Hi @tuanna_. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Yes, you can call the getOne method from the data provider directly in a function. The getOne method is part of the data provider's methods and is expected to return a promise, meaning that it is async and can be used in a function. Here's an example of how you might use the getOne method in a function:
const dataProvider = {
// ...
getOne: async ({ resource, id, meta }) => {
// You can handle the request according to your API requirements.
return {
data,
};
},
// ...
};

const fetchRecord = async () => {
const { data } = await dataProvider.getOne({ resource: 'posts', id: 1 });
console.log(data);
};

fetchRecord();
const dataProvider = {
// ...
getOne: async ({ resource, id, meta }) => {
// You can handle the request according to your API requirements.
return {
data,
};
},
// ...
};

const fetchRecord = async () => {
const { data } = await dataProvider.getOne({ resource: 'posts', id: 1 });
console.log(data);
};

fetchRecord();
In this example, fetchRecord is a function that calls the getOne method from the data provider to fetch a single record. The resource and id parameters are passed to the getOne method to specify which record to fetch. Please note that this is a simplified example and you might need to adjust it based on your actual API requirements. For more information, you can refer to the Refine documentation (https://refine.dev/docs/api-reference/core/providers/data-provider/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

Let me check the knowledge base for you. One moment! :books: ---------------------- The error messages you're seeing are due to two issues: 1. The await keyword is used outside of an async function. The await keyword can only be used within an async function. You should mark your handleScanSuccess function as async:
const handleScanSuccess = async (result: string) => {
const { data } = await dataProvider.getOne({
resource: "products",
id: result,
});
console.log(data);
};
const handleScanSuccess = async (result: string) => {
const { data } = await dataProvider.getOne({
resource: "products",
id: result,
});
console.log(data);
};
2. The getOne method is not recognized on the dataProvider object. This could be due to how your dataProvider is defined or imported. Make sure that your dataProvider is correctly defined with a getOne method, and that it's correctly imported where you're trying to use it. Here's an example of how a dataProvider might be defined:
export const dataProvider = (apiUrl: string): DataProvider => ({
// ...
getOne: async ({ resource, id }) => {
const url = `${apiUrl}/${resource}/${id}`;
const { data } = await axiosInstance.get(url);
return {
data,
};
},
// ...
});
export const dataProvider = (apiUrl: string): DataProvider => ({
// ...
getOne: async ({ resource, id }) => {
const url = `${apiUrl}/${resource}/${id}`;
const { data } = await axiosInstance.get(url);
return {
data,
};
},
// ...
});
In this example, dataProvider is a function that returns an object with a getOne method. This getOne method is an async function that fetches a single record from the API. For more information, you can refer to the Refine documentation (https://refine.dev/docs/api-reference/core/providers/data-provider/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
