如何修复我的 django 表单没有 cleaned_data 属性的错误?

How do I fix the error of my django form not having cleaned_data attribute?

我有这个表格:

class RegisterForm(UserCreationForm):
    email = forms.EmailField()

    class Meta:
        model = User
        fields = ["username", "email", "password1",
                  "pass"]

这个视图:

def register(req):
    if req.method == 'POST':
        form = RegisterForm(req.POST)
        print('yaml')
        if form.is_valid():
            form.save()
        return redirect("/home")
    else:
        form = RegisterForm()
        form.save()
        return render(req, "users/register.html", {"form":form})

但是当我访问 url

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include("main.urls")),
    path('register/', userViews.register, name="register"),
    path('', include("django.contrib.auth.urls")),
]

我不断收到此错误:

Internal Server Error: /register/
....
AttributeError: 'RegisterForm' object has no attribute 'cleaned_data'

拜托,我需要一些帮助。

在 GET 请求的情况下删除 form.save():您只能保存一个对象,以防它是有界且有效的,因此:

def register(request):
    if request.method == 'POST':
        form = RegisterForm(request.POST, request.FILES)
        if form.is_valid():
            form.save()
            # only redirect when the POST is <strong>successful</strong>
            return redirect('home')  # 🖘 use the name of a view
    else:
        form = RegisterForm()  # <strong>no</strong> form.save()
    return render(request, 'users/register.html', {'form': form})

首先,pass 是内置 User 模型中没有的字段,有两个字段与密码相关,分别是 password1password2,除非并且直到你没有在原来的 django 代码中改变它。

不需要重定向,else条件下请去掉form.save()
