我如何从html文件中的模型渲染我的变量，他们是在我在views.py
中使用class(DetailView)制作html链接slug之前提前渲染的
HTML FILE（product.html）
<h2 class="heading">{{ product.name }}</h2>
<div style="clear: both;"><br></div>
<div class="block">
<div class="img_preview">
<img src="{{ product.img }}">
<div class="categ">
{% for category in product.category.all %}
<a href=""><span>{{ category }}</span></a>
{% endfor %}
{# <div style="clear: both"><br></div> #}
</div>
</div>
<div id="links">
{% for link in links %}
<div class="download_link">
<a href="{{ links.link }}"><span>DOWNLOAD MIRROR NUMBER {{ links.number }}</span></a>
</div>
{% endfor %}
</div>
<div style="clear: both"></div>
<div id="games">
<div id="video_trailer">
<iframe width="560" height="317" src="{{ product.video_trailer }}" frameborder="0" gesture="media" allow="encrypted-media" allowfullscreen></iframe>
<div id="description">
<span class="title">Description</span>
<p>{{ product.description }}</p>
</div>
</div>
<div style="clear: both"><br></div>
<div id="system_requirements">
<span class="title">System Requirements</span><br>
<p>Processor: {{ product.processor }}<br>

Graphic Card: {{ product.video }}<br>
<br>
Memory: {{ product.ram }}<br>
<br>
Disk Space: {{ product.disk_space }}<br>
<br>
OS: {{ product.oS }}
</p>
</div>
</div>
<div id="screenshots">
{% for image in product_images %}
<div class="screenshot">
<img width="1920px" height="1080px" src="{{ image.image }}" >
</div>
{% endfor %}
</div>
</div>
</div>
<aside>
<div id="news">
<h2 class="heading">News</h2>
<div style="clear: both"><br></div>
{% for articles in news_articles %}
<div id="articles">
<div class="article">
<a href="{{ articles.article.get_absolute_url }}">

HTML文件仅显示使用{{ product.___ }}调用的产品变量，但不会像我调用的链接一样呈现其余部分：
{% for link in links %}
{{ link.link }}
{% endfor %}
或者喜欢我的文章...
我应该如何在我的页面上渲染所需的模型。

有不同的形式可以添加adicional＆＃39;变量＆＃39;使用DetailView (link)
例如：
class GameLink(DetailView):
def get_object(self):
return get_object_or_404(Product, slug__iexact=self.kwargs['slug'])
def links(self):
return ProductDownload.objects.filter(is_active=True, product=self.object)
在product.html中：
{% for link in view.links %}
<div class="download_link">
<a href="{{ link.link }}"><span>DOWNLOAD MIRROR NUMBER {{ links.number }}</span></a>
</div>
{% endfor %}
如果您不想更改HTML，而不是声明＆＃34; def链接（自我）＆＃34;：
class GameLink(DetailView):
def get_object(self):
return get_object_or_404(Product, slug__iexact=self.kwargs['slug'])
def get_context_data(self, **kwargs):
context = super(GameLink, self).get_context_data(**kwargs)
context['links'] = ProductDownload.objects.filter(is_active=True, product=self.object)
return context
