Django SYNCDB failes when adding super-user (Windows 7, mySQL, Django 1.2.4, mySQL 5.5)

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.
