User which has a has_one relationship with another resource called ImpersonatePermissions. When I create a new user, I want to also create a new in the impersonate_permissions table. To do that, I believe that I need to use manager_relationship.change manage_relationship call, but all the example I found uses an action input argument to set the args, and I don't want that since I don't want the caller to be able to change the arguments.
