十七 Django 1.5.4 Sqlite3 Context Processors
settings.py
最终效果如图
一.context_processors.py
Django因此提供对全局 context处理器的支持。TEMPLATE_CONTEXT_PROCESSORS指定了总是使用哪些contextprocessors。这样就省去了每次使用RequestContext都指定processors的麻烦
from demo.apps.home.models import userProfile
import django
def user_image(request):
try:
imagen = None
user = request.user
up = userProfile.objects.get(user=user)
imagen = "/media/%s"%up.photo
except:
imagen = "/media/images/user.jpg"
return imagen
def my_processor(request):
context = {"django_version":django.get_version(),
"get_image_profile":user_image(request),
}
return context
