Django中Forms的使用代码解析_Python

本文研究的主要是Django中Forms的使用，具体如下。

创建文件do.html

									{% extends 'base.html' %} 

									{% block mainbody %} 

									  <form action="/app1/do/" method="post"> 

									    {% csrf_token %} 

									    {{ form.as_p }} 

									    <input type="submit" value="Submit"> 

									  </form> 

									{% for item in student %} 

									  <p>{{ item.id }}, {{ item }}</p> 

									{% endfor %} 

									{% endblock %}

在urls.py中添加路径：

url(r'^do/', 'app1.views.do'),

在views.py中定义do函数

									from django.shortcuts import render 

									from django.core.context_processors import csrf 

									from app1.models import Student 

									from django import forms 

									def do(request): 

									  context = {} 

									  context.update(csrf(request)) 

									  if request.POST: 

									    form = StudnetForm(request.POST) 

									    if form.is_valid(): 

									      name = form.cleaned_data['name'] 

									      student = Student(name = name) 

									      student.save() 

									  form = StudnetForm() 

									  context = {} 

									  context.update(csrf(request)) 

									  student_list = Student.objects.all() 

									  context['student'] = student_list 

									  context['form'] = form  

									  return render(request, 'do.html', context)
