Mutate Driver #

This query allows users to decide what field of a DRIVER object they want to change. However, you can change only one field at a time.

Query Structure: #

updateDriver(
    driverid: ID!
    key: String!
    value: String!
): Driver

Argument(s): #

This query must be made with the following arguments:

1. Driver Id

   driverid : ID - the unique identifier of a driver (compulsory)

2. Key

   id : String - the field name of a driver object (compulsory)

3. Value

   id : String | Float | Int - the new value of a field (compulsory). It can either be a string, integer or float (compulsory)

The key of a mutation query must be in accordance with the Type Definitions and Schema of a DRIVER as described in the section above.

Response: #

A driver with new (updated) details. The response type is an Object

Example: #

• Changing the last name of a driver

FORMER DATA:
{
  "data": {
    "driver": {
      "firstName": "Max",
      "lastName": "Munstermann",
      "id": "8908019a-0eeb-eefa-d0ca-f4c94074c70a"
    }
  }
}

In this example, the last name of a driver will be changed from "Munstermann" to "Falke". Therefore, the "key" of the mutation will be "lastName" and the "value" will be "Falke".

WRITING THE MUTATION:

mutation {
  updateDriver(
    driverid: "8908019a-0eeb-eefa-d0ca-f4c94074c70a"
    key: "lastName"
    value: "Falke"
  ) {
    firstName
    lastName
    id
  }
}

RESPONSE (with new data)
{
  "data": {
    "updateDriver": {
      "firstName": "Max",
      "lastName": "Falke",
      "id": "8908019a-0eeb-eefa-d0ca-f4c94074c70a"
    }
  }
}
