在 react-admin 中拥有多个 dataProvider 的正确方法是什么?

问题描述

我正在尝试在 react-admin 项目中使用多个数据提供者，但出现错误:

I'm trying to use multiple dataproviders in a react-admin project but I have an error:

Warning: Missing translation for key: "dataProvider is not a function"
function.console.(anonymous function) @ index.js:1452

我的 App.js 是这样的:

import React from 'react';
import { render } from 'react-dom';
import { Admin, Resource } from 'react-admin';
import dataProviders from './service/dataproviders';
import UserList1,  from './users1';
import UserList2,  from './users2';

const App = () => (
  render(
    <Admin dataProvider={dataProviders}>
      <Resource name="users1" list={UserList1} />
      <Resource name="users2" list={UserList2} />
    </Admin>,
    document.getElementById('root'),
  )
);

export default App;

我有 dataproviders.js 文件:

import simpleRestProvider from 'ra-data-simple-rest';

const dataProviders = [
  { dataProvider: simpleRestProvider('http://path.to.foo.api1'), resources: ['users1'] },
  { dataProvider: simpleRestProvider('http://path.to.foo.api2'), resources: ['users2'] },
];

export default (type, resource, params) => {
  const dataProvider = dataProviders.find(dp => dp.resources.includes(resource));
  return dataProvider(type, resource, params);
};

正确的方法是怎样的?

我查看了这篇文章:

是否可以有多个 dataProvider 进行反应-管理员?

推荐答案

您不是在调用您找到的 dataProvider，而是从您的数组调用映射对象.你可以像这样修复它:

You're not calling the dataProvider you found, you're calling the mapping object from your array. You can fix it like this:

import simpleRestProvider from 'ra-data-simple-rest';

const dataProviders = [
  { dataProvider: simpleRestProvider('http://path.to.foo.api1'), resources: ['users1'] },
  { dataProvider: simpleRestProvider('http://path.to.foo.api2'), resources: ['users2'] },
];

export default (type, resource, params) => {
  const dataProviderMapping = dataProviders.find(dp => dp.resources.includes(resource));
  return dataProviderMapping.dataProvider(type, resource, params);
};
