response comes before the actual data in the update request is applied to the database.

wait until the UPDATE is completed and therefore already send ... mb via @amount or SELECT new data at the query level to SQL, if SQL is used
