flask 的 Flask-Mail 扩展在应用程序工厂结构中不起作用

Question

What I am trying to do is to configure my flask-mail extension in application factory in order to send mail from different.py files but I am unable to do so.I know my configuration are right because I had same config settings when using single file structure __init__.py

from flask import Flask
from flask_mail import Mail,Message
def create_app():
    mail = Mail()
    app.config['MAIL_SERVER']='smtp.gmail.com'
    app.config['MAIL_PORT']=465
    app.config['MAIL_USE_SSL']=True
    app.config['MAIL_USERNAME'] = ''
    app.config['MAIL_PASSWORD'] = ''
    app.config['MAIL_DEFAULT_SENDER'] = ''
    app.config['MAIL_USE_TLS'] = False 
    mail.init_app(app)
    return app

and the file I am willing to send emails from: dev.py

from flask import *
@bp.route('/login',methods=['GET','POST'])
def login():
    if request.method == 'POST':
        emailid = request.form['emailid']
        msg = Message('Password Change', sender = '')
        msg.add_recipient(emailid)
        msg.html = "<b>MADHAV</b>"
        mail.send(msg)

The error I am receiving is following:

NameError: name 'Message' is not defined

Answer 1

By looking at the imports you forgot to add the Message object in there.

If that s the only error you get, the following line should solve the issue.

dev.py

from flask-mail import Message
