无法使用django评论框架在django中获取评论表单
我正在尝试将django评论应用程序与我自己的名为“blog”的应用程序集成。但是，当我试图获得评论表时，我得到'无'而不是模型表格。
下面是我的“home.html”模板代码，我希望我的表单出现。

请帮我解决这个问题。如果需要任何其他信息，请告诉我。

答案 0 :(得分：0)
查看the documentation for get_comment_form，看起来在使用此标记时必须包含BlogPost的ID：
{% get_comment_form for blog.blogpost last_element.id as comment_form %}
