我正在尝试做什么 我有一个简单的视图,它将pk作为参数并执行操作。这个工作正常,直到pks大于999.现在他们返回404s。我正在努力解决这个问题。
我尝试了什么 我的观点如下:
def request_publication(request, pk):
...
article = News.all_news.get(pk=pk) # all_news is a manager including unpublished articles
article.status = article.HIDDEN_STATUS
article.save()
...
网址正则表达式是这样的:
regex=r'^request-publication/(?P<pk>\d+)/',
我也试过了:
regex=r'^request-publication/(?P<pk>\d{4})/',
这使得它在pks上失败&lt;如预期的那样1000,但仍不适用于pk&gt; 999。
完整的urls.py
是:
# core Django imports
from django.conf.urls import patterns, include, url
# local imports
from .models import News, Category, Attachment
from .views import (
NewsHomeView,
CategoryHomeView,
NewsDetailView,
NewsYearArchiveView,
NewsMonthArchiveView,
NewsDayArchiveView,
NewsListView,
NewsCreateView,
NewsUpdateView,
publish,
request_publication,
)
urlpatterns = patterns('',
url(
regex = r'^$',
view = NewsHomeView.as_view(),
name = "news_home",
),
url(
regex = r'^add/$',
view = NewsCreateView.as_view(),
name = 'news_add',
),
url(
regex = r'^update/(?P<pk>\d+)/$',
view = NewsUpdateView.as_view(),
name = 'news_update',
),
url(
regex = r'^(?P<slug>[-\w]+)/$',
view = CategoryHomeView.as_view(),
name = 'category_detail',
),
url(
regex = r'^tag/(?P<tag_slug>[-\w]+)/$',
view = NewsListView.as_view(),
name = 'news_tag_list',
),
url(
regex = r'^(?P<category>[-\w]+)/(?P<year>\d{4})/$',
view = NewsYearArchiveView.as_view(),
name = "year_archive",
),
url(
regex = r'^(?P<category>[-\w]+)/(?P<year>\d{4})/(?P<month>\w{3})/$',
view = NewsMonthArchiveView.as_view(),
name = "month_archive",
),
url(
regex = r'^(?P<category>[-\w]+)/(?P<year>\d{4})/(?P<month>\w{3})/(?P<day>\d{2})/$',
view = NewsDayArchiveView.as_view(),
name = "day_archive",
),
url(
regex = r'^(?P<category>[-\w]+)/(?P<year>\d{4})/(?P<month>\w{3})/(?P<day>\d{2})/(?P<slug>[-\w]+)/$',
view = NewsDetailView.as_view(),
name = "article",
),
url(
regex = r'^publish/(?P<pk>\d+)/$',
view = publish,
name = 'publish',
),
url(
regex = r'^request-publication/(?P<pk>\d+)/$',
view = request_publication,
name = 'request_publication',
),
)
从shell调用News.all_news.get(pk=1000)
可以很好地完成,all_news
是标准Django objects
管理器的别名,因为我已经使用自定义管理器覆盖了objects
。< / p>
我期待的是什么 我看不出有什么理由会失败。我希望视图能够成功返回。
实际发生的事情 标准404页。
限制 由于公司的限制,我无法单独升级到更新的Django。
问题(S) 有没有其他人经历过这个,你是如何解决它的?
答案 0 :(得分:6)
request-publication/1000
视图正在捕获year-archive
的请求,因为当三位数pk不匹配时,它与模式r'^(?P<category>[-\w]+)/(?P<year>\d{4})/$
匹配。
因此,您获得了404,因为您在1000年中没有发布与slug匹配的项目&#34; requests-publication&#34;。
