Django，保存电子邮件而不是用户名，表格不存在

Question

所以我试图设置一个表单，以便保存电子邮件而不是用户名。

当我点击注册时，表示表（app_name.pages_user）不存在？

我到底做错了什么？是因为我需要有一个表来让用户保存？我以为这只会保存到auth_users表中？

继承我的代码

models.py

class User(AbstractUser):
    first_name = models.CharField(max_length=150)
    last_name = models.CharField(max_length=150)
    email = models.EmailField(max_length=254)
    mobile_number = models.IntegerField(max_length=13)
    password = models.CharField(max_length=100)

    def __unicode__(self):
        return ""

Views.py

from pages.forms import SignUpForm

def signup(request):
    if request.method == 'POST':
        form = SignUpForm(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('home')
    else:
        form = SignUpForm()
    return render(request, 'signup.html', {'form': form})

forms.py

from django import forms
from django.contrib.auth.forms import UserCreationForm
from django.contrib.auth import get_user_model
User = get_user_model()


class SignUpForm(UserCreationForm):
    first_name = forms.CharField(max_length=30, required=False, help_text='Optional.')
    last_name = forms.CharField(max_length=30, required=False, help_text='Optional.')
    email = forms.EmailField(max_length=254, help_text='Required. Inform a valid email address.')

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