Question

我是django的新手。在这里，我想为我的django app创建登录。当我尝试创建用户帐户时，它会出现以下错误

FieldError at /signup/ Cannot resolve keyword 'mobile' into field Choices are: date_joined, email, first_name, groups, id, is_active, is_staff, is_superuser, last_login, last_name, logentry, password, user_permissions, username, userregform

创建用户帐户时，我想添加用户名，电子邮件，手机号码，密码和组织名称。如果电子邮件或手机尚未存在，则应提供错误消息

这是我的代码

forms.py

User=get_user_model()

class UserLoginForm(forms.Form):
    email=forms.EmailField(label='Email address')
    password = forms.CharField(label='Password',
                          widget=forms.PasswordInput())
    def clean(self,*args,**kwargs):
        email=self.cleaned_data.get("email")
        password=self.cleaned_data.get("password")
        if email and password:
            user=authenticate(email=email,password=password)
            if not user:
                raise forms.ValidationError("This email id is not registered")
            if not user.check_password(password):
                raise forms.ValidationError("Incorrect password")
            return super(UserLoginForm,self).clean(*args,**kwargs)
class RegistrationForm(forms.ModelForm):
    username= forms.CharField(label='Username')
    email = forms.EmailField(label='Email address')
    mobile =forms.CharField(label='Mobile No')
    password = forms.CharField(label='Password')
    org_name = forms.CharField(label='Organisation Name')

    class Meta:
        model = User
        fields = ['username', 'email', 'mobile', 'password','org_name']
    def clean_email(self):
        email = self.cleaned_data.get('email')
        check_duplicate_email = User.objects.filter (email=email).exists()
        if check_duplicate_email:
            raise forms.ValidationError(
            "This email id is already registered"
            )
        return email
    def clean_mobile(self):
        mobile=self.cleaned_data.get('mobile')
        check_duplicate_mobile=User.objects.filter(mobile=mobile).exists()
        if check_duplicate_mobile:
            raise forms.ValidationError(
              "This mobile no is already registered"
            )
        return mobile

    email=models.OneToOneField(User,unique=True)
    mobile =models.CharField(max_length=10)
    org_name = models.CharField(max_length=254)

    if form.is_valid():

    if request.method=="POST":

    {% block title %}Registration{% endblock %}
    {% block content %}
        <h1>Registration</h1>
        {% if form.errors %}
        <h1>Error</h1>
        {% endif %}

        <form method="post" action="{% url 'userRegistration:signup' %}"">{% csrf_token %}

您的RegistrationForm使用User模型。我不知道它在哪里。（也许django默认User模型？）但是你不能使用其他模型中的字段。（在这种情况下，UserRegForm）。

如果您在注册时添加一些字段，则必须在注册完成后添加。

只需从表单中删除clean_mobile，然后将其添加到signup视图即可。如下所示（这只是一个例子。你必须按照自己的方式进行自定义

def signup(request):
    title="Signup"
    if request.method=="POST":
        form = RegistrationForm(request.POST)
        print form.is_valid() #print False
        if form.is_valid():
            user=form.save(commit=False)
            email = form.cleaned_data.get("email")
            password = form.cleaned_data.get("password")
            user=set_password(password)
            user.save()
            # and save UserRegForm model here
            # and call clean_mobile here
            mobile = clean_mobile(form.cleaned_data.get('mobile')
            UserRegForm.create(
                email=user, 
                mobile=mobile
                ...
            )
            new_user = authenticate(email=user.email, password=password)
            login(request, new_user)
            return redirect("userRegistration/a.html")
    else:
        form=RegistrationForm()
    return render(request, "userRegistration/signup.html", {"form":form,"title":title})
