Я хочу сохранить динамический компонент в @ ngrx / store. но я получаю ОШИБКУ TypeError: Невозможно заморозить при отправке действия из моего компонента.
Я ссылался на эту страницу Почему я получаю "TypeEror: Cannot freeze"? . и я скопировал компонент объекта. но все равно я получаю эту ошибку.
Компонент:
ngOnInit() {
this.contents$ = this.store.pipe(select(fromContents.getContents));
}
addPhotoChild() {
const componentFactory = this.CFR.resolveComponentFactory(
PhotoChildComponent
);
const componentRef: ComponentRef<PhotoChildComponent> =
this.VCR.createComponent(componentFactory);
const currentComponent = componentRef.instance;
currentComponent.selfRef = currentComponent;
currentComponent.index = this.index++;
currentComponent.userId = this.user.id;
currentComponent.uploadedPhoto.subscribe(val => {
this.photo = val;
const cloneComp = Object.assign({}, currentComponent);
this.store.dispatch(new SaveContents({ comp: cloneComp }));
});
currentComponent.compInteraction = this;
this.componentsReferences.push(componentRef);
}
Действие:
export class SaveContents implements Action {
readonly type = ContentsActionTypes.SAVE_CONTENTS;
constructor(public payload: { comp: PhotoChildComponent | GmapChildComponent }) {}
}
export class LoadContents implements Action {
readonly type = ContentsActionTypes.LOAD_CONTENTS;
}
Разбавление:
export interface ContentsState extends EntityState<PhotoChildComponent | GmapChildComponent> {
allContentsLoaded: boolean;
}
export const adapter: EntityAdapter<PhotoChildComponent | GmapChildComponent> =
createEntityAdapter<PhotoChildComponent | GmapChildComponent>();
export const initialContentsState: ContentsState = adapter.getInitialState({
ids: [],
entities: {},
allContentsLoaded: false
});
export function contentsReducer(state = initialContentsState, action: ContentsActions) {
switch (action.type) {
case ContentsActionTypes.LOAD_CONTENTS: {
return {
...state,
allContentsLoaded: true
};
}
case ContentsActionTypes.SAVE_CONTENTS: {
return adapter.addOne(action.payload.comp, state);
}
default:
return state;
}
}
селектор:
export const selectContentsState = createFeatureSelector<ContentsState>('contents');
export const getContents = createSelector(
selectContentsState,
adapter.getSelectors().selectAll
);
