如何验证用户
How to authenticate a User
我创建了两种不同类型的用户 - 卡车和公司。这是我的用户注册页面
注册后,用户是卡车还是公司的数据会进入数据库。
在我的登录页面,
只需输入电子邮件和密码。在我的自定义用户创建表单中,我添加了字段 username = email.
当我尝试使用有效凭据登录时,该页面未根据 user-type 将我重定向到特定页面。相反,我在 login.html 中为无效凭据创建的错误正在引发 - "Your email and password didn't match. Please try again."
这是我的代码:
views.py:
def login_view(request):
title = "Login"
if request.method == 'POST':
form = LoginForm(data=request.POST)
email = request.POST.get('email', '')
password = request.POST.get('password', '')
user = auth.authenticate(username=email, password=password)
if form.is_valid():
auth.login(request, user)
user_type = form.cleaned_data['Label']
if user.is_active & user_type == 'Truck':
return HttpResponseRedirect('/post_load/')
elif user_type == 'Company':
return HttpResponseRedirect('/live_deal/')
else:
form = LoginForm()
return render(request, 'registration/login.html', {'form' : form, 'title': title})
urls.py:
# url(r'^login/$', views.login_view),
# url(r'^accounts/login/$', views.login_view),
url(r'^login/$', 'django.contrib.auth.views.login', {'authentication_form': LoginForm}),
url(r'^accounts/login/$', 'django.contrib.auth.views.login', {'authentication_form': LoginForm}),
forms.py:
class LoginForm(auth.forms.AuthenticationForm):
email = forms.EmailField(label=_("Email"),widget=forms.EmailInput)
CHOICES= (('Truck', 'Truck'),('Company', 'Company'),)
Label = forms.ChoiceField(choices=CHOICES, label='Label', widget=forms.RadioSelect())
login.html:
{%extends "registration/header.html"%}
{% block content %}
{% if form.errors %}
<p>Your email and password didn't match. Please try again.</p>
{% endif %}
<form class="form-horizontal" method="post" action = "." >{%csrf_token%}

这个错误相当广泛。您可以遍历它以查看实际错误。
更好;不要使用您自己的身份验证系统,只需使用 Django 的内置系统,它还允许您向用户模型添加额外的字段。
示例:
from django.contrib.auth import authenticate, login
def my_view(request):
username = request.POST['username']
password = request.POST['password']
user = authenticate(username=username, password=password)
if user is not None:
if user.is_active:
login(request, user)
# Redirect to a success page.
else:
# Return a 'disabled account' error message
...
else:
# Return an 'invalid login' error message.
...
注意,你不需要自己写登录视图,你也可以使用Django的登录系统来处理表单,传递reset/change,urls和模板(你可以用自己的模板覆盖):
网址:
urlpatterns = [
url('^', include('django.contrib.auth.urls')),
]
然后 /login/
将是您的登录页面。
与 Django contrib 身份验证模块一起使用后,使用您自己的自定义 HTML 登录表单对其进行扩展。
