我有烧瓶+ wtforms应用程序。我可以在login()中看到 用户对象存储为
if user:
if user.verify_password(form.password.data):
flash('You have been logged in')
user.logins += 1
db.session.add(History(user.uid))
db.session.commit()
session['user'] = user
现在我想要检索用户
if 'user' in session:
User=session.get('user')
print User.nickname ###<< how to retrieve specific object member?
它失败并显示如下消息:
Instance <User at 0x8e5a64c> is not bound to a Session; attribute refresh operation cannot proceed
答案 0 :(得分:10)
这很简单。如果要检索特定对象,只需在会话中添加变量的名称,例如session['nickname']
。
您可以通过session['nickname'] = nickname
。
在您的情况下,您可以将其更改为以下
if 'user' in session:
user = session['user']
print user
if 'nickname' in session:
nickname = session['nickname']
print nickname
这是我用于登录的功能的简化版本。
@app.route('/login', methods=['POST'])
def login():
"""Authenticate User"""
username = request.form['username'].strip()
nickname = request.form['nickname'].strip()
password = request.form['password']
try:
if Auth().VerifyLogin(username, password):
session['username'] = username
session['nickname'] = nickname
else:
# failed to login, do something.
except Exception as why:
app.logger.critical('.....')
