gem 'kakurenbo'

Usage

You need only to add 'deleted_at' to model.

rails generate migration AddDeletedAtToModels deleted_at:datetime

The model having deleted_at becomes able to soft-delete automatically.

Kakurenbo provides acts_as_paranoid method for compatibility.

Basic Example

soft-delete

# if action is cancelled by callbacks, return false.
model.destroy

# if action is cancelled by callbacks, raise ActiveRecord::RecordNotDestroyed.
model.destroy!

# selected model will be destroyed.
Model.where(:foo => 'bar').destroy_all

when want without callbacks.

model.delete

# selected model will be deleted.
Model.where(:foo => 'bar').delete_all

restore a record

# if action is cancelled by callbacks, return false.
model.restore

# if action is cancelled by callbacks, raise ActiveRecord::RecordNotRestored.
model.restore!

When restore, call restore callbacks.before_restore after_restore

hard-delete

Use hard option.

model.destroy(hard: true)

# without callbacks.
model.delete(hard: true)

# selected model will be destroyed.
Model.where(:foo => 'bar').destroy_all(nil, hard: true)

# selected model will be destroyed.
Model.where(:foo => 'bar').delete_all(nil, hard: true)

check if a record is fotdeleted

model.destroyed?
