在 react-admin 中访问 redux store [英] In react-admin get access to redux store

问题描述

我的问题与 react-admin 存储库有关.

My question is related to react-admin repo.

我想在组件范围之外分派一个动作，以便做到这一点，我读过 我需要访问实际的 redux 存储本身，并直接分派，

I want to dispatch an action, outside of scope of a component, in order to do that, I've read that I need to get access to the actual redux store itself, and dispatch on in directly,

所以我知道 Admin 组件有一个 initialState 属性，但它只接受默认状态对象，而不是商店.所以我不能创建一个 store 并传入.

so I know that the Admin component has an initialState prop, but it only accepts default state object, not the store. So I can't make a store and pass it in.

我的问题是:

• 如何访问 Admin 组件的 redux 存储?
• 使用 Admin 作为我的主要应用组件时，如何在组件外分派操作?

• How do I access redux store of an Admin component?
• How can I dispatch an action outside of a component, when using Admin as my main app component?

我当前的应用条目如下所示:

my current app entry looks like this:

<AppLayoutDirection>
    <Admin
      title="My App"
      locale="en"
      dataProvider={dataProvider}
      authProvider={authProvider}
      i18nProvider={i18nProvider}
      theme={themeProvider}
      customSagas={customSagas}
      appLayout={AppLayout}
    >
      {DynamicResource}
    </Admin>
  </AppLayoutDirection>

推荐答案

当你说你需要在组件范围之外分派一个动作时，我想它是对过去分派的另一个动作的反应.

When you say that you need to dispatch an action outside the scope of a component, I suppose that it's in reaction to another action that was dispatched in the past.

在那种情况下，这就是 react-admin 所说的副作用.React-admin 使用 redux-saga 处理副作用.以下是创建自定义传奇的方法:

In that case, that's what react-admin calls a side effect. React-admin handles side effects using redux-saga. Here is how to create a custom saga:

// in src/bitcoinSaga.js
import { put, takeEvery } from 'redux-saga/effects';
import { showNotification } from 'react-admin';

export default function* bitcoinSaga() {
    yield takeEvery('BITCOIN_RATE_RECEIVED', function* () {
        yield put(showNotification('Bitcoin rate updated'));
    })
}

在组件中注册这个saga如下:

Register this saga in the <Admin> component as follows:

// in src/App.js
import React from 'react';
import { Admin } from 'react-admin';

import bitcoinSaga from './bitcoinSaga';

const App = () => (
    <Admin customSagas={[ bitcoinSaga ]} dataProvider={simpleRestProvider('http://path.to.my.api')}>
        ...
    </Admin>
);

export default App;

这在 react-admin 文档中有记录，在 <;管理员>章节.

This is documented in the react-admin documentation, in the <Admin> chapter.
