Hi @VR. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To pass extra variables to the useOne hook in a GraphQL query, you can use the meta property. The meta property allows you to pass additional information, such as GraphQL queries and variables, to the data provider methods. Here is an example of how to pass extra variables to the useOne hook using a GraphQL query:

import gql from "graphql-tag";
import { useOne } from "@refinedev/core";

const GET_PRODUCT_QUERY = gql`
  query GetProduct($id: ID!, $extraVariable: String!) {
    product(id: $id, extraVariable: $extraVariable) {
      id
      title
      category {
        title
      }
    }
  }
`;

useOne({
  resource: "products",
  id: 1,
  meta: {
    gqlQuery: GET_PRODUCT_QUERY,
    gqlVariables: {
      extraVariable: "someValue",
    },
  },
});

import gql from "graphql-tag";
import { useOne } from "@refinedev/core";

const GET_PRODUCT_QUERY = gql`
  query GetProduct($id: ID!, $extraVariable: String!) {
    product(id: $id, extraVariable: $extraVariable) {
      id
      title
      category {
        title
      }
    }
  }
`;

useOne({
  resource: "products",
  id: 1,
  meta: {
    gqlQuery: GET_PRODUCT_QUERY,
    gqlVariables: {
      extraVariable: "someValue",
    },
  },
});

In this example: - GET_PRODUCT_QUERY is a GraphQL query that accepts an id and an extraVariable. - The useOne hook is called with the resource set to "products" and id set to 1. - The meta property includes the gqlQuery and gqlVariables fields. The gqlQuery field contains the GraphQL query, and the gqlVariables field contains the extra variables to be passed to the query. For more information, you can refer to the GraphQL section of the Data Fetching documentation (https://refine.dev/docs/guides-concepts/data-fetching/#graphql) and the Handling Filters with Custom GraphQL Variables (https://refine.dev/docs/advanced-tutorials/data-provider/handling-filters/#handle-custom-graphql-variables) documentation. If you need to pass additional headers or other meta information, you can also use the meta property as shown in the Simple REST documentation (https://refine.dev/docs/data/packages/simple-rest/#passing-custom-headers). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
