Django导入更新表单报错：无法从users.forms导入UserRegisterForm

首次学习Django，严格按照教程操作未跳过任何步骤，却遇到报错：无法从'users.forms'导入'UserRegisterForm'。以下是相关代码及排查解决建议：

相关代码 #

views.py #

from django.shortcuts import render, redirect
from django.contrib import messages
from .forms import UserRegisterForm

def register(request):
    if request.method == 'POST':
        form = UserRegisterForm(request.POST)
        if form.is_valid():
            form.save()
            username = form.cleaned_data.get('username')
            messages.success(request, f'Account created for {username}!')
            return redirect('blog-home')
    else:
        form = UserRegisterForm()
    return render(request, 'users/register.html', {'form': form})

forms.py（原代码存在缩进问题） #

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

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

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

解决建议 #

• 修正代码缩进：Python对缩进要求严格，原forms.py中email = forms.EmailField()和class Meta块的缩进错误，会导致UserRegisterForm类定义不完整。修正后的代码应为：

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

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

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

• 确认文件位置与命名：检查forms.py是否和views.py处于同一users应用目录下，且文件名拼写正确（注意是forms.py而非form.py）。

• 验证应用配置：确保users应用已添加到项目settings.py的INSTALLED_APPS列表中：

INSTALLED_APPS = [
    'users',
    # 其他项目应用...
]

• 重启开发服务器：修改代码后可能存在服务器未自动重载的情况，重启Django开发服务器再尝试。
