How is the correct way to have multiple dataProviders in react-admin?

问题

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

I have my App.js like this:

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;

And I have the dataproviders.js file:

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);
};

How it's the correct way?

I check this post:

回答1:

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);
};
