django错误：int（）以10为底的无效文字：b'01 / 12/1990'

Question

我在django应用程序中创建了一个Profile和Blog模型。

这是下面的models.py文件：

     from django.db import models


     # Create your models here.

     class Profile(models.Model):
         name = models.CharField(max_length=30)
         description = models.TextField()
         number = models.CharField(max_length=10)
         dob = models.DateField()


     class Blog(models.Model):
         title = models.CharField(max_length=30)
         content = models.TextField()
         blog_document = models.FileField(upload_to='documents/', null=True, blank=True)

在管理面板中，对于配置文件模型：我想查看表中的两个或更多列，如下所示：

但是此行给我错误，因为我不知道如何在Profile表中显示多个列：

        def __str__(self):
             return '%s %s' % (self.name, self.number)

请帮助！在个人资料表（管理面板）中实现两个或多个字段的正确解决方案是什么？预先感谢！

更新：

    class ProfileAdmin(admin.ModelAdmin):
        list_display = ('name', 'description', 'number', 'dob')


    admin.site.register(Profile, ProfileAdmin)


    class BlogAdmin(admin.ModelAdmin):
        list_display = ('title', 'content')


    admin.site.register(Blog, BlogAdmin)

这是引用通告：

标题：/ admin / mysite / profile /

中的ValueError
