How to set environment variables in heroku-django project?
<p>I have this code in my settings.py..</p>

<pre><code>EMAIL_HOST = 'smtp.sendgrid.net'
EMAIL_HOST_USER = os.environ.get('EMAIL_HOST_USER')
EMAIL_HOST_PASSWORD = os.environ.get('EMAIL_HOST_PASSWORD')
</code></pre>

<p>I tried setting environment variable using this in heroku bash</p>

<pre><code>export EMAIL_HOST_USER=xxx
</code></pre>

<p>and also </p>

<pre><code>heroku config:set EMAIL_HOST_USER=xxx
</code></pre>

<p>None of the both method worked for me.
