Multiple categories for a post?

[ShawonAshraf]

Currently, if I add multiple categories for a post like this, let's say

---

title: test
author: testAuthor
category: ["t1", "t2"]
cover: someImage.png

I get a blank page and graphql query related error on the console. Any way around this?

This requires a lot of changes in tens of different files. I've been trying to do this for a couple of hours now and I'm currently stuck at an error that I'm unable to debug. Did you get any further with this?

Ok, looks like I got it now. Here is a commit in my fork: baobabKoodaa/blog@adeebb7

Are you sure just changing the graphql queries won't solve this? I was tinkering with the queries, yet to reach a conclusion!

[baobabKoodaa]

Yes I'm sure. In addition to changing the GraphQL queries you also need to change the JS where you mangle the result of the query. We used to just get a String, now we get an array of Strings, so we need to handle it differently.

If you still need multi category support check out my fork

But you need to provide category as an array for all posts
I couldn't get GraphQL to accept both string and array
