I'm trying to make a permission variable that is using a many-to-many relationship.
Something like this:
'{"company-ids":"companies.companyId"}'

When the user has many companies, it looks like this in the token, and I can use the _in operator in the permission rule to check
"x-hasura-company-ids": "{\"33333333-3333-3333-3333-333333333333\",\"33333333-3333-3333-3333-333333333333\"}"

However, if the user only has one company it looks like this, and the check breaks
"x-hasura-company-ids": "33333333-3333-3333-3333-333333333333"

And I get this error:
malformed array literal: \"33332a37-f01c-4195-9360-268136725b06\"

I understand that moving the single element out of an array is probably useful more often than not 😄 but is there a smart way to work around this?

I did try to wrap them in an or, doing both _eq and _in but that just makes both scenarios fail

could you try companies.companyId[]?

that worked!! thanks!

what is this syntax called?

jsonata - but the way we are using it is similar to jmespath, which I find nicer and is way more popular
https://jsonata.org/
https://jmespath.org/

awesome, thanks! will have a look at those, would all the functionality be available?

unfortunately not, only the . and [] operators. If interested in extending it a bit further don't hesitate to drop a feature request on GitHub or reach out to me through DM

Ok, makes sense. [] solved my case for now, but will do if something comes up!

Nice. I didn't know about this, we should document it.
