How to make migrations for a reusable Django app? : <p>I am making a reusable Django app without a project. This is the directory structure:</p>

<pre><code>/
/myapp/
/myapp/models.py
/myapp/migrations/
/myapp/migrations/__init__.py
</code></pre>

<p>When I run <code>django-admin makemigrations</code> I get the following error:</p>

<pre><code>django.core.exceptions.ImproperlyConfigured: Requested setting DEFAULT_INDEX_TABLESPACE, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.
</code></pre>

<p>Obviously, this is because I don't have a settings module configured, because this is a reusable app. However, I would still like to ship migrations with my app. How can I make them?</p>
