# AfterSave Behavior
|

-A CakePHP behavior to allow the entity to be available inside afterSave() callback.
|
|
|
+A CakePHP behavior to allow the entity to be available inside afterSave() callback in the state
|
|
|
+it was before the save.
|
|
|
|
|
|
## Introduction
|
|
|
It takes a clone of the entity from beforeSave(). This allows all the
|
|
|
info on it to be available in the afterSave() callback or from the outside without resetting (dirty, ...).
|
|
|
|
|
|
+This can be useful if one wants to compare what fields got changed, or e.g. for logging the diff.
|
|
|
+
|
|
|
### Technical limitation
|
|
|
Make sure you do not further modify the entity in the table's beforeSave() then. As this would
|
|
|
not be part of the cloned and stored entity here.
