阅读全文是出错，我想应该是article为空。

class ArticleDetailView(LoginRequiredMixin, DetailView):
    model = Articles
    template_name = 'articles/article_detail.html'

    def get_context_data(self, **kwargs):
        data = super(ArticleDetailView, self).get_context_data()
        print(data)
        '''
        {'object': <Articles: 强烈推荐让你弯道超车的40个好习惯>,
         'articles': <Articles: 强烈推荐让你弯道超车的40个好习惯>,
          'view': <zanhu.articles.views.ArticleDetailView object at 0x7fc099f5b5f8>}
		'''
        return data

<p class="text-left">
	 <a href="{% url 'users:detail' article.user.username %}">{{ article.user.get_profile_name }}</a>
	发表于{{ article.created_at }}
</p>

当article改为articles时，详情页正常了。我看到视频的代码的确是article，不是复数。这里百思不得姐。

app_name = 'articles'

urlpatterns = [
    path('', views.ArticlesListView.as_view(), name='list'),
    path('write-news-article/', views.ArticlesCreateView.as_view(), name='write-new'),
    path('drafts/', views.DraftListView.as_view(), name='drafts'),
    path('<str:slug>/', views.ArticleDetailView.as_view(), name='article')
]

但取消评论的注释后，又一个错误。

Internal Server Error: /articles/Qiang-Lie-Tui-Jian-Rang-Ni-Wan-Dao-Chao-Che-De-40Ge-Hao-Xi-Guan/
Traceback (most recent call last):
省略
  File "/root/.virtualenvs/zanhu_venv/lib/python3.6/site-packages/django/contrib/contenttypes/models.py", line 27, in _get_opts
    model = model._meta.concrete_model
AttributeError: 'str' object has no attribute '_meta'

我代码如下：

THIRD_PARTY_APPS = [
    ''',
    'django_comments',
]

path('comments/', include('django_comments.urls')),

同样也迁移了数据。

{% load static comments crispy_forms_tags thumbnail %}

望大佬指正
