一、思路

注册成功用户数据写入数据库

models相关

1.数据库中是否存在相关的表

2.创建模型类models类，需要继承与models.Model

3.创建对应字段

4.创建迁移文件python manage.py makemigrations stu

5.根据迁移文件生成数据库内容python manage.py migrate

views相关

1.编写注册方法

2.创建数据库对象

3.将页面获取的数据写入到数据库中

二、注册功能实现

1.创建项目及应用，并修改配置文件settings.py

2.项目中添加注册路径

3.应用中添加需要匹配的应用路径，并调用相关视图

# coding=utf-8
from django.conf.urls import url, include
from stu import views

urlpatterns = [
    url(r"^$", views.index_view),
    # url(r"^register/",include('stu.urls'))

]

4.register.html编写

<!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：</label><input type="text" name="uname"/>
    </p>
    <p>
        <label>密&emsp;码：</label><input type="password" name="pwd"/>
    </p>
    <p>
        <input type="submit" value="登录"/>
    </p>


</form>

</body>
</html>

5.model模型创建models.py

from django.db import models


# Create your models here.

# 定义模型类，需要继承于models.Model

class Student(models.Model):
    sname = models.CharField(max_length=30, unique=True)
    spwd = models.CharField(max_length=30)

    # class Meta:
    #  db_table="t_stu"    #应用名_模型名，小写

6.创建views.py视图函数

from django.http import HttpResponse
from django.shortcuts import render

# Create your views here.
from stu.models import Student


def index_view(request):
    m = request.method
    if m == "GET":
        return render(request, 'register.html')
    else:
        uname = request.POST.get("uname", "")
        upwd = request.POST.get("pwd", "")
        if uname and upwd:
            stu = Student(sname=uname, spwd=upwd)
            stu.save()
            return HttpResponse("注册成功")
        return HttpResponse("注册失败")
