使用{％include％}的内容未出现在详细页面Django上

Question

更新＃4

问题：我一直无法在我的详细页面视图中显示内容，具体而言，此内容位于名为slider.html和sidebar.html的两个单独的html文件中，这些文件正在使用{ Django中的{1}}。

状态： 问题仍未解决，周四上次更新。 12月18日，上午11点。

• 我对{% include %}和models.py
进行了更改
• 是的，detailed.html页面上有空的div，上面有类
• 我在主帖中包含了我的views.py。

views.py

detailed.html

的 models.py

from django.views import generic
from . import models 
from .models import FullArticle

# Create your views here.
class BlogIndex(generic.ListView):
    queryset = models.FullArticle.objects.published()
    template_name = "list.html" 
    randomArticle = FullArticle.objects.order_by('?').first()

class BlogDetail(generic.DetailView):
    model = models.FullArticle
    template_name = "detailed.html"

的 detailed.html

from django.db import models
from django.core.urlresolvers import reverse

# Create your models here.
class FullArticleQuerySet(models.QuerySet):
    def published(self):
        return self.filter(publish=True)

class FullArticle(models.Model):
    title = models.CharField(max_length=150)
    author = models.CharField(max_length=150)
    slug = models.SlugField(max_length=200, unique=True)
    pubDate = models.DateTimeField(auto_now_add=True)
    updated = models.DateTimeField(auto_now=True)
    category = models.CharField(max_length=150)
    heroImage = models.CharField(max_length=250, blank=True)
    relatedImage =  models.CharField(max_length=250, blank=True)
    body =  models.TextField()
    publish = models.BooleanField(default=True)
    gameRank = models.CharField(max_length=150, blank=True, null=True)

    objects = FullArticleQuerySet.as_manager()

    def __str__(self):
        return self.title

    def get_absolute_url(self):
        return reverse("FullArticle_detailed", kwargs={"slug": self.slug})

    def get_context_data(self, **kwargs):
        context = super(BlogDetail, self).get_context_data(**kwargs)
        context['object_list'] = models.FullArticle.objects.published()
        return context

    class Meta:
        verbose_name = "Blog entry"
        verbose_name_plural = "Blog Entries"
        ordering = ["-pubDate"]

的 sidebar.html

<!-- This grabs the sidebar snippet -->
    {% include "sidebar.html" with object_list=object_list %}

    <div class="mainContent clearfix">
        <h1>{{object.title}}</h1>
        <p class="date">{{object.pubDate|date:"l, F j, Y" }}</p> | <p class="author">{{object.author}}</p>
        <img src="{{object.heroImage}}" alt="" class="largeImage">
        <div class="contentBlock">
            <img src="{{object.relatedImage}}" alt="" class="relatedImage">

            <p class="content">{{object.body|linebreaks}}</p>
        </div><!-- /.contentBlock -->

        <!-- This grabs the slider snippet -->
        {% include "slider.html" with object_list=object_list%}

    </div><!-- /.mainContent -->

urls.py （与名为博客的应用相关）

    <div class="navContent">
        {% for article in object_list|slice:":5" %}
        <div class="navItem">
            <div class="overlay">
            </div><!-- /.overlay -->
                <a href="{%url "detailed" slug=article.slug %}"><img src="{{article.relatedImage}}" alt="" class="navPicture"></a>
            <a href="{%url "detailed" slug=article.slug %}"><p class="navTitle">{{ article.title|truncatewords:"4" }}</p></a>
        </div><!-- /.navItem -->
        {% endfor %}
    </div><!-- /.navContent -->

get_context_data方法属于您的视图。如果你把它移到那里，你的侧边栏应该可以工作。

然而，通过使用上下文处理器可以更清晰地实现此目的。上下文处理器允许您为模板的所有提供某些数据，无论它们在何处。

在项目模块目录中创建context_processors.py，并使其看起来像这样：

# myproject/myproject/context_processors.py

from myapp.models import FullArticle


def sidebar_articles(request):
    """Return the 5 most recent articles for the sidebar."""
    articles = FullArticle.objects.all()[:5]
    return {'SIDEBAR_ARTICLES': articles}

您必须在settings.py中启用上下文处理器。通过添加TEMPLATE_CONTEXT_PROCESSORS default setting并将新的上下文处理器添加到底部来执行此操作。像这样：

# settings.py

TEMPLATE_CONTEXT_PROCESSORS = (
  "django.contrib.auth.context_processors.auth",
  "django.core.context_processors.debug",
  "django.core.context_processors.i18n",
  "django.core.context_processors.media",
  "django.core.context_processors.static",
  "django.core.context_processors.tz",
  "django.contrib.messages.context_processors.messages",
  "myproject.context_processors.sidebar_articles",
)

现在，您可以从任何模板中引用SIDEBAR_ARTICLES。您的sidebar.html可以改写为：

<!-- myapp/templates/detailed.html -->

<div>
  {% for article in SIDEBAR_ARTICLES %}
  <h1>{{ article.title }}</h1>
  and so on ...
  {% endfor %}
</div>

Answer 2

我认为有必要将正确的参数传递给您所包含的模板。有关更多文档，请参阅https://docs.djangoproject.com/en/dev/ref/templates/builtins/#include。

模板看起来像：{% include "sidebar.html" with article=object %}

更新1
在阅读了关于detailview的文档后，我的以下建议 （https://docs.djangoproject.com/en/1.7/ref/class-based-views/generic-display/#detailview）您的上下文似乎只包含object。因此，我们必须将此传递给此包含的滑块模板。

{% include "slider.html" with article=object %}

侧边栏模板中的问题是您的上下文中没有object_list。您可以将其添加到DetailView中，如示例中所示。所以方法看起来像。

def get_context_data(self, **kwargs):
    context = super(BlogDetail, self).get_context_data(**kwargs)
    context['object_list'] = models.FullArticle.objects.published()
    return context

模板的包含应该如下。

{% include "sidebar.html" with object_list=object_list %}

Answer 3

注意您正确地将上下文传递给模板。但可能你必须在＆＃39; {{＆＃39;括号和变量名称。防爆。 {{article.title}}
