    CREATE OPERATION HANDLING IS CONCERNED ONLY ABOUT ROOT models
    NON ROOT MODEL ITEMS ARE IGNORED

    We don't dump non-root models, since they belong to one root model
    any way and there data will be saved as part of a root model.
    example, if user created a task (non root model) and assigned it to contact
    cached data will look like
    {'changes': {'updated': IdentitySet([<crm.contact.models.Contact object at 0x7f5748a1f5c0>]),
    'deleted': IdentitySet([]),
    'created': IdentitySet([<crm.task.models.Task object at 0x7f574929dba8>])}}
    so Contact object has been updated any way and we'll handle that update add the task in contact data
    in File system.
