Access non-resource data via supabase

I'm trying to query my "user_types" table to see the current type of my user, but useCustom requires not a function but an api url, which I am not using since I am using supabase.

Hi @Ab. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- It seems like you're trying to access non-resource data using Supabase with useCustom, but useCustom requires an API URL, which is not applicable in your case since you're using Supabase. From the provided knowledge sources, it appears that the custom method is not implemented in the refine-supabase data provider. This is confirmed in the following extract:

Source: Blog > Setting Up the Client App > Exploring the App > <Refine />'s dataProvider Prop Part 4 (https://refine.dev/blog/refine-pixels-2#refine-s-dataprovider-prop)
custom: () => {  
throw Error("Not implemented on refine-supabase data provider.");  
},
custom: () => {  
throw Error("Not implemented on refine-supabase data provider.");  
},

Given this limitation, you won't be able to use useCustom directly with Supabase in refine. Instead, you might need to use Supabase's client directly to perform your custom queries. Here is an example of how you can query the user_types table using the Supabase client directly:

import { supabaseClient } from 'path-to-your-supabase-client';

const fetchUserTypes = async () => {
    const { data, error } = await supabaseClient
        .from('user_types')
        .select('*');

    if (error) {
        console.error('Error fetching user types:', error);
        return;
    }

    console.log('User types:', data);
};

fetchUserTypes();

import { supabaseClient } from 'path-to-your-supabase-client';

const fetchUserTypes = async () => {
    const { data, error } = await supabaseClient
        .from('user_types')
        .select('*');

    if (error) {
        console.error('Error fetching user types:', error);
        return;
    }

    console.log('User types:', data);
};

fetchUserTypes();

This approach bypasses the useCustom hook and directly uses the Supabase client to fetch data from the user_types table. For more information on how to use Supabase with refine, you can refer to the Supabase documentation in refine (https://refine.dev/docs/data/packages/supabase#adding-an-edit-page).

@kapa.ai Should I use react-query to handle this?

kapa.ai•3mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- Yes, you can use React Query to handle this by integrating it with the Supabase client. React Query is a powerful tool for managing server state, including fetching, caching, and synchronizing data. Here’s how you can use React Query with Supabase to query your user_types table: 1. Install React Query: If you haven't already, you need to install React Query. You can do this using npm or yarn:

    npm install react-query
    # or
    yarn add react-query

    npm install react-query
    # or
    yarn add react-query

2. Set up a Query Client: You need to set up a Query Client and wrap your application with the QueryClientProvider.

    import React from 'react';
    import { QueryClient, QueryClientProvider } from 'react-query';
    import App from './App';

    const queryClient = new QueryClient();

    const Root = () => (
        <QueryClientProvider client={queryClient}>
            <App />
        </QueryClientProvider>
    );

    export default Root;

    import React from 'react';
    import { QueryClient, QueryClientProvider } from 'react-query';
    import App from './App';

    const queryClient = new QueryClient();

    const Root = () => (
        <QueryClientProvider client={queryClient}>
            <App />
        </QueryClientProvider>
    );

    export default Root;

3. Create a Query Function: Define a function to fetch data from Supabase.

    import { supabaseClient } from 'path-to-your-supabase-client';

    const fetchUserTypes = async () => {
        const { data, error } = await supabaseClient
            .from('user_types')
            .select('*');

        if (error) {
            throw new Error(error.message);
        }

        return data;
    };

    import { supabaseClient } from 'path-to-your-supabase-client';

    const fetchUserTypes = async () => {
        const { data, error } = await supabaseClient
            .from('user_types')
            .select('*');

        if (error) {
            throw new Error(error.message);
        }

        return data;
    };

4. Use React Query to Fetch Data: Use the useQuery hook to fetch data in your component.

    import React from 'react';
    import { useQuery } from 'react-query';

    const UserTypes = () => {
        const { data, error, isLoading } = useQuery('userTypes', fetchUserTypes);

        if (isLoading) return <div>Loading...</div>;
        if (error) return <div>Error: {error.message}</div>;
return (
            <ul>
                {data.map((type) => (
                    <li key={type.id}>{type.name}</li>
                ))}
            </ul>
        );
    };

    export default UserTypes;

    import React from 'react';
    import { useQuery } from 'react-query';

    const UserTypes = () => {
        const { data, error, isLoading } = useQuery('userTypes', fetchUserTypes);

        if (isLoading) return <div>Loading...</div>;
        if (error) return <div>Error: {error.message}</div>;
return (
            <ul>
                {data.map((type) => (
                    <li key={type.id}>{type.name}</li>
                ))}
            </ul>
        );
    };

    export default UserTypes;

By using React Query, you can leverage its powerful features like caching, background updates, and error handling, which can significantly improve the performance and user experience of your application. For more detailed information on using React Query, you can refer to the Beginner's Guide to React Query (https://refine.dev/blog/react-query-guide#introduction).
