django-1.9

When I change help_text or verbose_name for any of my model fields and run python manage.py makemigrations , it detects these changes and creates a new migration, say, 0002_xxxx.py . I am using PostgreSQL and I think these changes are irrelevant to my database (I wonder if a DBMS for which these changes are relevant exists at all). Why does Django generate migrations for such changes? Is there an option to ignore them? Can I apply the changes from 0002_xxxx.py to the previous migration ( 0001_initial.py ) manually and safely delete 0002_xxxx.py ? Is there a way to update previous migration

I have the following django model that contains JSONField: class RatebookDataEntry(models.Model): data = JSONField(blank=True, default=[]) last_update = models.DateTimeField(auto_now=True) class Meta: verbose_name_plural = 'Ratebook data entries' And data field contains this json: { "annual_mileage": 15000, "description": "LEON DIESEL SPORT COUPE", "body_style": "Coupe", "range_name": "LEON", "co2_gkm_max": 122, "manufacturer_name": "SEAT" } Can I sort queryset by one of the data fields? This query doesn't work. RatebookDataEntry.objects.all().order_by("data__manufacturer_name") As Julien

It has been obsolete since Django 1.7, which dropped support for Python 2.6, and is removed in 1.9 per the deprecation cycle. Use Python's import_module function instead: from importlib import import_module The reason you can import it from django.utils.module_loading is that importlib.import_module is imported in that module, it is not
