Hi @fuddlesworth. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

In refine, you can handle relational data using the
useMany
hook and filter <Table>
by categories with the help of useSelect
[^1^]. When using Supabase as your data provider, you can pass a select
value in the meta
object to perform relational database operations [^2^].
For example, if you have a posts -> categories
relationship and you want to get the title
data from the categories
table and display it on the List page, you can do something like this:
[^2^]
In this example, useList
, useOne
, useMany
hooks are using Supabase select
property internally. So you can pass parameters to the Supbase select method using meta
property [^2^].
Please note that the select
value in the meta
object is using Supabase select
property internally, which means you can use the same syntax as you would in a Supabase API call.
For more complex joins or queries, you might need to adjust the select
value accordingly. If you need more specific help, please provide more details about your data structure and the exact query you're trying to perform.

@kapa.ai what's an example of using count with select
Let me check the knowledge base for you. One moment! :books:
----------------------
In refine, when using Supabase as your data provider, you can use the
count
option with select
to get the exact count of rows in a table. This is useful for pagination purposes. Here's an example of how you can use it:
[^3^]
In this example, supabaseClient.from(resource).select()
is used to select data from a specific resource. The count: "exact"
option is passed to the select
method to get the exact count of rows.
Please note that this is a part of a larger data provider function and might need to be adjusted according to your specific use case.

@kapa.ai how do i use select to select Rooms joining on project_id and from Windows joining on room_id
Let me check the knowledge base for you. One moment! :books:
----------------------
In refine, when using Supabase as your data provider, you can use the
select
value in the meta
object to perform relational database operations. However, the provided extracts do not contain a specific example of joining Rooms
on project_id
and Windows
on room_id
.
Here's a general example of how you might structure your select
statement:
In this example, rooms
is the main resource, and we're joining on projects
and windows
. The (*)
after each resource indicates that we want to select all fields from those resources. You would replace projects
and windows
with the actual names of your resources.
Please note that this is a general example and might need to be adjusted according to your specific use case and data structure. For more complex joins or queries, you might need to adjust the select
value accordingly.
For more information, you can refer to the Supabase documentation (https://supabase.io/docs/reference/javascript/select) on how to structure select
statements for joins.
