Question

我想要完成的是扩展UserCreationForm，以便在每个用户注册时为其添加电子邮件字段。目前我有一个来自UserCreationForm的表格，其中包含用户名和密码，但没有电子邮件。我使用forms.py文件扩展它，并在我的views.py中实现它。但是，当我运行测试并查看注册页面时，找不到电子邮件字段。

views.py：

chrome.webRequest.onBeforeRequest...

forms.py：

from django.shortcuts import render, redirect
from django.contrib.auth.forms import UserCreationForm
from django.contrib.auth import login as auth_login
from .forms import SignUpForm

# Create your views here.
def signup(request):
    if request.method == 'POST':
        form = SignUpForm(request.POST)
        if form.is_valid():
            user = form.save()
            auth_login(request, user)
            return redirect('index')
    else:
        form = SignUpForm()
    return render(request, 'signup.html', {'form': form})

form.html：

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

class SignUpForm(UserCreationForm):
    email = forms.CharField(max_length = 254, required = True, widget = forms.EmailInput())
    class Meta:
        model = User
        fields = ('username', 'email', 'password1', 'password2')

现在，当我实际进入登录页面时，它只显示用户名和密码字段。但是，当我刷新页面或发送无效表单时，电子邮件字段会在表单重新加载时显示。它确认当我运行测试并获得断言错误时，该字段没有出现在初始加载中：

{% load widget_tweaks %}

{% for field in form %}
  <div class="form-group">
    {{ field.label_tag }}

    {% if form.is_bound %}
      {% if field.errors %}
        {% render_field field class="form-control is-invalid" %}
        {% for error in field.errors %}
          <div class="invalid-feedback">
            {{ error }}
          </div>
        {% endfor %}
      {% else %}
        {% render_field field class="form-control is-valid" %}
      {% endif %}
    {% else %}
      {% render_field field class="form-control" %}
    {% endif %}

    {% if field.help_text %}
      <small class="form-text text-muted">
        {{ field.help_text|safe }}
      </small>
    {% endif %}
  </div>
{% endfor %}

扩展UserCreationForm的Django字段未显示在视图中
