我正在使用Angular 2开发一个应用程序，我有两个实体：DemandeMedicamentVff和Medicament。
我在Accepter中也有一个名为DemandeMedicamentVff的按钮，当我点击etat属性时，我希望它更改为“accptée”，但我也想< / p>
'Medicament.nom== DemandeMedicament.medicamentid && demandeMedicament.etat= 'Acceptée' {Medicament.quantity = Medicament.quantity-DemandeMedicament.quantity'}'
执行此操作后，值etat已更改，但quantity未更改。
这些是我的模特：
第一个模型
export class DemandeMedicamentVff {
constructor(
public id?: string,
public medicamentid?: string,
public date?: any,
public quantity?: number,
public etat?: number,
public signature?: string,
) { }
}
第二个模型：Medicament
export class Medicament {
constructor(
public id?: string,
public nom?: string,
public type?: string,
public quantity?: number,
public ref?: string,
public datevalidite?: any,
public dateproduction?: any,
) { }
}
我的组件

this.medicaments.forEach((Medicament,index)=>

if (Medicament.nom== Demandemedicamentvff.medicamentid && Demandemedicamentvff.etat=="Acceptée")

);
Demandemedicamentvff.etat="Acceptée";
this.demandemedicamentvffService.update(Demandemedicamentvff).subscribe((res: Demandemedicamentvff) =>
this.onSaveSuccess(res),
(res: Response) => this.onError(res.json()));
}
private onSaveSuccess (result: Demandemedicamentvff) {
this.eventManager.broadcast({ name: 'demandeModification', content: 'OK'});
this.isSaving = false;
}
Refuser(Demandemedicamentvff){
Demandemedicamentvff.etat="Refusée";
this.demandemedicamentvffService.update(Demandemedicamentvff).subscribe((res: Demandemedicamentvff) => this.onSaveSuccess(res),

}
ngOnInit() {
this.loadAll();
this.principal.identity().then((account) => {
this.currentAccount = account;
});
this.registerChangeInDemandemedicamentvffs();
}
ngOnDestroy() {
this.eventManager.destroy(this.eventSubscriber);
}
trackId (index: number, item: Demandemedicamentvff) {
return item.id;
}
registerChangeInDemandemedicamentvffs() {
this.eventSubscriber = this.eventManager.subscribe('demandemedicamentvffListModification',
(response) => this.loadAll());
}
sort () {
let result = [this.predicate + ',' + (this.reverse ? 'asc' : 'desc')];
if (this.predicate !== 'id') {
result.push('id');
}
return result;
}
private onSuccess (data, headers) {
this.links = this.parseLinks.parse(headers.get('link'));
this.totalItems = headers.get('X-Total-Count');
this.queryCount = this.totalItems;
// this.page = pagingParams.page;
this.demandemedicamentvffs = data;
}
private onError (error) {
this.alertService.error(error.message, null, null);
}
}
这是medicament.service.ts中的功能更新：
update(medicament: Medicament): Observable<Medicament> {
let copy: Medicament = Object.assign({}, medicament);
copy.datevalidite = this.dateUtils
.convertLocalDateToServer(medicament.datevalidite);
copy.dateproduction = this.dateUtils
.convertLocalDateToServer(medicament.dateproduction);
return this.http.put(this.resourceUrl, copy).map((res: Response) => {
return res.json();
});
}
如果我在不具有dateproduction和datavalidite的药物上执行功能Accepter，但是如果我在另一种具有datevalidite和dateproduction的药物上做了这个功能我得到了这个错误：

答案 0 :(得分：0)
Medicament.quantity = Medicament.quantity -
Demandemedicamentvff.quatite;
属性名称不好，应为quantity。
