POSouth 0.8.3 upgrade causes DeserializationError
text
Body
copied!<p>I have a Django 1.5.5 project that uses South 0.8.2. Everything works great -- including migration using South. When I attempt to upgrade this project to South 0.8.3, I get the following error when I run <code>python manage.py migrate</code>:</p> <pre><code>(VBEZ)vagrant@vagrant-ubuntu-precise-64:/vagrant$ python manage.py migrate Running migrations for django_mailbox: - Nothing to migrate. - Loading initial data for django_mailbox. Installed 3 object(s) from 1 fixture(s) Running migrations for djcelery: - Nothing to migrate. - Loading initial data for djcelery. DeserializationError: Problem installing fixture 'initial_data.json': Invalid model identifier: 'sites.site' </code></pre> <p><strong>What has happened?</strong></p> <p>Here is my <code>initial_data.json</code> file:</p> <pre><code>[ { "pk": 1, "model": "sites.site", "fields": { "domain": "0.0.0.0:5000", "name": "Project (Development)" } }, { "pk": 2, "model": "sites.site", "fields": { "domain": "project-staging.example.com", "name": "Project (Staging)" } }, { "pk": 3, "model": "sites.site", "fields": { "domain": "project.example.com", "name": "Project" } } ] </code></pre> <p>Here is what a successful migration using South 0.8.2 looks like:</p> <pre><code>Running migrations for django_mailbox: - Nothing to migrate. - Loading initial data for django_mailbox. Installed 3 object(s) from 1 fixture(s) Running migrations for djcelery: - Nothing to migrate. - Loading initial data for djcelery. Installed 3 object(s) from 1 fixture(s) Running migrations for taggit: - Nothing to migrate. - Loading initial data for taggit. Installed 3 object(s) from 1 fixture(s) Running migrations for eee_core: - Nothing to migrate. - Loading initial data for eee_core. Installed 3 object(s) from 1 fixture(s) Running migrations for core: - Nothing to migrate. - Loading initial data for core. Installed 3 object(s) from 1 fixture(s) </code></pre> <p>Things I have looked at/tried:</p> <ul> <li><code>django-contrib-sites</code> is in my `INSTALLED_APPS'</li> <li>Migration works fine if the <code>initial_data.json</code> file is removed.</li> <li>If I run migrations individually, they run fine. Example <code>python manage.py migrate myapp</code>.</li> <li>I have submitted a ticket: <a href="http://south.aeracode.org/ticket/1324">http://south.aeracode.org/ticket/1324</a></li> </ul> <p>Thanks.</p>
