AngularJS resource with getter in params

Question

I'm trying to access an API with angularResource.get(params)

The model for the class looks like this:

export class d_stp_searchbar implements Id_stp_searchbar {

    lperiode?: number;
    private _lsichtweise: number;
    scode?: string;
    sbezeichnung?: string;
    bezeichnungLabel: string;

    set lsichtweise(value) {
        this._lsichtweise = value;
        this.bezeichnungLabel = this.lsichtweise === 5 ? "Name" : "Bezeichnung";
    }

    get lsichtweise() {
        return this._lsichtweise;
    }

    public bezeichnung() {
        if (this.lsichtweise === 5) {
            this.bezeichnungLabel = "Name";
        } else {
            this.bezeichnungLabel = "Bezeichnung";
        }
    }
}

The function, where i call the api looks like the following:

searchStundenplan(params: d_stp_searchbar): angular.IPromise<any> {
    this.searchStundenplanParams = params;
    this.localStorageService.set("searchStundenplanParams", this.searchStundenplanParams);

    return this.searchStundenplanResource.get(params)
        .$promise.then((result) => {
            this.searchStundenplanResult = result;
            this.searchStundenplanResultChangedNotify();
        });
 }

The problem I'am facing is, that the URL that will be called looks like this:

GET /api/search/Stundenplan?_lsichtweise=1&bezeichnungLabel=Bezeichnung&lperiode=86

but I want, that instead of _lsichtweise lsichtweise will be used.

Do I use it wrong or does somebody know, why not the public property lsichtweise is used?

Thanks in advance

There is no public property lsichtweise in your class d_stp_searchbar. You created a magic function get but angular.IPromise does only recognize class vars and ignores the magic getter function. Just add a public class property lsichtweise: number;. Maybe angular.IPromise will call the magic getter function and you will be fine. — lin

An other attemp is to remap your model attributes while they are parsed as params into angular.IPromise. Which solution you would prefer? — lin

The problem was, that the d_stp_searchbar was only instantiated properly the first time we called it. So your comment was not the solution, but a gamechanger for further investigations. Thank you! — florianbaer

I was able to fix it by myself:

The problem was, that the d_stp_searchbar was only instantiated properly the first time we called it.

We were loading a JSON into a TypeScript object like this:

this.searchParamsStundenplan = localStorageService.get("searchParamsStundenplan") as d_stp_searchbar;

but then the searchParamsStundenplan does not contain the (in the question mentioned) lsichtweise getter and setter because it was a plain data object without any functions.

So we had to create an instance the following way:

let searchParamsStundenplanTemp = new d_stp_searchbar();
searchParamsStundenplanTemp.bindinglsichtweise = this.searchParamsStundenplan.bindinglsichtweise;
searchParamsStundenplanTemp.lperiode = this.searchParamsStundenplan.lperiode;
searchParamsStundenplanTemp.scode = this.searchParamsStundenplan.scode;
this.searchParamsStundenplan = searchParamsStundenplanTemp;

This way it worked.
