为 redux-undo 初始化历史记录不会填充过去或未来

Question

我在使用 redux-undo 为可撤消的 reducer 初始化历史记录时遇到问题。 These are the directions I followed. The present state is loaded, but the past and future states are not loaded. I'm hosting the code here, https://murmuring-shelf-40601.herokuapp.com 我在中间件中添加了一个记录器，因此如果您打开控制台，您将看到 undo/redu 历史记录。

这是我的商店。我将它包装在一个承诺中，因为我正在从服务中获取历史记录，但我已将初始历史记录硬编码到 initialHistory 对象以进行测试。 herokuapp.com 上托管的代码正在获取实时数据。

import { get } from 'axios'
import { applyMiddleware, createStore } from 'redux'
import { createLogger } from "redux-logger";
import thunk from "redux-thunk"
import { combineReducers } from 'redux'
import Promise from 'promise';
import UndoableNoteList from '../reducers/UndoableNoteList/UndoableNoteList'

var store = new Promise(function (resolve, reject) {
    get("/server/load-notes").catch((response)=> {
        const initialHistory = {
            "UndoableNoteList": {
                "present": {
                    "list": [
                        {
                            "id": "f5230212-8a46-4a48-91c1-5fadd4e4ae5e",
                            "text": "123123123123123123213"
                        },
                        {
                            "id": "bd4fe681-5071-4dd8-99e8-f46825eee866",
                            "text": "Jdk123123123123123123123sjdmd"
                        }
                    ]
                },
                "past": [
                    {
                        "list": [
                            {
                                "id": "c60dc097-00ea-4dfa-9532-de44b25b1a7a",
                                "text": "Eggs"
                            },
                            {
                                "id": "f61997bc-c8d7-46d7-836f-44af50a1a70d",
                                "text": "Milk"
                            },
                            {
                                "id": "ab932fae-8588-4b20-a6c4-620c6a4345f7",
                                "text": "Cheese"
                            }
                        ]
                    },
                    {
                        "list": [
                            {
                                "id": "f5230212-8a46-4a48-91c1-5fadd4e4ae5e",
                                "text": "Hhhfg"
                            },
                            {
                                "id": "bd4fe681-5071-4dd8-99e8-f46825eee866",
                                "text": "Jdksjdmd"
                            }
                        ]
                    }
                ],
                "future": []
            }
        };
        const reducer = combineReducers({UndoableNoteList: UndoableNoteList});
        const middleware = applyMiddleware(thunk, createLogger());
        const store = createStore(reducer, initialHistory, middleware);
        resolve(store);
    });
});

export default store

这是我的可撤销减速器。

更新 - 这个减速器有一些问题。不要将其用作参考。

这里是 index.js 我设置提供商的地方

import React from 'react';
import ReactDOM from 'react-dom';

import './index.css';
import {Router, Route, IndexRoute, hashHistory } from "react-router"
import Home from './pages/Home/Home';
import ListView from './pages/ListView/ListView'
import ListAdd from './pages/ListAdd/ListAdd'

import store from './store/Store'

store.then((store)=> {
    ReactDOM.render(
        <Provider store={store}>
            <Router history={hashHistory}>
                <Route path="/" component={Layout}>
                    <IndexRoute component={Home} name="Home"></IndexRoute>
                    <Route path="/view-notes" component={ListView} name="ViewNotes"></Route>
                    <Route path="/add-note" component={ListAdd} name="AddNote"></Route>

Answer 1

我将 redux-undo 库从 0.6.1 更新为 1.0.0-beta7，现在可以正确填充历史记录

为 redux-undo 初始化历史记录不会填充过去或未来

Initializing history for redux-undo isn't populating past or future

undo-redo
