名称 'user' 未定义

Question

我试图在不使用 usercreationform 的情况下制作自定义注册页面我制作了模型并导入了它但是当我运行它时我总是遇到这个错误 /register 处的名称错误名称 'user' 未定义该行特别是：
如果 user.password != user.repassword:

我尝试将方法更改为 GET 而不是 POST，但我得到了一个不同的错误 MultiValueDictKeyError 'fname'

views.py

from django.shortcuts import render,redirect
from .models import User
from django.contrib import messages




def home(request):
    return render(request, 'home.html')


def register(request):
    global user
    if request.method == 'POST':
        user = User()
        user.fname = request.POST['fname']
        user.lname = request.POST['lname']
        user.email = request.POST['email']
        user.password = request.POST['password']
        user.repassword = request.POST['repassword']

    if user.password != user.repassword:
        return redirect("register")
    elif user.fname == "" or user.password == "" :
        messages.info(request,f"some fields are empty")
        return redirect("register")
    else:
        user.save()
    return render(request, 'register.html')

Answer 1

这是你想要的吗？:

def register(request):
    user = request.user
    if request.method == 'POST':
        user = User()
        user.fname = request.POST['fname']
        user.lname = request.POST['lname']
        user.email = request.POST['email']
    ....
    ....

Answer 2

如果请求方法不是POST:

，你应该做点什么

from django.core.exceptions import BadRequest

def register(request):
    if request.method == 'POST':
        user = User()
        user.fname = request.POST['fname']
        user.lname = request.POST['lname']
        user.email = request.POST['email']
        user.password = request.POST['password']
        user.repassword = request.POST['repassword']
       
        if user.password != user.repassword:
            return redirect("register")
        elif user.fname == "" or user.password == "" :
            messages.info(request,f"some fields are empty")
            return redirect("register")

        user.save()
        return render(request, 'register.html')
    else:
        raise BadRequest()  # Or do something else

此视图适用于 POST 个请求。
