在用一个插件生成了类似rails的scaffold，其实无非就是URLconf+MTV。让我们看看具体都生成了哪些东西。

首先是“入口”的定义即URLconf，打开urls.py:

from django.conf.urls.defaults import patterns, include, urlfrom depot.views import hellourlpatterns = patterns('',     url(r'^hello/ hello),)urlpatterns += patterns ('', (r'^depotapp/', include('depotapp.urls')),)

 

上面的代码中增加的配置行表示：以depotapp开头的url由depotapp/urls.py文件进行处理。

django的url配置中，除了（正则表达式，view函数）的方式外，还支持（正则表达式，include文件）的方式。通常把app自身相关的url写到自己的url配置文件中，然后在project中引用。

接下来看一下生成的depotapp/urls.py的内容：

from django.conf.urls.defaults import *from models import *from views import *urlpatterns = patterns('',    (r'product/create/$', create_product),    (r'product/list/$', list_product ),    (r'product/edit/(?P[^/]+)/$', edit_product),    (r'product/view/(?P[^/]+)/$', view_product),)

 

将CRU（没有D)的URL映射到了视图。而视图在depotapp/views.py中定义：

from django import formsfrom django.template import RequestContextfrom django.http import HttpResponse, HttpResponseRedirectfrom django.template.loader import get_templatefrom django.core.paginator import Paginatorfrom django.core.urlresolvers import reverse# app specific filesfrom models import *from forms import *def create_product(request):    form = ProductForm(request.POST or None)    if form.is_valid():        form.save()        form = ProductForm()    t = get_template('depotapp/create_product.html')    c = RequestContext(request,locals())    return HttpResponse(t.render(c))def list_product(request):      list_items = Product.objects.all()    paginator = Paginator(list_items ,10)    try:        page = int(request.GET.get('page', '1'))    except ValueError:        page = 1    try:        list_items = paginator.page(page)    except :        list_items = paginator.page(paginator.num_pages)    t = get_template('depotapp/list_product.html')    c = RequestContext(request,locals())    return HttpResponse(t.render(c))def view_product(request, id):    product_instance = Product.objects.get(id = id)    t=get_template('depotapp/view_product.html')    c=RequestContext(request,locals())    return HttpResponse(t.render(c))def edit_product(request, id):    product_instance = Product.objects.get(id=id)    form = ProductForm(request.POST or None, instance = product_instance)    if form.is_valid():        form.save()    t=get_template('depotapp/edit_product.html')    c=RequestContext(request,locals())    return HttpResponse(t.render(c))

 

视图中的相关内容比较多，主要的是模板，其次还有模型类、Paginator分页器、Form表单等等。

基本涵盖了典型的web应用交互的内容。
