我想使用Django rest框架在python中声明新应用。
首先，我执行以下步骤：
cmd>django-admin startproject djrest .
cmd>cd djrest
cmd>django-admin startapp sarox
cmd>cd..
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql','NAME': 'sarox','USER': 'root','PASSWORD': '*******','HOST': 'localhost','PORT': '****',}
}
cmd>python manage.py migrate
cmd>python manage.py createsuperuser
cmd>py manage.py runserver 0.0.0.0:2281
然后我在Sarox_models.py目录下的sarox中声明了一个模型：
from django.db import models
class SaroxUsers(models.Model):
user_id = models.AutoField(db_column='User_id',primary_key=True) # Field name made lowercase.
salt = models.CharField(db_column='Salt',max_length=200,blank=True,null=True) # Field name made lowercase.
hash = models.CharField(db_column='Hash',null=True) # Field name made lowercase.
username = models.CharField(db_column='username',unique=True,max_length=15) # Field name made lowercase.
class Meta:
managed = False
db_table = 'sarox_users'
然后我将以下行添加到views.py目录下的sarox：
from djrest.sarox.Sarox_models import SaroxUsers
，然后在INSTALLED_APPS文件的settings.py配置类中创建一行。
这是我的INSTALLED_APPS配置类：
INSTALLED_APPS = [
'sarox.apps.SaroxConfig',...
]
我的新应用在sarox/apps.py
from django.apps import AppConfig
class SaroxConfig(AppConfig):
name = 'sarox'
但是当我运行python manage.py runserver 0.0.0.0:2281命令时，它会引发运行时错误：
E:\MyApps\Plot\djrest>python manage.py runserver 0.0.0.0:2281

当我删除新行时，在'sarox.apps.SaroxConfig',的{{1}}类配置中包含INSTALLED_APPS，一切正常。

你有什么主意吗？
