MultiValueDictKeyError：“'password'”

Question

我的网址如下所示：

url(r'^register/$', views.register, name='register')

我的views.py中的函数就像：

from django.shortcuts import render
from django.http import HttpResponseRedirect
from django.core.urlresolvers import reverse
from django.contrib.auth import login, logout, authenticate
from django.contrib.auth.forms import UserCreationForm

def register(request):
    """register"""
    if request.method != 'POST':
        #we present a blank form
        form = UserCreationForm()
    else: 
        #the post the data the users have just filled
        form = UserCreationForm(data=request.POST)

        if form.is_valid():
            new_user = form.save()
            # we use the date to redirect our user to the page of login
            authenticated_user = authenticate(username=new_user.username,
                                              password=request.POST['password'])
            login(request, authenticated_user)
            return HttpResponseRedirect(reverse('learning_logs:index'))

    context = {'form': form}
    return render(request, 'users/register.html', context) 

我的register.html：

{% extends "learning_logs/base.html" %}
{% block content %}
    <form action="{% url 'users:register' %}" method="post">
        {% csrf_token %}
        {{ form.as_p }}
        <button name="submmit">Register</button>
        <input type="hidden" name="next" value="{% url 'learning_logs:index' %}"/>
    </form>
{% endblock content %}

当我进行注册时，会出现错误，如MultiValueDictKeyError：“'password'”

有人可以看看并帮我一把吗？非常感谢！

如果您选中UserCreationForm，则会看到它没有名为password的字段，但它有两个：password1和password2。您可以将代码更改为：

if form.is_valid():
    new_user = form.save()
    # we use the date to redirect our user to the page of login
    authenticated_user = authenticate(username=new_user.username,
                                      password=form.cleaned_data['password1'])
    #                                          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
    login(request, authenticated_user)
    return HttpResponseRedirect(reverse('learning_logs:index'))

但是，您可能希望避免处理密码，只需直接使用login()，而无需通过authenticate()：

if form.is_valid():
    user = form.save()
    login(request, user)
    return HttpResponseRedirect(reverse('learning_logs:index'))
