            commit(types.GET_TRAVELS_PAGE_NUM)
            commit(types.COM_LOADING_STATUS, true),
            commit(types.GET_TRAVELS_SCORLL_STATUS, false)
            api.TravelsList()
                .then(res => {
                    commit(types.COM_LOADING_STATUS, false),
                    commit(types.GET_TRAVELS_SCORLL_STATUS, true)
                    commit(types.GET_TRAVELS_LIST, res)
                })
        }
    }
}
