    <p>I had the same issue as the user in this question but the <a href="https://stackoverflow.com/a/4119150/2270375">answer</a> unfortunately did not resolve anything. A few comments about what happened when I followed the given directions:</p> <p>When I tried the <code>--delete-ghost-migrations</code> command I got an error</p> <p><code>The app 'tixeng' does not appear to use migrations.</code></p> <p>I moved forward with the directions and initialized migrations for the app. Then I tried the <code>--delete-ghost-migrations</code> again</p> <pre><code>/Users/AaronPardes/Dropbox/Python/home_repos/squidtix/squidtix/virtualenvironments/squidtixENV/lib/python2.7/site-packages/django/utils/hashcompat.py:9: DeprecationWarning: django.utils.hashcompat is deprecated; use hashlib instead DeprecationWarning) Running migrations for tixeng: - Nothing to migrate. - Loading initial data for tixeng.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
