_query(query) {
        const {
            pageSize = this.pageSize(),
            page = this.page()
        } = query;

        const url = realizeUri(this.pathname, null, { page, pageSize });
        this.dispatch(requestLocation(url));
    }
}

_query(params) {

            pageSize = this.pageSize(),
            sortBy = this.sorting().sortBy,
            order = this.sorting().order
        } = params;

        const url = realizeUri(this.pathname, null, { page, pageSize, sortBy, order });
        this.dispatch(requestLocation(url));
    }

_query(query) {

            page,
            pageSize
        });
        this.dispatch(requestLocation(url));
    }
}

onToggleSection() {

    }
}

onSort(sorting) {
        const query = ko.deepUnwrap(sorting);
        const url = realizeUri(this.pathname, {}, query);
        action$.next(requestLocation(url));

}

export function redirectTo(route = model.routeContext().pathname, params = {}, query = {}) {
    logAction('redirectTo', { route, params, query });

    const uri = realizeUri(route, Object.assign({}, model.routeContext().params, params), query);
    action$.next(requestLocation(uri, true));
