Django 用户创建表单

from django.contrib.auth.forms import UserCreationForm  

from django.shortcuts import render  from django.contrib.auth.forms import UserCreationForm  # Create your views here.  def register(request):      if request.POST == 'POST':          form = UserCreationForm()          if form.is_valid():              form.save()      messages.success(request, 'Account created successfully')      else:          form = UserCreationForm()      context = {          'form':form      }      return render(request, 'register.html', context)

from django.urls import path  from django.contrib import admin  from sampleapp.views import register  
urlpatterns = [     path('admin/', admin.site.urls),      path('register', register, name = 'register')  ]

• 用户填写详细信息并点击提交按钮。
• 这些网站会在提交的邮件中发送验证链接。
• 用户在输入的邮件中收到验证链接。

from django import forms  from django.contrib.auth.models import User  from django.contrib.auth.forms import UserCreationForm  from django.core.exceptions import ValidationError  from django.forms.fields import EmailField  from django.forms.forms import Form  class CustomUserCreationForm(UserCreationForm):      username = forms.CharField(label='username', min_length=5, max_length=150)      email = forms.EmailField(label='email')      password1 = forms.CharField(label='password', widget=forms.PasswordInput)      password2 = forms.CharField(label='Confirm password', widget=forms.PasswordInput)      def username_clean(self):          username = self.cleaned_data['username'].lower()          new = User.objects.filter(username = username)          if new.count():              raise ValidationError("User Already Exist")          return username      def email_clean(self):          email = self.cleaned_data['email'].lower()          new = User.objects.filter(email=email)          if new.count():              raise ValidationError(" Email Already Exist")          return email      def clean_password2(self):          password1 = self.cleaned_data['password1']          password2 = self.cleaned_data['password2']          if password1 and password2 and password1 != password2:              raise ValidationError("Password don't match")          return password2      def save(self, commit = True):          user = User.objects.create_user(              self.cleaned_data['username'],              self.cleaned_data['email'],              self.cleaned_data['password1']          )          return user

• username_clean ()将防止输入重复的用户名。
• email_clean ()将防止输入重复的电子邮件。
• clean_password2 ()方法将检查两个密码是否匹配

from django.contrib.auth import forms  from django.shortcuts import redirect, render  from django.contrib import messages  from django.contrib.auth.forms import UserCreationForm  from .forms import CustomUserCreationForm  # Create your views here.  def register(request):      if request.POST == 'POST':          form = CustomUserCreationForm()          if form.is_valid():              form.save()      else:          form = CustomUserCreationForm()      context = {          'form':form      }      return render(request, 'register.html', context)
