[Django]-SQLAlchemy Model Django like Save Method?

You can extend your models with some simple crud methods to achieve something similar to Django ORM / ActiveRecord:

# SQLAlchemy db_session setup omitted
...

Model = declarative_base(name='Model')
Model.query = db_session.query_property()

class CRUD():

     def save(self):
         if self.id == None:
             db_session.add(self)
         return db_session.commit()

      def destroy(self):
          db_session.delete(self)
          return db_session.commit()

class User(Model, CRUD):
    __tablename__ = 'users'
    id = db.Column(db.integer, primary_key=True)
    email = db.Column(db.String(120), unique=True)

    def __init__(self, email):
        self.email = email

You can then save or destroy the model as needed:

user = User('example@example.com')
user.save()

Probably, you are looking for ORM events.

Take a look at instance events and session events.

Good news for you!

I created package for that. It implements Active Record pattern for SQLAlchemy.

See https://github.com/absent1706/sqlalchemy-mixins#active-record

It also has many very useful features such as Django lookups that span relationship, declarative eager load and readable print for SQAlchemy.

You can try Flask Diamond. It is similar with Django.
