从给定对象的所有站点获取Django注释

我使用Django站点框架在不同站点之间共享对象。这很好，因为我能够在模型中定义多对多关系

但是，在使用模板标记“render_comment_list”检索对象的注释（Django comments）时，我只得到那些发布在特定站点中的注释。这是意料之中的，但我也希望得到那些其他的评论，这些评论是针对多个站点共享的对象发布的

深入研究Django注释的代码，似乎这就是导致“问题”的方法：

def get_query_set(self, context):
    ctype, object_pk = self.get_target_ctype_pk(context)
    if not object_pk:
        return self.comment_model.objects.none()

    qs = self.comment_model.objects.filter(
        content_type = ctype,
        object_pk    = smart_unicode(object_pk),
        site__pk     = settings.SITE_ID,
    )

我的问题是：

• 更改行为的最简单方法是什么，以便模板标记“render_comment_list”显示对象的所有注释，而不仅仅是特定站点的注释
• 我是否需要创建另一个模板标记并复制粘贴99%的Django注释模板标记代码

谢谢

您不必复制并超过99%的模板标记代码，只需将

RenderCommentListNode

子类化，并覆盖发现问题的

get\u queryset\u方法

。然后复制

render\u comment\u list

函数，但使用子类

class RenderCommentListNodeAllSites(RenderCommnetListNode):
    def get_query_set(self, context):
        ctype, object_pk = self.get_target_ctype_pk(context)
        if not object_pk:
            return self.comment_model.objects.none()

        qs = self.comment_model.objects.filter(
            content_type = ctype,
            object_pk    = smart_unicode(object_pk),
        )

def render_comment_list_all_sites(parser, token):
    return RenderCommentListNodeAllSites.handle_token(parser, token)
register.tag(render_comment_list_all_sites)

谢谢阿拉斯代尔！我做了改变，它正在工作。为清晰起见，编写整个代码（现在可以了！）：

class RenderCommentListNodeAllSites(RenderCommentListNode):
    def get_query_set(self, context):
        ctype, object_pk = self.get_target_ctype_pk(context)
        if not object_pk:
            return self.comment_model.objects.none()

        qs = self.comment_model.objects.filter(
            content_type = ctype,
            object_pk    = smart_unicode(object_pk),
            #site__pk     = settings.SITE_ID,
        )

        # The is_public and is_removed fields are implementation details of the
        # built-in comment model's spam filtering system, so they might not
        # be present on a custom comment model subclass. If they exist, we
        # should filter on them.
        field_names = [f.name for f in self.comment_model._meta.fields]
        if 'is_public' in field_names:
            qs = qs.filter(is_public=True)
        if getattr(settings, 'COMMENTS_HIDE_REMOVED', True) and 'is_removed' in field_names:
            qs = qs.filter(is_removed=False)

        return qs

def render_comment_list_all_sites(parser, token):
    return RenderCommentListNodeAllSites.handle_token(parser, token)
register.tag(render_comment_list_all_sites)
