pycharm+django搭建简单blog
0 工程环境
- windows8.1
- python2.7.8
- django1.5
1 创建项目
方法一：命令行创建
django-admin.py startproject myweb方法二：用pycharm这个IDE来创建
工程目录：
这里pycharm会自动创建模板目录tmplates，并且在settings.py文件中加入这个模板的相对路径，可以手动添加这个目录
在settings里面修改时区为Asia/Shanghai 语言为zh-cn
命令行
manage.py runserver 80 Validating models... 0 errors found December 28, 2014 - 14:24:38 Django version 1.5.11, using settings 'myweb.settings' Development server is running at http://127.0.0.1:8000/ Quit the server with CTRL-BREAK.也可以直接在pycharm里面点击运行，IDE自带的控制台与此显示相同，点击停止就停止服务器
2 创建应用
python manage.py startapp blog
前面的python关键字可省
目录结构：
打开blog目录下的models.py
from django.db import models
# Create your models here.
class BlogsPost(models.Model):
title=models.CharField(max_length=150)
body=models.TextField()
timestamp=models.DateTimeField()创建BlogsPost类，继承django.db.models.Model父类，定义三个变量，title （博客标题），body（博客正文），timestamp（博客创建时间）
在settings 的APP选项里面加入blog
3 设置数据库
这里用sqlite3，简单小巧，设置settings文件数据库选项 'ENGINE': 'django.db.backends.sqlite3' 'NAME': 'mydb' 其他项对于sqlite3来说不用填
运行命令创建数据库：
D:\codetest\myweb>python manage.py sql blog
BEGIN;
CREATE TABLE "blog_blogspost" (
"id" integer NOT NULL PRIMARY KEY,
"title" varchar(150) NOT NULL,
"body" text NOT NULL,
"timestamp" datetime NOT NULL
)
;
COMMIT;
可以看到自动添加了主键id
运行命令行同步：
D:\codetest\myweb>python manage.py syncdb Creating tables ... Creating table auth_permission Creating table auth_group_permissions Creating table auth_group Creating table auth_user_groups Creating table auth_user_user_permissions Creating table auth_user Creating table django_content_type Creating table django_session Creating table django_site Creating table django_admin_log Creating table blog_blogspost You just installed Django's auth system, which means you don't have any superusers defined. Would you like to create one now? (yes/no): yes Username (leave blank to use 'tashaxing'): Email address: Password: Password (again): Superuser created successfully. Installing custom SQL ... Installing indexes ... Installed 0 object(s) from 0 fixture(s)邮箱可不填，用户名不填则默认是系统名
4 设置admin
注意在主站点目录的urls.py中将admin的那行解注释
# Uncomment the next line to enable the admin:
url(r'^admin/', include(admin.site.urls)),
并且在settings文件里的APP选项中解注释admin
# Uncomment the next line to enable the admin:
'django.contrib.admin',
from django.db import models
from django.contrib import admin
# Create your models here.
class BlogsPost(models.Model):
title=models.CharField(max_length=150)
body=models.TextField()
timestamp=models.DateTimeField()
admin.site.register(BlogsPost)官方文档中的方法是在blog目录下新建admin.py然后在里面注册，这里简化了这个步骤，直接写道models.py
修改了models.py之后要同步一下
python manage.py syncdb启动服务器，在浏览器中输入127.0.0.1/admin，进入管理页面
添加博客
from django.db import models
from django.contrib import admin
# Create your models here.
class BlogsPost(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(BlogsPost,BlogPostAdmin)
修改后
5 创建template,view,URL
下面的内容就是创建blog的公共部分，模板，视图，url
在templates目录下创建archive.html
{% for post in posts %}
<h2>{{ post.title }}</h2>
<p>{{ post.timestamp }}</p>
<p>{{ post.body }}</p>
{% endfor%}
创建视图views，打开blog目录下的views.py
from django.shortcuts import render
from django.template import loader,Context
from django.http import HttpResponse
from blog.models import BlogsPost
# Create your views here.
def archive(request):
posts=BlogsPost.objects.all()
t=loader.get_template('archive.html')
c=Context({'posts':posts})
return HttpResponse(t.render(c))
from django.conf.urls import patterns, include, url
# Uncomment the next two lines to enable the admin:
from django.contrib import admin
admin.autodiscover()
urlpatterns = patterns('',
# Examples:
# url(r'^$', 'myweb.views.home', name='home'),
# url(r'^myweb/', include('myweb.foo.urls')),
url(r'^blog/',include('blog.urls')),
# Uncomment the admin/doc line below to enable admin documentation:
url(r'^admin/doc/', include('django.contrib.admindocs.urls')),
# Uncomment the next line to enable the admin:
url(r'^admin/', include(admin.site.urls)),
)
在blog目录下创建urls.py文件，*号表示导入了很多模块比如：patterns, include, url
from django.conf.urls import *
from blog.views import archive
urlpatterns=patterns('',
url(r'^$',archive),
)
6 添加样式
templates目下添加主模板base.html
<!DOCTYPE html>
<html>
<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>
<body>
<h1>踏莎行blog</h1>
<h3>疏影横斜水清浅，暗香浮动月黄昏</h3>
{% block content %}
{% endblock %}
</body>
</html>
在archive.html中继承
<!DOCTYPE html>
<html>
<body>
{% extends "base.html" %}
{% block content %}
{% for post in posts %}
<h2>{{ post.title }}</h2>
<p>{{ post.timestamp }}</p>
<p>{{ post.body }}</p>
{% endfor %}
{% endblock %}
</body>
</html>更新博客页面
但是这样不是很爽，如果变成目录页和具体博客页两级网页多好。下面具体实现。
7 增加页面
views修改
from django.shortcuts import render
from django.template import loader,Context
from django.http import HttpResponse
from blog.models import BlogsPost
# Create your views here.
def index(request):
posts=BlogsPost.objects.all()
t=loader.get_template('bloglist.html')
c=Context({'posts':posts})
return HttpResponse(t.render(c))
def archive(request,blog_id):
p=BlogsPost.objects.get(pk=blog_id)
t=loader.get_template('archive.html')
c=Context({'p':p})
return HttpResponse(t.render(c))
blog/urls.py修改
from django.conf.urls import *
from blog.views import index,archive
urlpatterns=patterns('',
url(r'^$',index),
url(r'^(?P<blog_id>\d+)/$',archive)
)
<!DOCTYPE html>
<html>
{% extends "base.html" %}
{% block content %}
{% for post in posts %}
<h2><a href="/blog/{{ post.id }}" style="color:#00f0ff">{{ post.title }}</a></h2>
{% endfor %}
{% endblock %}
<body>
</body>
</html>
<!DOCTYPE html>
<html>
<body>
{% extends "base.html" %}
{% block content %}
<h2>{{ p.title }}</h2>
<p>{{ p.timestamp }}</p>
<p>{{ p.body }}</p>
{% endblock %}
</body>
</html>
这样，输入127.0.0.1/blog会进入目录页，点具体目录链接接到具体文章页，如：127.0.0.1/blog/2
后面还可以加主页，404页，加各种酷炫的css样式表，哈哈

ps：吐槽一下csdn的上传gif功能，必须在批量传图的地方传gif才有效，而且要勾上无水印，用编辑区的工具传图gif不动！！
