Django评论从发布/预览重定向

我正在实现django评论应用程序。 单击post而不是post页面时，重定向到当前页面的最佳方式是什么

我遵循了以下指南：

我的表单如下所示：

{% load comments i18n %}

<form action="{% comment_form_target %}" method="post">{% csrf_token %}
    {% if next %}<div><input type="hidden" name="next" value="{{ next }}" /></div>{% endif %}
        {% for field in form %}
            {% if field.is_hidden %}
                <div>{{ field }}</div>
            {% else %}
                {% if field.name != "email" and field.name != "url" %}
                    {% if field.errors %}{{ field.errors }}{% endif %}
                        <p
                            {% if field.errors %} class="error"{% endif %}
                            {% ifequal field.name "honeypot" %} style="display:none;"{% endifequal %}>
                            {{ field.label_tag }} {{ field }}
                        </p>
                {% endif %}
            {% endif %}
        {% endfor %}
    <p class="submit"><input type="submit" name="post" class="submit-post" value="{% trans "Post" %}" /></p>
</form>

def comment_posted( request ):
    if request.GET['c']:
        comment_id, post_id = request.GET['c'].split( ':' )
        post = Image.objects.get( pk=post_id )
        if post:
            return HttpResponseRedirect( post.get_absolute_url() )
    return HttpResponseRedirect( "/" )

urlpatterns = patterns('',
    url(r'^other/', include('other.urls')),
    url(r'^live/', include('live.urls')),
    url(r'^photo/', include('photo.urls')),
    url(r'^comments/posted/$', 'photo.views.comment_posted'),
    url(r'^comments/', include('django.contrib.comments.urls')),
    url(r'^search/', SearchView(template=None, searchqueryset=None, form_class=SearchForm), name='haystack_search'),

My URL.py看起来像：

{% load comments i18n %}

<form action="{% comment_form_target %}" method="post">{% csrf_token %}
    {% if next %}<div><input type="hidden" name="next" value="{{ next }}" /></div>{% endif %}
        {% for field in form %}
            {% if field.is_hidden %}
                <div>{{ field }}</div>
            {% else %}
                {% if field.name != "email" and field.name != "url" %}
                    {% if field.errors %}{{ field.errors }}{% endif %}
                        <p
                            {% if field.errors %} class="error"{% endif %}
                            {% ifequal field.name "honeypot" %} style="display:none;"{% endifequal %}>
                            {{ field.label_tag }} {{ field }}
                        </p>
                {% endif %}
            {% endif %}
        {% endfor %}
    <p class="submit"><input type="submit" name="post" class="submit-post" value="{% trans "Post" %}" /></p>
</form>

def comment_posted( request ):
    if request.GET['c']:
        comment_id, post_id = request.GET['c'].split( ':' )
        post = Image.objects.get( pk=post_id )
        if post:
            return HttpResponseRedirect( post.get_absolute_url() )
    return HttpResponseRedirect( "/" )

urlpatterns = patterns('',
    url(r'^other/', include('other.urls')),
    url(r'^live/', include('live.urls')),
    url(r'^photo/', include('photo.urls')),
    url(r'^comments/posted/$', 'photo.views.comment_posted'),
    url(r'^comments/', include('django.contrib.comments.urls')),
    url(r'^search/', SearchView(template=None, searchqueryset=None, form_class=SearchForm), name='haystack_search'),

我想我已经修改了我的观点。有什么想法吗

我的应用程序叫照片，我的模型叫图像

谢谢

我不明白你为什么需要发表评论。相反，我认为您应该修复下一个领域：

{% if next %}<div><input type="hidden" name="next" value="{{ next }}" /></div>{% endif %}

{%if next%}{%endif%}

这里，仅当设置了“next”上下文变量时，才会输出“next”隐藏输入。你的目标应该是：

• 如果可能的话，让next成为{{next}}
• 回退到已注释对象的绝对url

它可能看起来像：

<input type="hidden" name="next" value="{% if next %}{{ next }}{% else %}{{ form.target_object.get_absolute_url }}{% endif %}" />

这假设您的模型有一个正确定义的get\u absolute\u url方法

请注意，我通过阅读以下内容了解form.target_对象：

comment templatetag的代码，我注意到它将注释表单与目标对象作为第一个参数实例化，并

我注意到的注释表单的代码将传递的目标对象存储在target_object属性中，使得它在{{form}所在的任何地方都可用

我更新了原来的帖子。谢谢你从哪里得到的？comment_id，post_id=request.GET['c'].split（'：'）我更改了那一行，它现在将我带到一个空白页。下一步我该怎么做？还有什么？在我的更新中，我更喜欢form.target_对象而不是form.instance.content_对象。
