g渲染索引页中的任何路径

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?

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)
