NGRX-使用其他模块的效果

Question

你好，我有效果

@Effect({dispatch: false})
createSomething$ = this._actions$.pipe(
    ofType(
        clientsActions.Create),
    mergeMap((action) => this._service.add(action.payload)
        .pipe(
            tap(() => this._router.navigate(['somewhere'])),
            catchError(error => of())
        ))
);

这很好，效果发送请求并重定向，但是现在我想添加，当我尝试做类似的事情

时，其他类的操作

@Effect({dispatch: false})
createSomething$ = this._actions$.pipe(
    ofType(
        clientsActions.Create),
    mergeMap((action) => this._service.add(action.payload)
        .pipe(.map(() => ({type: this.otherActions.doAction),
            tap(() => this._router.navigate(['somewhere'])),
            catchError(error => of())
        ))
);

这不起作用，其他动作也无能为力，甚至没有在开发工具中显示，现在我感到困惑。我也尝试了concatmap等。

使用Mergemap并返回数组[{type：actionType}]

@Effect({dispatch: false})
createSomething$ = this._actions$.ofType(clientsActions.Create)
.pipe(
    mergeMap((action) => this._service.add(action.payload).pipe(
        mergeMap(() => ([{type: this.otherActions.doAction}]),
        tap(() => this._router.navigate(['somewhere'])),
        catchError(error => of())
        ))
);
