MongoEngine不会保存默认的False值

Question

I have defined a User model and added a featured field to it:

class User(Document):
    email = EmailField(required=True)
    featured = BooleanField(default=False, required=True)

Then I create a user from this model and save it:

user = User(email=email, featured=False)
user.save()

But even having a default value and required flag I don't see that field created in the db if the BooleanField is set to False. When I set it to True in model or when create the user, it creates it and saves proper True value to it. I want this field to be always present on creation if it's False or True. What am I doing wrong?

What version are you running? We have a passing test case for this very issue:
