eclipse创建一个django及管理界面排版和多语言实现

1.  新建project及app：

            New-Other-Pydev Django project  -- 'django-utils'

            New-Django-Create Application --  'book'

   2.修改models.py和settings.py

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 __unicode__(self):
        return self.name
    

    class Meta:
        ordering = ['name']
        db_table = 'kt_publisher'

    在settings.py 的INSTALLED_APPS 元组中添加新建的App--‘book',修改数据库配置，首先在对应数据库中新建数据库。

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',  # Add 'postgresql_psycopg2', 'mysql', 'sqlite3' or 'oracle'.
        'NAME': 'book',  # Or path to database file if using sqlite3.
        # The following settings are not used with sqlite3:
        'USER': 'root',
        'PASSWORD': '',
        'HOST': '',  # Empty for localhost through domain sockets or '127.0.0.1' for localhost through TCP.
        'PORT': '',  # Set to empty string for default.
    }
}

     数据库book是事先在mysql中建立的，django同步必须为已经存在的数据库才行。

    3.同步数据库

          django-sync DB(syncdb manage.py )

          同步成功后，可以在浏览器中访问了，http://192.168.0.1:8000/admin/

    4.管理自定义app

          django的后台管理界面默认现实为2个app--Groups  Users,如果想现实自定义的app如book，按如下配置：book-admin.py 

# django imports
from django.contrib import admin
from django import forms
from django.utils.translation import ugettext_lazy as _
from book.models import Publisher
class PublisherAdmin(admin.ModelAdmin):
    list_display = ('name', 'address', 'website')#列表现实字段
    search_fields = ('name',)#列表上面搜索框，搜索字段 （like匹配）
    list_filter = ('country',)#列表过滤字段
    fieldsets = (#详细界面，分类现实详细字段
        ('info', {'fields': ('name',)}),
        ('location',{'fields':('country','state_province','city','address')}),
        ('site',{'fields':('website',)})
    )
    
admin.site.register(Publisher, PublisherAdmin)#把上面配置注册到管理界面

    5.实现多语言

    在setting.py中添加设置：

    MIDDLEWARE_CLASSES增加'django.middleware.locale.LocaleMiddleware'，该中间要出现在SessionMiddleware和CacheMiddleware后，其他所有中件间之前

    TEMPLATE_CONTEXT_PROCESSORS 增加 'django.core.context_processors.i18n'

     在app下新建文件夹locale/zh_CN(对应不同语言)/LG_MESSAGES/    新建文件django.po，内容如下：

# SOME DESCRIPTIVE TITLE.

# This file is distributed under the same license as the PACKAGE package.

msgid "We're sorry, but the requested page could not be found."
msgstr "很抱歉，您所请求的页面未找到。"

msgstr "主页"

msgstr "服务器错误（500）"

#: templates/500.html:9
msgid "Server Error <em>(500)</em>"
msgstr "服务器错误 <em>(500)</em>"

#: templates/500.html:10
msgid ""
"There's been an error. It's been reported to the site administrators via e-"
"mail and should be fixed shortly. Thanks for your patience."
msgstr "系统发生错误。改错误已经通过邮件发给管理员处理。"

#: templates/admin/base_site.html:4
msgid "Site Admin"
msgstr "站点管理"

msgid "Change language"
msgstr "语言"

msgstr "简体中文"

msgid "Traditional Chinese"
msgstr "繁体中文"

msgid "Ignore"
msgstr "忽略"

#: settings.py:36

msgid "Year"
msgstr "年"

#: settings.py:92
msgid "Month"
msgstr "月"

#: settings.py:93
msgid "Day"
msgstr "日"

    在terminal（终端）cd 到LG_MESSAGES目录下，运行命令：msgfmt django.po -o django.mo

    重启服务就会发现英文已经有所翻译，但是想要翻译制定的字段还要在django.po文件中配置，然后到目录下运行上面命令。
