Django教程（四）- Django模板及进阶
Django模板及进阶 代码操作：
- home.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>模板实例</title>
</head>
<body>
<!--1.显示一个基本的字符串在网页上-->
<!--{{ string }}-->
<!--2.基本的 for 循环 和 List内容的显示-->
<!--{% for i in list %}-->
<!--{{ i }}-->
<!--{% endfor %}-->
<!--3.显示字典中内容-->
<!--{% for key,value in dict.items %}-->
<!--{{ key }}:{{ value }}-->
<!--{% endfor %}-->
<!--4.在模板进行 条件判断和 for 循环的详细操作：-->
<!--{% for i in list %}-->
<!--{{ i }}{% if not forloop.last %},{% endif %}-->
<!--{% endfor %}-->
<!--#5.模板上得到视图对应的网址：-->
<!--<a href="{% url 'h' 4 5 %}" >友情链接</a>-->
<!--6.模板中的逻辑操作：-->
<!--{% if var >= 90 %}-->
<!--成绩优秀-->
<!--{% elif var >= 80 %}-->
<!--成绩良好-->
<!--{% elif var >= 70 %}-->
<!--成绩一般-->
<!--{% elif var >= 60 %}-->
<!--需要努力-->
<!--{% else %}-->
<!--不及格-->
<!--{% endif %}-->
<!--7.模板中 获取当前网址，当前用户等：-->
<!--{{ request.user }}-->
<!--8.过滤器-->
{{ var|lower }}
</body>
</html>- views.py
# -*- coding: utf-8 -*-
from __future__ import unicode_literals
from django.shortcuts import render,redirect
from temforms import temform
from django.http import HttpResponse
# Create your views here.
# 简单的模板
# def test(request):
# return render(request,'new.html',)
# 1.显示一个基本的字符串在网页上
# def home(request):
# string =u'遇见你真是三生有幸❤'
# return render(request,'home.html',{'string':string})
# 2.基本的 for 循环 和 List内容的显示
# def home(request):
# list =['L','o','v','e','x','l']
# return render(request,'home.html',{'list':list})
# 3.显示字典中内容
# def home(request):
# dict={'name':'中二病控','age':'22','interset':'write'}
# return render(request,'home.html',{'dict':dict})
# 4.在模板进行 条件判断和 for 循环的详细操作：
# def home(request):
# list = map(str,range(20))# 一个长度为10的 List，对range(20)各项进行str操作
# return render(request,'home.html',{'list':list})
#5.模板上得到视图对应的网址：
def add(request,a,b):
c= int(a)+int(b)
return HttpResponse(str(c))
#6.模板中的逻辑操作：
# def home(request):
# return render(request, 'home.html', {'var': 20})
# 7.模板中 获取当前网址，当前用户等：
def home(request):
return render(request, 'home.html', )
# 8.过滤器
def home(request):
return render(request, 'home.html', {'var': 'LOVER'})- urls.py
from django.conf.urls import include, url
from django.contrib import admin
from . import views
urlpatterns = [
# url(r'^test/',views.test,),
url(r'^home/',views.home,),
url(r'^add/(\d+)/(\d+)/$',views.add,name='h')
]需求：编写注册提交，“密码”与“确认密码”不一致，显示密码不一样。成功后在另一个页面显示 代码操作：
文件树形图显示
- ofForm.py
# -*- coding:utf-8 -*-
from django.forms import Form,widgets,fields
from django import forms
class ofForm(Form):
userName = fields.CharField(max_length=10)
password = fields.CharField(max_length=10,widget=widgets.PasswordInput)
repassword = fields.CharField(max_length=10,widget=widgets.PasswordInput)
def clean(self):
password = self.cleaned_data['password']
repassword = self.cleaned_data['repassword']
if not password == repassword:
print 'error'
myerror = 'password is different from repassword,please write again!'
raise forms.ValidationError(myerror)
return self.cleaned_data- index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>首页</title>
</head>
<body>
<form action="" method="post">
{% csrf_token %}
用户名：{{ form.userName }}<br>

确认密码：{{ form.repassword }}{{form.non_field_errors}}<br>
<input type="submit" value="注册">

]- views.py
# -*- coding: utf-8 -*-

if form.is_valid():

userModel.save()
return HttpResponse('数据提交成功！')
else:
return render(request,'index.html',{'form':form})- models.py

from __future__ import unicode_literals
from django.db import models
# Create your models here.
class UserModel(models.Model):
userName = models.CharField(max_length=10)
password = models.CharField(max_length=10)效果展示：
