from django.db import models

# Create your models here.


class UserType(models.Model):
    name = models.CharField(max_length=32)


class UserInfo(models.Model):

    username = models.CharField(max_length=32)

• 修改settings.py 檔案:

# Application definition

INSTALLED_APPS = [
    `django.contrib.admin`,
    `django.contrib.auth`,
    `django.contrib.contenttypes`,
    `django.contrib.sessions`,
    `django.contrib.messages`,
    `django.contrib.staticfiles`,
    `cmdb`,
]

• 然後在Terminal 執行以下命令:
  (python manage.py makemigrations)
  (python manage.py migrate)

(python3) C:UsersAdministratorPycharmProjectss14django>python manage.py makemigrations
Migrations for `cmdb`:
  cmdbmigrations 001_initial.py:
    - Create model UserInfo
    - Create model UserType
    - Add field user_type to userinfo

(python3) C:UsersAdministratorPycharmProjectss14django>python manage.py migrate

• 在admin.py 修改程式碼如下(建立後臺管理):

from django.contrib import admin

from cmdb import models
# Register your models here.

admin.site.register(models.UserInfo)
admin.site.register(models.UserType)

在在Terminal 執行以下命令:
