小编Sin*_*ama的帖子

我已经在Django中学到了一些基础知识,但我坚持使用本教程:

http://docs.djangoproject.com/en/dev/intro/tutorial02/#customize-the-admin-change-list

was_published_today添加时发现错误:

global name 'datetime' is not defined

一些搜索结果建议我导入datetime模块,但我不知道如何做到这一点.

from django.db import datetime在polls/admin.py或polls/models.py似乎无用

这是settings.py:

# Django settings for kaka project.

DEBUG = True
TEMPLATE_DEBUG = DEBUG

ADMINS = (
    # ('Your Name', 'your_email@domain.com'),
)

MANAGERS = ADMINS

DATABASE_ENGINE = 'mysql'           # 'postgresql_psycopg2', 'postgresql', 'mysql', 'sqlite3' or 'oracle'.
DATABASE_NAME = 'kaka'             # Or path to database file if using sqlite3.
DATABASE_USER = 'root'             # Not used with sqlite3.
DATABASE_PASSWORD = 'z'         # …

我对Java一无所知.

有Java 6 steady state基准

这Java 6 steady state是所有其他Java中最快的.我搜索过,没有好结果

什么是Java 6 steady state？可以运行任何Java Web框架Java 6 steady state吗？
