具有react-admin v 3.9.6的多个dataProvider

问题描述

嗨，我想使用superDataProvider在v3中使用2个dataProvider。并由资源名称决定。我遵循相同的示例，但没有成功（我也尝试使用dataProviderFactory进行演示）

import jsonServerProvider from 'ra-data-json-server';
import restProvider from 'ra-data-simple-rest';

const dataProviderRest = restProvider('https://myapi.com');
const dataProviderjson = jsonServerProvider('https://jsonplaceholder.typicode.com');

const superDataProvider = (type: any,resource: any,params: any) => {
    if (resource === 'tags') {
        return dataProviderRest;
    }
    return dataProviderjson;
}

export default superDataProvider;

解决方法

文档说dataProvider必须具有以下方法：

const dataProvider = {
    getList:    (resource,params) => Promise,getOne:     (resource,getMany:    (resource,getManyReference: (resource,create:     (resource,update:     (resource,updateMany: (resource,delete:     (resource,deleteMany: (resource,}

因此，我认为可以使用类似的方法

import jsonServerProvider from 'ra-data-json-server';
import restProvider from 'ra-data-simple-rest';

const dataProviderRest = restProvider('https://myapi.com');
const dataProviderJson = jsonServerProvider('https://jsonplaceholder.typicode.com');

export const superDataProvider = {
    ...dataProviderJson,// Preserve methods that are not extended

    update: (resource,params) => {
        if (resource === 'tags') {
            return dataProviderRest.update(resource,params);
        }
        return dataProviderJson.update(resource,params);
    }
}
