Hey presto, it's there!
If you want a method to be called on destroy, simply provide a _before\_destroy_ callback:
class Client < ActiveRecord::Base
acts_as_paranoid
```ruby
class Client < ActiveRecord::Base
acts_as_paranoid
before_destroy :some_method
before_destroy :some_method
def some_method
# do stuff
end
def some_method
# do stuff
end
...
end
...
end
```
You can replace the older acts_as_paranoid methods as follows:
find_with_deleted(:all) # => unscoped
find_with_deleted(:first) # => unscoped.first
find_with_deleted(id) # => unscoped.find(id)
```ruby
find_with_deleted(:all) # => unscoped
find_with_deleted(:first) # => unscoped.first
find_with_deleted(id) # => unscoped.find(id)
find_only_deleted(:all) # => only_deleted
find_only_deleted(:first) # => only_deleted.first
find_only_deleted(id) # => only_deleted.find(id)
find_only_deleted(:all) # => only_deleted
find_only_deleted(:first) # => only_deleted.first
find_only_deleted(id) # => only_deleted.find(id)
```
