Django 3.0 值错误

Question

大家好，django 3.0 有问题。我正在尝试创建一个用户注册页面，但我不断收到错误。这些是我的代码

users/views.py

from .form import UserRegisterForm
from django.shortcuts import render, redirect


# Create your views here.


def register(request):
    if request.method == 'POST':
        form = UserRegisterForm(request.POST)
        if form.is_valid():
            form.save()
            return redirect('login')
        else:
            form = UserRegisterForm()
        return render(request, 'register.html', {'form': form})

form.py

from django import forms
from django.contrib.auth.forms import UserCreationForm
from django.contrib.auth.models import User


class UserRegisterForm(UserCreationForm):
    email = forms.EmailField()

    class Meta:
        model = User
        fields = ['username', 'email', 'password1', 'password2']

register.html

{% extends 'website/base.html' %}


{% block body %}
    {% include 'website/nav_bar.html' %}

    <div>
        <form method="post">
            {% csrf_token %}
            <fieldset>
                <legend>join now</legend>
                {{ form.as_p }}
            </fieldset>
            <button type="submit">submit</button>
        </form>
    </div>
{% endblock body %}

这里

def register(request):
    if request.method == 'POST':
        form = UserRegisterForm(request.POST)
        if form.is_valid():
            form.save()
            return redirect('login')
        else:
            form = UserRegisterForm()
        return render(request, 'register.html', {'form': form})

你忘记了普通GET请求的情况:)

类似的东西

def register(request):
    form = UserRegisterForm()

    if request.method == 'POST':
        form = UserRegisterForm(request.POST)
        if form.is_valid():
            form.save()
            return redirect('login')
    return render(request, 'register.html', {'form': form})
