Django的PostgreSQL的連接問題

Question

我在Django

 
>>python manage.py shell 
>>> from django.db import connection 
>>> cursor = connection.cursor() 
Traceback (most recent call last): 
    File "", line 1, in 
    File "/usr/local/lib/python2.6/dist-packages/django/db/backends/__init__.py", line 250, in cursor 
    cursor = self.make_debug_cursor(self._cursor()) 
    File "/usr/local/lib/python2.6/dist-packages/django/db/backends/postgresql_psycopg2/base.py", line 148, in _cursor 
    cursor.execute("SET TIME ZONE %s", [settings_dict['TIME_ZONE']]) 
DataError: unrecognized time zone name: "America/Chicago" 

連接的PostgreSQL有一個問題，但是，當我試圖

 
>>> c=connection.cursor() 
>>> c 

>>> c.execute("select * from test") 
Traceback (most recent call last): 
    File "", line 1, in 
    File "/usr/local/lib/python2.6/dist-packages/django/db/backends/util.py", line 34, in execute 
    return self.cursor.execute(sql, params) 
    File "/usr/local/lib/python2.6/dist-packages/django/db/backends/postgresql_psycopg2/base.py", line 44, in execute 
    return self.cursor.execute(query, args) 
DatabaseError: current transaction is aborted, commands ignored until end of transaction block 

>>> connection.commit() 
Traceback (most recent call last): 
    File "", line 1, in 
    File "/usr/local/lib/python2.6/dist-packages/django/db/backends/__init__.py", line 202, in commit 
    self.set_clean() 
    File "/usr/local/lib/python2.6/dist-packages/django/db/backends/__init__.py", line 147, in set_clean 
    raise TransactionManagementError("This code isn't under transaction management") 
TransactionManagementError: This code isn't under transaction management 
>>> c.execute("select * from test") 
>>> c.fetchone() 
(1, 100, u'abd') 

我不知道問題出在哪裏
我做了谷歌，但它沒有幫助，任何人都可以幫忙嗎？非常感謝。
我的設置是：

 
DATABASES = { 
    'default': { 
     'ENGINE': 'django.db.backends.postgresql_psycopg2', # Add 'postgresql_psycopg2', 'postgresql', 'mysql', 'sqlite3' or 'oracle'. 
     'NAME': 'mydb',      # Or path to database file if using sqlite3. 
     'USER': 'postgres',      # Not used with sqlite3. 
     'PASSWORD': '123',     # Not used with sqlite3. 
     'HOST': '/tmp',      # Set to empty string for localhost. Not used with sqlite3. 
     'PORT': '5432',      # Set to empty string for default. Not used with sqlite3. 
     #'OPTIONS':True, 
    } 
}

樣子時區設置不正確。檢查值「美國/芝加哥」是由你的PostgreSQL配置支持（這是我的工作測試服務器...）

嘗試將其設置爲None - 也許它會幫助你：

TIME_ZONE = None
