Bulk insert not validating document schema

[StoneMoe]

class Post:
    author = ListField(CustomDictField())

Post.objects.insert([Post(author={"a": 1})])

This will insert a dict value to author field in document

Any update on this? Using ClassName.objects.insert() does not validate 'required' fields as well. How to fix that?

I do data validating and type casting by myself, since validation feature in mongoengine is not consistent.
