Mass class deletion

You cannot delete classes in a mass way from the web interface. This functionality is available only in the Administration tool.

Click on Mass class deletion in the Administration tool and following form will be displayed to you.

Select model first and then check off classes that you want to delete.
Button Delete classes starts the deletion.

There are couple of restrictions regarding deletion:

• classes set for deletion cannot be referenced by another ObjectGears object
• you cannot delete a class that has child classes that are not subject of deletion

The deletion is performed in couple of steps that are not performed within a single transaction. There are columns deleted in the first step which refer to the deleted classes. After that the classes themselves are deleted.
If the deletion process is interrupted due to the above stated reasons, remove these causes and repeat the deletion.
