Cascade deletion in Django models with GenericForeignKey

I have the following problem with Django.

class UserProfile(Model):
    inventory = models.M2M(InventoryItem)

class InventoryItem(Model):
    item = GenericForeignKey()

class Equipment(Model):
    base = GenericForeignKey()

Every user can have many items. Inventory item can point to equipment, materials and so on, but in this case it points to Equipment model. Equipment model has a relation to either Weapon or Armour or Accessory.

I need to remove a specific item from user's inventory.

UserProfile.objects.get(pk=1).inventory.objects.all()[0].delete()

** This also deletes equipment and weapon/armour/accessory objects related which is not intended. **

I have already added on_delete=DO_NOTHING on all foreign keys, but I do not see such option possible on GenericForeignKeys. What's the solution?

UserProfile.objects.get(pk=1).delete()

it looks like you're deleting the UserProfile, but not the specific item
