我在 django 中使用 mongoengine。我想创建一个 objectid，我可以将其插入到公司集合的嵌套对象批发商中

class wholesaler(EmbeddedDocument):
    wid                 =   ObjectIdField()
    name                =   StringField(required = True,min_length = 3)

class firm(Document):
    name                = StringField(required=True)
    wholesalers         = ListField(EmbeddedDocumentField(wholesaler))

在视图.py

wholesaler1 = wholesaler(wid = ??
                         ,name = '')
