Django中Forms的使用代码解析

yipeiwu_com5年前 (2020-03-06)Python基础

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)

现在的数据库里面有四条数据：
