Soft delete extension for SilverStripe
Add a soft delete behaviour to your dataobjects. Objects are simply marked as deleted and kept in the database.
Soft delete will follow the same permissions patterns as delete.
ModelAdmin and SecurityAdmin are extended to add a new GridField action that replace the default delete action
This module depends on lekoala/silverstripe-cms-actions for displaying delete buttons
Simply replace your calls from delete to softDelete.
New extensions hooks are provided to avoid side effects (onBeforeSoftDelete, onAfterSoftDelete). These are ideals if you have child records that need to be soft deleted with their parent.
SilverStripe\Admin\ModelAdmin: softdelete_from_list: true softdelete_from_list_exclude:  extensions: - SoftDeleteModelAdmin SilverStripe\Admin\SecurityAdmin: softdelete_from_list: true softdelete_from_list_exclude:  extensions: - SoftDeleteSecurityAdmin
You can configure:
- softdelete_from_list: show delete button on a line. Enabled by default.
- softdelete_from_list_exclude: hide the delete button for these classes even if enabled globally
By default, the module will prevent any delete from happening. To allow deletion, you must set
SoftDeletable:$prevent_delete = false
The only way from the CMS UI to delete a record is to go to a soft deleted record and click "Really delete" which will call "forceDelete" on the record.
You can disable filtering globally, using
SoftDeletable::$disable = true
Or at query level
Tested with 4.4+
