Two small concerns for ActiveRecord that can guard against direct creates, updates and destroys. Handy if you want to force the use of directing all persistence through service objects and guard against accidental CRUD operations in the console.

Include the gem in your Gemfile:

gem "model_guard"

Protects against #save, #save!, #update, #update!. Instead use #guarded_save, #guarded_save!, #guarded_update, #guarded_update! or #guarded_create.

class User < ActiveRecord::Base
  include ModelGuard::CreateOrUpdateGuard
end

CreateGuardedUser.guarded_create(name: "Joe")
user.guarded_update(name: "Joe")

or

user.allow_direct_create_or_update!
user.save

class User < ActiveRecord::Base
  include ModelGuard::DestroyGuard
end

Will raise an exception when calling destroy on an instance of User. Instead use guarded_destroy or guarded_destroy!.

user.guarded_destroy
user.guarded_destroy!
