Hi @Sly. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- You can normalize the data returned by the backend using the normalizeData function in the strapi-v4 data provider of Refine. Here is an example of how the data will look after normalization:

{  
 "id": 1,  
 "title": "My title",  
 "content": "Long content..."  
}

{  
 "id": 1,  
 "title": "My title",  
 "content": "Long content..."  
}

This function is used to customize the data returned by the backend. You can find more details about this in the Refine documentation (https://refine.dev/docs/data/packages/strapi-v4). Please note that the normalization process is handled internally by the data provider and you don't need to call this function manually. If you want to further customize the data, you might need to extend the data provider or handle the data transformation in your components or services. For more complex data structures, there was a discussion on GitHub about deep data normalization for the strapi-v4 data provider. You can find more details about this discussion here (https://github.com/refinedev/refine/issues/1485). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai How to fetch this data using useList?

kapa.ai•6mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- To fetch data from a resource, you can use the useList hook provided by Refine. Here is a basic example of how to use it:

import { useList, HttpError } from "@refinedev/core";  
  
interface IProduct {  
 id: number;  
 name: string;  
 material: string;  
}  
  
const ProductList: React.FC = () => {  
 const { data, isLoading, isError } = useList<IProduct, HttpError>({  
 resource: "products",  
 });  
  
 const products = data?.data ?? [];  
  
 if (isLoading) {  
 return <div>Loading...</div>;  
 }  
  
 if (isError) {  
 return <div>Something went wrong!</div>;  
 }  
  
 return (  
 <ul>  
 {products.map((product) => (  
 <li key={product.id}>  
 <h4>  
 {product.name} - ({product.material})  
 </h4>  
 </li>  
 ))}  
 </ul>  
 );  
};

import { useList, HttpError } from "@refinedev/core";  
  
interface IProduct {  
 id: number;  
 name: string;  
 material: string;  
}  
  
const ProductList: React.FC = () => {  
 const { data, isLoading, isError } = useList<IProduct, HttpError>({  
 resource: "products",  
 });  
  
 const products = data?.data ?? [];  
  
 if (isLoading) {  
 return <div>Loading...</div>;  
 }  
  
 if (isError) {  
 return <div>Something went wrong!</div>;  
 }  
  
 return (  
 <ul>  
 {products.map((product) => (  
 <li key={product.id}>  
 <h4>  
 {product.name} - ({product.material})  
 </h4>  
 </li>  
 ))}  
 </ul>  
 );  
};

In this example, useList is used to fetch data from the "products" resource. The data is then mapped to a list of products. If the data is still loading, a loading message is displayed. If there is an error, an error message is displayed. You can replace "products" with the name of your resource. The IProduct interface should also be replaced with the structure of your data. For more information, you can refer to the useList documentation (https://refine.dev/docs/data/hooks/use-list). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai how to retrieve the data below to show only the id value 230? [ { "id": 230 } ]

kapa.ai•6mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- To retrieve a specific record by its id, you can use the useShow hook provided by Refine. However, the useShow hook requires the id to be passed as a parameter. Here's a basic example:

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

const ProductDetail: React.FC = () => {
  const { data, isLoading, isError } = useShow({
    resource: "products",
    id: "230", // replace with the id of the record
  });

  if (isLoading) {
    return <div>Loading...</div>;
  }

  if (isError) {
    return <div>Something went wrong!</div>;
  }

  return <div>{data?.data.id}</div>;
};

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

const ProductDetail: React.FC = () => {
  const { data, isLoading, isError } = useShow({
    resource: "products",
    id: "230", // replace with the id of the record
  });

  if (isLoading) {
    return <div>Loading...</div>;
  }

  if (isError) {
    return <div>Something went wrong!</div>;
  }

  return <div>{data?.data.id}</div>;
};

In this example, useShow is used to fetch a single record from the "products" resource with the id of "230". The id of the record is then displayed. If the data is still loading, a loading message is displayed. If there is an error, an error message is displayed. You can replace "products" with the name of your resource and "230" with the id of your record. For more information, you can refer to the useShow documentation (https://refine.dev/docs/data/hooks/use-show#showid). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
