Question

In the Flask project, how to use MySQL and MongoDB, Sqlalchemy and MongoEngine at the same time?

from mongoengine import *
 import datetime
 
 class Page(Document):
 title = StringField(max_length=200, required=True)
 date_modified = ateTimeField(default=datetime.datetime.now)
 author = xxxx?  ?  ?  ?  [How does this relate to User?  ?  Manual?  】
 
 
 =======
 from sqlalchemy import Column, Integer, String
 class User(Base):
 __tablename__ = 'users'
 id = Column(Integer, primary_key=True)
 name = Column(String)
 fullname = Column(String)
 password = Column(String)

Answer 1

Two kinds of databases, can’t refer to each other. Let’s do it manually. Write Page a property, such as get_user or something.
