How to query custom type and filter by relationship with @prismicio/react

[leslie (Leslie Toledano)]

Hello there!
Im trying to create a slice that display a filter grid, in which my custom type (book) need to be filtered by Author (Custom Type) and by Category (Custom type).

I set up my books so they can have a relationship with author and category.
so its set up as follows: "A book can have one or multiple authors and one or multiple categories".

Since im developing everything inside a slice (in order to be accessible throughout the site), im using @prismic/react usePrismicDocumentsByType(documentType, params).

and in that way I can get all results and filter them out with javascript, but I was wondering if there's a way that I can fetch with that same hook pre-filtered data, I mean get them by type and author in one call.

Thank u!

Hello Leslie,

Welcome to the Prism ic community, and thanks for reaching out to us.

I believe what you want to achieve we have already discussed in the following threads:

Inverse relations - Reverse relationships queries

Hey Tommy, Thanks for posting this question! Yes, it is possible to query by relationship, both ways. I understand that in this example you have: products posts, which link to products Querying all of the products for each post is relatively straightforward. When you query a post, you will get all of the product links, which include the metadata about each product. If you use fetchLinks, GraphQuery, or GraphQL, you can fetch the products. (Let me know if you'd like more info about how to do…

Here are some documents in React.js and technical reference:

1. Pull in data from another document
2. Rest API technical reference.
3. GraphQuery API option.

Let me know if you have any further questions.

Thanks,
Priyanka
