Select - Getting Label based on Foreign Key

Hi! I have a resource locationProducts, which maps a 'locationID' to a 'productID' from another resource called product. I'd like to introduce a <Select/> to choose a locationProduct. However, the label is currently productID. Is there a preferred way for me to reference the resource product for each productID in locationProducts to retrieve product's name to use as value?

Hi @avangeous. 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 use the useSelect hook provided by refine to handle this. The useSelect hook allows you to handle an Ant Design Select component and includes out-of-the-box features such as fetchSize, sorting, and filtering. Here is a basic example of how to use useSelect hook:
import { useSelect } from "@refinedev/core";

interface IProduct {
id: number;
title: string;
}

const LocationProductCreate: React.FC = () => {
const { options } = useSelect<IProduct>({
resource: "products",
});

return (
<label>
Select a product:
<select>
{options?.map((option) => (
<option key={option.value} value={option.value}>
{option.label}
</option>
))}
</select>
</label>
);
};
import { useSelect } from "@refinedev/core";

interface IProduct {
id: number;
title: string;
}

const LocationProductCreate: React.FC = () => {
const { options } = useSelect<IProduct>({
resource: "products",
});

return (
<label>
Select a product:
<select>
{options?.map((option) => (
<option key={option.value} value={option.value}>
{option.label}
</option>
))}
</select>
</label>
);
};
In this example, useSelect is used to fetch the list of products from the "products" resource. The options returned by useSelect is an array of objects, each representing a product. You can map over these options to render them as options in a select input. The label property of each option is used as the display text in the select input, and the value property is used as the value of the option. You can replace "products" with "locationProducts" and adjust the IProduct interface to match the structure of your locationProduct objects. For more information, you can refer to the useSelect documentation (https://refine.dev/docs/api-reference/core/hooks/useSelect/index). Please note that this example assumes that your dataProvider is set up to handle the "products" resource. If it's not, you'll need to adjust your dataProvider accordingly. You can refer to the creating a data provider (https://refine.dev/docs/tutorial/understanding-dataprovider/create-dataprovider/) section for an example of how resources are handled. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

Ended up using a useList and manually mapping. If there's a better way, though, I'm all ears

hello @avangeous, you can define field names in useSelect https://refine.dev/docs/api-reference/core/hooks/useSelect/#optionlabel-and-optionvalue
useSelect | refine
useSelect hook allows you to manage any select (like a Html `` tag, React Select, etc...) component. Since it is designed as headless, It expects you to handle the UI.
