Python Django自定义表单-TypeError:\uuuu init\uuuuu（）接受1个位置参数，但提供了2个

当我想创建自己的表单而不是使用Django的默认表单时，我得到了以下错误：*TypeError:init（）接受1个位置参数，但给出了2个
我想通过创建Django的UserCreationForm的子类来实现这一点。我对Django很陌生，所以非常感谢您的帮助

这是我的密码：

视图.py

from django.contrib.auth import login, authenticate
from django.http import HttpResponse
from django.shortcuts import redirect, render
from SmartCookbook.modules.forms import RegisterForm
    

def register(request):
    if request.method == 'POST':
        form = RegisterForm(request.POST)
        if form.is_valid():
            form.save()
            username = form.cleaned_data.get('username')
            raw_password = form.cleaned_data.get('password1')
            user = authenticate(username=username,
                                password=raw_password)
            login(request, user)
            return redirect('homepageSmartCookbookApp')

    else:
        form = RegisterForm()
    return render(request, 'sign/register.html', {'form': form})

url.py（应用程序）

forms.py（我想在其中创建多个自定义表单类）

请注意，将.as_view（）添加到url.py没有帮助

感谢您的帮助。

欢迎使用SO，请提供python解释器的回溯。请同时显示控制台打印的错误。为什么要将

TextInput

实例传递到CharField init？CharField只接受kwargs，并且它们都不应该是TextInput@Take_Care_他该怎么办？请对解决方案做出正确的回答我需要它欢迎这样做，请提供来自python解释器的回溯，还请显示控制台打印的错误。为什么要将

TextInput

实例传递到CharField init？CharField只接受kwargs，它们都不应该是TextInput的实例@小心他该怎么办？请给我一个正确的答案，我也需要
