基于Aptana3+Django开发blog的示例

http://my.oschina.net/u/1412027/blog/197781

1、建立一个Django Project





2、配置IDE的环境













3、选择django的版本号，先查看当前系统中的django版本号（IDE默认选择1.2 or later）





这里默认使用sqlite，先使用默认的进行处理（有兴趣的可以改为mysql试试）





默认生成的4个文件：





先跑起来看一下效果：





注意选择Debug Configurations，选择要运行的项目和主模块（选择项目根目录下的manage.py即可）





默认监听的是8000，这里修改为9000









控制台上的信息：

pydev debugger: starting





4、修改配置文件settings.py

找到TIME_ZONE，修改为TIME_ZONE = 'Asia/Shanghai'

找到LANGUAGE_CODE修改为LANGUAGE_CODE = 'zh-CN'

# Django settings for demo project.

DEBUG = True
TEMPLATE_DEBUG = DEBUG

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

MANAGERS = ADMINS

DATABASES = {
'default': {
'ENGINE': 'django.db.backends.sqlite3',  # Add 'postgresql_psycopg2', 'postgresql', 'mysql', 'sqlite3' or 'oracle'.
'NAME': 'XXXXXXXXXXXXXXXXXX',  # Or path to database file if using sqlite3.
'USER': 'XXXXXXXXX',  # Not used with sqlite3.
'PASSWORD': 'XXXXXXXX',  # Not used with sqlite3.
'HOST': '',  # Set to empty string for localhost. Not used with sqlite3.
'PORT': '',  # Set to empty string for default. Not used with sqlite3.
}
}

# Local time zone for this installation. Choices can be found here:
# http://en.wikipedia.org/wiki/List_of_tz_zones_by_name # although not all choices may be available on all operating systems.
# On Unix systems, a value of None will cause Django to use the same
# timezone as the operating system.
# If running in a Windows environment this must be set to the same as your
# system time zone.
TIME_ZONE = 'Asia/Shanghai'

# Language code for this installation. All choices can be found here:
# http://www.i18nguy.com/unicode/language-identifiers.html LANGUAGE_CODE = 'zh-CN'
SITE_ID = 1

# If you set this to False, Django will make some optimizations so as not
# to load the internationalization machinery.
USE_I18N = True

# If you set this to False, Django will not format dates, numbers and
# calendars according to the current locale
USE_L10N = True

# Absolute filesystem path to the directory that will hold user-uploaded files.
# Example: "/home/media/media.lawrence.com/media/"
MEDIA_ROOT = ''

# URL that handles the media served from MEDIA_ROOT. Make sure to use a
# trailing slash.
# Examples: "http://media.lawrence.com/media/", "http://example.com/media/"
MEDIA_URL = ''

# Absolute path to the directory static files should be collected to.
# Don't put anything in this directory yourself; store your static files
# in apps' "static/" subdirectories and in STATICFILES_DIRS.
# Example: "/home/media/media.lawrence.com/static/"
STATIC_ROOT = ''

# URL prefix for static files.
# Example: "http://media.lawrence.com/static/"
STATIC_URL = '/static/'

# URL prefix for admin static files -- CSS, JavaScript and images.
# Make sure to use a trailing slash.
# Examples: "http://foo.com/static/admin/", "/static/admin/".
ADMIN_MEDIA_PREFIX = '/static/admin/'

# Additional locations of static files
STATICFILES_DIRS = (
# Put strings here, like "/home/html/static" or "C:/www/django/static".
# Always use forward slashes, even on Windows.
# Don't forget to use absolute paths, not relative paths.
)

# List of finder classes that know how to find static files in
# various locations.
STATICFILES_FINDERS = (
'django.contrib.staticfiles.finders.FileSystemFinder',
'django.contrib.staticfiles.finders.AppDirectoriesFinder',
#    'django.contrib.staticfiles.finders.DefaultStorageFinder',
)

# Make this unique, and don't share it with anybody.
SECRET_KEY = 'e1=wpjck+9x5tppagmj78m!lep%h+g4z))$%=f&cl)_qihn(c!'

# List of callables that know how to import templates from various sources.
TEMPLATE_LOADERS = (
'django.template.loaders.filesystem.Loader',
'django.template.loaders.app_directories.Loader',
#     'django.template.loaders.eggs.Loader',
)

MIDDLEWARE_CLASSES = (
'django.middleware.common.CommonMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
)

ROOT_URLCONF = 'demo.urls'

TEMPLATE_DIRS = (
# Put strings here, like "/home/html/django_templates" or "C:/www/django/templates".
# Always use forward slashes, even on Windows.
# Don't forget to use absolute paths, not relative paths.
)

INSTALLED_APPS = (
'django.contrib.auth',
'django.contrib.admin',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.sites',
'django.contrib.messages',
'django.contrib.staticfiles',
'demo.blog',
# Uncomment the next line to enable the admin:
# 'django.contrib.admin',
# Uncomment the next line to enable admin documentation:
# 'django.contrib.admindocs',
)

# A sample logging configuration. The only tangible logging
# performed by this configuration is to send an email to
# the site admins on every HTTP 500 error.
# See http://docs.djangoproject.com/en/dev/topics/logging for
# more details on how to customize your logging configuration.
LOGGING = {
'version': 1,
'disable_existing_loggers': False,
'handlers': {
'mail_admins': {
'level': 'ERROR',
'class': 'django.utils.log.AdminEmailHandler'
}
},
'loggers': {
'django.request': {
'handlers': ['mail_admins'],
'level': 'ERROR',
'propagate': True,
},
}
}

5、建立一个blog app应用(也可以在项目的windows中的目录使用命令，效果是一样)









6、修改settings.py，添加对blog的引用

找到INSTALLED_APPS，在尾部添加一行“demo.blog”（项目为demo、应用为blog）

INSTALLED_APPS = (

'django.contrib.auth',

'django.contrib.contenttypes',

'django.contrib.sessions',

'django.contrib.sites',

'demo.blog',

)

7、打开blog/models.py，添加一个文章类：

from django.db import models
from django.contrib import admin

# Create your models here.
class BlogPost(models.Model):
title = models.CharField(max_length=150)
body = models.TextField()
timestamp = models.DateTimeField()

class BlogPostAdmin(admin.ModelAdmin):
list_display = ('title', 'timestamp')

admin.site.register(BlogPost, BlogPostAdmin)

8、右击项目，执行sync DB，在控制台上可看到如下信息













9、修改settings.py，添加admin app

找到INSTALLED_APPS，在django.contrib.auth下一行添加'django.contrib.admin',

INSTALLED_APPS = (

'django.contrib.auth',

'django.contrib.admin',

'django.contrib.contenttypes',

'django.contrib.sessions',

'django.contrib.sites',

'demo.blog',

)

修改数据库的连接(工程根目录下的settings.py)：





再执行一个sync DB





10、修改项目根目录下的urls.py，去掉urlpatterns中最后一项对admin的注释

(r'^admin/', include(admin.site.urls)),

---将最前面的“#”去掉即可，需要引入包“from django.contrib import admin” 在admin后面按下alt+/就可以自动导入包了

在blog/models.py中，添加一行

admin.site.register(BlogPost)

查看一下项目运行的效果：









添加两条数据后的效果显示，有一些难看，待会进行修改





在blog/models.py添加一个ModelAdmin类

from django.db import models
from django.contrib import admin

# Create your models here.
class BlogPost(models.Model):
title = models.CharField(max_length=150)
body = models.TextField()
timestamp = models.DateTimeField()

class BlogPostAdmin(admin.ModelAdmin):
list_display = ('title', 'timestamp')

admin.site.register(BlogPost, BlogPostAdmin)

刷新页面，就变成下面这样子了





11、使用模板，显示添加的数据

在blog目录下建立一个名为templates的目录，在此目录下建立一个名为archive.html(demo/blog/templates/archive.html)，输入如下内容：

{% for post in posts %}
{{ post.title }}
{{ post.timestamp }}
{{ post.body }}
{% endfor %}

12、打开blog的views.py，添加对视图的控制

# Create your views here.
from django.template import loader, Context
from django.http import HttpResponse
from demo.blog.models import BlogPost

def archive(request):
posts = BlogPost.objects.all().order_by("-timestamp")
t = loader.get_template("archive.html")
c = Context({ 'posts': posts })
return HttpResponse(t.render(c))

13、在主urls.py中添加对blog的url匹配，在最后一行添加(r'^blog/',
include('demo.blog.urls')),

from django.conf.urls.defaults import patterns, include
# Uncomment the next two lines to enable the admin:
from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
# Examples:
# url(r'^$', 'demo.views.home', name='home'),
# url(r'^demo/', include('demo.foo.urls')),

# Uncomment the admin/doc line below to enable admin documentation:
# url(r'^admin/doc/', include('django.contrib.admindocs.urls')),

# Uncomment the next line to enable the admin:
#      url(r'^admin/', include(admin.site.urls)),
#      (r'^blog/', include('demo.blog.urls')),
(r'^admin/', include(admin.site.urls)),
(r'^blog/', include('demo.blog.urls')),
)

14、在blog中新建立一个urls.py文件，添加如下内容

from django.conf.urls.defaults import *
from demo.blog.views import archive

urlpatterns = patterns('',
url(r'^$', archive),
)

现在的运行效果：





这个页面有两个问题：

1、没有按发表的时间降序排列文章

2、界面太简单，需要修饰一下

改进：

在blog/templates目录下建立一个名为base.html的页面

<html>
<head>
<style type="text/css">
body {
color: #efd;
background: #453;
padding: 0 5em;
margin: 0
}

h1 {
padding: 2em 1em;
background: #675
}

h2 {
color: #bf8;
border-top: 1px dotted #fff;
margin-top: 2em
}

p {
margin: 1em 0
}
</style>
</head>
<body>
<h1>markGao's BLOG</h1>
{%block content%} {%endblock%}
</body>
</html>

修改archive.html页面

{% extends "base.html" %} {% block content %} {% for post in posts %}
<h2>{{ post.title }}</h2>
<p>{{ post.timestamp|date:"l, F jS" }}</p>
<p>{{ post.body }}</p>
{% endfor %} {% endblock %}

现在的界面漂亮一些了





修改<p>{{ post.timestamp }}</p>为<p>{{ post.timestamp|date:"l, F jS" }}</p>

在blog/views.py中，将文章按时间降序排列（加一个”-”，不加则为升序，还可以添加按标题排序等）

posts = BlogPost.objects.all().order_by("-timestamp")
