嘗試登錄時，Django沒有重新識別用戶密碼

當嘗試使用登錄和注冊創建一個簡單的網頁時，我遇到了 django 無法識別創建的用戶的問題。在views.py 中，我創建了一條簡單的訊息，如果用戶不存在，則顯示“密碼或電子郵件不正確”。我創建了一個用戶，并在我將密碼輸入登錄表單時確保密碼正確，但它仍然給我“密碼或電子郵件不正確”的訊息。如果它出錯并且我無法弄清楚它為什么不接受表單中的密碼/電子郵件，而不是像創建的用戶一樣重定向到主頁。

def home(request):
    return render(request, 'home.html')


def signup(request):

    if request.method == "POST":
        email = request.POST['email']
        password = request.POST['password']

         myuser = User(email=email)
         myuser.set_password(password)
         myuser.save()
    
        messages.success(request, "Your account has been successfully created ")

        return redirect('signin')

    return render(request, 'signup.html')

def signin(request):

    if request.method == "POST":
        email = request.POST['email']
        password = request.POST['password']

        user = authenticate(request, email = email, password = password)


        if user is not None: 
            login(request, user)
            email = user.email 
            messages.success(request, "Successfully Logged In")
            return redirect ('home')


        else:
            messages.info(request, "Email or Password is Incorrect")
            return render(request, 'signin.html')

    return render(request, 'signin.html')

您的用戶的狀態是什么。非活動用戶是其 is_active 欄位設定為 False 的用戶。默認后端ModelBackend和RemoteUserBackend禁止非活動用戶進行身份驗證。您沒有指定用戶狀態。所以也請檢查用戶狀態。

uj5u.com熱心網友回復：

您可以按以下方式改進這部分：

myuser = User(email=email, is_active=True)
myuser.set_password(password)
myuser.save()

要設定密碼，您必須使用set_password功能。
