host can be nil here if an invalid id is passed; consider handling the not-found case (e.g., 404) to avoid a 500 from save_host.

Same issue as update: if host is nil, host.destroy will raise; consider returning a 404 or similar when the record isn’t found. (Related to the update action above.)

self.host.sub! will raise if host is nil; guarding for presence before normalizing (or defaulting to an empty string) will prevent validation-time exceptions.

The query uses lower(host) = ? but doesn’t lowercase the bound value; using host.downcase (or lower(?)) avoids case-mismatch issues for mixed-case hosts.
