To insert many-to-many relationships in Supabase from Refine, you need to handle the intermediary table that represents the many-to-many relationship. Here’s a step-by-step guide on how to achieve this:
Step 1: Define Your Tables
Assume you have the following tables:
-
posts
table: id
, title
- categories
table: id
, name
- posts_categories
table: post_id
, category_id
(composite primary key)
Step 2: Create the Relationship in Supabase
Ensure that your posts_categories
table is set up correctly with a composite primary key. This is necessary for the select expression to work.
Step 3: Modify the Form Data Before Submitting
When creating a new post
and associating it with multiple categories
, you need to handle the form data appropriately. You can use the useCreate
or useCreateMany
hooks from Refine to insert data into the posts_categories
table.
Here’s an example of how you can modify the form data before submitting it:
Step 4: Handle Filtering by Categories
To filter posts by categories in a many-to-many relationship, you can use the metaData.select
option in the useTable
hook:
This setup ensures that the data retrieved includes the related categories.
