Clear data in useOne

How can I trigger clear data in useOne?

Hi @Thracez. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To clear data in useOne hook in refine, you can use the invalidateQueries method from the useQueryClient hook provided by the @tanstack/react-query library. Here's how you can do it:

import { useQueryClient } from "@tanstack/react-query";

const queryClient = useQueryClient();

queryClient.invalidateQueries(["custom-key"]);

import { useQueryClient } from "@tanstack/react-query";

const queryClient = useQueryClient();

queryClient.invalidateQueries(["custom-key"]);

However, to use this method effectively, you need to know the query key used by the useOne hook. If you don't know the query key, you can specify it when using the useOne hook:

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

useOne({
  resource: "posts",
  id: 1,
  queryOptions: {
    queryKey: ["posts", 1],
  },
});

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

useOne({
  resource: "posts",
  id: 1,
  queryOptions: {
    queryKey: ["posts", 1],
  },
});

Then, you can invalidate this specific query:

queryClient.invalidateQueries(["posts", 1]);

queryClient.invalidateQueries(["posts", 1]);

This will clear the data for this specific useOne query and trigger a refetch. Refine useCustom FAQ provides more information on how to invalidate queries in refine. Remember that refine automatically invalidates affected resources after mutations. If you want to manually control this behavior, you can use the invalidates prop in hooks like useForm to specify which query sets should be invalidated, or set it to false to handle invalidation manually. Refine Forms Guide - Invalidation provides more details on customizing invalidation behavior in refine. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai I want to clear useOne data on state change

kapa.ai•2mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- To clear useOne data on state change in refine, you can use a combination of the useQueryClient hook and the queryOptions property of useOne. Here's how you can achieve this: 1. First, import the necessary hooks:

import { useOne } from "@refinedev/core";
import { useQueryClient } from "@tanstack/react-query";

import { useOne } from "@refinedev/core";
import { useQueryClient } from "@tanstack/react-query";

2. In your component, set up your state and the useQueryClient:

const [state, setState] = useState(initialState);
const queryClient = useQueryClient();

const [state, setState] = useState(initialState);
const queryClient = useQueryClient();

3. Use the useOne hook with a specific query key:

const { data } = useOne({
  resource: "your-resource",
  id: "your-id",
  queryOptions: {
    queryKey: ["your-resource", "your-id", state],
  },
});

const { data } = useOne({
  resource: "your-resource",
  id: "your-id",
  queryOptions: {
    queryKey: ["your-resource", "your-id", state],
  },
});

4. Create an effect that will invalidate the query when the state changes:

useEffect(() => {
  queryClient.invalidateQueries(["your-resource", "your-id", state]);
}, [state, queryClient]);

useEffect(() => {
  queryClient.invalidateQueries(["your-resource", "your-id", state]);
}, [state, queryClient]);

This setup will cause the useOne data to be cleared and refetched whenever the state changes. It's important to note that this approach will trigger a new API request each time the state changes. If you want to avoid unnecessary API calls, you might want to consider using the enabled option in queryOptions to control when the query should run. For example:

const { data } = useOne({
  resource: "your-resource",
  id: "your-id",
  queryOptions: {
    queryKey: ["your-resource", "your-id", state],
    enabled: !!state, // Only run the query when state is truthy
  },
});

const { data } = useOne({
  resource: "your-resource",
  id: "your-id",
  queryOptions: {
    queryKey: ["your-resource", "your-id", state],
    enabled: !!state, // Only run the query when state is truthy
  },
});

This approach aligns with refine's data fetching principles as described in the Refine useOne documentation. Remember that refine uses TanStack Query under the hood, so you can leverage all of its features for fine-grained control over your data fetching and caching behavior. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai How can I set default filters in useTable?

kapa.ai•2mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- To set default filters in useTable hook in refine, you can use the filters.initial property. This allows you to specify the initial filter state when the table is first rendered. Here's how you can do it:

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

const { tableProps, filters } = useTable({
  filters: {
    initial: [
      {
        field: "name",
        operator: "contains",
        value: "Foo",
      },
    ],
  },
});

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

const { tableProps, filters } = useTable({
  filters: {
    initial: [
      {
        field: "name",
        operator: "contains",
        value: "Foo",
      },
    ],
  },
});

In this example, the table will initially be filtered to show only records where the "name" field contains "Foo". You can set multiple initial filters by adding more objects to the initial array:

filters: {
  initial: [
    {
      field: "name",
      operator: "contains",
      value: "Foo",
    },
    {
      field: "status",
      operator: "eq",
      value: "active",
    },
  ],
}

filters: {
  initial: [
    {
      field: "name",
      operator: "contains",
      value: "Foo",
    },
    {
      field: "status",
      operator: "eq",
      value: "active",
    },
  ],
}

It's important to note that these initial filters are not permanent. They will be cleared when the user changes the filter. If you want to set permanent filters that cannot be changed by the user, you should use the filters.permanent property instead. For more information on the available filter operators and structure, you can refer to the CrudFilters interface documentation. Additionally, if you're using Ant Design's Table component with refine, don't forget to add defaultFilteredValue to your <Table.Column> components to ensure the filter states sync correctly with the table:

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

// ...

<Table.Column
  dataIndex="name"
  title="Name"
  defaultFilteredValue={getDefaultFilter("name", filters, "contains")}
  // ...
/>

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

// ...

<Table.Column
  dataIndex="name"
  title="Name"
  defaultFilteredValue={getDefaultFilter("name", filters, "contains")}
  // ...
/>

This information is based on the Refine useTable documentation and Ant Design useTable documentation. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
