Python django行为教程

这三条线与

was_published_recently

class QuestionAdmin(admin.ModelAdmin):
# ...
    list_display = ('question_text', 'pub_date', 'was_published_recently')

不工作，当我显示adminPoll时，什么都没有发生

class QuestionAdmin(admin.ModelAdmin):
# ...
    list_display = ('question_text', 'pub_date', 'was_published_recently')

django 1.6.5、python 2.7.6、ubuntu 14.04

class Poll(models.Model):
    # ...
    def was_published_recently(self):
        return self.pub_date >= timezone.now() - datetime.timedelta(days=1)
    was_published_recently.admin_order_field = 'pub_date'
    was_published_recently.boolean = True
    was_published_recently.short_description = 'Published recently?'

class QuestionAdmin(admin.ModelAdmin):
# ...
    list_display = ('question_text', 'pub_date', 'was_published_recently')

有什么帮助吗？

che如果您将最近发布的内容添加到列表显示中：

class QuestionAdmin(admin.ModelAdmin):
# ...
    list_display = ('question_text', 'pub_date', 'was_published_recently')

你能说得更具体些吗？“什么都没发生”是什么意思？对不起，当我说什么都没发生时，我的意思是浏览器没有显示在django教程之后应该做什么，列表的标题必须更改为“最近发布”，并且我必须能够按“发布日期”排序
