Getting Data from a key in a REST response

I'm trying to populate a Refine MUI table with data from the Django Rest Framework API. The response from the API is in the following format: { "count": 41, "next": "http://localhost:8000/api/captures?_end=25&_start=25", "previous": null, "results": [ { "id": 4, ....... } ] } How do I get the data grid to use just the results array without rewriting the API?

Hi @BrockLanders. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To get the data grid to use just the results array from your Django Rest Framework API response without rewriting the API, you can customize the data provider in Refine. Here’s how you can do it: 1. Swizzle the Simple REST Data Provider: This allows you to modify the data provider to suit your API response format. 2. Modify the Data Provider: Customize the data provider to extract the results array from the API response. Here are the steps in detail: Step 1: Swizzle the Simple REST Data Provider Run the swizzle command in your project directory to customize the data provider:

npm run refine swizzle

npm run refine swizzle

Select @refinedev/simple-rest from the list of available data providers. Step 2: Modify the Data Provider Edit the /rest-data-provider/index.ts file to customize the data provider. You need to modify the getList method to extract the results array from the API response. Here is an example of how you can modify the getList method:

import { DataProvider } from "@refinedev/core";
import { fetchUtils } from "ra-core";

const apiUrl = "<https://api.your-django-api.com";>
const httpClient = fetchUtils.fetchJson;

const dataProvider: DataProvider = {
    getList: async (resource, params) => {
        const url = `${apiUrl}/${resource}`;
        const { json } = await httpClient(url);
        return {
            data: json.results,
            total: json.count,
        };
    },
    // Implement other methods as needed
};

export default dataProvider;

import { DataProvider } from "@refinedev/core";
import { fetchUtils } from "ra-core";

const apiUrl = "<https://api.your-django-api.com";>
const httpClient = fetchUtils.fetchJson;

const dataProvider: DataProvider = {
    getList: async (resource, params) => {
        const url = `${apiUrl}/${resource}`;
        const { json } = await httpClient(url);
        return {
            data: json.results,
            total: json.count,
        };
    },
    // Implement other methods as needed
};

export default dataProvider;

Step 3: Use the Customized Data Provider Pass the customized data provider to the dataProvider prop of the Refine component in your application:

import React from "react";
import { Refine } from "@refinedev/core";
import dataProvider from "./rest-data-provider";
const App = () => {
    return (
        <Refine
            dataProvider={dataProvider}
            /* ... other props ... */
        />
    );
};

export default App;

import React from "react";
import { Refine } from "@refinedev/core";
import dataProvider from "./rest-data-provider";
const App = () => {
    return (
        <Refine
            dataProvider={dataProvider}
            /* ... other props ... */
        />
    );
};

export default App;

Step 4: Use useDataGrid Hook Now you can use the useDataGrid hook to fetch and display the data in a MUI DataGrid component. Here is an example:

import React from "react";
import { useDataGrid, List } from "@refinedev/mui";
import { DataGrid, GridColDef } from "@mui/x-data-grid";

interface IPost {
    id: number;
    title: string;
    content: string;
    status: "published" | "draft" | "rejected";
}

const PostsList: React.FC = () => {
    const { dataGridProps } = useDataGrid<IPost>();

    const columns = React.useMemo<GridColDef<IPost>[]>(() => [
        { field: "id", headerName: "ID", type: "number", width: 75 },
        { field: "title", headerName: "Title", minWidth: 400, flex: 1 },
        { field: "status", headerName: "Status", width: 120 },
    ], []);

    return (
        <List>
            <DataGrid {...dataGridProps} columns={columns} autoHeight />
        </List>
    );
};

export default PostsList;

import React from "react";
import { useDataGrid, List } from "@refinedev/mui";
import { DataGrid, GridColDef } from "@mui/x-data-grid";

interface IPost {
    id: number;
    title: string;
    content: string;
    status: "published" | "draft" | "rejected";
}

const PostsList: React.FC = () => {
    const { dataGridProps } = useDataGrid<IPost>();

    const columns = React.useMemo<GridColDef<IPost>[]>(() => [
        { field: "id", headerName: "ID", type: "number", width: 75 },
        { field: "title", headerName: "Title", minWidth: 400, flex: 1 },
        { field: "status", headerName: "Status", width: 120 },
    ], []);

    return (
        <List>
            <DataGrid {...dataGridProps} columns={columns} autoHeight />
        </List>
    );
};

export default PostsList;

By following these steps, you can customize the data provider to extract the results array from your API response and use it to populate the MUI DataGrid in your Refine application.
