Question

我一直在尝试添加注册/登录/注销功能。用户创建的用户似乎运行良好，因为创建的用户显示在Django admin中并显示在数据库中。但是，每当我尝试实现登录功能时，它就永远无法工作。我认为我已将问题缩小到#Convert time to POSIXct df[3:4] <- lapply(df[3:4], as.POSIXct) #Get min start.time df1 <- aggregate(start.time~species + date, df, min, na.rm = TRUE, na.action = "na.pass") #Get max end.time df2 <- aggregate(end.time~species + date, df, max, na.rm = TRUE, na.action = "na.pass") #Get combined remarks df3 <- aggregate(remarks~species + date, df, function(x) toString(unique(na.omit(x))), na.action = "na.pass") #merge into one dataset Reduce(merge, list(df1, df2, df3))。

我已经尝试了一切，无论我做什么，df <- structure(list(species = structure(c(1L, 1L, 1L, 1L), .Label = "A", class = "factor"), date = structure(c(1L, 1L, 2L, 2L), .Label = c("2020-02-01", "2020-02-02"), class = "factor"), start.time = structure(c(1L, 2L, 1L, NA), .Label = c("2020-02-018:00:00", "2020-02-019:00:00" ), class = "factor"), end.time = structure(c(2L, 3L, NA, 1L), .Label = c("2020-02-0111:30:00", "2020-02-0112:00:00", "2020-02-0200:00:00"), class = "factor"), remarks = structure(c(2L, NA, 1L, NA), .Label = c("medium", "slow"), class = "factor")), class = "data.frame", row.names = c(NA, -4L))函数始终返回authenticate()。我提供的用户名和密码显然已存储，但似乎并不能正确获取密码，因为在authenticate()视图中打印出None会得到raw_password = form.cleaned_data.get('password1')。

如何使登录功能正常工作？

在 urls.py

中

login_user

在 views.py

中

None

在 register.html

urlpatterns = [
    path('register', views.register_user, name='register'),
    path('login', views.login_user, name='login'),
    path('logout', views.logout_user, name='logout'),
]

在 login.html

中

def register_user(request):
    if request.method == 'POST':
        form = UserCreationForm(request.POST)

        if form.is_valid():
            form.save()
            username = form.cleaned_data.get('username')
            raw_password = form.cleaned_data.get('password1')
            user = authenticate(username=username, password=raw_password)
            print(f'User is: {user}')
            login(request, user)
            return redirect('/')

    else:
        form = UserCreationForm(request.POST)

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

def login_user(request):
    if request.method == 'POST':
        form = AuthenticationForm(request=request, data=request.POST)
        if form.is_valid():
            username = form.cleaned_data.get('username')
            raw_password = form.cleaned_data.get('password1')
            user = authenticate(username=username, password=raw_password)
            print(f'User is: {user}')
            print(f'username is: {username}')
            print(f'password is: {raw_password}')
            if user is not None:
                if user.is_active:
                    login(request, user)
                    print(f'You are now logged in as {username}')
                    messages.info(request, f"You are now logged in as {username}")
                    return redirect('/')
    else:
        form = AuthenticationForm()

    return render(request = request,
                    template_name = "login.html",
                    context={"form":form})

def logout_user(request):
    logout(request)
    return redirect('/')

Answer 1

raw_password = form.cleaned_data.get('password1')，这里您必须获得password本身而不是password1。

Django身份验证始终返回None
