我有一个名为log的django项目和一个名为basic_app的应用程序。我创建了一个注册表，但是当我想创建一个user_login时，出现此错误：
位于/ basic_app / user_login /的NoReverseMatch 找不到'user_login'的反向按钮。 'user_login'不是有效的视图函数或模式名称。
views.py：
from django.shortcuts import render
from basic_app.forms import UserForm, UserProfileInfoForm
from django.contrib.auth import authenticate, login, logout
from django.http import HttpResponseRedirect, HttpResponse
from django.core.urlresolvers import reverse
from django.contrib.auth.decorators import login_required
# Create your views here.
def index(request):
return render(request, 'basic_app/index.html')
@login_required
def special(request):
return HttpResponse('You are loged in!')
@login_required
def user_logout(request):
logout(request)
return HttpResponseRedirect(reverse('index'))
def register(request):
registered = False
if request.method == 'POST':
user_form = UserForm(data=request.POST)
profile_form = UserProfileInfoForm(data=request.POST)
if user_form.is_valid() and profile_form.is_valid():
user = user_form.save()
user.set_password(user.password)
user.save()
profile = profile_form.save(commit=False)
profile.user = user
if 'profile_pic' in request.FILES:
profile.profile_pic = request.FILES[
'profile_pic'
]
profile.save()
registered = True
else:
print(user_form.errors, profile_form.errors)
else:
user_form = UserForm()
profile_form = UserProfileInfoForm()
return render(request, 'basic_app/registration.html',
{'user_form':user_form,
'profile_form':profile_form,
'registered':registered})
def user_login(request):
if request.method == 'POST':
username = request.POST.get('username')
password = request.POST.get('password')
user = authenticate(username = username, password = password)
if user:
if user.is_active:
login(request, user)
return HttpResponseRedirect(reverse('index'))
else:
return HttpResponse('Account Not Active.')
else:
print('Someone tried to login and failed!')
print('username:{} and password:{}'.format(username, password))
return HttpResponse('invalid login details supplied!')
else:
return render(request, 'basic_app/login.html',{})
