SQLAlchemy 如何在 Flask 中查询登录用户的数据库？

Question

I have a SQLite database with a table in my models.py that shortened looks like this

# models.py
class Buyers(db.Model, UserMixin):

    __tablename__ = 'buyers'

    id = db.Column(db.Integer, primary_key=True)
    usertype = db.Column(db.String(64))
    email = db.Column(db.String(64), unique=True, index=True, nullable=False)
    firstname = db.Column(db.String(64), index=True, nullable=False)

In my views.py, I have function that looks like this

# view.py
@buyers_blueprint.route('/welcome')
@login_required
def welcome_user():
    user = Buyers.query.filter_by(firstname).first()
    return render_template('welcome.html', user=user)

I am trying to query the database in my view.py so I can send the firstname to an html page and dynamically update that users page. I have importer the models.py into my views.py

How can I get the logged in user's name in a query so I can render it to my html?

Thank you so much.

Answer 1

So, I think I figured it out. If I import current_user from Flask_login , then I have access. So, I can use:

# view.py
@buyers_blueprint.route('/welcome')
@login_required
def welcome_user():
    user = current_user
    return render_template('welcome.html', user=user)

So, now I can just figure out how to give me first name only.
