Hi @coops8. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Yes, you can implement the export feature using useExport and filter the data based on the created_at field. To achieve this, you can use the mapData property of the useExport hook to filter the data before exporting it. Here's an example of how you can use the mapData property to filter the data based on a date range:

import { useExport } from "@refinedev/core";

interface IPost {
  id: number;
  title: string;
  created_at: string;
}

const startDate = new Date("2022-01-01");
const endDate = new Date("2022-01-31");

export const PostList: React.FC = () => {
  const { triggerExport } = useExport<IPost>({
    mapData: (item) => {
      const createdAt = new Date(item.created_at);
      if (createdAt >= startDate && createdAt <= endDate) {
        return item;
      }
      return null;
    },
  });

  return (
    <div>
      <button onClick={triggerExport}>Export Button</button>
      ...
    </div>
  );
};

import { useExport } from "@refinedev/core";

interface IPost {
  id: number;
  title: string;
  created_at: string;
}

const startDate = new Date("2022-01-01");
const endDate = new Date("2022-01-31");

export const PostList: React.FC = () => {
  const { triggerExport } = useExport<IPost>({
    mapData: (item) => {
      const createdAt = new Date(item.created_at);
      if (createdAt >= startDate && createdAt <= endDate) {
        return item;
      }
      return null;
    },
  });

  return (
    <div>
      <button onClick={triggerExport}>Export Button</button>
      ...
    </div>
  );
};

In this example, we're filtering the data based on the created_at field, only including items that fall within the specified date range (between startDate and endDate). The mapData function returns the item if it falls within the range, and null otherwise. For more information on the useExport hook and its properties, refer to the useExport documentation (https://refine.dev/docs/api-reference/core/hooks/import-export/useExport/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

how can i export based on the selected ids from the list of ids @kapa.ai

Let me check the knowledge base for you. One moment! :books: ---------------------- You can export data based on the selected IDs using the useExport hook and the mapData property. First, you need to manage the selected IDs using state and handle the selection changes. Then, you can use the mapData property to filter the data based on the selected IDs. Here's an example:

import { useExport } from "@refinedev/core";

interface IPost {
  id: number;
  title: string;
}

export const PostList: React.FC = () => {
  const [selectedIds, setSelectedIds] = React.useState<number[]>([]);

  const handleSelectChange = (selectedIds: number[]) => {
    setSelectedIds(selectedIds);
  };

  const { triggerExport } = useExport<IPost>({
    mapData: (item) => {
      if (selectedIds.includes(item.id)) {
        return item;
      }
      return null;
    },
  });

  // Render your list and selection components here, and pass the handleSelectChange function to handle selection changes

  return (
    <div>
      <button onClick={triggerExport}>Export Selected</button>
      ...
    </div>
  );
};

import { useExport } from "@refinedev/core";

interface IPost {
  id: number;
  title: string;
}

export const PostList: React.FC = () => {
  const [selectedIds, setSelectedIds] = React.useState<number[]>([]);

  const handleSelectChange = (selectedIds: number[]) => {
    setSelectedIds(selectedIds);
  };

  const { triggerExport } = useExport<IPost>({
    mapData: (item) => {
      if (selectedIds.includes(item.id)) {
        return item;
      }
      return null;
    },
  });

  // Render your list and selection components here, and pass the handleSelectChange function to handle selection changes

  return (
    <div>
      <button onClick={triggerExport}>Export Selected</button>
      ...
    </div>
  );
};

In this example, we're using the mapData function to filter the data based on the selected IDs. The function returns the item if its ID is included in the selectedIds array, and null otherwise. For more information on the useExport hook and its properties, refer to the useExport documentation (https://refine.dev/docs/api-reference/core/hooks/import-export/useExport/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
