我正在使用Django 1.8,我想开始使用Django的文件系统缓存,a per-view cache in the URLconf。
这是我的urls.py
:
urlpatterns = patterns(
'',
url(r'^api/1.0/spending$',
'frontend.views.views_api_spending.total_spending_on_substance',
name='total_spending'),
这就是我正在尝试的:
urlpatterns = patterns(
'',
url(r'^api/1.0/spending$',
cache_page(60 * 15)('frontend.views.views_api_spending.total_spending_on_substance'),
name='total_spending'),
但我收到一个错误:TypeError at /api/1.0/spending: 'str' object is not callable
。
如果我删除了引号,我会得到:NameError at /api/1.0/spending: name 'frontend' is not defined
。
如何调整我的urls文件以开始使用每个视图缓存?
答案 0 :(得分:0)
为此,您需要在total_spending_on_substance
中导入urls.py
视图功能,然后将total_spending_on_substance
视图功能传递给cache_page
装饰器而不是字符串< /强>
cache_page
是一个装饰器,它需要一个视图功能。因此,当你在URLconf中引用它时,用view_page包装视图函数total_spending_on_substance
。
您可以执行以下操作:
from frontend.views.views_api_spending import total_spending_on_substance # import the view function
urlpatterns = patterns(
'',
url(r'^api/1.0/spending$',
cache_page(60 * 15)(total_spending_on_substance), # pass function instead of string
name='total_spending'),
