PyCharm 在django程序中单独运行py文件

摘要：

使用PyCharm开发django程序。发现如果您在IDE的django项目中直接运行django程序而不使用命令行，则会报告错误。该程序如下：defmain（）：fromPeoples。modelimportBlolog=Blog（）博客。name='blog1'blog。标签=“标签1”日志。save（）if__name__=='__main__'：main（）打印

使用PyCharm开发django程序，发现如果不在命令行而在IDE的django项目中直接运行django程序，发现报错，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......')

抛出异常如下：

C:pythonpython.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

    class Person(models.Model):

    name = models.CharField(max_length=30)

    super(CharField, self).__init__(*args, **kwargs)

    self._setup(name)

    % (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.

经上网查找，增加代码处理如下：

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......')

运行后发现还是异常，此时是LOGGING_CONFIG没有设置：

C:pythonpython.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:pythonlibsite-packagesdjango-1.10-py3.5.eggdjango\__init__.py", line 22, in setup
    configure_logging(settings.LOGGING_CONFIG, settings.LOGGING)
  File "C:pythonlibsite-packagesdjango-1.10-py3.5.eggdjangoconf\__init__.py", line 53, in __getattr__
    self._setup(name)
  File "C:pythonlibsite-packagesdjango-1.10-py3.5.eggdjangoconf\__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

经过查找，终于发现将配置添加到pycharm中的python配置中，可以正常运行程序，配置项的key为DJANGO_SETTINGS_MODULE，value为django的项目名称加点号加settings，我的项目名称为mydjango，所以value为mydjango.settings，具体如下图所示：
