Flask: cannot import name 'app'
<p>Trying to run my python file <code>updater.py</code> to SSH to a server and run some commands every few set intervals or so. I'm using APScheduler to run the function <code>update_printer()</code> from <code>__init__.py</code>. Initially I got a <code>working outside of application context error</code> but someone suggested that I just import app from <code>__init__</code>.py. However it isn't working out so well. I keep getting a <code>cannot import name 'app'</code> error.</p>

<p><strong>app.py</strong></p>

<pre><code>from queue_app import app

if __name__ == '__main__':
    app.run(debug=True)
</code></pre>

<p><strong>__init__.py</strong></p>

<pre><code>from flask import Flask, render_template
from apscheduler.schedulers.background import BackgroundScheduler
from queue_app.updater import update_printer
app = Flask(__name__)
app.config.from_object('config')

@app.before_first_request
def init():
    sched = BackgroundScheduler()
    sched.start()
    sched.add_job(update_printer, 'interval', seconds=10)

@app.route('/')
def index():
    return render_template('index.html')
</code></pre>

<p><strong>updater.py</strong></p>

<pre><code>import paramiko
import json
from queue_app import app

def update_printer():
    ssh = paramiko.SSHClient()
    ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    ssh.connect(app.config['SSH_SERVER'], username = app.config['SSH_USERNAME'], password = app.config['SSH_PASSWORD'])

...
</code></pre>

<p><strong>File Structure</strong></p>

<pre><code>queue/
   app.py
   config.py
   queue_app/
      __init__.py
      updater.py
</code></pre>

<p><strong>Error</strong></p>

<pre><code>Traceback (most recent call last):
  File "app.py", line 1, in &lt;module&gt;
    from queue_app import app
  File "/Users/name/queue/queue_app/__init__.py", line 3, in &lt;module&gt;
    from queue_app.updater import update_printer
  File "/Users/name/queue/queue_app/updater.py", line 3, in &lt;module&gt;
    from queue_app import app
ImportError: cannot import name 'app'
</code></pre>

<p>What do I need to do be able to get to the app.config from updater.py and avoid a "working outside of application context error" if ran from APScheduler?</p>
