Supabase functions
I need to use a supabase function to fetch a result of location decoding from long encoded postgis location string string to x and y values and distance calculation, i've implemented the function fetch_parking_spaces_by_distance(lat float, long float) that returns my desired table. I don't know how to implement it to display it in a list. Is there a way to override the schema and datasource for a supabase.rpc()?

Hi @Fifinio. 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. The information extracts provided do not contain specific details on how to use a Supabase function to fetch a result of location decoding from a long encoded PostGIS location string to x and y values and distance calculation. They also do not provide information on how to implement it to display it in a list or how to override the schema and datasource for a
supabase.rpc()
.
However, Refine does allow you to use a custom schema by passing the schema
property in the meta
object. Here's an example:
Source (https://refine.dev/docs/data/packages/supabase#schema---using-custom-schema)
For more detailed information, I recommend checking the official Refine (https://refine.dev/docs) and Supabase (https://supabase.io/docs) documentation.

How can I modify existing supabase data-provider to support supabase.rpc()?
@kapa.ai How can I modify existing supabase data-provider to support supabase.rpc()?
Let me check the knowledge base for you. One moment! :books:
----------------------
To modify the existing Supabase data provider to support
supabase.rpc()
, you would need to extend the existing data provider and add a new method that uses supabase.rpc()
.
Here's an example of how you might do this:
In this example, we're spreading the existing data provider methods and adding a new rpc
method. This rpc
method takes a resource
and params
as arguments, which correspond to the function name and parameters in your Supabase database. It then calls supabaseClient.rpc()
with these arguments and returns the data.
Please note that this is a general example and might need adjustments based on your specific use case.
For more information on how to use the data provider in Refine, you can check the official documentation (https://refine.dev/docs/api-reference/core/providers/data-provider/).

@kapa.ai can you show usage?
Let me check the knowledge base for you. One moment! :books:
----------------------
Sure, once you have your custom data provider set up with the
rpc
method, you can use it in your components like this:
In this example, useDataProvider
hook is used to access the dataProvider
inside a component. Then, the rpc
method is called with the name of the function (fetch_parking_spaces_by_distance
) and the parameters ({ lat: 40.7128, long: 74.0060 }
). The result is logged to the console.
Please note that this is a general example and might need adjustments based on your specific use case.

can i integrate it with useTable?
@kapa.ai can i integrate it with useTable?
Let me check the knowledge base for you. One moment! :books:
----------------------
Yes, you can integrate it with
useTable
. However, you would need to create a custom hook that uses useTable
and your custom rpc
method from the data provider. Here's an example of how you might do this:
In this example, useTableWithRpc
is a custom hook that takes a resource
and initialParams
as arguments. It uses useDataProvider
to get the data provider and useTable
to get the table props. Then, it calls dataProvider.rpc
with the resource
and initialParams
and updates the table props with the returned data.
You can use this custom hook in your components like this:
Please note that this is a general example and might need adjustments based on your specific use case.
For more information on how to use the data provider and useTable
in Refine, you can check the official documentation (https://refine.dev/docs/api-reference/core/providers/data-provider/).
