How do I draw a datagrid when there is an array under the object?

When you get /nature resource The data comes down as "products": [{id:1, name: fff}, {id:2, name: dddd}]. In this case, how can I draw the array in products in datagrid?

Hi @florent. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To draw a DataGrid when you have an array nested under an object in your API response, you can use the useDataGrid hook from refine along with Material UI's DataGrid component. Here's how you can approach this: 1. First, define your columns to match the structure of your data:

const columns: GridColDef[] = [
  { field: 'id', headerName: 'ID', width: 70 },
  { field: 'name', headerName: 'Name', width: 130 },
];

const columns: GridColDef[] = [
  { field: 'id', headerName: 'ID', width: 70 },
  { field: 'name', headerName: 'Name', width: 130 },
];

2. Then, use the useDataGrid hook to fetch and process your data:

import { useDataGrid } from "@refinedev/mui";
import { DataGrid } from "@mui/x-data-grid";

const ProductList: React.FC = () => {
  const { dataGridProps } = useDataGrid({
    resource: "nature",
    meta: {
      fields: ["products.id", "products.name"],
    },
  });

  return (
    <DataGrid
      {...dataGridProps}
      columns={columns}
      rows={dataGridProps.rows?.flatMap((item) => item.products) || []}
    />
  );
};

import { useDataGrid } from "@refinedev/mui";
import { DataGrid } from "@mui/x-data-grid";

const ProductList: React.FC = () => {
  const { dataGridProps } = useDataGrid({
    resource: "nature",
    meta: {
      fields: ["products.id", "products.name"],
    },
  });

  return (
    <DataGrid
      {...dataGridProps}
      columns={columns}
      rows={dataGridProps.rows?.flatMap((item) => item.products) || []}
    />
  );
};

In this example: - We use the useDataGrid hook to fetch data from the "nature" resource. - We specify the fields we want to fetch in the meta option. - In the rows prop of the DataGrid, we use flatMap to flatten the nested "products" array. This approach will allow you to display the nested "products" array in your DataGrid. For more detailed information on using DataGrid with refine, you can refer to the Material UI DataGrid documentation. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

 return (
    <List>
      <DataGrid
        {...dataGridProps}
        rows={dataGridProps.rows?.flatMap((item) => item.products) || []}
        columns={columns}
        getRowHeight={() => 100}
      />
    </List>
  );
}

 return (
    <List>
      <DataGrid
        {...dataGridProps}
        rows={dataGridProps.rows?.flatMap((item) => item.products) || []}
        columns={columns}
        getRowHeight={() => 100}
      />
    </List>
  );
}

TypeError: _dataGridProps_rows.flatMap is not a function

Let me check the knowledge base for you again. One moment! :books: ---------------------- I apologize for the confusion in my previous answer. The error you're encountering suggests that dataGridProps.rows is not an array as expected. Let's modify the approach to handle this situation correctly. Based on the error message, it seems that the structure of your data might be different from what we initially assumed. Let's try to resolve this issue: 1. First, let's check the structure of your data:

const { dataGridProps } = useDataGrid({
  resource: "nature",
});

console.log(dataGridProps.rows);

const { dataGridProps } = useDataGrid({
  resource: "nature",
});

console.log(dataGridProps.rows);

This will help you understand the exact structure of the data you're receiving. 2. If dataGridProps.rows is already the array of products you want to display, you don't need to use flatMap. Instead, you can use it directly:

return (
  <List>
    <DataGrid
      {...dataGridProps}
      columns={columns}
      getRowHeight={() => 100}
    />
  </List>
);

return (
  <List>
    <DataGrid
      {...dataGridProps}
      columns={columns}
      getRowHeight={() => 100}
    />
  </List>
);

3. If dataGridProps.rows is an object with a products property that is an array, you can modify it like this:

return (
  <List>
    <DataGrid
      {...dataGridProps}
      rows={dataGridProps.rows?.products || []}
      columns={columns}
      getRowHeight={() => 100}
    />
  </List>
);

return (
  <List>
    <DataGrid
      {...dataGridProps}
      rows={dataGridProps.rows?.products || []}
      columns={columns}
      getRowHeight={() => 100}
    />
  </List>
);

4. If you're still encountering issues, you might need to transform the data before passing it to the DataGrid. You can do this using the useMany hook:

import { useMany } from "@refinedev/core";
import { useDataGrid, List } from "@refinedev/mui";
import { DataGrid } from "@mui/x-data-grid";

const ProductList: React.FC = () => {
  const { dataGridProps } = useDataGrid({
    resource: "nature",
  });

  const { data: productData } = useMany({
    resource: "products",
    ids: dataGridProps.rows?.map((item) => item.id) || [],
    queryOptions: {
      enabled: !!dataGridProps.rows,
    },
  });
return (
    <List>
      <DataGrid
        {...dataGridProps}
        rows={productData?.data || []}
        columns={columns}
        getRowHeight={() => 100}
      />
    </List>
  );
};

import { useMany } from "@refinedev/core";
import { useDataGrid, List } from "@refinedev/mui";
import { DataGrid } from "@mui/x-data-grid";

const ProductList: React.FC = () => {
  const { dataGridProps } = useDataGrid({
    resource: "nature",
  });

  const { data: productData } = useMany({
    resource: "products",
    ids: dataGridProps.rows?.map((item) => item.id) || [],
    queryOptions: {
      enabled: !!dataGridProps.rows,
    },
  });
return (
    <List>
      <DataGrid
        {...dataGridProps}
        rows={productData?.data || []}
        columns={columns}
        getRowHeight={() => 100}
      />
    </List>
  );
};

This approach fetches the product data separately and uses it for the rows. For more detailed information on handling complex data structures with refine and Material UI DataGrid, you can refer to the useDataGrid documentation. If you're still facing issues, please provide more details about the structure of your API response, and I'll be happy to help further. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
