[BUG] Playground won't accept rules inside an entity

[mezakos]

Describe the bug
In Playground I get an error: "expected token to be relation, permission, attribute, got rule instead" when I try to create a rule inside an entity.

To Reproduce
Create a rule inside an entity

entity user {
    attribute age integer

    rule check_age(age integer){
        age >= 18
    }

    permission buy_beer = check_age(age)
}

Expected behavior
Accept the schema as valid. In the Permify docs, in the healthcare example there is a rule inside an entity, so I'm assuming it should be valid.
https://docs.permify.co/getting-started/examples/healthcare

Environment (please complete the following information, because it helps us investigate better):

• Permify Playground

@mezakos is this replicable on the latest version of the Permify executable (1.6.2) or only in the playground?

[mezakos]

@mooreds yes it is replicable with that as well (I tried using docker)

We did some looking and I think this is an error in the documentation that we need to fix.

As a workaround, you can move the rule outside of the entity:

entity user {
    attribute age integer

    permission buy_beer = check_age(age)
}

rule check_age(age integer){
   age >= 18
}

I'm going to leave this open until the documentation is updated.

Thanks!

@mooreds Thank you! Just another question: I noticed that rule parameters has to be the same name as the attribute you run the rule against. Is this intentional or maybe a bug? Also I wanted to create a rule with no parameters (only to check context.data.somevar == 'SomeText') but I realized that this is invalid because rules has to have parameters and the parameter has to be an attribute. Is there any chance that this will change in the future?

We try to keep github issues for bug reports and feature requests.

Sure, sorry about that
