Any solution for changing inputType fields name?

[arashi-dev]

Hello

I am trying to change all the fields with name _id to id as I am using mongodb but I don't want my users to know that for security issues.
It is easy to change the field names in ObjectTypes but looks like we cannot change names in inputs.

Is there any solution for that? like a middleware?
because half of my project is already done and it will takes a lot of time to change the names manually in the logics I wrote.

I'm not sure if it is a good solution or not, but here is what I did

const Ref = (field: string) => {
    return (target: any, propertyKey: string) => {
        Object.defineProperty(target, propertyKey, {
            set: function (x) { this[field] = x },
            get: function () { return this[field] },
        });
        return target
    }
}

@InputType()
export class UserTestInput {
    @Ref("_id") <============== Ref decoration
    @Field(() => ObjectId, { nullable: true })
    id?: ObjectId

    _id: ObjectId
}

This decoration will replace the field by a getter and a setter with its own name (id in this case) and gets a name as an argument (_id in this example) and change the value of _id whenever we use the id setter.

this might have bugs, I appreciate if you check it and comment what you think about it

You should be able to use getters and setters for aliasing properties, so that it's id outside and _id inside.

@InputType()
export class UserCreateInput {
  balance!: number;

  @Field(_type => Float, {
    nullable: false
  })
  get accountBalance() {
    return this.balance;
  }

  set accountBalance(balance: number) {
    this.balance = balance;
  }
}

Thanks, so I will use the decoration I wrote as it is using this getter/setter approach
