 SQLAlchemy-Utils provides various utility classes and functions for SQLAlchemy.
 
+ScalarList
+----------
+
+ScalarList type provides convenient way for saving multiple scalar values in one
+column. ScalarList works like list on python side and saves the result as comma-separated list
+in the database (custom separators can also be used).
+
+Example ::
+
+
+    from sqlalchemy_utils import ScalarList
+
+
+    class User(Base):
+        __tablename__ = 'user'
+        id = db.Column(db.Integer, autoincrement=True)
+        hobbies = db.Column(ScalarList())
+
+
+    user = User()
+    user.hobbies = [u'football', u'ice_hockey']
+    session.commit()
+
+
+You can easily set up integer lists too:
+
+::
+
+
+    from sqlalchemy_utils import ScalarList
+
+
+    class Player(Base):
+        __tablename__ = 'player'
+        id = db.Column(db.Integer, autoincrement=True)
+        points = db.Column(ScalarList(int))
+
+
+    player = Player()
+    player.points = [11, 12, 8, 80]
+    session.commit()
+
