I just get one object from the server, but it's not retrieved by id, so I can't use useOne.

What do I use instead of useList in this case?

Hi @florent. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- If you need to fetch a single object from the server but can't use useOne because the retrieval isn't based on an ID, you have a few options in refine: 1. You can use useCustom hook which allows you to make custom API requests: 
const { data, isLoading } = useCustom({
  url: "your-endpoint",
  method: "get",
  config: {
    // Additional configuration if needed
  },
});
const { data, isLoading } = useCustom({
  url: "your-endpoint",
  method: "get",
  config: {
    // Additional configuration if needed
  },
});
This is the most flexible approach when you need to fetch data that doesn't follow the standard CRUD patterns. 2. You can still use useList with filters to get exactly one record: 
const { data, isLoading } = useList({
  resource: "your-resource",
  filters: [
    {
      field: "your-field",
      operator: "eq",
      value: "your-value",
    },
  ],
  pagination: {
    pageSize: 1,
  },
});

// Access the single item
const singleItem = data?.data[0];
const { data, isLoading } = useList({
  resource: "your-resource",
  filters: [
    {
      field: "your-field",
      operator: "eq",
      value: "your-value",
    },
  ],
  pagination: {
    pageSize: 1,
  },
});

// Access the single item
const singleItem = data?.data[0];
This approach is useful when you're filtering by a specific field to get a unique record as shown in the documentation. 3. If you're working with tables and need to handle relational data, you might want to check the approach used in the documentation where they use useMany for related data but access a specific item from the result as demonstrated here. The most appropriate choice depends on your specific use case and API structure. If you're making a completely custom request that doesn't fit refine's standard data provider methods, useCustom is likely your best option. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

Let me check the knowledge base for you again. One moment! :books: ---------------------- I see you're encountering an error when trying to use the useCustom hook. The error "Not implemented custom on data provider" indicates that your data provider doesn't have the custom method implemented, which is required for the useCustom hook to work. How to Fix This Issue The custom method is optional in data providers, and it seems your current data provider doesn't implement it. Here's how you can fix this: 1. Implement the custom method in your data provider: 
// Example of implementing the custom method in your data provider
const dataProvider = (url: string): DataProvider => ({
  // Your existing methods (getOne, getList, etc.)
  
  // Add the custom method implementation
  custom: async ({
    url,
    method,
    filters,
    sorters,
    payload,
    query,
    headers,
    meta,
  }) => {
    // Handle the request according to your API requirements
    const response = await fetch(`${baseUrl}/${url}`, {
      method,
      headers: {
        "Content-Type": "application/json",
        ...headers,
      },
      body: payload ? JSON.stringify(payload) : undefined,
    });
    
    const data = await response.json();
    
    return {
      data,
    };
  },
  
  getApiUrl: () => url,
});
// Example of implementing the custom method in your data provider
const dataProvider = (url: string): DataProvider => ({
  // Your existing methods (getOne, getList, etc.)
  
  // Add the custom method implementation
  custom: async ({
    url,
    method,
    filters,
    sorters,
    payload,
    query,
    headers,
    meta,
  }) => {
    // Handle the request according to your API requirements
    const response = await fetch(`${baseUrl}/${url}`, {
      method,
      headers: {
        "Content-Type": "application/json",
        ...headers,
      },
      body: payload ? JSON.stringify(payload) : undefined,
    });
    
    const data = await response.json();
    
    return {
      data,
    };
  },
  
  getApiUrl: () => url,
});
2. Use a data provider that already implements the custom method:
If you're using a package like @refinedev/simple-rest, it already implements the custom method as documented here. 3. Customize your data provider using swizzle: You can use the swizzle command to customize your data provider: 
   npm run refine swizzle
   
   npm run refine swizzle
Then select your data provider and add the custom method implementation as shown in the documentation. Example Error Case Looking at your code: 
const { data: customerGroups } = useCustom({
  url: 'customergroups/detail',
  method: 'get',
})
const { data: customerGroups } = useCustom({
  url: 'customergroups/detail',
  method: 'get',
})
This error occurs because the data provider you're using doesn't have the custom method implemented. This is similar to the issue mentioned in a GitHub issue about Hasura data provider, where the useCustom hook wasn't working due to missing implementation. Remember that the useCustom hook is designed for making custom API requests that don't fit into the standard CRUD operations, and it requires the data provider to implement the custom method as documented here. Let me know if you need more specific guidance based on which data provider you're using! ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

성공한 경우 리스트를 다시 호출해야 합니다. resource: 'membership/subscribers',

Let me check the knowledge base for you again. One moment! :books: ---------------------- I see you need to refresh the list of 'membership/subscribers' after successfully creating a record in 'membership/change'. In refine, you can handle this by using the invalidates property or by manually invalidating the resource using the useInvalidate hook. Here are two approaches to solve your issue: Option 1: Using the invalidates property 
const { onFinish, formLoading } = useForm({
  action: 'create',
  resource: 'membership/change',
  successNotification: (data) => {
    return {
      message: data?.data?.message,
      type: data?.data?.type,
    }
  },
  errorNotification: (data) => {
    return {
      message: data?.data?.message,
      type: data?.data?.type,
    }
  },
  onMutationError: (error, variables, context) => {
    if (error?.statusCode === 500) {
      alert('지금은 변경 할 수 없습니다.')
    }
  },
  onMutationSuccess: () => {
    handleClose()
  },
  // This will not work as expected since it will invalidate 'membership/change' resource
  invalidates: ["list"]
})
const { onFinish, formLoading } = useForm({
  action: 'create',
  resource: 'membership/change',
  successNotification: (data) => {
    return {
      message: data?.data?.message,
      type: data?.data?.type,
    }
  },
  errorNotification: (data) => {
    return {
      message: data?.data?.message,
      type: data?.data?.type,
    }
  },
  onMutationError: (error, variables, context) => {
    if (error?.statusCode === 500) {
      alert('지금은 변경 할 수 없습니다.')
    }
  },
  onMutationSuccess: () => {
    handleClose()
  },
  // This will not work as expected since it will invalidate 'membership/change' resource
  invalidates: ["list"]
})
Option 2: Using the useInvalidate hook (Recommended) This is the better approach for your case since you need to invalidate a different resource: 
import { useInvalidate } from "@refinedev/core";

// Inside your component
const invalidate = useInvalidate();
const { onFinish, formLoading } = useForm({
  action: 'create',
  resource: 'membership/change',
  successNotification: (data) => {
    return {
      message: data?.data?.message,
      type: data?.data?.type,
    }
  },
  errorNotification: (data) => {
    return {
      message: data?.data?.message,
      type: data?.data?.type,
    }
  },
  onMutationError: (error, variables, context) => {
    if (error?.statusCode === 500) {
      alert('지금은 변경 할 수 없습니다.')
    }
  },
  onMutationSuccess: () => {
    // Invalidate the subscribers list to trigger a refetch
    invalidate({
      resource: "membership/subscribers",
      invalidates: ["list"]
    });
    handleClose();
  },
})
import { useInvalidate } from "@refinedev/core";

// Inside your component
const invalidate = useInvalidate();
const { onFinish, formLoading } = useForm({
  action: 'create',
  resource: 'membership/change',
  successNotification: (data) => {
    return {
      message: data?.data?.message,
      type: data?.data?.type,
    }
  },
  errorNotification: (data) => {
    return {
      message: data?.data?.message,
      type: data?.data?.type,
    }
  },
  onMutationError: (error, variables, context) => {
    if (error?.statusCode === 500) {
      alert('지금은 변경 할 수 없습니다.')
    }
  },
  onMutationSuccess: () => {
    // Invalidate the subscribers list to trigger a refetch
    invalidate({
      resource: "membership/subscribers",
      invalidates: ["list"]
    });
    handleClose();
  },
})
This approach uses the useInvalidate hook to manually invalidate the 'membership/subscribers' resource after a successful mutation, which will trigger a refetch of the list data as documented here. The invalidates: ["list"] parameter specifies that you want to invalidate the list queries for that resource, which will cause any components using useList with that resource to refetch their data. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

Let me check the knowledge base for you again. One moment! :books: ---------------------- 네, 오류 메시지에서 알려주는 대로 invalidate 함수를 사용하기 전에 useInvalidate 훅을 import하고 호출해야 합니다. 이 오류는 invalidate 함수가 정의되지 않았기 때문에 발생합니다. 다음과 같이 코드를 수정해보세요: 
import { useInvalidate } from "@refinedev/core";

// 컴포넌트 내부에서
const invalidate = useInvalidate();

const { onFinish, formLoading } = useForm({
  action: 'create',
  resource: 'membership/change',
  // 다른 속성들...
  onMutationSuccess: () => {
    invalidate({
      resource: 'membership/subscribers',
      invalidates: ['list'],
    });
    handleClose();
  },
})
import { useInvalidate } from "@refinedev/core";

// 컴포넌트 내부에서
const invalidate = useInvalidate();

const { onFinish, formLoading } = useForm({
  action: 'create',
  resource: 'membership/change',
  // 다른 속성들...
  onMutationSuccess: () => {
    invalidate({
      resource: 'membership/subscribers',
      invalidates: ['list'],
    });
    handleClose();
  },
})
useInvalidate 훅은 refine에서 특정 리소스의 상태를 무효화하는 데 사용됩니다. 이 훅을 사용하면 mutation이 성공한 후에 다른 리소스의 데이터를 다시 불러올 수 있습니다. useInvalidate 문서에서 자세한 내용을 확인할 수 있습니다. 위 코드에서는 membership/change 리소스에 대한 mutation이 성공한 후 membership/subscribers 리소스의 list 쿼리를 무효화하여 데이터를 다시 불러오도록 합니다. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
