I have Hasura-Graphql on top of Postgres which I used in Refine Graphql data provider. I have a table which has email as primary key instead of id. When I'm trying to use useOne, it requires id field which internally makes a query with id instead of email. How can I use useOne with tables having non-ID primary key?

---------------------- You can customize the idType in your Hasura data provider to handle tables with non-ID primary keys. In your case, you can create a mapping for the email primary key. Here's an example of how to do this:
const idTypeMap: Record<string, "Int" | "uuid" | "email"> = {
users: "Int",
posts: "uuid",
tableNameWithEmailPrimaryKey: "email",
};

const myDataProvider = dataProvider(client, {
idType: (resource) => idTypeMap[resource] ?? "uuid",
});
const idTypeMap: Record<string, "Int" | "uuid" | "email"> = {
users: "Int",
posts: "uuid",
tableNameWithEmailPrimaryKey: "email",
};

const myDataProvider = dataProvider(client, {
idType: (resource) => idTypeMap[resource] ?? "uuid",
});
Replace tableNameWithEmailPrimaryKey with the actual name of the table that has the email primary key. However, the useOne hook still expects an id parameter. To handle this, you can modify your data provider's getOne method to use the custom primary key based on the resource name. Unfortunately, the provided extracts do not contain enough information to show you how to modify the getOne method specifically for this case. For more information on Hasura data provider and useOne, you can refer to the following sources: - Hasura Data Provider (https://refine.dev/docs/examples/data-provider/hasura) - useOne Hook (https://refine.dev/docs/api-reference/core/hooks/data/useOne) ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

you can sent any variables with metaData
const { queryResult } = useShow({
metaData: {
variables: {
email: "email.com"
}
}
});
const { queryResult } = useShow({
metaData: {
variables: {
email: "email.com"
}
}
});
