无法在syncdb之后创建超级用户

问题描述

我非常喜欢django和web开发。在创建超级用户时，从Django的最终指南中学习，我收到以下错误（OS mac10.8.2& django1.4.3）

从django的最终指南我正在显示其中一个模型。

  from django.db import models 
 class Publisher（models.Model）： 
 name = models.Cha rField（max_length = 30）
 address = models.CharField（max_length = 50）
 city = models.CharField（max_length = 60）
 state_province = models.CharField（max_length = 30）
 country = models.CharField（max_length = 50）
 website = models.URLField（）
 
 def __str __（self）：
 return self.name 
 
 class Meta：
 order = ['name'] 
  

setting.py数据库设置为： -

  DATABASES = {
'default'：{
'ENGINE'：'django .db.backends.postgresql_psycopg2'，
'NAME'：'books'，
'USER'：'postgres'，
'PASSWORD'：'******' b $ b'HOST'：'localhost'，
'PORT'：'5432'，
} 
} 
  

syncdb运行：

 创建表... 
创建表auth_permission 
创建表auth_group_permissions 
创建表auth_group 
创建表auth_user_user_permissions 
创建表auth_user_groups 
创建表auth_user 
创建表django_content_type 
创建表django_session 
创建表django_site 
创建表books_publisher 
创建表books_author 
创建表books_book_authors 
创建表books_book 
  

是的，创建超级用户我得到错误。

解决方案

看起来你没有正确的本地人安装在您的系统上。

尝试在运行syncdb之前键入以下内容 -

  export LC_CTYPE = en_US.UTF-8 
 export LC_ALL = en_US.UTF-8 
  

（或者你当地应该是什么）。

或者将行添加到您的〜/ .bash_profile

看看

I am quite new to django and web development. Learning from the "Definitive guide to Django" when creating superuser I get the following error (OS mac10.8.2 & django1.4.3)

Would you like to create one now? (yes/no): yes

from the definitive guide to django i am showing one of the models.

from django.db import models
class Publisher(models.Model):
    name = models.CharField(max_length=30)
    address = models.CharField(max_length=50)
    city = models.CharField(max_length=60)
    state_province = models.CharField(max_length=30)
    country = models.CharField(max_length=50)
    website = models.URLField()

    def __str__(self):
        return self.name

    class Meta:
        ordering = ['name']

setting.py database settings are:-

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': 'books',
        'USER': 'postgres',
        'PASSWORD': '******',
        'HOST': 'localhost',
        'PORT': '5432',
    }
}

syncdb runs :

Creating tables ...
Creating table auth_permission
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 django_content_type
Creating table django_session
Creating table django_site
Creating table books_publisher
Creating table books_author
Creating table books_book_authors
Creating table books_book

after yes to create superuser I get the error.

解决方案

It looks like you don't have the right locals installed on your system.

Trying typing the following before running syncdb -

export LC_CTYPE=en_US.UTF-8
export LC_ALL=en_US.UTF-8

(or whatever your local should be).

Alternatively add the lines to your ~/.bash_profile
