Hi,
on our Terraform provider we have a lot of resources without id (not required for terraform but required on pulumi side :sweat_smile:).
I have the habit to add a computeID line in order to generate the ID based on an existing field.

Example:

`"ovh_domain_zone_dnssec": {`
                `Tok:       ovhResource(domainMod, "ZoneDNSSec"),`
                `ComputeID: delegateID("zone_name"),`
            `},`

BUT for one of our new resource I have a problem. I need to compute an ID based on the mix of TWO fields:

`delegateID("zone_name")`
`+`
`delegateID("sub_domain")`

How is it possible to do so?

Thank you

It is possible. `ComputeID` (of type <https://github.com/pulumi/pulumi-terraform-bridge/blob/ada8f50559b7f74e51d85a4bf4ec833e6aea9f24/pkg/tfbridge/info/info.go#L432|ComputeID>) is a function from state to a `resource.ID`. You can always write your own.

Cloudflare’s `cloudflare_leaked_credential_check` resource provides an example: <https://github.com/pulumi/pulumi-cloudflare/blob/6738a5d92ca2cee27e697f50ededb5cfd9218a69/provider/resources.go#L104-L108>.
