Answer 1

You want to find singular ServiceRequest . So, instead of where , use find :

sr = ServiceRequest.only_deleted.find(57)

or find_by if you don't want it to raise an error if the record isn't found:

sr = ServiceRequest.only_deleted.find_by(id: 57)

then you can call destroy on it:

sr.destroy

But it seems you need to actually destroy object from DB, since it's already marked as "destroyed", so you should rather use:

sr.really_destroy!
