在线教育平台，用户注册（8）

1.初步视图：

users/views.py

class RegisterView(View):
    '''用户注册'''
    def get(self,request):
        return render(request,'register.html')

 用户以get方式，直接返回注册页面

2设计路由：

# MxOnline/urls.py
from users.views import RegisterView

    path('register/',RegisterView.as_view(),name = 'register'),

修改index.html

点 “注册 ”应该跳到用户注册页面

 <a style="color:white" class="fr registerbtn" href="/register/">注册</a>

 <a style="color:white" class="fr loginbtn" href="/login/">登录</a>

修改register.html中的静态文件地址

{% load staticfiles %}

<link rel="stylesheet" type="text/css" href="{% static 'css/reset.css' %}">
    <link rel="stylesheet" type="text/css" href="{% static 'css/login.css' %}">

<script src="{% static 'js/jquery.min.js' %}" type="text/javascript"></script>
<script src="{% static 'js/unslider.js' %}" type="text/javascript"></script>
<script src="{% static 'js/validateDialog.js' %}"  type="text/javascript"></script>
<script src="{% static 'js/login.js' %}"  type="text/javascript"></script>

验证码：

验证码库：django-simple-captcha，这里面有介绍这个第三方库的使用方法

 安装：

pip install  django-simple-captcha
Add captcha to the INSTALLED_APPS in your settings.py

INSTALLED_APPS = [
    'captcha',
]
Add an entry to your urls.py:

urlpatterns = [
    path('captcha/',include('captcha.urls')),
]
生成到数据库

python manage.py makemigrations

python manage.py migrate

在注册页面显示验证码

 定义我们的register form:

# users/forms.py

from django import forms
from captcha.fields import CaptchaField


class LoginForm(forms.Form):
    '''登录验证表单'''

    username = forms.CharField(required=True)
    password = forms.CharField(required=True,min_length=5)


class RegisterForm(forms.Form):
    '''注册验证表单'''

    email = forms.EmailField(required=True)
    password = forms.CharField(required=True,min_length=5)
    # 验证码
    captcha = CaptchaField(error_messages={'invalid':'验证码错误'})

通过{{ register_form.captcha }}获取验证码

<div class="form-group marb8 captcha1 ">
     <label>验&nbsp;证&nbsp;码</label>
     {{ register_form.captcha }}
</div>

视图逻辑：

# users/views.py

from django.shortcuts import render
from django.contrib.auth import authenticate,login

from django.contrib.auth.backends import ModelBackend
from .models import UserProfile,EmailVerifyRecord
from django.db.models import Q
from django.views.generic.base import View
from .forms import LoginForm,RegisterForm
from django.contrib.auth.hashers import make_password
from utils.email_send import send_register_eamil

#邮箱和用户名都可以登录
# 基础ModelBackend类，因为它有authenticate方法
class CustomBackend(ModelBackend):
    def authenticate(self, request, username=None, password=None, **kwargs):
        try:
            # 不希望用户存在两个，get只能有一个。两个是get失败的一种原因 Q为使用并集查询
            user = UserProfile.objects.get(Q(username=username)|Q(email=username))

            # django的后台中密码加密：所以不能password==password
            # UserProfile继承的AbstractUser中有def check_password(self, raw_password):
            if user.check_password(password):
                return user
        except Exception as e:
            return None


class LoginView(View):
    '''用户登录'''

    def get(self,request):
        return render(request, 'login.html')

    def post(self,request):
        # 实例化
        login_form = LoginForm(request.POST)
        if login_form.is_valid():
            # 获取用户提交的用户名和密码
            user_name = request.POST.get('username', None)
            pass_word = request.POST.get('password', None)
            # 成功返回user对象,失败None
            user = authenticate(username=user_name, password=pass_word)
            # 如果不是null说明验证成功
            if user is not None:
                if user.is_active:
                    # 只有注册激活才能登录
                    login(request, user)
                    return render(request, 'index.html')
                else:
                    return render(request, 'login.html', {'msg': '用户名或密码错误', 'login_form': login_form})
            # 只有当用户名或密码不存在时，才返回错误信息到前端
            else:
                return render(request, 'login.html', {'msg': '用户名或密码错误','login_form':login_form})

        # form.is_valid（）已经判断不合法了，所以这里不需要再返回错误信息到前端了
        else:
            return render(request,'login.html',{'login_form':login_form})


# 激活用户
class ActiveUserView(View):
    def get(self, request, active_code):
        # 查询邮箱验证记录是否存在
        all_record = EmailVerifyRecord.objects.filter(code = active_code)

        if all_record:
            for record in all_record:

                user.is_active = True
                user.save()
         # 验证码不对的时候跳转到激活失败页面
        else:
            return render(request,'active_fail.html')
        # 激活成功跳转到登录页面
        return render(request, "login.html", )


class RegisterView(View):
    '''用户注册'''
    def get(self,request):
        register_form = RegisterForm()
        return render(request,'register.html',{'register_form':register_form})

    def post(self,request):
        register_form = RegisterForm(request.POST)
        if register_form.is_valid():

views.py所以代码
