Question

我没有在所有页面上使用Wagtail，而是将Wagtail添加到基于Edge v2的现有站点。我通过创建一个新闻应用程序（而不是博客应用程序）并将页面名称更改为NewsIndexPage等来定制wagtail的安装。这意味着我在主app文件夹中没有models.py。出于某种原因，这也意味着新闻页面是页面/新闻而不是/ news。

我想在这个主页上显示帖子但是已经将名称更改为来自博客的新闻，而不是使用HomePage模型我对如何实现这一点感到困惑。我认为我应该能够添加到views.py中的“上下文”来实现这一点，但无论我尝试过什么似乎都不起作用。

成为新人我确信我错过了一些东西，但我学到了很多乐趣，并且非常感谢任何指导这项工作。

这是news / models.py:

from django import forms

# New imports added for ClusterTaggableManager, TaggedItemBase, MultiFieldPanel

from modelcluster.fields import ParentalKey, ParentalManyToManyField

        'wagtailimages.Image', null=True, blank=True,
        on_delete=models.SET_NULL, related_name='+'
    )

    panels = [

    def get_context(self, request):
        context = super(NewsIndexPage, self).get_context(request)

        # Get the full unpaginated listing of resource pages as a queryset -
        # replace this with your own query as appropriate
        blogpages = self.get_children().live().order_by('-first_published_at')

        paginator = Paginator(blogpages, 6) # Show 6 resources per page

        page = request.GET.get('page')
        try:
            blogpages = paginator.page(page)
        except PageNotAnInteger:
            # If page is not an integer, deliver first page.
            blogpages = paginator.page(1)

class NewsTagIndexPage(Page):

    def get_context(self, request):

        # Filter by tag
        tag = request.GET.get('tag')
        blogpages = NewsPage.objects.filter(tags__name=tag)

        # Update template context
        context = super(NewsTagIndexPage, self).get_context(request)
        context['blogpages'] = blogpages
        return context

    def main_image(self):
        gallery_item = self.gallery_images.first()
        if gallery_item:
            return gallery_item.image
        else:
            return None

    search_fields = Page.search_fields + [
        index.SearchField('intro'),
        index.SearchField('body'),
    ]

    content_panels = Page.content_panels + [
        MultiFieldPanel([
            FieldPanel('date'),
            FieldPanel('tags'),
            FieldPanel('categories', widget=forms.CheckboxSelectMultiple),
        ], heading="News information"),
        FieldPanel('intro'),
        FieldPanel('body'),
        InlinePanel('gallery_images', label="Gallery images"),

class NewsPageGalleryImage(Orderable):
    page = ParentalKey(NewsPage, related_name='gallery_images')
    image = models.ForeignKey(
        'wagtailimages.Image', on_delete=models.CASCADE, related_name='+'
    )
    caption = models.CharField(blank=True, max_length=250)

    panels = [
        ImageChooserPanel('image'),
        FieldPanel('caption'),
    ]

在mysite / views.py中我定义了HomePage：

from django.views import generic
from contact.forms import ContactForm

class HomePage(generic.TemplateView):
    template_name = "home.html"

    def get_context_data(self, *args, **kwargs):
        context=super(HomePage, self).get_context_data(*args, **kwargs)
        context['form'] = ContactForm

        return context

从评论中重新发布讨论，因为它解决了问题。

关于NewsIndexPage的网址，请查看urls.py.我怀疑你有url(r'pages', include(wagtail_urls))而不是url(r'', include(wagtail_urls))，因为从根提供Wagtail页面。但是一定要在你所有的香草Django路线之后添加它，否则它会拦截所有东西。

至于在首页上显示新闻文章，请尝试将context['news'] = NewsPage.objects.live().order_by('-first_published_at')添加到get_context_data。这将在模板中以news形式提供。
