Flask import app from parent directory

I have an app structured like so:

name
    -app.py
    -__init__.py
    -folder1
            -views.py
            -models.py
            -__init__.py

The content of my app.py:

from flask import Flask
from flask_cors import CORS

app = Flask(__name__)
CORS(app)

if __name__ == '__main__':
    app.run('0.0.0.0')

And init.py in the name folder is:

from app import app

How would I import this app into views.py? Currently, I'm using 

from name import app
from models import Class1
app.add_url_rule('/', view_func=Class1.as_view('class1'))

, but then when I run the app it returns a 404 error.

This is what I did to my apps:

In __init__.py:

from .app import app

with app.app_context():
    from .folder1 import models, views  # noqa

In folder1/views.py:

from flask import current_app as app
# then use `app` as usual
from .models import Class1
app.add_url_rule('/', view_func=Class1.as_view('class1'))

The "app_context()" injects the current app object into the current_app proxy. Read this to understand the mechanism.

Also it is recommended to explicitly use relative imports (with the extra dots ".").
