Hello,
When I'm deleting model instance I want to check some conditions and if that conditions are true then allow deleting and if conditions are false don't allow user to delete entry.
So what  I thought, __del__() method is destructor and first I was thinking to use this function but after some testings it doesn't work as I want, so I must find another way. I want to find a way to test conditions before deletion happens and decide allow or not.
If question is still unclear tell me.
