Hi @Chrystian Ferreira. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Based on the extracts provided, there isn't specific information on how to directly change pages using the useSelect hook with pagination in refine. The extracts focus on the configuration changes for pagination in useSelect from version 3.x.x to 4.x.x, specifically mentioning the transition to enabling server-side pagination by setting the pagination.mode prop to "server" and replacing the sort prop with sorters. However, they do not detail methods or functions for navigating between pages. For detailed guidance on implementing pagination and navigating between pages with useSelect or any other refine hooks, I recommend consulting the official refine documentation or community resources for examples and best practices. The refine documentation is a comprehensive source that likely covers pagination handling in depth, including examples of how to implement page navigation. Here's a general approach based on refine's patterns for hooks that involve pagination, although it's important to note this is not directly extracted from the provided information:
// Hypothetical example based on refine patterns
const { data, pagination } = useSelect({
resource: "your-resource",
pagination: {
current: 1, // Current page
pageSize: 10, // Items per page
},
// Other configurations...
});

// Function to change page
const changePage = (newPage) => {
// Update the pagination state here
// This might involve setting a new state for 'current' and re-fetching data
};
// Hypothetical example based on refine patterns
const { data, pagination } = useSelect({
resource: "your-resource",
pagination: {
current: 1, // Current page
pageSize: 10, // Items per page
},
// Other configurations...
});

// Function to change page
const changePage = (newPage) => {
// Update the pagination state here
// This might involve setting a new state for 'current' and re-fetching data
};
For useSelect and pagination specifically, you would typically manage the current page state outside of the useSelect hook and then pass the updated state (e.g., the next page number) into the hook to fetch data for the next page. This might involve using React state hooks like useState to keep track of the current page and providing UI elements for the user to navigate between pages (e.g., next and previous buttons). Since the exact method for changing pages with useSelect wasn't detailed in the extracts, please refer to the refine documentation (https://refine.dev/docs/) for the most accurate and up-to-date information. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai Can you please provide implementation details for the 'changePage' function in your last answer?

Let me check the knowledge base for you. One moment! :books: ---------------------- Hmm, I don't know enough to give you a confident answer yet. The extracts provided do not include specific details on implementing a changePage function using the useSelect hook in refine, nor do they offer direct examples of pagination logic or functions for navigating between pages. For accurate and detailed information on implementing pagination, including changing pages in refine applications, I recommend consulting the official refine documentation. The documentation is likely to provide comprehensive guides, examples, and API references that cover pagination and navigation between pages in depth, which would be essential for implementing a changePage function correctly. You can start exploring more about refine and its pagination capabilities here: refine documentation (https://refine.dev/docs/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

Is this even possible? @kapa.ai I have managed to develop a solution but I am struggling to make the loading state work. isLoading, that comes from queryResult, is true on initial load but then when I change pages it never changes from false to true. Is this a possible bug? Here is my current code:
const SelectStore = ({ onChange }: SelectStoreProps) => {
const [currentPage, setCurrentPage] = useState(1);
const [isLoading, setIsLoading] = useState(true);
const { selectProps: storeSelectProps, queryResult } = useSelect({
resource: LOCALE_STORE_RESOURCE,
optionLabel: "name",
pagination: {
current: currentPage,
pageSize: 5,
mode: "server",
},
});
const {
data: storeSelectData,
isRefetching,
isLoading: queryResultIsLoading,
} = queryResult;
console.log({ isRefetching, queryResultIsLoading }); // both always false
const goToNextPage = () => {
setIsLoading(true);
setCurrentPage(currentPage + 1);
};
const goToPreviousPage = () => {
setIsLoading(true);
setCurrentPage(currentPage - 1);
};

useEffect(() => {
setIsLoading(false);
}, [storeSelectProps.options]);

return (
<Select
{...storeSelectProps}
placeholder="Revendas"
onChange={onChange}
dropdownRender={(menu) => (
<Space direction="vertical">
{currentPage > 1 && (
<Button onClick={goToPreviousPage}>
Anterior
</Button>
)}
{isLoading ? (
<>
<Skeleton />
</>
) : (
<>{menu}</>
)}
{currentPage < storeSelectData?.pages && (
<Button onClick={goToNextPage}>
Próximo
</Button>
)}
{!isLoading && currentPage === storeSelectData?.pages && (
<p>Não há mais revendas.</p>
)}
</Space>
)}
/>
);
};
const SelectStore = ({ onChange }: SelectStoreProps) => {
const [currentPage, setCurrentPage] = useState(1);
const [isLoading, setIsLoading] = useState(true);
const { selectProps: storeSelectProps, queryResult } = useSelect({
resource: LOCALE_STORE_RESOURCE,
optionLabel: "name",
pagination: {
current: currentPage,
pageSize: 5,
mode: "server",
},
});
const {
data: storeSelectData,
isRefetching,
isLoading: queryResultIsLoading,
} = queryResult;
console.log({ isRefetching, queryResultIsLoading }); // both always false
const goToNextPage = () => {
setIsLoading(true);
setCurrentPage(currentPage + 1);
};
const goToPreviousPage = () => {
setIsLoading(true);
setCurrentPage(currentPage - 1);
};

useEffect(() => {
setIsLoading(false);
}, [storeSelectProps.options]);

return (
<Select
{...storeSelectProps}
placeholder="Revendas"
onChange={onChange}
dropdownRender={(menu) => (
<Space direction="vertical">
{currentPage > 1 && (
<Button onClick={goToPreviousPage}>

</Button>
)}
{isLoading ? (
<>
<Skeleton />
</>
) : (
<>{menu}</>
)}
{currentPage < storeSelectData?.pages && (
<Button onClick={goToNextPage}>
Próximo
</Button>
)}
{!isLoading && currentPage === storeSelectData?.pages && (
<p>Não há mais revendas.</p>
)}
</Space>
)}
/>
);
};

Let me check the knowledge base for you. One moment! :books: ---------------------- Based on the provided code and the information from the extracts, it seems like you're trying to manage the loading state manually with a separate useState hook (isLoading, setIsLoading). However, refine provides a loading state directly from the queryResult object (queryResultIsLoading in your code). The queryResultIsLoading should be true while the data is being fetched, including when you're changing pages. If it's not changing to true when changing pages, it might be a bug or an issue with the implementation. However, there's a known issue with refine where the loading state doesn't change to true during revalidation of the cache, as mentioned in the Github Issue (closed): [BUG] Caching does not work with useTable due to the returned loading attribute set to true during re-validation (https://github.com/refinedev/refine/issues/1321). This issue is specifically about useTable, but it might be related to your issue with useSelect. In the issue, it's suggested to rely on status or isSuccess instead of isFetching (which is also true while revalidating cache). However, in your case, you're using isLoading from queryResult, which should be equivalent to isFetching. If you're still facing the issue, I recommend creating a new issue in the refine Github repository (https://github.com/pankod/refine/issues) providing all the necessary details. The maintainers and the community can help you identify if it's a bug or an issue with the implementation. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

BRUH. It was because this was in my useSelect:
queryOptions: {
cacheTime: 10000,
keepPreviousData: true,
},
queryOptions: {
cacheTime: 10000,
keepPreviousData: true,
},
This made isRefetching changing from false to true not possible for 10s after changing pages @kapa.ai How can I assert that the onSearch function was called using vitest?

Let me check the knowledge base for you. One moment! :books: ---------------------- Based on the provided extracts, you can use the jest testing library to create a mock function and assert that it was called. Here's an example of how you might do this:
import { fireEvent, render } from "@testing-library/react";
import { TestComponent } from "./TestComponent"; // replace with your component

test("calls onSearch function when button is clicked", () => {
const onSearch = jest.fn();

const { getByText } = render(<TestComponent onSearch={onSearch} />);

fireEvent.click(getByText("Search")); // replace "Search" with the text on your button

expect(onSearch).toHaveBeenCalled();
});
import { fireEvent, render } from "@testing-library/react";
import { TestComponent } from "./TestComponent"; // replace with your component

test("calls onSearch function when button is clicked", () => {
const onSearch = jest.fn();

const { getByText } = render(<TestComponent onSearch={onSearch} />);

fireEvent.click(getByText("Search")); // replace "Search" with the text on your button

expect(onSearch).toHaveBeenCalled();
});
In this example, jest.fn() is used to create a mock function. This mock function is passed as a prop to the component being tested. After simulating a click event on the button, expect(onSearch).toHaveBeenCalled() is used to assert that the onSearch function was called. Please replace TestComponent and "Search" with your actual component and button text. This is a general example and might need to be adjusted based on your specific use case and testing setup. For more detailed information on testing in React, you can refer to the React Testing Library documentation (https://testing-library.com/docs/react-testing-library/intro/). Please note that the provided extracts do not contain specific information about vitest. The example above uses jest and @testing-library/react, which are commonly used for testing React components. If you're using vitest, you might need to adjust the example to fit with vitest's API and usage. For more information on using vitest, please refer to the vitest documentation (https://vitest.dev/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
