从ManyToMany添加admin.py中的字段

Question

我想显示与其对应的每个问题页面我的课程页面中有4个项目（“访问1访问2访问3访问4”）

现在我似乎立刻得到了所有的页面...我想问一个问题，例如“你多大了？”这是在管理面板“仅访问1”

中此次访问1定义的

我可以为您分享截图，看看我现在得到了什么

  

我的models.py:

class Page(models.Model):
    title = models.CharField(max_length=30)


    def __str__(self):
        return self.title

class Question(models.Model):
    label = models.CharField(max_length=30)
    page = models.ManyToManyField(Page)

    def __str__(self):
            return self.label

class Reply(models.Model):
    question = models.ForeignKey(Question)
    user = models.ForeignKey(Personne)
    answer = models.CharField(max_length=30)
    creationDate = models.DateTimeField(default=datetime.datetime(2016, 1, 20, 15, 4, 21, 467165))

    def __str__(self):
        return str(self.answer)

  

我的admin.py：

class ReplyAdmin(admin.ModelAdmin):
    list_display = ["__str__", "user", "question", "creationDate", "get_pages",]

    def get_pages(self, objects):
        return "\n".join([page.title for page in Page.objects.all()])

    class Meta:
        model = Reply   
admin.site.register(Reply, ReplyAdmin)

为了获得每个关联网页的正确行，我必须面对的循环是什么

Answer 1

class ReplyAdmin(admin.ModelAdmin):
    list_display = ["__str__", "user", "question", "creationDate", "get_pages",]

    def get_pages(self, obj):
        return "\n".join([page.title for page in obj.question.page.all()])

    class Meta:
        model = Reply   
admin.site.register(Reply, ReplyAdmin)
