本节介绍 Form 中一些字段类型的使用，以文件上传字段 FileField 为例：（注，其它字段和相关用法见官方文档中的 Forms -> Built-in Fields）
一，配置 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/$', 'blog.views.show_author'), url(r'blog/register/$', 'blog.views.register'), # Django Form url(r'blog/regist/$', 'blog.views.regist'), # 在前面例子的基础上增加 127.0.0.1:8000/blog/regist/ 地址作测试 )
二，编写 blog.views.regist 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}) from django import forms from django.http import HttpResponse class UserForm(forms.Form): name = forms.CharField() # username = forms.CharField() headImg = forms.FileField() def register(req): if req.method == 'POST': form = UserForm(req.POST) # Binding if form.is_valid(): print form.cleaned_data return HttpResponse('ok') else: form = UserForm() return r2r('register.html', {'form':form}) def regist(req): if req.method == 'POST': uf = UserForm(req.POST, req.FILES) # 绑定 if uf.is_valid(): print uf.cleaned_data['name'] upfile = uf.cleaned_data['headImg'] print upfile.name, upfile.size fp = file('upload/'+upfile.name, 'wb') fp.write(upfile.read()) fp.close() return HttpResponse('OK') else: uf = UserForm() return r2r('regist.html', {'uf':uf})
三，编写模板文件 blog/templates/regist.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> <div>User Regist</div> <div> <form method='post' enctype="multipart/form-data"> {{uf.as_p}} <input type='submit' value='ok' /> </form> </div> </body> </html>
