我用它来评论网址：

url(r'^(?P<username>\w+)/post/(?P<slug>[\w-]+)/comments/', include('fluent_comments.urls')),

我的模板：

<div class="mdl-card__title" style="margin: 0 auto;">
                          <h2 class="mdl-card__title-text">{{ post.title }}</h2>
                        </div>
                        <div class="mdl-card__supporting-text" style="margin:0 auto;">
                         <p> Content : {{ post.content|linebreaksbr }}</p>
                         <p>

                         <a href="{{ f.file.url }}">{{ f.filename }}</a>
             <br>
                         {% endfor %}
                        {% endif %}
                         </p>
                         <p>
                        {{ post.post_type }}
                        </p>
                        {{ post.timestamp|timesince }} ago by {{ post.user }}
                        </div>
             {% if author %}
                        <div class="mdl-card__actions mdl-card--border">
                          <a class="mdl-button mdl-button--colored mdl-js-button mdl-js-ripple-effect mdl-button--colored" data-upgraded=",MaterialButton,MaterialRipple"  href="/{{ request.user.username }}/post/{{ post.slug }}/edit/">Edit Post</a>

                        </div>
              {% endif %}

                    </div>
          {% render_comment_list for object %}
          {% render_comment_form for object %}
                </div>

            </div>
        </div>

Answer 1

由于您指定的网址而发生错误。您fluent_comments.urls中包含的^(?P<username>\w+)/post/(?P<slug>[\w-]+)/comments/中的任何已命名网址都需要传递username和slug个对象。

当django-fluent-comments尝试渲染时 {% render_comment_form for object %}它会使用反向网址标记，但它没有传递username或slug个对象。

相反，您可以执行django-fluent-comments作者suggested的操作，并将以下内容添加到url.py

urlpatterns += patterns('',
    url(r'^blog/comments/', include('fluent_comments.urls')),
)

或删除username和slug个对象。

如果您确实要添加它们，则可以覆盖django-fluent-comments中的模板，以便使用网址名称的每个url标记都会传递username和{{1}对象。

有关详细信息，请查看Django Urls部分。
