Hi @Sly. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To extract a specific value from another resource using the useOne hook in refine, you need to specify the resource and id parameters. The resource parameter is the name of the resource you want to fetch data from, and the id parameter is the identifier of the specific record you want to fetch. Here's an example of how you can use the useOne hook to fetch a specific item from the "itens" resource:
import { useOne } from "@refinedev/core";

const { data, isLoading, isError } = useOne({
resource: "itens",
id: "your_item_id", // replace with your item's id
});

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

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

const item = data?.data;

console.log(item?.name); // logs the name of the item
import { useOne } from "@refinedev/core";

const { data, isLoading, isError } = useOne({
resource: "itens",
id: "your_item_id", // replace with your item's id
});

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

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

const item = data?.data;

console.log(item?.name); // logs the name of the item
In this example, useOne fetches a single record from the "itens" resource with the specified id. The fetched data is then stored in the data variable. You can access the name property of the item using item?.name. Please replace "your_item_id" with the actual id of the item you want to fetch. For more information, you can refer to the useOne documentation (https://refine.dev/docs/data/hooks/use-one). Please note that the useOne hook triggers a new request when the resource or id properties change. So, if you want to fetch a different item, you can simply change the id parameter. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai can I use filters on useOne?
kapa.ai
kapa.ai2mo ago
Let me check the knowledge base for you. One moment! :books: ---------------------- No, the useOne hook does not support filters directly. The useOne hook is designed to fetch a single record by its unique identifier (ID). If you need to fetch a record based on a specific field other than the ID, you would typically use the useList or useCustom hooks with appropriate filters. For example, if you want to fetch a record from the "itens" resource based on a specific field like "name", you can use the useList hook with filters:
import { useList } from "@refinedev/core";

const { data, isLoading, isError } = useList({
resource: "itens",
filters: [
{
field: "name",
operator: "eq",
value: "desired_name", // replace with the desired name
},
],
});

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

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

const items = data?.data ?? [];
const item = items.length > 0 ? items[0] : null;

console.log(item); // logs the item with the desired name
import { useList } from "@refinedev/core";

const { data, isLoading, isError } = useList({
resource: "itens",
filters: [
{
field: "name",
operator: "eq",
value: "desired_name", // replace with the desired name
},
],
});

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

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

const items = data?.data ?? [];
const item = items.length > 0 ? items[0] : null;

console.log(item); // logs the item with the desired name
In this example, useList is used to fetch items from the "itens" resource where the "name" field matches the specified value. The filters property is used to specify the filtering criteria. For more information on filtering with useList, you can refer to the useList documentation (https://refine.dev/docs/data/hooks/use-list#filtering). If you need to perform more complex queries, you can use the useCustom hook to make custom requests to your API:
import { useCustom } from "@refinedev/core";

const { data, isLoading, isError } = useCustom({
url: "/itens",
method: "get",
config: {
params: {
name: "desired_name", // replace with the desired name
},
},
});

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

if (isError) {
return <div>Something went wrong!</div>;
}
const item = data?.data?.[0];

console.log(item); // logs the item with the desired name
import { useCustom } from "@refinedev/core";

const { data, isLoading, isError } = useCustom({
url: "/itens",
method: "get",
config: {
params: {
name: "desired_name", // replace with the desired name
},
},
});

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

if (isError) {
return <div>Something went wrong!</div>;
}
const item = data?.data?.[0];

console.log(item); // logs the item with the desired name
In this example, useCustom is used to make a custom GET request to the "itens" endpoint with a query parameter for the "name" field. For more information on using useCustom, you can refer to the useCustom documentation (https://refine.dev/docs/data/hooks/use-custom). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai I have a subtotal row. How to sum all numbers of this row
kapa.ai
kapa.ai4w ago
Let me check the knowledge base for you. One moment! :books: ---------------------- To sum all numbers in a subtotal row, you can use JavaScript's array methods to iterate over the items and calculate the sum. Assuming you have a list of items with a subtotal field, you can use the reduce method to sum up all the subtotals. Here's an example of how you can achieve this:
const items = [
{ id: 1, subtotal: 100 },
{ id: 2, subtotal: 200 },
{ id: 3, subtotal: 150 },
// Add more items as needed
];

const totalSubtotal = items.reduce((acc, item) => acc + item.subtotal, 0);

console.log(totalSubtotal); // logs the sum of all subtotals
const items = [
{ id: 1, subtotal: 100 },
{ id: 2, subtotal: 200 },
{ id: 3, subtotal: 150 },
// Add more items as needed
];

const totalSubtotal = items.reduce((acc, item) => acc + item.subtotal, 0);

console.log(totalSubtotal); // logs the sum of all subtotals
In this example, items is an array of objects where each object represents an item with a subtotal field. The reduce method is used to iterate over the array and accumulate the sum of all subtotal values. If you are working within a React component and fetching data from an API, you can integrate this logic after fetching the data. Here's an example using the useList hook from refine:
import React from "react";
import { useList } from "@refinedev/core";

const SubtotalSum = () => {
const { data, isLoading, isError } = useList({
resource: "itens",
});

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

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

const items = data?.data ?? [];
const totalSubtotal = items.reduce((acc, item) => acc + item.subtotal, 0);

return (
<div>
<h3>Total Subtotal: {totalSubtotal}</h3>
</div>
);
};

export default SubtotalSum;
import React from "react";
import { useList } from "@refinedev/core";

const SubtotalSum = () => {
const { data, isLoading, isError } = useList({
resource: "itens",
});

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

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

const items = data?.data ?? [];
const totalSubtotal = items.reduce((acc, item) => acc + item.subtotal, 0);

return (
<div>
<h3>Total Subtotal: {totalSubtotal}</h3>
</div>
);
};

export default SubtotalSum;
In this example, the useList hook is used to fetch items from the "itens" resource. After fetching the data, the reduce method is used to calculate the sum of all subtotal values, and the result is displayed in the component. For more information on using the useList hook, 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: ----------------------
