• Django实现用户注册登录


    学习Django中:试着着写一个用户注册登录系统,开始搞事情 =====O(∩_∩)O哈哈~=====

    =================

    Ubuntu

    python 2.7.12

    Django 1.10.4

    IDE:Pycharm

    Bootstrap(其实没怎么用~~)

    =================

    新建项目:(我是直接用pycharm直接生成的)

    使用终端:

    (创建项目)django-admin.py startproject mysite

    (进入mysite新建app)django-admin.py startapp app01

    记得在settings.py里面添加app

     设计模型:

    /mysite/app01/models.py:

    from __future__ import unicode_literals
    
    from django.db import models
    
    # Create your models here.
    
    class User(models.Model):
        username = models.CharField(max_length=50)
        password = models.CharField(max_length=50)
        email = models.EmailField()

    创建User类,存放 username、password、email三个字段

    同步数据库:

    Python manage.py makemigrations

    python manage.py migrate

    Django会自动创建一系列表

    没有自动创建superuser.......咱们手动创建:

    python manage.py createsuperuser

    设计逻辑视图(views):(使用表单)

    /mysite/app01/views.py:

    #coding=utf-8
    from django.shortcuts import render,render_to_response
    from django.http import HttpResponse
    from django import forms
    from models import User
    # Create your views here.
    class UserForm(forms.Form):
        username = forms.CharField(label='用户名',max_length=50)
        password = forms.CharField(label='密码',widget=forms.PasswordInput())
        email = forms.EmailField(label='邮箱')
    
    def regist(request):
        if request.method == 'POST':    
            userform = UserForm(request.POST)
            if userform.is_valid():
                username = userform.cleaned_data['username']
                password = userform.cleaned_data['password']
                email = userform.cleaned_data['email']
    
                User.objects.create(username=username,password=password,email=email)
                User.save()
    
                return HttpResponse('regist success!!!')
        else:
            userform = UserForm()
        return render_to_response('regist.html',{'userform':userform})
    
    def login(request):
        if request.method == 'POST':
            userform = UserForm(request.POST)
            if userform.is_valid():
                username = userform.cleaned_data['username']
                password = userform.cleaned_data['password']
    
                user = User.objects.filter(username__exact=username,password__exact=password)
    
                if user:
                    return render_to_response('index.html',{'userform':userform})
                else:
                    return HttpResponse('用户名或密码错误,请重新登录')
    
        else:
            userform = UserForm()
        return render_to_response('login.html',{'userform':userform})

    注释:

    label:标签

    widget:装饰

    widget=forms.PasswordInput():设置密码字段

    设计模板文件

    在templates里面新建index.html、regist.html、login.html

    regist.html

    <!DOCTYPE html>
    {% load static %}
    <html lang="zh-CN"><head>
    <meta http-equiv="content-type" content="text/html; charset=UTF-8">

        <![endif]-->
      </head>
    <style>
            html,body{text-align:center;margin:0px auto;}
    </style>
    <body>
    <h1>注册页面</h1>
    <form method = 'post' enctype="multipart/form-data">
    {{userform.as_p}}
    <input type="submit" value = "Regist" />
    </form>
    </body>
    </html>

     login.html

    <!DOCTYPE html>
    {% load static %}
    <html lang="zh-CN"><head>
    <meta http-equiv="content-type" content="text/html; charset=UTF-8">

        <!--[if lt IE 9]><script src="../../assets/js/ie8-responsive-file-warning.js"></script><![endif]-->

          <script src="https://cdn.bootcss.com/respond.js/1.4.2/respond.min.js"></script>
        <![endif]-->
      </head>
    <style>
            html,body{text-align:center;margin:0px auto;}
    </style>
    <body>
    <h1>登录页面</h1>
    <form method = 'post' enctype="multipart/form-data">
    {{userform.as_p}}
    <input type="submit" value = "Login" />
    </form>
    </body>
    </html>

     index.html

    <!DOCTYPE html>
    <html lang="en">
    <head>
        <meta charset="UTF-8">
        <title>主页</title>
    </head>
    <style>
            html,body{text-align:center;margin:0px auto;}
    </style>
    <body>
    <h1>Hello Word!</h1>
    </body>
    </html>

     设计urls

    /mysite/urls.py

    from django.conf.urls import url,include
    from django.contrib import admin
    from app01 import urls
    import app01
    
    urlpatterns = [
        url(r'^admin/', admin.site.urls),
        url(r'',include(app01.urls)),
    ]

    /mysite/app01/urls.py

    from django.conf.urls import url,include
    from django.contrib import admin
    import views
    admin.autodiscover()
    
    urlpatterns = [
        url(r'^index/$',views.index),
        url(r'^login/$',views.login),
        url(r'^regist/$',views.regist),
    
    ]

     使用admin后台管理注册的用户

    在models.py里面设计一个UserAdmin类,用来记录注册用户的信息

    /mysite/app01/models.py

    from __future__ import unicode_literals
    from django.contrib import admin
    from django.db import models
    
    # Create your models here.
    
    class User(models.Model):
        username = models.CharField(max_length=50)
        password = models.CharField(max_length=50)
        email = models.EmailField()
    
    class UserAdmin(admin.ModelAdmin):
        list_display = ('username','password','email')
    
    admin.site.register(User,UserAdmin)

     同步一下数据库(方法同上)
