How to resend letter if email not confirmed, FLASK? - flask

Question

Am trying to resend email to any one that not yet confirmed his account .
models.py
class Subscribers(Base):
id = db.Column(db.Integer, primary_key=True)
email = db.Column(db.String(50))
confirmed = db.Column(db.Boolean(), default=False)
def confirm(self, token):
s = Serializer(app.config['SECRET_KEY'])
try:
data = s.loads(token)
except:
return False
if data.get('confirm') != self.id:
return False
self.confirmed = True
db.session.add(self)
return True
def generate_confirmation_token(self, expiration=3600):
s = Serializer(app.config['SECRET_KEY'], expiration)
return s.dumps({'confirm': self.id})
def get_token(self, expiration=1800):
s = Serializer(app.config['SECRET_KEY'], expiration)
return s.dumps({'email': self.id}).decode('utf-8')
#staticmethod
def verify_token(token):
s = Serializer(app.config['SECRET_KEY'])
try:
data = s.loads(token)
except:
return None
id = data.get('email')
if id:
return User.query.get(id)
return None
This is the function where the confirmation process handled:
#app.route('/send-confirmation/<email>/<token>')
def confirm(token,email):
subre = Subscribers.query.filter_by(email=email).first()
if subre.confirmed:
flash('Э.почта уже подтверждена.')
return redirect(url_for('index'))
if subre.confirm(token):
subre.confirmed = True
db.session.add(subre)
db.session.commit()
send_email(subre.email, 'Благодарим Вас за подписку на наш сайт', 'auth/subscribe/thanks', subre=subre, token=token)
flash('Вы подтвердили свою электронную почту, спасибо!')
else:
flash('Ссылка для подтверждения является недействительным или истек.')
return redirect(url_for('index'))
Tell now everything is working very well, am trying to fetch each account that not yet confirmed by sending them another message asking them to confirm there account, here is the function :
#app.before_request
def resend_confirmation():
subscribers = Subscribers.query.filter_by(confirmed=False)
for sub in subscribers:
email = sub.email
token = email.generate_confirmation_token()
send_email(email, 'Подтверждение по электронной почте было отправлено Вам по электронной почте.',
'auth/email/resend', email=email, token=token)
Here am getting an error says:
AttributeError: 'unicode' object has no attribute 'generate_confirmation_token'
i tried to add __unicode__ function in the model but without avail .
Please any help .

You are trying to call generate_confirmation_token method on email, but you should use Subscribers instance:
#app.before_request
def resend_confirmation():
subscribers = Subscribers.query.filter_by(confirmed=False)
for sub in subscribers:
token = sub.generate_confirmation_token()
send_email(sub.email, 'Подтверждение по электронной почте было отправлено Вам по электронной почте.',
'auth/email/resend', email=email, token=token)
