Wagtail

Question

我没有将 Wagtail 用于所有页面，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 等来自定义 wagtail 的安装。这意味着我在主应用程序文件夹中没有 models.py。出于某种原因，这也意味着新闻页面位于 pages/news 而不是 /news.

我想在此主页上显示帖子，但已将名称更改为来自博客的新闻，并且没有使用主页模型，我对如何实现这一点感到困惑。我在想我应该能够添加到 views.py 中的 "context" 来实现这一点，但无论我尝试了什么似乎都没有用。

我是新手，我确定我错过了一些东西，但我在学习这些东西时很开心，并且非常感谢任何指导来完成这项工作。

这是 news/models.py:

from django import forms
from django.db import models

# New imports added for ClusterTaggableManager, TaggedItemBase, MultiFieldPanel

from modelcluster.fields import ParentalKey, ParentalManyToManyField
from modelcluster.contrib.taggit import ClusterTaggableManager

from django.core.paginator import Paginator, EmptyPage, PageNotAnInteger

@register_snippet
class NewsCategory(models.Model):
    name = models.CharField(max_length=255)
    icon = models.ForeignKey(
        'wagtailimages.Image', null=True, blank=True,
        on_delete=models.SET_NULL, related_name='+'
    )

    panels = [
        FieldPanel('name'),
        ImageChooserPanel('icon'),
    ]

    def __str__(self):
        return self.name

    class Meta:
        verbose_name_plural = 'news categories'


class NewsIndexPage(Page):
    intro = RichTextField(blank=True)

    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)
        except EmptyPage:
            # If page is out of range (e.g. 9999), deliver last page of results.
            blogpages = paginator.page(paginator.num_pages)

        # make the variable 'resources' available on the template
        context['blogpages'] = blogpages

        return context


class NewsPageTag(TaggedItemBase):
    content_object = ParentalKey('NewsPage', related_name='tagged_items')

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

class NewsPage(Page):
    date = models.DateField("Post date")
    intro = models.CharField(max_length=250)
    body = RichTextField(blank=True)
    tags = ClusterTaggableManager(through=NewsPageTag, blank=True)
    categories = ParentalManyToManyField('news.NewsCategory', blank=True)

    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 中我定义了主页：

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

重新发布评论中的讨论，因为它解决了问题。

关于NewsIndexPage的URL请看urls.py。我怀疑您使用 url(r'pages', include(wagtail_urls)) 而不是 url(r'', include(wagtail_urls)) 来从根目录提供 Wagtail 页面。但是请确保在所有香草 Django 路由之后添加它，否则它会拦截所有内容。

关于在主页上显示新闻文章，请尝试将 context['news'] = NewsPage.objects.live().order_by('-first_published_at') 添加到 get_context_data。这将在模板中作为 news.
