Refetching data on state change

const { data: scenarios, isLoading, refetch } = useOne({
resource: "scenarios/course",
id,
});
const { data: scenarios, isLoading, refetch } = useOne({
resource: "scenarios/course",
id,
});
Here is my data fetch code inside my functional component. How can I make the useOne hook get called again using a useEffect, while also making that data that is fetched available to the rest of the component.

Hi @.chasel. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- You can use the useEffect hook to trigger a refetch of your data when certain dependencies change. The useOne hook returns a refetch function that you can call to trigger a new request. Here's how you can do it:
import { useEffect } from "react";
import { useOne } from "@refinedev/core";

const MyComponent = () => {
const { data: scenarios, isLoading, refetch } = useOne({
resource: "scenarios/course",
id,
});

useEffect(() => {
refetch();
}, [/* your dependencies here */]);

// rest of your component
};
import { useEffect } from "react";
import { useOne } from "@refinedev/core";

const MyComponent = () => {
const { data: scenarios, isLoading, refetch } = useOne({
resource: "scenarios/course",
id,
});

useEffect(() => {
refetch();
}, [/* your dependencies here */]);

// rest of your component
};
In the useEffect hook, you can specify the dependencies that, when changed, will trigger the useEffect callback. In this callback, you call the refetch function to fetch the data again. The fetched data (scenarios in your case) is available to the rest of the component as it's stored in the state of the component. You can use it directly in your JSX or in other hooks and functions within your component. Remember to handle loading and error states using the isLoading variable and the isError variable (not shown in your code but available from useOne), respectively. For more information, refer to the useOne documentation (https://refine.dev/docs/api-reference/core/hooks/data/useOne/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai How can I show media in a Show element
kapa.ai
kapa.ai11mo ago
Let me check the knowledge base for you. One moment! :books: ---------------------- To display media in a Show element, you can use the appropriate field component for the media type. For example, if you're working with images, you can use the ImageField component. Unfortunately, the provided extracts do not contain specific examples of displaying media in a Show element. However, the general pattern would be to use the media URL stored in your data record and pass it to the appropriate field component. Here's a general example:
import { Show, ImageField } from "@refinedev/core"; // or "@refinedev/antd", "@refinedev/mui", etc.

const MyShowComponent: React.FC = () => {
const { queryResult } = useShow();
const { data, isLoading } = queryResult;
const record = data?.data;

return (
<Show isLoading={isLoading}>
{/* other fields */}
<ImageField source={record?.imageUrl} />
{/* other fields */}
</Show>
);
};
import { Show, ImageField } from "@refinedev/core"; // or "@refinedev/antd", "@refinedev/mui", etc.

const MyShowComponent: React.FC = () => {
const { queryResult } = useShow();
const { data, isLoading } = queryResult;
const record = data?.data;

return (
<Show isLoading={isLoading}>
{/* other fields */}
<ImageField source={record?.imageUrl} />
{/* other fields */}
</Show>
);
};
In this example, record?.imageUrl is the URL of the image you want to display. Replace imageUrl with the actual property name in your data record that holds the image URL. For more information on how to use the Show component and its related field components, refer to the Refine documentation (https://refine.dev/docs). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai can I have a delete edit and show button on a list?
kapa.ai
kapa.ai11mo ago
Let me check the knowledge base for you. One moment! :books: ---------------------- Yes, you can have Delete, Edit, and Show buttons on a list in Refine. You can use the DeleteButton and EditButton components provided by Refine. Here's an example of how you can add these buttons to a list:
import { DeleteButton, EditButton } from "@refinedev/mantine"; // or "@refinedev/antd", "@refinedev/mui", etc.
import { Group } from "@mantine/core"; // or equivalent from other UI libraries

// ...

const columns = React.useMemo<ColumnDef<any>[]>(
() => [
// ...
{
id: "actions",
accessorKey: "id",
header: "Actions",
cell: ({ getValue }) => {
return (
<Group noWrap>
<EditButton
hideText
size="xs"
recordItemId={getValue() as number}
variant="subtle"
/>
<DeleteButton
hideText
size="xs"
recordItemId={getValue() as number}
variant="subtle"
/>
</Group>
);
},
},
],
[]
);
import { DeleteButton, EditButton } from "@refinedev/mantine"; // or "@refinedev/antd", "@refinedev/mui", etc.
import { Group } from "@mantine/core"; // or equivalent from other UI libraries

// ...

const columns = React.useMemo<ColumnDef<any>[]>(
() => [
// ...
{
id: "actions",
accessorKey: "id",
header: "Actions",
cell: ({ getValue }) => {
return (
<Group noWrap>
<EditButton
hideText
size="xs"
recordItemId={getValue() as number}
variant="subtle"
/>
<DeleteButton
hideText
size="xs"
recordItemId={getValue() as number}
variant="subtle"
/>
</Group>
);
},
},
],
[]
);
In this example, the DeleteButton and EditButton are added to each row in the table under the Actions column. When clicked, the DeleteButton will delete the corresponding record, and the EditButton will redirect the user to the record edit page. For more information, refer to the Refine documentation (https://refine.dev/docs) and the blog post on building a React admin panel (https://refine.dev/blog/react-admin-panel). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai how to add these columns to List comontonent in mui
kapa.ai
kapa.ai11mo ago
Let me check the knowledge base for you. One moment! :books: ---------------------- To add these columns to a List component in Material UI, you can use the DataGrid component from @refinedev/mui. Here's an example:
import React from "react";
import {
useDataGrid,
DataGrid,
GridColumns,
EditButton,
DeleteButton,
List,
Stack,
} from "@refinedev/mui";

export const PostList: React.FC = () => {
const { dataGridProps } = useDataGrid<IPost>({
meta: {
populate: ["category"],
},
});

const columns = React.useMemo<GridColumns<IPost>>(
() => [
// ... other columns
{
headerName: "Actions",
headerAlign: "center",
field: "actions",
minWidth: 180,
align: "center",
flex: 1,
sortable: false,
renderCell: function render({ row }) {
return (
<Stack direction="row" spacing={1}>
<EditButton
size="small"
hideText
recordItemId={row.id}
/>
<DeleteButton
size="small"
hideText
recordItemId={row.id}
/>
</Stack>
);
},
},
],
[],
);

return (
<List>
<DataGrid {...dataGridProps} columns={columns} autoHeight />
</List>
);
};
import React from "react";
import {
useDataGrid,
DataGrid,
GridColumns,
EditButton,
DeleteButton,
List,
Stack,
} from "@refinedev/mui";

export const PostList: React.FC = () => {
const { dataGridProps } = useDataGrid<IPost>({
meta: {
populate: ["category"],
},
});

const columns = React.useMemo<GridColumns<IPost>>(
() => [
// ... other columns
{
headerName: "Actions",
headerAlign: "center",
field: "actions",
minWidth: 180,
align: "center",
flex: 1,
sortable: false,
renderCell: function render({ row }) {
return (
<Stack direction="row" spacing={1}>
<EditButton
size="small"
hideText
recordItemId={row.id}
/>
<DeleteButton
size="small"
hideText
recordItemId={row.id}
/>
</Stack>
);
},
},
],
[],
);

return (
<List>
<DataGrid {...dataGridProps} columns={columns} autoHeight />
</List>
);
};
In this example, the EditButton and DeleteButton are added to each row in the DataGrid under the Actions column. When clicked, the DeleteButton will delete the corresponding record, and the EditButton will redirect the user to the record edit page.

@kapa.ai does refine support tabbed navigation on show pages?
kapa.ai
kapa.ai11mo ago
Let me check the knowledge base for you. One moment! :books: ---------------------- Yes, Refine does support tabbed navigation on show pages. However, the specific implementation would depend on the UI library you're using with Refine (like Ant Design, Material UI, etc.). Unfortunately, the provided extracts do not contain specific examples of implementing tabbed navigation on show pages. But generally, you would use the tab components provided by your UI library and place your Show components or fields inside these tabs. For more information on how to use the Show component and implement tabbed navigation, refer to the Refine documentation (https://refine.dev/docs). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
