放不更新redux存储

Question

我最近升级到redux-saga v。0.16.0，似乎由saga通过put调度的动作没有立即传递到reducer。因此，我的传奇确实多次请求http。我已经阅读了日志，调试显示出put动作是捆绑在一起并分派的，但是为时已晚。

知道我在做什么错吗？

这里有一些伪代码与生产中的伪代码几乎相同。

const shouldFetchApplications = (state, userId) => {
    return !state.applications[userId].fetched
        &&  !state.applications[userId].fetching; 
}

export function* fetchApplications(action) {
    const userId = action.userId;
    const shouldFetch = yield select(shouldFetchApplications, userId);
    if (shouldFetch) {
        yield put(actions.isFetchingApplications(userId));
        try {
            const data = yield call(get, `/applications?userId=${userId}`);
            yield put(actions.applicationsFetched(data, userId));
        } catch (e) {
            console.log(e);
            yield put(actions.fetchFailed(userId));
        }
    }
}

function* watchFetchApplications() {
    yield takeEvery(actiontypes.FETCH_APPLICATIONS_REQUESTED, fetchApplications);
}

export default function* applicationSagas() {
    yield fork(watchFetchApplications);
}
