Right now a role can have a check and permissions associated with the check.

What I was wondering, is if it would be possible to have multiple sequential checks and permissions.

Let me describe a use case. I will try to simplify it for this particular Github issue.

products
---
id
name
price
components
resellers []
company_id

components
----
id
name
product_id

resellers
---
product_id
reseller_company_id

The idea is that companies (supplier) can create a product. And give that product as a component to another company (reseller). This other company (reseller) will get the product as a component and can use it, and other components, to build a new product.

So, when a company (reseller) views its own products, it will doing a query like this:

products { <-- lets view my products
  name
  price
  components { <-- lets see all my components for this products
    product {  <-- lets see what my supplier is naming this product
      name
    }
  }
}

Now, You might want to create a permissions for this. But it is very hard. Maybe impossible, with the current Hasura. My first try:

{
  _or: [{
    company_id: { _eq: x-hasura-company-id} <-- I want to be able to see my products

  }, {
    resellers {
      reseller_company_id: { _eq: x-hasura-company-id } <-- I also want to see some information about proucts of my components
    }
  }]
}

Then the permissions. Errrr. For the first check company_id: { _eq: x-hasura-company-id} I want to see everything.
For the seconds check resellers { reseller_company_id: { _eq: x-hasura-company-id }} I want to only be able to see some limited information (ex name).

Solution (discussion starter)

Lets say you would be able to make multiple sequential checks/permissions. Like this:

check/permission #1

{
  company_id: { _eq: x-hasura-company-id}
}

Allow to see everything

check/permission #2

{
  resellers {
    reseller_company_id: { _eq: x-hasura-company-id }
  }
}

Allow to see name only

This is the query I am making:

products { <-- I am an owner, Check #1 OK
  name
  price
  components {
    product {  <-- I am a reseller, Check #1 fails, Check #2 OK
      name
    }
  }
}

Would this be possible and suitable?

Thanks
