PyCharm中運行django程序

使用PyCharm開發django程序，發現如果不在命令行而在IDE的django項目中直接運行django程序，發現報錯，程序如下：

def main():
    from people.models import Blog
    blog = Blog()
    blog.name = 'blog1'
    blog.tagline = 'tagline1'
    blog.save()

if __name__ == '__main__':
    main()
    print('Done......')

拋出的異常如下：

C:\python\python.exe C:/Users/Administrator/PycharmProjects/mydjango/mytest.py
Traceback (most recent call last):
  File "C:/Users/Administrator/PycharmProjects/mydjango/mytest.py", line 10, in <module>
    main()
  File "C:/Users/Administrator/PycharmProjects/mydjango/mytest.py", line 3, in main
    from people.models import Blog
  File "C:\Users\Administrator\PycharmProjects\mydjango\people\models.py", line 4, in <module>
    class Person(models.Model):
  File "C:\Users\Administrator\PycharmProjects\mydjango\people\models.py", line 5, in Person
    name = models.CharField(max_length=30)
  File "C:\python\lib\site-packages\django-1.10-py3.5.egg\django\db\models\fields\__init__.py", line 1043, in __init__
    super(CharField, self).__init__(*args, **kwargs)
  File "C:\python\lib\site-packages\django-1.10-py3.5.egg\django\db\models\fields\__init__.py", line 166, in __init__
    self.db_tablespace = db_tablespace or settings.DEFAULT_INDEX_TABLESPACE
  File "C:\python\lib\site-packages\django-1.10-py3.5.egg\django\conf\__init__.py", line 53, in __getattr__
    self._setup(name)
  File "C:\python\lib\site-packages\django-1.10-py3.5.egg\django\conf\__init__.py", line 39, in _setup
    % (desc, ENVIRONMENT_VARIABLE))
django.core.exceptions.ImproperlyConfigured: Requested setting DEFAULT_INDEX_TABLESPACE, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

Process finished with exit code 1

經上網查找，增加代碼處理如下：

import os
import django

os.environ.setdefault('DJANGO_SETTING_MODULE', 'mydjango.settings')
django.setup()
'''
version = django.get_version()
print(version)
version = (int(version[0]), int(version[2:]))
print(version)

if version >= (1,7):
    django.setup()
'''
def main():
    from people.models import Blog
    blog = Blog()
    blog.name = 'blog1'
    blog.tagline = 'tagline1'
    blog.save()

if __name__ == '__main__':
    main()
    print('Done......')

運行後發現還是異常，此時是LOGGING_CONFIG沒有設置：

C:\python\python.exe C:/Users/Administrator/PycharmProjects/mydjango/mytest.py
Traceback (most recent call last):
  File "C:/Users/Administrator/PycharmProjects/mydjango/mytest.py", line 5, in <module>
    django.setup()
  File "C:\python\lib\site-packages\django-1.10-py3.5.egg\django\__init__.py", line 22, in setup
    configure_logging(settings.LOGGING_CONFIG, settings.LOGGING)
  File "C:\python\lib\site-packages\django-1.10-py3.5.egg\django\conf\__init__.py", line 53, in __getattr__
    self._setup(name)
  File "C:\python\lib\site-packages\django-1.10-py3.5.egg\django\conf\__init__.py", line 39, in _setup
    % (desc, ENVIRONMENT_VARIABLE))
django.core.exceptions.ImproperlyConfigured: Requested setting LOGGING_CONFIG, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

Process finished with exit code 1

經過查找，終於發現將配置添加到pycharm中的python配置中，可以正常運行程序，配置項的key爲DJANGO_SETTINGS_MODULE，value爲django的項目名稱加點號加settings，我的項目名稱爲mydjango，所以value爲mydjango.settings，具體如下圖所示：
