djang里的url.py在我们的项目里使用来控制进入站点的流向，所有进入的urls将会与urlpatterns里配置的正则表达式匹配。
开始：设计app （Designing a pastebin app）
Some ‘views’ that the user will see are（html展示）
- A list view of all recent texts （列出最近的文本）
- A detail view of any selected text （每个文本的详细信息）
- An entry/edit form for a text （编辑文本界面）
- A view to delete a text （删除界面）
我们将会用到的generic View
django.views.generic.DetailView
(用来显示每个文本的详细信息)
django.views.generic.ListView
（用来显示文本的列表，全部文本）
django.views.generic.DeleteView
（删除）
django.views.generic.UpdateView
（更改、编辑）
创建一个应用
django-admin manage.py startproject pastebin
（创建项目 ）
django-admin manage.py startapp app02
（创建 app02 应用） In pastebin/models.py from django.db import models # Create your models here. class Paste(models.Model): text = models.TextField() name = models.CharField(max_length=40, null=True, blank=True) created_on = models.DateTimeField(auto_now_add=True) updated_on = models.DateTimeField(auto_now=True) def __unicode__(self): return self.name or str(self.id)
auto_now_add 把当前时间给 created_on字段，并且每次提交后不可更改。
auto_now 与 auto_now_add 类似，但是每次更改完文本再次提交后会改变，显示当前提交的时间。
id 是默认创建的主键
Adding our app to the projectINSTALLED_APPS = ( ‘django.contrib.admin‘, ‘django.contrib.auth‘, ‘django.contrib.contenttypes‘, ‘django.contrib.sessions‘, ‘django.contrib.messages‘, ‘django.contrib.staticfiles‘, #‘app01‘, ‘app02‘, )数据库的配置
DATABASES = { ‘default‘: { ‘ENGINE‘: ‘django.db.backends.sqlite3‘, ‘NAME‘: os.path.join(BASE_DIR, ‘db.sqlite3‘), } }
同步数据库
django-admin manage.py makemigrationsdjango-admin manage.py mirgate
配置app02/urls.py pastebin/urls.py
1、/pastebin/urls.py
from django.conf.urls import patterns, include, url from django.contrib import admin urlpatterns = patterns(‘‘, url(r‘^admin/‘, include(admin.site.urls)), (r‘^pastebin/‘, include(‘app02.urls‘)), )2、app/urls.py
‘‘‘ @author: xaiowei ‘‘‘ from django.views.generic.list import ListView from django.conf.urls import * from app02.models import Paste from django.conf.urls.i18n import urlpatterns from sre_parse import Pattern from django.views.generic import DetailView from django.views.generic.edit import CreateView from django.conf.urls import patterns from gc import get_objects from app02.views import MyDetailView,MyListView,show,MyDeleteView,MyUpdateView urlpatterns = patterns (‘‘, url(r‘^paste/(?P<pk>\d+)/$‘,MyDetailView.as_view(),name=‘pastebin_paste_detail‘), url(r‘^pastes/$‘, MyListView.as_view(),name=‘pastebin_paste_list‘), url(r‘^index/$‘, ‘app02.views.show‘), url(r‘^paste/delete/(?P<pk>\d+)$‘,MyDeleteView.as_view() , name=‘pastebin_paste_delete‘), DetailView读取的是pk或者slug url (r‘^paste/edit/(?P<pk>\d+)$‘, MyUpdateView.as_view(), name=‘pastebin_paste_edit‘), UpdateView读取的也是pk或者slug url(r‘^$‘,CreateView.as_view(model=Paste)), )
配置模板

djang1.7 复制粘贴小项目（generic View的使用）
