Call Supabase RPC functions with useTable hook

Hi there, Thanks in advance for reading. I've been struggling to find an answer to this. I have a Postgres function in Supabase that performs a very specific (and kinda complicated) query, with quite a lot of filters, conditions and even geolocation checks. It would be very very handy if I was able to call that RPC function within the useTable hook to get it integrated through the Supabase Data Provider, but I can't to find any examples or tips on how to do that. Searching here in the conversations I found that the suggested way is to not actually use the hook, but to call supabaseClient.rpc(...) directly. The thing is, would I have to code my own hook to get it working just as useTable does? Doesn't it ruin the advantages of using Refine at all? Is there a way to safely extend the Supabase Data Provider so I can add a method to call RPC functions, or wrap the existing methods? I have checked the Supabase Data Provider code and found out that it is hardcoded to use the select method, thus making it impossible (AFAIK) to call RPC functions. Since I rely heavily on using Postgres Functions for many operations across the app, this is quite important for my project. I am kinda new to Refine, so I might be missing something here. Any help is really appreciated.

Hi @❴𝖒𝖔𝖗❵. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Hmm, I don't know enough to give you a confident answer yet. However, based on the information provided, it seems that you might need to extend or override the getList method of the data provider to call your custom RPC function. In one of the Github discussions (https://github.com/refinedev/refine/issues/2802), a member suggested overriding the getList method of the data provider to customize the behavior. You might be able to apply a similar approach to call your RPC function. Here's a rough idea of how you might do it:
const myCustomGetList = async (resource, params) => {
// Call your RPC function here using supabaseClient.rpc(...)
// You might need to adjust the parameters and the return value to match the expected format
};

// Then, when setting up the data provider in your App component, you can override the getList method like this:
<Refine dataProvider={{...dataProvider, getList: myCustomGetList}} />
const myCustomGetList = async (resource, params) => {
// Call your RPC function here using supabaseClient.rpc(...)
// You might need to adjust the parameters and the return value to match the expected format
};

// Then, when setting up the data provider in your App component, you can override the getList method like this:
<Refine dataProvider={{...dataProvider, getList: myCustomGetList}} />
Please note that this is just a rough idea and might need adjustments based on your specific use case. For more detailed information, you might want to check out the Refine documentation (https://refine.dev/docs/data/data-provider/) and the Supabase documentation (https://supabase.com/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
