本讲介绍数据在页面中的呈现，内容很简单，就是嵌套循环在模板中的使用。
一，修改 csvt03/urls.py：
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'^$', 'csvt03.views.home', name='home'), # url(r'^csvt03/', include('csvt03.foo.urls')), # Uncomment the admin/doc line below to enable admin documentation: # url(r'^admin/doc/', include('django.contrib.admindocs.urls')), # Uncomment the next line to enable the admin: url(r'^admin/', include(admin.site.urls)), url(r'^index/$','blog.views.index'), url(r'^blog/show_author/$', 'blog.views.show_author'), )
二，定制视图处理函数 blog/views.py：
from django.shortcuts import render_to_response as r2r from blog.models import Employee, Author, Book def index(req): emps = Employee.objects.all() return r2r('index.html', {'emps':emps}) def show_author(req): authors = Author.objects.all() return r2r('show_author.html', {'authors':authors})
三，定制模板文件 blog/templates/show_author.html：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Django DB</title> </head> <body> {% for author in authors %} <h3>{{author.name}}</h3> <div> {% for book in author.book_set.all %} {{ book }} {% endfor %} </div> {% endfor %} </body> </html>
