Question 2: Consider the below flask_sqlalchemy data models “Product”…

1class Product(db.Model):
2   __tablename__ = "product"
3   id = db.Column(db.Integer, primary_key=True)
4   name = db.Column(db.String, nullable=False)
5
6class Supplier(db.Model):
7   __tablename__ = "supplier"
8   id = db.Column(db.Integer, primary_key=True)
9   name = db.Column(db.String, nullable=False)
10   address = db.Column(db.String, nullable=True)
11
12class Supply(db.Model):
13   __tablename__ = "supply"
14   id = db.Column(db.Integer, primary_key=True)
15   product_id = db.Column(db.Integer, db.ForeignKey("product.id"))
16   supplier_id = db.Column(db.Integer, db.ForeignKey("supplier.id"))
