我的用户登录在身份验证过程中存在一些问题。 我正在使用Django 1.9和Python 3.6
user = authenticate(username = username,password = password)
将用户返回为无
这就是我 Accounts / views.py 查找登录信息的方式
def register(request):
registered = False
if request.method == 'POST':
reg_form = RegistrationForm(data=request.POST)
profile_form = UserProfileForm(data=request.POST)
if reg_form.is_valid() and profile_form.is_valid():
user = reg_form.save()
# print('before set password = ', user.password)
user.set_password(user.password)
# print('after set password = ', user.password)
user.save()
print(user.password)
profile = profile_form.save(commit=False)
profile.user = user
profile.email = user.email
profile.first_name = user.first_name
profile.last_name = user.last_name
if 'profile_pic' in request.FILES:
profile.profile_pic = request.FILES['profile_pic']
print('uploading pic .....')
profile.save()
args = {'reg_form': reg_form, 'profile_form': profile_form, 'registered': True}
head_list.update(args)
return render(request, 'registration.html', head_list)
else:
print(reg_form.errors, profile_form.errors)
args = {'reg_form': reg_form.errors, 'profile_form': profile_form.errors, 'registered': False}
head_list.update(args)
return render(request, 'registration.html', head_list, args)
else:
reg_form = RegistrationForm()
profile_form = UserProfileForm()
args = {'reg_form': reg_form, 'profile_form': profile_form, 'registered': False}
head_list.update(args)
print(head_list)
return render(request, 'registration.html', head_list)
def login_view(request):
params = {}
params.update(csrf(request))
if request.method == 'POST':
form = LoginForm(request.POST)
if form.is_valid():
username = form.cleaned_data.get('username')
password = form.cleaned_data.get('password')
# First get the username and password supplied
# username = request.POST.get('username', '')
# password = request.POST.get('password', '')
# Django's built-in authentication function:
print(username, password)
user = authenticate(username=username, password=password)
print('after aunthenticate', user)
# If we have a user
if user:
# Check it the account is active
if user.is_active:
# Log the user in.
login(request, username)
# Send the user back to some page.
# In this case their homepage.
# return HttpResponseRedirect(reverse('/user_login/'))
return render_to_response('user_login.html', RequestContext(request, {}))
else:
# If account is not active:
return HttpResponse("Your account is not active.")
else:
print("Someone tried to login and failed.")
print("They used username: {} and password: {}".format(username, password))
return HttpResponse("Invalid login details supplied.")
else:
form = LoginForm()
args = {'form': form}
head_list.update(args)
# Nothing has been provided for username or password.
return render(request, 'login.html', head_list)
login.html页面如下所示
{% block content %}
<section class="container">
<h1>LiquorApp Login Console</h1>
<div class="login">
<h1>Login to WebApp</h1>
<form method="post" action="/user_login/">
{% csrf_token %}
{{ form.as_p }}
{% comment %}Username: <input type="text" name="username" value="" size="50" />
<br />{% endcomment %}
{% comment %}<p><input type="text" name="username" value="" id="username" placeholder="username"></p>
<p><input id ="password" type="password" name="password" value="" placeholder="password"></p>
<p class="remember_me">{% endcomment %}
<label>
<input type="checkbox" name="remember_me" id="remember_me">
Remember me on this computer
</label>
</p>
<p class="submit"><input type="submit" name="commit" value="Login"></p>
</form>
</div>
</section>
{% endblock %}
请告知我在哪里做错了我的身份验证模块没有返回。
我还在settings.py文件中添加了以下内容
AUTHENTICATION_BACKENDS = (
'django.contrib.auth.backends.ModelBackend',
)

Django 2.1身份验证返回 users 进行任何身份验证,只有 user.is_active = TRUE 并且您需要先保存 form.save(commit = False),然后设置自定义变量
if form.is_valid():
user= form.save(commit=False)
user.active=True
user.staff=False
user.admin=False
user.save()
messages.success(request, 'Account created successfully')

在Django 1.11中调用user.is_active is True
之前确保authenticate(username=user.username, password=password, request=request)
。
它在Django 1.8中运行良好,但在LTS 1.8和LTS 1.11之间的某个地方,他们在user.is_active
类中添加了对ModelBackend
的额外检查:
class ModelBackend(object):
"""
Authenticates against settings.AUTH_USER_MODEL.
"""
def authenticate(self, request, username=None, password=None, **kwargs):
if username is None:
username = kwargs.get(UserModel.USERNAME_FIELD)
try:
user = UserModel._default_manager.get_by_natural_key(username)
except UserModel.DoesNotExist:
# Run the default password hasher once to reduce the timing
# difference between an existing and a non-existing user (#20760).
UserModel().set_password(password)
else:
if user.check_password(password) and self.user_can_authenticate(user):
return user
def user_can_authenticate(self, user):
"""
Reject users with is_active=False. Custom user models that don't have
that attribute are allowed.
"""
is_active = getattr(user, 'is_active', None)
return is_active or is_active is None
至于使用Django内置身份验证视图的建议,它们对于自定义非标准身份验证并不方便。

删除
user.set_password(user.password)
答案 3 :(得分:0)
您需要为User类定义check_password
def check_password(self, raw_password):
if self.password == raw_password:
return True
else:
return False
因为如果你检查django.contrib.auth.models下的源代码, check_password()raise和NotImplemented错误。
