Django kann Kontext nicht in Shell rendern

Question

Dies ist, was ich versuche zu laufen. Wenn ich den Server laufen lasse und diese Zeilen in einer Ansicht ausführe und dann eine HttpResponse zurückschicke, dann läuft alles gut. Allerdings, wenn ich python manage.py shell laufen und dann versuchen, durch diese Linien laufen dann bekomme ich einen Fehler:

product = Product.objects.get(pk=4) 
template = loader.get_template('weekly-email.html') 
user = User.objects.get(pk=1) 
body = template.render(Context({ 
    'user': user, 
    'product': product, 
})) 

Ausgang:

bearbeiten: und hier ist mein settings.py:

# Build paths inside the project like this: os.path.join(BASE_DIR, ...) 
import os 

DEBUG = True 

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__))) 

SECRET_KEY = 'SECRET' 

ALLOWED_HOSTS = [] 
AUTH_USER_MODEL = 'crunch.User' 


STATICFILES_DIRS = (
    '/Users/croberts/testproj/static/', 
) 
# Application definition 

INSTALLED_APPS = (
    'django.contrib.admin', 
    'django.contrib.auth', 
    'django.contrib.contenttypes', 
    'django.contrib.sessions', 
    'django.contrib.messages', 
    'django.contrib.staticfiles', 
    'crunch', 
    'emailmanager',

DATABASES = { 
    'default': { 
     'ENGINE': 'django.db.backends.sqlite3', 
     'NAME': os.path.join(BASE_DIR, 'database'), 
    } 
} 

LANGUAGE_CODE = 'en-us' 
TIME_ZONE = 'MST' 
USE_I18N = True 
USE_L10N = True 
USE_TZ = False 

STATIC_URL = '/static/' 
MEDIA_ROOT = BASE_DIR+'/media/' 
MEDIA_URL = '/media/' 

Auch ich benutze django 1.8.

Answer 1

Dies ist ein bekanntes Problem und wird in 1.8.1 behoben.

der Zwischenzeit können Sie manuell eine Sprache in der Shell aktivieren, es zu beheben:

from django.utils.translation import activate 
activate('en') # or any language code 

UPDATE: 1.8.1 freigegeben wurde, so dass die beste Lösung auf die neueste 1.8.x zu aktualisieren ist Ausführung.
