How reproducible:

Steps to Reproduce:

2. Associate this subnet with a hostgroup

Error

ERROR: update or delete on table "subnets" violates foreign key constraint "hostgroups_subnet_id_fk" on table "hostgroups" DETAIL: Key (id)=(2) is still referenced from table "hostgroups".
If you feel this is an error with Foreman itself, please open a new issue with Foreman ticketing system, You would probably need to attach the Full trace and relevant log entries.

Expected results:
A handled exception and perhaps a UI block on trying to delete a subnet that is already associated.

  • Category set to Rails

Missing an EnsureNotUsedBy.new(:hostgroups) on the subnet. Worth double checking all other foreign keys have similar before_destroy hooks for friendly errors.

I suggest to have Ori review other places foreign keys are missing before_destroy EnsureNotUsedBy.new
