当我点击提交按钮时，我的数据库中没有显示任何内容

我有一个注册表单，但是当我单击提交按钮时，我的数据库中没有任何显示，当我创建超级用户时，该用户已保存到数据库中，但是如果我使用该表单注册，它什么也不做。

表格.py

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


class RegisterForm(UserCreationForm):
    class Meta:
        model = User
        fields = (
            'first_name', 'last_name', 'email',
            'password1', 'password2'
        )

    def __init__(self, *args, **kwargs):
        super(RegisterForm, self).__init__(*args, **kwargs)
        self.fields['first_name'].widget.attrs.update({'placeholder': 'First Name', 'id': 'first-name'})
        self.fields['last_name'].widget.attrs.update({'placeholder': 'Last Name', 'id': 'last-name'})
        self.fields['email'].widget.attrs.update({'placeholder': 'Email Address', 'id': 'email-address'})
        self.fields['password1'].widget.attrs.update({'placeholder': 'New Password', 'id': 'password1'})
        self.fields['password2'].widget.attrs.update({'placeholder': 'Re-enter New Password', 'id': 'password2'})

视图.py

# login and register function
def loginAndRegister(request):
    # register form
    if request.method == 'POST':
        registerForm = RegisterForm(request.POST)
        if registerForm.is_valid():
            registerForm.save()
            messages.success(request, 'Your account has created successfully! you can log in now')
            return redirect('login')
    else:
        registerForm = RegisterForm()

    context = {'registerForm': registerForm}
    return render(request, 'account/loginAndRegisterPage.html', context)

html视图

<form method='POST'>
  {% csrf_token %}
  
  <li>{{ registerForm.first_name }}</li>
  <li>{{ registerForm.last_name }}</li>
  <li>{{ registerForm.email }}</li>
  <li>{{ registerForm.password1 }}</li>
  <li>{{ registerForm.password2 }}</li>

  <li><input type="submit" value="Create Account"></li>
</form>
