我刚开始学习Django。我做了一个登记表。它的工作良好。但是我无法检查此注册表中是否存在用户名和邮件。如果我尝试使用相同的用户名注册，则会收到 (1062, "Duplicate entry 'asdasd' for key 'username'") 错误。(asdasd 我的用户名..)
我该如何解决这个问题？
表格.py
from django import forms
class RegisterForm(forms.Form):
username = forms.CharField(required=True, max_length=20, label= "Kullanıcı Adı")
email = forms.EmailField(required=True, label="E-Mail")
password = forms.CharField(max_length=20, label= "Password", widget=forms.PasswordInput)
confirm = forms.CharField(max_length=20, label="RePassword",widget=forms.PasswordInput)
def clean(self):
username = self.cleaned_data.get("username")
email = self.cleaned_data.get("email")
password = self.cleaned_data.get("password")
confirm = self.cleaned_data.get("confirm")
if password and confirm and password != confirm:
raise forms.ValidationError("Passwords dont match")
values = {
"username" : username,
"email" : email,
"password" : password,
}
return values
视图.py
from django.shortcuts import render, redirect
from .forms import RegisterForm
from django.contrib import messages
from django.contrib.auth.models import User
from django.contrib.auth import login
def register(request):
form = RegisterForm(request.POST or None)
if form.is_valid():
username = form.cleaned_data.get("username")
email = form.cleaned_data.get("email")
password = form.cleaned_data.get("password")
newUser = User(username=username)
newUser.email = email
newUser.set_password(password)
newUser.save()
login(request, newUser)
messages.success(request,"Successful on Register")
return redirect("index")
context = {
"form": form
}
return render(request, "register.html", context)
def loginUser(request):
return render(request, "login.html")
def logoutUser(request):
return render(request, "logout.html")
太感谢了！
