'ascii' codec can't encode characters in position 0-4: ordinal not in range(128)

安装好django suit后，运行服务器：
python manage.py runserver

在表单页面输入中文，保存时，出现如下错误：
UnicodeEncodeError at /admin/ModelApp/server/1/change/
'ascii' codec can't encode characters in position 0-4: ordinal not in range(128)
Request Method: POST
Request URL: http://127.0.0.1:8000/admin/ModelApp/server/1/change/
Django Version: 1.11.5
Exception Type: UnicodeEncodeError
Exception Value:
'ascii' codec can't encode characters in position 0-4: ordinal not in range(128)

解决方法：
在manage.py头部加入如下代码:
import sys
reload(sys)
sys.setdefaultencoding('utf8')


如：

# -*- coding: utf-8 -*-

 #!/usr/bin/env python

 import os

 import sys

 reload(sys)

 sys.setdefaultencoding('utf8')



 if __name__ == "__main__":

     os.environ.setdefault("DJANGO_SETTINGS_MODULE", "GM_yaowentan.settings")

     try:

         from django.core.management import execute_from_command_line

     except ImportError:

         # The above import may fail for some other reason. Ensure that the

         # issue is really that Django is missing to avoid masking other

         # exceptions on Python 2.

         try:

             import django

         except ImportError:

             raise ImportError(

                 "Couldn't import Django. Are you sure it's installed and "

                 "available on your PYTHONPATH environment variable? Did you "

                 "forget to activate a virtual environment?"

             )

         raise
    execute_from_command_line(sys.argv)
