获取查询中所有值的属性 sqlalchemy

Question

My database model is below: Users -->

class Users(db.Model):
   __tablename__ = 'users'
   id = db.Column(db.Integer(), primary_key=True)
   name = db.Column(db.String(length=100), nullable=False, unique=False)
   email = db.Column(db.String(length=30), nullable=False, unique=True)
   password_hash = db.Column(db.String(length=30),nullable=False,unique=False)
   isCorrect= db.Column(db.Boolean(),nullable=False, unique=False)

I'm trying to query specifically all values of isCorrect for True and access the name and email of the query. Here is my query below:

check = Users.query.filter_by(isCorrect=True)

How can I add an additional method at the end of my query to get the name and email values?

I tried looping through the query as shown below:

for name in (Users.query.filter_by(isCorrect=True).all()):
   names = list(Users.query.filter_by(isTutor=True).first())

However, I got this error:

TypeError: 'Users' object is not iterable

I also tried converting the query into a list, but I got the same error.

How can a list of all the attributes of a single query in SQLACHEMY (specifically flask extension)?

Thanks for your help!

Answer 1

all() returns the results of the query as a Python list .

# Get all users whose isCorrect column is True
for user in Users.query.filter_by(isCorrect=True).all():
    # user is an instance of your Users class
    print(user.name)
    print(user.email)
    print(user.isCorrect)
