四、用户注册
1、用户基本注册get请求方式实现
（1）准备工作
将资料包中的register.html文件复制到templates目录下。
（2）编写视图函数
# users/views.py def register(request): if request.method == ‘GET‘: return render(request, ‘register.html‘)
（3）配置子路由
# users/usl.py from users.views import register app_name = ‘users‘ urlpatterns = [ path(‘register‘, register, name=‘register‘) ]
（4）修改base.html中注册的url
<a style="color:white" class="fr registerbtn" href="{% url ‘users:register‘ %}">注册</a>
启动项目，进入首页点击“注册”，页面正常跳转。
2、用户基本注册post请求方式实现(使用form组件)
（1）修改register.html页面form表单提交路径
<form id="email_register_form" method="post" action="{% url ‘users:register‘ %}" autocomplete="off">
（2）加入防跨域攻击（在form标签下）
{% csrf_token %}
（3）编写forms.py脚本
# users/forms.py from django import forms class UserRegisterForm(forms.Form): email = forms.EmailField(required=True) # 规定用户名就是email,不能为空 password = forms.CharField(required=True, min_length=6, max_length=16, error_messages={ ‘required‘: ‘密码不能为空‘, ‘min_length‘: ‘密码至少6位‘, ‘max_length‘: ‘密码不能超过16位‘ })
（4）编写试图函数
from django.shortcuts import render, redirect from django.urls import reverse from users.models import UserProfile from users.forms import UserRegisterForm from django.db.models import Q def index(request): return render(request, ‘index.html‘) def register(request): if request.method == ‘GET‘: return render(request, ‘register.html‘) else: user_register_form = UserRegisterForm(request.POST) if user_register_form.is_valid(): # 判断是否合法 email = user_register_form.cleaned_data[‘email‘] password = user_register_form.cleaned_data[‘password‘] user_list = UserProfile.objects.filter(Q(username=email) | Q(email=email)) if user_list: return render(request, ‘register.html‘, { ‘msg‘: ‘用户已经存在‘ }) else: a = UserProfile() a.username = email # 用户名存库 a.set_password(password) # 密码存库，经过处理 a.email = email a.save() # 保存 return redirect(reverse(‘index.html‘)) else: return render(request, ‘register.html‘,{ ‘user_register_form‘: user_register_form })
（5）、修改register,html文件，加入报错信息
找到form抱歉下的name=‘error btns‘的div,动态添加报错信息
{{ msg }}
{% for key,err in user_register_form.items %}
{{ err }}
{% endfor %}
启动项目进行验证。
如图我们故意输错，会给我们提示错误。按要求输入会自动跳转到首页。
