SequenceField not saving

[macfire]

I have a model that requires an integer for the _id field, so I am using SequenceField to auto-increment.

When creating a new object from the model directly, the object will save and SequenceField auto-increments correct. But when saving from a schema, the SequenceField function is not called.

Not sure if this is a bug, or am I not implementing correctly?

class Book(me.Document):
    _id = me.SequenceField(primary_key=True, 
                           collection_name="counter", 
                           sequence_name="books")
    title = me.StringField()

class BookSchema(ModelSchema):
    class Meta:
        model = Book


""" Examples using Flask-Restful"""

parse = reqparse.RequestParser()
parse.add_argument('title')

# Saving model directly
class Book(Resource):
    def put(self):
        args = parse.parse_args()
        book = Book(title=arg['title'])
        book.save()  
        # will save as insert with the new '_id' retrieved from 'counter' collection


# Saving model using schema
book_schema = BookSchema()

class Book2(Resource):
    def put(self):
        args = parse.parse_args()
        book = book_schema.load(args)
        book.save()  
        # will not save, because `_id` is requirement is not satisfied.
        # that is, it is not automatically calling SequenceField function)

Same here! In my case the SequenceField is not a primary key, just a normal sequence number, and it still doesn't work. I have commented the field out for now (although this is not an option for you)

Did you figure something out, since you originally reported your issue?
