django-1.8

I am using this code in my admin.py from django.db.models import get_models, get_app for model in get_models(get_app('myapp')): admin.site.register(model) But i get warning that get_models is deprecated How can i do that in django 1.8 This should work, from django.apps import apps apps.get_models() The get_models method returns a list of all installed models. You can also pass three keyword arguments include_auto_created , include_deferred and include_swapped . If you want to get the models for a specific app, you can do something like this. from django.apps import apps myapp = apps.get_app

Something went wrong on my migrations, I added a new datetimefield to a model then I used makemigrations and migrate. python manage.py makemigrations python manage.py migrate But after this the migrate got an "table already exists error". I supposed I could fake the migrations and start over, so I did python manage.py makemigrations --fake core Operations to perform: Apply all migrations: core Running migrations: Rendering model states... DONE Applying core.0001_initial... FAKED Applying core.0002_auto_20150525_1331... FAKED Applying core.0003_auto_20150525_1348... FAKED Applying core.0004

I upgraded recently to Django 1.8. In previous versions of Django, the following import was fine: from django.contrib.contenttypes.management import update_all_contenttypes But update_all_contenttypes appears to have been silently removed in Django 1.8 (it was there in 1.7.7). I'm not seeing anything in the 1.8 release notes about its removal... Does anyone know what the modern replacement is for that function? It's unclear why that function was removed in 1.8, but it appears that the modern replacement is to just re-invent that wheel: from django.apps import apps from django.contrib

I am trying to migrate from Django 1.6 to Django 1.8 . I was using South for managing migrations in Django 1.6. I have successfully created new migration files by python manage.py makemigrations . while running python manage.py migrate --fake-initial , I am getting this error Traceback (most recent call last): File "manage.py", line 39, in <module> execute_from_command_line(sys.argv) File "/home/jonty/.virtualenvs/squadrun/local/lib/python2.7/site- packages/django/core/management/__init__.py", line 338, in execute_from_command_line utility.execute() File "/home/jonty/.virtualenvs/squadrun

I am using this code to populate my database: import os def populate(): python_cat = add_cat('Python') add_page(cat=python_cat, title="Official Python Tutorial", url="http://docs.python.org/2/tutorial/") add_page(cat=python_cat, title="How to Think like a Computer Scientist", url="http://www.greenteapress.com/thinkpython/") add_page(cat=python_cat, title="Learn Python in 10 minutes", url="http://www.korokithakis.net/tutorials/python/") django_cat = add_cat(name="Django") add_page(cat=django_cat, title="Official Django Tutorial", url="http://djangoproject.com/en/1.5/intro/tutorial01/") add_page

I have the following models: class City(models.Model): ... class Census(models.Model): city = models.ForeignKey(City) date = models.DateTimeField() value = models.BigIntegerField() Now I'd like to annotate a City-queryset with the value of the latest Census. How do I achieve that? I have tried: City.objects.annotate(population=Max('census__date')) # --> annotates date and not value City.objects.annotate(population=Max('census__value')) # --> annotates highest value, not latest City.objects.annotate(population= Case( When( census__date=Max('census__date'), then='census__value') ) ) # -->

Take a look at this: $ pypy ./manage.py syncdb /usr/lib64/pypy-2.4.0/site-packages/django/core/management/commands/syncdb.py:24: RemovedInDjango19Warning: The syncdb command will be removed in Django 1.9 warnings.warn("The syncdb command will be removed in Django 1.9", RemovedInDjango19Warning) (cut) I ran a quick google search , but could not find the answer - what should I be using instead of syncdb ? syncdb is deprecated because of the migration system , introduced with django 1.7 . Now you can track your changes using makemigrations . This transforms your model changes into python code to
