syncdb fails when creating super user
Django: v 1.2.4 Python: 2.6 MySQL Server: 5.5 Windows 7 Extra: MySQL-Python v1.2.3
What steps will reproduce the problem? 1. install the above programs 2. create a project 3. run syncdb
Note: I have installed mySQL to support UTF 8. I also create the mysite_db database using CREATE DTABASE mysite_db CHARACTER SET = UTF8;
What is the expected output? What do you see instead?
syncdb create the required tables as follows:
C:\DjangoProjects\mysite>python manage.py syncdb
Creating table auth_permission开发者_运维问答
Creating table auth_group_permissions
Creating table auth_group
Creating table auth_user_user_permissions
Creating table auth_user_groups
Creating table auth_user
Creating table auth_message
Creating table django_content_type
Creating table django_session
Creating table django_site
You just installed Django's auth system, which means you don't have any superuse
rs defined.
Would you like to create one now? (yes/no):
I select 'YES' and get the following error:

What version of the product are you using? On what operating system?
Django: v 1.2.4 Python: 2.6 MySQL Server: 5.5 Windows 7 Extra: MySQL-Python v1.2.3
Please provide any additional information below.
I also have mySQL C++ and ODBC database connectors installed. Any help is greatly appreciated.
Looks like you have unicode characters somewhere in your models.py or a fixture. Convert the files to UTF-8 and add a comment as the very first line:
#coding-utf-8
Also, before unicode strings add u
, like this:
name = CharField(maxlength=255, default=u"утф-8 строка");
It looks like your login on your development machine has a unicode character in it, and when the createsuperuser.py
module looks for a User
object with that username, it is barfing because MySQL isn't expecting those characters. You can either change the collation settings on your MySQL tables to accept UTF-8 or use a username that doesn't have unicode characters (which isn't a very nice option).
The real failure in the traceback starts in createsuperuser.py
on line 71, and it stems from line 59 here:
try:
default_username = getpass.getuser().replace(' ', '').lower()
except (ImportError, KeyError):
# KeyError will be raised by os.getpwuid() (called by getuser())
# if there is no corresponding entry in the /etc/passwd file
# (a very restricted chroot environment, for example).
default_username = ''
# Determine whether the default username is taken, so we don't display
# it as an option.
if default_username:
try:
User.objects.get(username=default_username)
except User.DoesNotExist:
pass
else:
default_username = ''
It's getting your username via getpass
and then trying to look that up in the User
table.
