在django框架之外使用django模型 [英] using django model outside of the django framework

问题描述

我有一个django应用程序正常工作。我想要能够利用该模型从另一个（独立的）python应用程序访问数据库。这是我有的（这不行）。

  import sys 
 import os 
 
 sys.path.append（os.path.abspath（/ home / pi / garageMonitor / django / garageMonitor））
 os.environ ['DJANGO_SETTINGS_MODULE'] ='garageMonitor.settings'
导入模型
 config = models.SystemConfiguration.objects.filter（idSystemConfiguration = 1）
 config = config [0] 
 for x in config .__ dict__：
 print x 
  

这是我得到的错误：

 文件/home/pi/garageMonitor/django/lib/webWatcher.py，第14行在< module> 
导入模型
文件/home/pi/garageMonitor/django/garageMonitor/models.py，第11行在< module> 
 class DoorClosing（models.Model）：
文件/usr/local/lib/python2.7/dist-packages/django/db/models/base.py，第131行，__new__ 
'app''％（new_class .__ name__，model_module .__ name__）
 django.core.exceptions.ImproperlyConfigured：无法检测模型DoorClosing 
  

DoorClosing是我的models.py文件中的一个类，类似的代码在django框架内工作，我缺少什么？

解决方案

运行

  django.setup（）$ b $在导入模型之前，b  

  import django 
 import sys 
 import os 
 
 sys.path.append（os.path.abspath（/ home / pi / garageMonitor / django / garageMonitor ）
 os.environ ['DJANGO_SETTINGS_MODULE'] ='garageMonitor.settings'
 django.setup（）
导入模型
 config = models.SystemConfiguration.objects.filter（idSystemConfiguration = 1）
 confi g = config [0] 
在配置中的x。_ dict_：
 print x

I have a django application that is working fine. I want to be able to leverage the model to access the database from another (standalone) python app. Here is what I have (that doesn't work.)

import sys
import os

sys.path.append(os.path.abspath("/home/pi/garageMonitor/django/garageMonitor"))
os.environ['DJANGO_SETTINGS_MODULE'] = 'garageMonitor.settings'
import models
    config = models.SystemConfiguration.objects.filter(idSystemConfiguration=1)
    config = config[0]
    for x in config.__dict__:
      print x

Here is the error I get:

  File "/home/pi/garageMonitor/django/lib/webWatcher.py", line 14, in <module>
    import models
  File "/home/pi/garageMonitor/django/garageMonitor/models.py", line 11, in <module>
    class DoorClosing(models.Model):
  File "/usr/local/lib/python2.7/dist-packages/django/db/models/base.py", line 131, in __new__
    'app.' % (new_class.__name__, model_module.__name__)
django.core.exceptions.ImproperlyConfigured: Unable to detect the app label for model "DoorClosing

DoorClosing is a class in my models.py file. Similar code works within the django framework. What am I missing?

解决方案

run

django.setup()

before importing your models

import django
import sys
import os

sys.path.append(os.path.abspath("/home/pi/garageMonitor/django/garageMonitor"))
os.environ['DJANGO_SETTINGS_MODULE'] = 'garageMonitor.settings'
django.setup()
import models
    config = models.SystemConfiguration.objects.filter(idSystemConfiguration=1)
    config = config[0]
    for x in config.__dict__:
      print x
