在执行django后台管理时，登陆到http://127.0.0.1:8000/admin/，进入页面后没有对应的字段显示。请解决？

 

代码：

models.py

from django.db import models

# Create your models here.
#发布会表
from django.db import models
class Event(models.Model):
    name = models.CharField(max_length = 100)  #发布会标题
    limit = models.IntegerField()              #参加人数
    status = models.BooleanField()               #状态
    address = models.CharField(max_length = 200) #地址
    start_time = models.DateTimeField('events time') #发布会时间
    create_time = models.DateTimeField(auto_now = True) #创建时间

    def __str__(self):
        return self.name

#嘉宾表
class Guest(models.Model):
    event = models.ForeignKey(Event) #关联发布会ID
    realname = models.CharField(max_length = 64) #姓名
    phone = models.CharField(max_length = 16) #手机号
    email = models.EmailField() #邮箱
    sign = models.BooleanField() #签到状态
create_time = models.DateTimeField(auto_now = True) #创建时间，自动获取当前时间

class Meta:
    unique_together = ('event','phone')

def __str__(self):
    return self.realname
# Create your models here.
from django.conf import settings

class Article(models.Model):
    """文章"""
    STATUS_CHOICES = (
        ('d', '草稿'),
        ('p', '发表'),
    )
    COMMENT_STATUS = (
        ('o', '打开'),
        ('c', '关闭'),
    )
    TYPE = (
        ('a', '文章'),
        ('p', '页面'),
    )
    title = models.CharField('标题', max_length=200, unique=True)
    body = models.TextField('正文')
    pub_time = models.DateTimeField('发布时间', blank=True, null=True)
    status = models.CharField('文章状态', max_length=1, choices=STATUS_CHOICES, default='p')
    comment_status = models.CharField('评论状态', max_length=1, choices=COMMENT_STATUS, default='o')
    type = models.CharField('类型', max_length=1, choices=TYPE, default='a')
    views = models.PositiveIntegerField('浏览量', default=0)
    author = models.ForeignKey(settings.AUTH_USER_MODEL, verbose_name='作者', on_delete=models.CASCADE)
    article_order = models.IntegerField('排序,数字越大越靠前', blank=False, null=False, default=0)


    def __str__(self):
        return self.title

    class Meta:
        ordering = ['-article_order', '-pub_time']
        verbose_name = "文章"
        verbose_name_plural = verbose_name
        get_latest_by = 'created_time'

 

admin.py

from django.contrib import admin
from sign.models import Event,Guest

# Register your models here.
admin.site.register(Event)
admin.site.register(Guest)

 

登陆显示页面如下：

 Django模型中的admin后台管理无法显示字段

 

 

 

 

实际应该显示：
