Hi! A couple of questions. 1. I've got a "Product" class and a "Tag" class, related as m2m. If I delete a product, all rows referencing that product will be removed from the secondary table - which is good. However, the same will happen if I delete a tag (all references to the tag will be removed from the secondary table) - despite the fact that the tag is actually used in many products. Not good. How can I ensure that a tag can not be removed if it is referenced by any product?
2. I can do MyClass.iterate_properties()and check if a property is m2m relationship. But how can I find out which class it references?
