<p>If you want to assert the call order of multiple patched functions you can attach mocks as attributes #attaching-mocks-as-attributes</p>

<p>Celery has a default configuration that removes every customized logs configuration. So if you change your logs root configuration the changes will only work on the django part. To allow this customization you should do this <code>worker_hijack_root_logger = False</code>: #std:setting-worker_hijack_root_logger</p>

<p>If you want the number of items in a QuerySet and are also retrieving model instances from it (for example, by iterating over it), it’s probably more efficient to use len(queryset) which won’t cause an extra database query like count() would.</p>

<p>When looking at your logs you may see <code>sql_error_code = 00000 LOG</code>. No need to worry this is Heroku's way to say "No error here". </p>

<p>If you use <code>iterator()</code> on a Django queryset, <code>prefetch_related()</code> calls will be ignored since these two optimizations do not make sense together (from "QuerySet API reference" section of Django docs)</p>
