python - 从 ManyToMany 在 admin.py 中添加字段

Question

我想为每个与其对应的问题页面显示我的类(class)页面中有 4 个项目(“访问 1 访问 2 访问 3 访问 4”)

现在我似乎一次获得所有页面......我想要例如“你多大了？”这个问题。仅在管理面板“访问 1”中用访问 1 定义

My 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)

My 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)

为每个关联页面获取正确的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)
