useSelect not working , giving error G.mpa.data is not a function

const { selectProps } = useSelect<ICategory>({ resource: "categories", }); My api response is { "count": 4, "next": null, "previous": null, "results": [ { "id": 1, "organization_name": "test2", }, { "id": 2, "organization_name": "test2", }, { "id": 3, "organization_name": "test2", }, { "id": 4, "organization_name": "test2", } ] }

Hi @jash.s. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- The error you're encountering might be due to the structure of the response from your API. The useSelect hook in Refine expects the data to be in a specific format. According to the documentation (https://refine.dev/docs/ui-integrations/ant-design/hooks/use-select#resource-), the resource prop in useSelect will be passed to the getList method from the dataProvider as a parameter via the useList hook. The parameter is usually used as an API endpoint path but it all depends on how you handle the resource in the getList method. In your case, the useSelect hook might be expecting an array directly, but it's getting an object with properties like count, next, previous, and results. The actual data seems to be in the results array. You might need to adjust your data provider to ensure that the data returned by the getList method is in the format expected by useSelect. Here is an example of how the response should be structured:

return {
  data: data.results,
  total: data.count,
};

return {
  data: data.results,
  total: data.count,
};

This way, useSelect will receive the data in the format it expects. If you're still having trouble, you might want to check out the Refine documentation (https://refine.dev/docs) for more information on how to use hooks and handle data. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai but i want the count para as well

Let me check the knowledge base for you. One moment! :books: ---------------------- The useSelect hook in Refine doesn't directly provide a way to access the count parameter from the response. It's primarily used for fetching and displaying a list of items, and it expects the data to be an array of those items. However, you can create a custom hook that uses the useQuery hook from react-query (which is used internally by Refine) to fetch the data and provide both the results and count. Here's an example of how you might do this:

import { useQuery } from "react-query";
import axios from "axios";

const useCustomSelect = (resource: string) => {
  const { data, isLoading } = useQuery(resource, () =>
    axios.get(`your-api-url/${resource}`).then((res) => res.data)
  );

  return {
    selectProps: {
      data: data?.results,
      loading: isLoading,
    },
    count: data?.count,
  };
};

import { useQuery } from "react-query";
import axios from "axios";

const useCustomSelect = (resource: string) => {
  const { data, isLoading } = useQuery(resource, () =>
    axios.get(`your-api-url/${resource}`).then((res) => res.data)
  );

  return {
    selectProps: {
      data: data?.results,
      loading: isLoading,
    },
    count: data?.count,
  };
};

In this example, useCustomSelect fetches the data and returns an object with selectProps (which you can spread into useSelect) and count. You can use it like this:

const { selectProps, count } = useCustomSelect("categories");

const { selectProps, count } = useCustomSelect("categories");

Please replace "your-api-url" with your actual API URL. Remember, this is just an example and might need to be adjusted based on your actual API and application setup. For more information, you can refer to the Refine documentation (https://refine.dev/docs) and the React Query documentation (https://react-query.tanstack.com/overview). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

is there something which can be achiveved by useSelect Internally ? @kapa.ai \

Let me check the knowledge base for you. One moment! :books: ---------------------- The useSelect hook in Refine is designed to fetch and manage data for select components. It doesn't directly provide a way to access additional parameters like count from the response. It's primarily used for fetching and displaying a list of items, and it expects the data to be an array of those items. However, you can extend the functionality of useSelect by wrapping it in a custom hook and adding additional features as needed. This would involve using the useList hook, which is used internally by useSelect, and customizing it to also return the count parameter. Here's an example of how you might do this:

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

const useCustomSelect = (resource: string) => {
  const { data, isLoading } = useList({
    resource: resource,
  });

  return {
    selectProps: {
      data: data?.results,
      loading: isLoading,
    },
    count: data?.count,
  };
};

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

const useCustomSelect = (resource: string) => {
  const { data, isLoading } = useList({
    resource: resource,
  });

  return {
    selectProps: {
      data: data?.results,
      loading: isLoading,
    },
    count: data?.count,
  };
};

In this example, useCustomSelect fetches the data and returns an object with selectProps (which you can spread into useSelect) and count. You can use it like this:

const { selectProps, count } = useCustomSelect("categories");

const { selectProps, count } = useCustomSelect("categories");

i want to work it out with this format , if i do not get count then its fine { "count": 4, "next": null, "previous": null, "results": [ { "id": 1, "organization_name": "test2", }, { "id": 2, "organization_name": "test2", }, { "id": 3, "organization_name": "test2", }, { "id": 4, "organization_name": "test2", } @kapa.ai

Let me check the knowledge base for you. One moment! :books: ---------------------- If you want to work with the useSelect hook and your API response is in the format you provided, you need to adjust your data provider to ensure that the data returned by the getList method is in the format expected by useSelect. The useSelect hook expects the data to be an array of items. In your case, the actual data is in the results array. So, you need to return data.results from your getList method in your data provider. Here's an example of how the response should be structured:

return {
  data: data.results,
  total: data.count,
};

return {
  data: data.results,
  total: data.count,

Hello @jash.s, useSelect works as expected in our examples. if you provide reproducible example for us to debug, we would happy to help
