__init __（）只需1个参数（给定2个），出了什么问题？

它基本上是我正在工作的网站的注册表单，它也不起作用，但我现在的主要问题是__init__错误。你能检查出错的地方和地点吗？

views.py：

from django.views.generic.edit import FormView
from django.views.decorators.csrf import csrf_protect
from django.core.context_processors import csrf
from django.contrib import auth
from authactions import forms
from authactions.forms import CreateForm

class SignupView(FormView):
    template_name = 'authactions/register.html'
    form_class = forms.CreateForm

def form_valid(self, form):
    profile = form.saveUser()
    user = authenticate(username=profile.user.username ,password=profile.user.password)
    auth.login(self.request,user)
    return HttpResponseRedirect('/profiles/')

forms.py：

from django import forms
from profiles.models import UserProfile
from django.contrib.auth.models import User
from django.contrib.auth.forms import UserCreationForm

class CreateForm(UserCreationForm):
    username = forms.CharField(required=True)
    password = forms.CharField(widget=forms.PasswordInput())
    password2 = forms.CharField(widget=forms.PasswordInput())
    email = forms.EmailField(required=True)

class Meta:
    model = UserProfile
    fields = ("username", "password", "password2", "email")

def saveUser(self):
    user = super(UserCreationForm, self).save()
    user.username = self.cleaned_data['username']
    user.password = self.cleaned_data['password']
    user.password2 = self.cleaned_data['password2']
    user.email = self.cleaned_data['email']
    if user.password != user.password2:
        raise forms.ValidationError("Mismatched password!")
    user.save()
    return user

class LoginForm(forms.Form):
    username = forms.CharField(required=True)
    password = forms.CharField(widget=forms.PasswordInput())

HTML：

<!DOCTYPE html>
<html>
<body>
        <div id = "signup_form">
            <form action="" method="POST">
            {% csrf_token %}
            {% if form.non_field_errors %}
                <ul>
                    {{ form.non_field_errors.as_ul }}
                </ul>
            {% endif %}
                <table>
                    <tr>
                        <td>
                            <h3>Personal Info</h3>
                        <input type = "text" name = "username" id = "username" class = "field" placeholder = "Username" required /><br />
                        <input type = "email" name = "email" id = "email" class = "field" placeholder = "Email" required />
                        <br />
                        <input type = "password" name = "password1" id = "password" class = "field" placeholder = "Password" required onkeyup = "check_length(1)"/><br />
                        <span>Password must be at least 7 characters long.</span><br />
                        <input type = "password" name = "password2" id = "password2" class = "field" placeholder = "Retype Password" required onkeyup = "check_password(1)" />
                    </td>
                </table>
                <input type = "submit" value = "Sign Up" id = "button" />
            </form>
        </div>
    </body>
</html>

您没有显示您的urls.py，但问题可能在于：在映射基于类的视图时需要使用as_view：

url('^register/$', SignupView.as_view(), name='register')

答案 1 :(得分：0)

我无法判断它是复制粘贴还是代码实际上是这样，但class Meta必须在CreateForm类中缩进。实际上，saveUser方法也必须缩进。
