我的数据库模型未显示在管理视图中

管理视图未显示模型。是的,我对django完全陌生。我对这个网站完全陌生。

型号。py公司

from django.db import models

PUBLISH_CHOICES = (

    ('draft','Draft'),
    ('publish','Publish'),
    ('private','Private'),
)

app_name = 'Blog'

class Blog(models.Model):
    id = models.BigAutoField(primary_key = True)
    title = models.CharField(max_length = 200)
    body = models.CharField(max_length = 500, null = True)
    publish = models.CharField(max_length = 120, choices = PUBLISH_CHOICES, default = 'draft')
