python - 'list' 对象没有属性 'get' 打印问题

问题描述

我无法在表单操作中使用 get 方法，并且出现错误，因为它出现在标题中。

表格.py

class LoginForms(forms.Form):
username = forms.CharField(max_length=50,label="Kullanıcı Adınız")
password = forms.CharField(label = "Şifreniz", widget = forms.PasswordInput)

视图.py

def loginUser(request):

form = LoginForms(request.POST or None)

context = {
    "form":form
}
if form.is_valid():
    username = form.changed_data.get("username")
    password = form.changed_data.get("password")

    user = authenticate(username = username, password = password)
    if user is None:
        messages.info(request,"Kullanıcı Adı Yada Şifre Hatalı")
        return render(request,"login.html",context)

    messages.success(request,"Başarıyla Giriş Yaptınız!")
    login(request,user)
    return redirect(request,"index")

return render(request, "login.html", context)

错误：

解决方案

form.changed_data返回已更改的字段名称列表。您可以改用form.cleaned_data
