フラスコ アプリケーションにフラスコ メールを実装していますが、コンテキスト エラーが発生したアプリを取り除くことができません。どんな助けでも大歓迎です。構成ファイルに mail_server パラメータを配置しました。

/app.py - アプリは create_web_apis でインスタンス化されます

def create_app(config):
"""Creates an instance of the app according to `config`

:param config: An instance of :class:`flask.config.Config`

:returns: The configured application. This can be passed to a WSGI
  container.

"""
app = create_web_apis()

app.config.update(config)
mail = Mail(app)
...

/emails.py

from flask import current_app
from flask.ext.mail import Mail, Message


mail = Mail(current_app) 

def send_email(subject, sender, recipients, text_body, html_body):
    msg = Message(subject, sender = sender, recipients = recipients)
    msg.body = text_body
    msg.html = html_body
    mail.send(msg)

ここに完全なトレースがあります

たとえば、 を使用して、テスト内でアプリケーション コンテキストを提供する必要がありますapp.test_request_context。詳細は公式ドキュメントで読むことができます

これを試すことができます：

メール.py

from flask import current_app
from flask.ext.mail import Mail, Message

def send_email(subject, sender, recipients, text_body, html_body):
    mail = Mail(current_app) 
    msg = Message(subject, sender = sender, recipients = recipients)
    msg.body = text_body
    msg.html = html_body
    mail.send(msg)

test.py

import unittest
from app import create_app
from flask.ext.mail import Message
from emails import send_email

class AppTestCase(unittest.TestCase):
    def setUp(self):
       self.app = create_app()

    def test_mail(self):
        with self.app.test_request_context('/'):
            send_email("Hello",
                  sender="from@example.com",
                  recipients=["to@example.com"],
                  text_body='',
                  html_body='',
            )

if __name__ == '__main__':
    unittest.main()

注:

Mailでインスタンスを作成する場合は、 でapp.py同じことを繰り返さないでくださいemails.py。以下のようなもので十分です。

app.py

from flask import Flask

def create_app():
    app = Flask(__name__)
    return app

test.py

import unittest
from app import create_app
from flask.ext.mail import Message

class AppTestCase(unittest.TestCase):
    def setUp(self):
       self.app = create_app()

    def test_mail(self):
        with self.app.test_request_context('/'):
            self.app.mail.send(Message("Hello",
                  sender="from@example.com",
                  recipients=["to@example.com"]))

if __name__ == '__main__':
    unittest.main()

DebuggingServer で両方をテストできます

python -m smtpd -n -c DebuggingServer localhost:1025
