Question

我在mydomain.com/gallery/album/2017上有类别过滤器

class Gallery(RoutablePageMixin,Page):
    short_description = models.CharField(max_length=300,blank=True)
    content_panels = Page.content_panels + [
        FieldPanel('short_description'),
        InlinePanel('image_gallery', label="image gallery"),
    ]

    def get_posts(self):
        return AlbumImageGallery.objects.all()

    @route(r'^albums/(?P<album>[-\w]+)/$')
    def post_by_category(self, request, album, *args, **kwargs):
        self.get_posts = self.get_posts().filter(album__slug=album)
        return Page.serve(self, request, *args, **kwargs)

    def get_context(self, request, *args, **kwargs):
        context = super(Gallery, self).get_context(request, *args, **kwargs)
        context['albums'] = Album.objects.all()
        context['album_image'] = AlbumImageGallery.objects.all()
        context['get_posts'] = self.get_posts
        context['gallery'] = self
        return context

在我的HTML中

<a href="{% routablepageurl gallery "post_by_category" each.slug %}"> {{each.album_name}}</a>

现在我想从我的其他页面获取mydomain.com/gallery/album/2017

class MymodelPage(Page):
    ...
    get_context():
        context['gallery_images'] = Image.objects.all()
        context['gallery'] = Gallery.objects.get()

MymodelPage.html

错误

NoReverseMatch at /media-corner/
Reverse for 'post_by_category' with arguments '('',)' not found. 1 pattern(s) tried: [u'albums/(?P<album>[-\\w]+)/$']

我想在我的Modal RoutablePageMixin上获取gallery url / slug 我试图传递url页面给我错误

Answer 1

检查each.slug的值。从错误消息（ with arguments '('',)'），似乎routablepageurl标记收到一个空字符串作为each.slug参数。（这不符合您的网址格式，因为它要求album slug至少包含一个字符。）

W - 在其他页面中获取页面类别的可路由页面
