将具有 heroku 数据库的 python flask 应用程序部署到 Z3115FB34DFCB5BA8AA049707C596B73Z3

Question

I was able to launch my flask app when it wasn't using the database yet. How do I set-up the database in heroku. I always run export DATABASE_URL=<URI> in the terminal whenever I run my flask app. I tried to follow tutorials online but nothing works so far.

This is my directory

directory

This is my Procfile:

web: gunicorn wsgi:app
heroku ps:scale web

This is my requirements.txt:

click==7.1.2
Flask==1.1.2
gunicorn==19.10.0
itsdangerous==1.1.0
Jinja2==2.11.2
MarkupSafe==1.1.1
Werkzeug==1.0.1

This is my wsgi.py when I placed my flask app inside the flask_qa folder:

from flask_qa import create_app

app = create_app()

This is the heroku log:

Maybe you need to set the app config using

app.config['SQLALCHEMY_DATABASE_URI'] = 'postgres://(you get the restof uri in heroku)
app.config['SQLALCHEMY_TRACK_MODIFICATIONS'] =False
db = SQLAlchemy(app)
