Python Django用户可以'；t登录

我做了一个自定义的UserCreationForm。我可以注册，但注册之后我就不能登录我的web应用了。我只能以超级用户身份登录。我导入了LoginView（），但当我尝试登录时，它告诉我“请输入正确的用户名和密码。请注意，这两个字段可能区分大小写。”

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:
                print('found it')
                profile.profile_pic = request.FILES['profile_pic']

            login(request, user, backend='django.contrib.auth.backends.ModelBackend')
            return redirect('../')
        else:
            print(user_form.errors,profile_form.errors)
    else:

您将如何登录？给我们看代码，我没有任何代码。我在我的url.py中导入了登录视图，然后将其呈现到模板中。我在帖子中添加了login.html。删除这一行：

user.set\u password（user.password）

。这会导致双重哈希。您将如何登录？给我们看代码，我没有任何代码。我在我的url.py中导入了登录视图，然后将其呈现到模板中。我在帖子中添加了login.html。删除这一行：
