Может ли одно приложение на героку использовать cleardb другого приложения

/ 29 февраля 2020

Я хочу, чтобы мое приложение python flask связывалось с clearDB моего веб-приложения. Обе развернуть на Heroku. Я хочу знать, возможно ли это сделать.

Это некоторые из моих кодов. я использовал все Config Vars из веб-приложения. 

from flaskext.mysql import MySQL

app = Flask(__name__)
app.secret_key= 'secret key of web app'

# MySQL configurations
app.config['MYSQL_DATABASE_HOST'] = os.environ.get('DB_HOST')
app.config['MYSQL_DATABASE_PORT'] = 3306
app.config['MYSQL_DATABASE_USER'] = os.environ.get('DB_USER')
app.config['MYSQL_DATABASE_PASSWORD'] = os.environ.get('DB_PASSWORD')
app.config['MYSQL_DATABASE_DB'] = os.environ.get('DB_SCHEMA')

#init MySQL
mysql = MySQL()
mysql.init_app(app)

CHANNEL_ACCESS_TOKEN = os.environ.get('CHANNEL_ACCESS_TOKEN')
CHANNEL_SECRET = os.environ.get('CHANNEL_SECRET')

line_bot_api = LineBotApi(CHANNEL_ACCESS_TOKEN)
handler = WebhookHandler(CHANNEL_SECRET)

# Handle the messages and do the responding actions here.
@handler.add(MessageEvent, message=TextMessage)
def handle_message(event):
   conn = mysql.connect()
   c = conn.cursor()
   c.execute("SELECT detect FROM park ORDER BY id DESC LIMIT 1")
   lot1 = c.fetchone()
   c.close()
   conn.close()

это то, что я получил в журналах приложений.

Что я здесь не так делаю? Можно ли подключиться к чужой базе приложений на героку? Если да, подскажите, пожалуйста, как это сделать.
