Nothing like that. As you noted above, you are getting the error about a missing table before Django ever gets a chance to start applying the migrations that would create that table. If you look at the traceback closely, you'll notice that in file "/usr/local/django/projectadmin/projectadmin/form_utils.py", line 15, in create_template_choices_field, you are iterating over a queryset while that module is being imported. Think about it – before it even starts to apply migrations, Django needs to import all your packages, so that it can determine what migrations it needs to apply. However, in the process of importing them, you are already executing database queries against those tables. It looks like you are generating a list of choices dynamically in a form field, based on some model. For cases like this, you should most likely be using a ModelChoiceField, which avoids the problem of import-time queries (as well as the problem that the list of choices will not be updated to reflect changes in the set of model objects unless you restart your server) by querying the database only when it's actually used.
