Question

我的想法是创建文章和评论的模型。用户启动评论时，他们可以直接创建数据，但是在实际操作中添加评论不会响应。

#views.py
def details(request, article_id):
    detail = LifeArticle.objects.get(id=article_id)
    comment = LifeComment.objects.get(article=detail)
    return render(request, 'lifedetail.html', locals())

def addcomment(request, article_id):
    article = LifeArticle.objects.get(id=article_id)
    if request.method == "POST":
        content = request.POST['content']
        r = LifeComment.create(article=article, user=request.user, content=content)
        msg = '添加成功'
        return render(request, 'lifedetail.html', locals())
    else:
        return render(request, 'lifedetail.html',)

#urls.py
urlpatterns = [
    url(r'^life/(?P<article_id>\d+)/', views.details),
    url(r'^article/life/(?P<article_id>\d+)/addcoment/', views.addcomment)
]

#lifedetail.html
{% if detail %}
<div id='article'>
<form action="/article/life/{{detail.id}}/addcoment/" method="POST">
{% csrf_token %}
    <tr>
        <td>{{ detail.title }}</td>
        <td>{{ detail.content }}</td>
        <td>{{ detail.user }}</td>
    </tr>
</div>
<div id="comment">
{% if comment %}
    <tr>
        <td>{{ comment.content }}</td>
        <td>{{ comment.user }}</td>
    </tr>
</div>
{% else %}
<p>暂无评论</p>
{% endif %}
<input type="text" name="content">
<input type="submit" value="提交">
</form>
{% else %}
<p>暂无文章</p>
{% endif %}
{{msg}}
</div>

这些是我的代码。现在我找不到原因了。我也在看Django2.2的文档来发现问题

我认为问题出在这一行：

r = LifeComment.create(article=article, user=request.user, content=content)

我认为您应该在此处使用objects

r = LifeComment.objects.create(article=article, user=request.user, content=content)

此外，您需要从上下文发送detail信息：

def addcomment(request, article_id):
    article = LifeArticle.objects.get(id=article_id)
    if request.method == "POST":
        # rest of the code
    else:
        return render(request, 'lifedetail.html', context={'detail':article})

我写了一种添加评论的方法，但是没有运行
