Python - Django - activate()返回None

好的,所以我正在尝试使用Django创建一个登录。

来自views.py的

from django.shortcuts import *
from forms import UserRegistrationForm
from django.contrib.auth import authenticate, login
from django.core.mail import send_mail
from django.conf import settings
import pprint
import utils
import models
from django.http import HttpResponse
import views
from django.conf.urls import patterns, url    

def login_user(request):
    state = "Please log in below..."
    username = password = ''

    if request.POST:
        username = request.POST.get('username')
        password = request.POST.get('password')

        user = authenticate(username=username, password=password)

        if user is not None:
            if not user.is_verified:
                state = "Please check your e-mail to verify your account."
            elif user.is_active:
                login(request, user)
                state = "You're successfully logged in!"
            else:
                state = "Your account is not active, please contact the site admin."
        else:
            state = "Your username and/or password were incorrect."

        return render_to_response('myapp/dashboard.html', {'state': state}, RequestContext(request))

    else:
        return render_to_response('myapp/login.html', RequestContext(request))

我的登录模板(login.html):

<h3>Login</h3><hr />

            <form action="/login/" method="post">
        {% csrf_token %}
                {% if next %}
                <input type="hidden" name="next" value="{{ next }}" />
                {% endif %}

                username:
                <input type="text" name="username" value="{{ username }}" /><br />
                password:
                <input type="password" name="password" value="" /><br />

                <input class="btn" type="submit" value="Log In" />
            </form>

我正在使用基本的SQLite3来解决所有问题。 python manage.py syncdb运行没有问题

来自settings.py:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': 'tempDB'
    }
}

当我登录管理网站时,我看到了用户:

  

用户名:nick   密码:nick的哈希版本

当我插入一个中断(使用PBD)时,我能够看到应用程序通过login_user视图。

> ...myapp/myapp/views.py(52)login_user()
-> state = "Please log in below..."
(Pdb) n
> ...myapp/myapp/views.py(53)login_user()
-> username = password = ''
(Pdb) print username
*** NameError: name 'username' is not defined
(Pdb) n
> ...myapp/myapp/views.py(55)login_user()
-> if request.POST:
(Pdb) print username

(Pdb) n
> ...myapp/myapp/views.py(56)login_user()
-> username = request.POST.get('username')
(Pdb) print username

(Pdb) n
> ...myapp/myapp/views.py(57)login_user()
-> password = request.POST.get('password')
(Pdb) print username
nick
(Pdb) n
> ...myapp/myapp/views.py(59)login_user()
-> user = authenticate(username=username, password=password)
(Pdb) print password
nick
(Pdb) n
> ...myapp/myapp/views.py(61)login_user()
-> if user is not None:
(Pdb) print user
None

这表明它获取了用户名'nick'和密码'nick'(我设置帐户的设置)但是我遇到的问题是authenticate仍然返回None,这意味着没有设置SOMETHING正确/无效。

在login_user视图之后,'state'显示“您的用户名和/或密码不正确”。正如在views.py中所做的那样。

如果有人能够帮助我,我将不胜感激!

答案 0 :(得分:0)

(也在G +上回复)

从你的pdb会话:

(Pdb) print password
nick

如果发生了什么,那就有问题,你不同意吗? 此外,我将取消vars的初始化并改为:

username = request.POST.get('username')
password = request.POST.get('password')
if username and password:
    # Your code

request.POST.get无论如何都会工作(POST总是初始化为QueryDict),如果找不到密钥,则get()返回None,这样你就不会出现任何错误 - 这对你来说可能更容易看看发生了什么。
