【问题描述】：

刚开始接触 Django，在扩展经典的 UserRegistrationForm 时遇到了困难。我已经按照教程here 进行了操作，这很棒，但是浏览器中的 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，现在只想在浏览器中查看基本信息。谁能解释为什么我看到除了 username、password、password2 和 email 之外的所有其他字段？

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>

为什么其他人都出现了？对此的任何帮助将不胜感激:)

【解决方案1】：

您的MyRegistrationForm 的Meta 定义中有错字：

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

应该是fields 而不是field。
