Django,模板上下文处理器 [英] Django, template context processors
问题描述
这是我如何通过以下:
在我的应用程序中制作了一个processor.py:
from myproject.myapp.models import Foo
def foos(request):
return {'foos':Foo.objects.all()}
在我的setting.py结尾我添加了这个:
TEMPLATE_CONTEXT_PROCESSORS =('myapp.processor.foos',)
最后我通过我的观点:
def index_view(request):
return render_to_response('index.html',{},context_instance = RequestContext(request))
和我的index.html模板:
< select id =select_foo>
{%foos in foos%}
< option value =/ {{foo.slug}}> {{foo.name}}< / option>
{%endfor%}
< / select>
最后我的网址:
(r'^ $','myapp.views.index_view'),
我的foos显示没有任何问题,但是我的media_url和其他上下文消失了。
可能是什么问题
当您指定时:
TEMPLATE_CONTEXT_PROCESSORS =('myapp.processor.foos',)
在您的设置文件中,您将覆盖Django的默认上下文处理器。为了扩展列表,您需要在设置中包含默认值:
TEMPLATE_CONTEXT_PROCESSORS =(
django.core.context_processors.auth,
django.core.context_processors.debug,
django.core.context_processors.i18n,
django .core.context_processors.media,
myapp.processor.foos,
)
注意,上面的设置是django 1.1的默认设置(加上处理器)。
I have a weird problem, I want to add a global query using context processors. This is how I did it by following:
made a processor.py in my app as such:
from myproject.myapp.models import Foo
def foos(request):
return {'foos': Foo.objects.all()}
and at the end of my setting.py I have added this:
TEMPLATE_CONTEXT_PROCESSORS = ('myapp.processor.foos',)
Lastly I pass my view as this:
def index_view(request):
return render_to_response('index.html', {}, context_instance=RequestContext(request))
and at my index.html template:
<select id="select_foo">
{% for foo in foos %}
<option value="/{{ foo.slug }}">{{ foo.name }}</option>
{% endfor %}
</select>
And lastly my url:
(r'^$', 'myapp.views.index_view'),
My foos display without any problem, however my media_url and other contexts are gone. What can be the issue
When you specify this:
TEMPLATE_CONTEXT_PROCESSORS = ('myapp.processor.foos',)
In your settings file, you are overriding the Django's default context processors. In order to extend the list, you need to include the default ones in your settings:
TEMPLATE_CONTEXT_PROCESSORS = (
"django.core.context_processors.auth",
"django.core.context_processors.debug",
"django.core.context_processors.i18n",
"django.core.context_processors.media",
"myapp.processor.foos",
)
Note, the settings above are the defaults (plus your processor) for django 1.1.
