为什么电子邮件行没有显示在注册表中？

如何解决为什么电子邮件行没有显示在注册表中？

我正在尝试通过邮件进行注册，按照本指南进行了所有操作

https://medium.com/@frfahim/django-registration-with-confirmation-email-bb5da011e4ef

但在注册表单中没有显示带有电子邮件的行，尽管我在forms.py

from django import forms
from .models import Post,Comment
from django import forms
from django.contrib.auth.forms import UserCreationForm
from django.contrib.auth.models import User


class CommentForm(forms.ModelForm):
    class Meta:
        model = Comment
        fields = ('name','body')

        widgets = {
            'name': forms.TextInput(attrs={'class': 'form-control'}),'body': forms.Textarea(attrs={'class': 'form-control'}),}


class SignupForm(UserCreationForm):
    email = forms.EmailField(max_length=200,help_text='required')
    class Meta:
        model = User
        fields = ('username','email','password1','password2')

signup.html

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css">
{% block content %}
  <h2>Sign up</h2>
  <form method="post">
    {% csrf_token %}
      {% for field in form %}
      <p>
        {{ field.label_tag }}<br>
        {{ field }}
        
        {% for error in field.errors %}
          <p style="color: red">{{ error }}</p>
        {% endfor %}
      </p>
      {% endfor %}
    <button type="submit">Sign up</button>
  </form>
{% endblock %}
