在扩展Django UserCreationForm时删除不需要的字段

Question

刚开始进入Django并在扩展经典UserRegistrationForm时陷入困境。我已经按照教程here这很好，但浏览器中的Html表单显示了我不想要的字段。我现在只想扩展电子邮件，但想稍后添加名字和姓氏。

请注意我还没有CSS，只想在浏览器中查看基本信息。除了用户名，密码，密码2 和电子邮件之外，还有人可以解释为什么我会看到所有其他字段吗？

forms.py

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

class MyRegistrationForm(UserCreationForm): 
email = forms.EmailField(required=True)

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

def save(self, commit=True)
    user = super(MyRegistrationForm, self).save(commit=False)
    user.email = self.cleaned_data['email'] #validated before committing to database

    if commit:
        user.save()
    return user

views.py

from django.shortcuts import render_to_response #allows you to render a template back to the browser
from django.http import HttpResponseRedirect #allows the browser to redirect to another url
from django.contrib import auth
from django.core.context_processors import csrf # method to stop hackers submitting requests
from fantasymatchday_1.forms import MyRegistrationForm #A user registration form I created that inherits the UserCreationForm

def register_user(request):
        if request.method == 'POST':
           form = MyRegistrationForm(request.POST) #create a form object
           if form.is_valid(): #if the form is valid, save the form
              form.save()
              return HttpResponseRedirect('/register_success')

        args = {}
        args.update(csrf(request))

        args['form'] = MyRegistrationForm()
        #print args
        return render_to_response('register.html', args)

def register_success(request):
    return render_to_response('register_success.html')

register.html

   <h2> Register </h2>

   <form action="/register/" method="post">{% csrf_token %}
   {{form}}

   <input type="submit" value="Register" />

   </form>

为什么所有其他人都出现了？任何有关这方面的帮助将不胜感激：）

您的MyRegistrationForm Meta定义中有一个拼写错误：

field =  ('username','email','first_name','last_name','password1', 'password2')

应该是fields而不是field。
