Django学习(实现注册功能)

1.注册功能

1).创建Django项目test，然后在test中添加应用stu：python manage.py startapp stu

在setting.py中添加新应用stu

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'stu' #添加新应用 stu
]

2).配置urls，stu/urls

#testurls.py
from django.conf.urls import url, include
from django.contrib import admin
import views

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^register/',include('stu.urls'))  
]

#testurls.py
#coding=utf-8
from django.conf.urls import url
import views

urlpatterns=[
    url(r'^$',views.index_view),

]

3).创建register.html文件

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    <form action="/register/" method="post">
        {% csrf_token %}
        <p>
            <label>用户名：<input type="text" name="uname"></label>
        </p>
        <p>
            <label >密&emsp;码：<input type="text" name="pwd"></label>
        </p>
        <p>
            <lable><input type="submit" value="注册"></lable>
        </p>
    </form>
</body>
</html>

4).创建学生模型 model.py

# -*- coding: utf-8 -*-
from __future__ import unicode_literals
from django.db import models
# Create your models here.
class Student(models.Model):
    sname = models.CharField(max_length=30)
    spwd = models.CharField(max_length=30)

5).创建数据库表(当前连接sqlite3数据库)

#创建当前应用stu的迁移文件
python manage.py makemigrations stu
 
#生成数据库表
 python manage.py migrate

6).配置视图函数 view.py

# -*- coding: utf-8 -*-
from __future__ import unicode_literals
from django.http import HttpResponse
from django.shortcuts import render
# Create your views here.
from stu.models import Student
def index_view(request):
    #1.接收请求参数
    if request.method == 'GET':
        return render(request,'register.html')
    #2.非空对象
    else:
        uname = request.POST.get("uname","")
        pwd = request.POST.get("pwd","")
        #3.创建模型对象
        if uname and pwd :
            student = Student(sname=uname ,spwd=pwd)
            #4.插入数据库
            student.save()
            return HttpResponse('注册成功')
    return HttpResponse("注册失败")

7).访问登录页面 127.0.0.1:8000/register/
