我需要使某些页面能够编写不依赖于站点结构的任意URL。
例如,我具有结构:
/
/blog
/blog/blogpost1
/blog/blogpost2
但是,例如,我需要将网址从/blog/blbogpost2
更改为/some/blogpost/url1
为此,我决定有机会对网站主页的任何URL进行处理。
class IndexPage(RoutablePageMixin, Page):
...
@route(r'^(?P<path>.*)/$')
def render_page_with_special_path(self, request, path, *args, **kwargs):
pages = Page.objects.not_exact_type(IndexPage).specific()
for page in pages:
if hasattr(page, 'full_path'):
if page.full_path == path:
return page.serve(request)
# some logic
但是现在,如果找不到此path
,但我需要将此请求返回给标准处理程序。我该怎么办?
答案 0 :(得分:2)
RoutablePageMixin
无法做到; Wagtail将URL路由和页面服务视为两个不同的步骤,一旦确定了负责服务页面的功能(对于RoutablePageMixin
,通过检查@route
中提供的URL路由即可完成),无法返回到URL路由步骤。
但是,可以通过overriding the page's route()
method(这是低级机制used by RoutablePageMixin
)来完成。您的版本看起来像这样:
from wagtail.core.url_routing import RouteResult
class IndexPage(Page):
def route(self, request, path_components):
# reconstruct the original URL path from the list of path components
path = '/'
if path_components:
path += '/'.join(path_components) + '/'
pages = Page.objects.not_exact_type(IndexPage).specific()
for page in pages:
if hasattr(page, 'full_path'):
if page.full_path == path:
return RouteResult(page)
# no match found, so revert to the default routing mechanism
return super().route(request, path_components)
