React-Router-Redux / Sagas / Push Undefined

Question

我在尝试使用 react-router-redux 5.0.0-alpha.9 时遇到了 Saga 中发生的错误。

import { push } from 'react-router-redux';
import ReactOnRails from 'react-on-rails';
import { call, put, takeLatest } from 'redux-saga/effects';
import { LOGIN, loginSuccess, loginFailure } from '../users/actions';
import loginService from './services';

function* loginSaga(action) {
  const { loginValues } = action;

  try {
    const loginData = yield call(loginService, loginValues);
    const store = ReactOnRails.getStore('appStore', false);
    yield put(loginSuccess(loginData));
    yield call(store.dispatch(push('/')));
  } catch (error) {
    yield put(loginFailure(error.response.data.error));
  }
}

function* loginWatcherSaga() {
  yield takeLatest(LOGIN, loginSaga);
}

export default loginWatcherSaga;

问题发生在登录成功时。它将成功调用“loginSuccess”操作，然后转到yield call(store.dispatch(push('/'))); 行，但它会爆炸并跳转到捕获位置。这是错误消息：

login @ LoginForm.jsx:131

基本上就是在轰炸这条线：

yield call(store.dispatch(push('/')));

当我调试它时，push 是未定义的。我没有理由。我有这个确切的代码在不同的传奇中工作：

function* setPasswordSaga(action) {
  try {
    const response = yield call(setPasswordService, action.passwordValues);
    const store = ReactOnRails.getStore('appStore', false);
    yield put(setPasswordSuccess(response));
    yield call(store.dispatch(push('/')));
  } catch (error) {
    yield put(setPasswordFailure(error.response.data.user));
  }
}

它改变了路由就好了。我一直无法弄清楚为什么一个有效而另一个无效。有任何想法吗？

有没有更好的方法来做到这一点？我试图在操作中进行路由，但是在渲染之前组件中的状态没有更新，所以我必须以某种方式执行服务，更新状态，然后更新路由。对执行此操作的最佳方法感到困惑。

谢谢！

试试yield put(push(YOUR_ROUTE))
