BABYLISTMADE FOR TECH-SAVVY MOMS USED BY LITERALLY EVERYONE

THE RESULT

• No matter how much time you put into optimizing user experience, there will always be people who defy expectations.

• Accidents will happen.

• Accounts will be deleted.

• You must be your users’ source control.

DON’T WORRY. I GOT THIS.

THE WORKAROUND: IS_ACTIVE

• Create a database migration to add column is_active to tables prone to disaster. Which can be ANYTHING a user has the power to destroy - users, registries, items, reservations, etc.

• Command line: rails g migration add_is_active

YOUR MODELS: OVERRIDE DESTROY

• Now, your problem records live on FOREVER…just in case you need to switch them back to active.

• P.S. - Difference between the destroy method and the delete method. You could override the delete method, but then you don’t get callbacks like before_destroy.

DEFAULT SCOPE (HIDE THE INACTIVE STUFF BY DEFAULT)

• RegItem.all # SELECT * FROM reg_items WHERE is_active = true;

• Reference: http://apidock.com/rails/ActiveRecord/Base/default_scope/class

UNSCOPED (OK FIND THE INACTIVE STUFF SOMETIMES)

• Example: Item on registry was deleted by accident. User freaking out because it was this random onesie on Etsy they’ll never be able to find again. Customer support needs to run a query to find the name of the deleted item.

• Source: http://apidock.com/rails/ActiveRecord/Base/unscoped/class

BENEFITS TO THIS APPROACH• Key user information is never destroyed, so data restoration is 100%

possible. Happy users!

• Restoration is as simple as changing the is_active column to “true” - which means super easy integration for an admin panel. Happy customer support people!

• More data is saved about user behavior. (“On average, accidental deletes happen for 50% of our registry items. Something must be wrong with our user interface.”)

• Simple UI - Users never need to know what they’re doing behind the scenes. There’s no record on their end of inactive vs. active objects. They think they’re just deleting as normal and then assume you have magic powers. Yay!

FIN.
