Converts a value to a tenant. To add this to a resource, implement the protocol like so:application

What this should do is entirely dependent on how you've set up your tenants. This example assumes that you want the tenant to be org_#{organization_id}, but it could also be something like organization.schema.

defmodule MyApp.Organization do
  use Ash.Resource, ...

  ...

  defimpl Ash.ToTenant do
    def to_tenant(%{id: id}, _resource), do: "org_#{id}"
  end
end
