如何清理您的商店

Question

在发布之前，我试图阅读this post

中的Dan Abramov的超级答案。

我的代码中有一个小问题，我很高兴理解我的错误：

1）这是我的索引文件

import { combineReducers } from 'redux-immutable';
import { reducer as formReducer } from 'redux-form';
import appReducer from './appReducer';
import errorReducer from './errorReducer';
import loginReducer from './loginReducer';
import modalReducer from './modalReducer';
import changeRequestReducer from './changeRequestReducer';
import releaseReducer from './releaseReducer';
import releaseReviewReducer from './releaseReviewReducer';
import logoutReducer from './logoutReducer';
import customAvatarReducer from './customAvatarReducer';
import { USER_LOGOUT } from '../actions/logoutActions';

const rootReducer = (state, action) => {
  if (action.type === USER_LOGOUT) {
    const state = undefined;
  }

  return reducers(state, action);
};

const reducers = combineReducers({
  appReducer,
  errorReducer,
  loginReducer,
  changeRequestReducer,
  releaseReducer,
  modalReducer,
  releaseReviewReducer,
  form: formReducer,
  logoutReducer,
  customAvatarReducer,
  rootReducer,
});

export default reducers;

我尝试添加此内容：

Productcategories.fullpath

这是文件的树，

问题是我收到错误消息“您达到了最大调用堆栈大小”

我做错了什么？我不知道是否可能是这个问题，但我们正在使用Immutable.js

UPDATE

这是收到的错误

这是现在的索引文件

LEFT(Productcategories.Fullpath, CHARINDEX('/',ProductCategories.Fullpath + '/') - 1) as shortpath,

Answer 1

尝试更改

export default reducers;

到

export default rootReducer;

Answer 2

您只需要替换位线，请尝试以下代码。

const rootReducer = (state, action) => {
  if (action.type === USER_LOGOUT) {
    state = [];
  }

  return reducers(...state, action);
};
