Question

from django import forms
from allauth.account.forms import (LoginForm, ChangePasswordForm,
                               ResetPasswordForm, SetPasswordForm, ResetPasswordKeyForm)  
from django.contrib.auth import get_user_model  
from crispy_forms.helper import FormHelper  
from crispy_forms.layout import Layout, Div, Submit, HTML, Button, Row, Field  
from crispy_forms.bootstrap import AppendedText, PrependedText, FormActions  
from django.core.urlresolvers import reverse  


class MySignupForm(forms.Form):
    class Meta:
        model = get_user_model()
        fields = ['email', 'first_name', 'last_name']

    def __init__(self, *args, **kwargs):
        super(MySignupForm, self).__init__(*args, **kwargs)
        self.helper = FormHelper()
        self.fields["email"].widget.input_type = "email"  # ugly hack
        self.helper.form_method = "POST"
        self.helper.form_action = "account_signup"
        self.helper.form_id = "signup_form"
        self.helper.form_class = "signup"
        self.helper.layout = Layout(
            Field('email', placeholder="Enter Email", autofocus=""),
            Field('first_name', placeholder="Enter First Name"),
            Field('last_name', placeholder="Enter Last Name"),
            Field('password1', placeholder="Enter Password"),
            Field('password2', placeholder="Re-enter Password"),
        Submit('sign_up', 'Sign up', css_class="btn-warning"),
        )

    def signup(self, request, user):
        pass


class MyLoginForm(LoginForm):
    remember_me = forms.BooleanField(required=False, initial=False)

    def __init__(self, *args, **kwargs):
        super(MyLoginForm, self).__init__(*args, **kwargs)


class MyPasswordChangeForm(ChangePasswordForm):

    def __init__(self, *args, **kwargs):
        super(MyPasswordChangeForm, self).__init__(*args, **kwargs)

我的app.forms.py文件中有这样的结构，我在这里导入以表单LoginForm ResetPasswordForm等构建的allauth，并在同一个文件中定义自定义注册类。

自定义注册类的钩子： ACCOUNT_SIGNUP_FORM_CLASS ='allauth_core.forms.MySignupForm'

我认为我遇到了循环导入问题，但不确定原因？

文件“/Users/rmahamuni/.virtualenvs/todo/lib/python2.7/site-packages/allauth/urls.py”，第8行，in urlpatterns = [url（'^'，include（'allauth.account.urls'））] 文件“/Users/rmahamuni/.virtualenvs/todo/lib/python2.7/site-packages/django/conf/urls/init.py”，第52行，包括 urlconf_module = import_module（urlconf_module）在import_module中输入文件“/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/importlib/init.py”，第37行导入（名称）文件“/Users/rmahamuni/.virtualenvs/todo/lib/python2.7/site-packages/allauth/account/urls.py”，第4行，in 来自。导入视图文件“/Users/rmahamuni/.virtualenvs/todo/lib/python2.7/site-packages/allauth/account/views.py”，第19行，in from .forms import（文件“/Users/rmahamuni/.virtualenvs/todo/lib/python2.7/site-packages/allauth/account/forms.py”，第206行， class BaseSignupForm（_base_signup_form_class（））：在_base_signup_form_class中输入文件“/Users/rmahamuni/.virtualenvs/todo/lib/python2.7/site-packages/allauth/account/forms.py”，第188行 '“％s”'％（fc_module，e）） django.core.exceptions.ImproperlyConfigured：导入表单类allauth_core.forms时出错：“无法导入名称ChangePasswordForm”

如果我将自定义注册表单保存在单独的文件中，那么我就不会遇到这个问题。

我尝试切换已安装的应用阵容

'allauth',
'allauth.account',
'allauth.socialaccount',
'allauth_core',  <-- app where form is located.

我在这里缺少什么？有人可以指导我吗？感谢

这是因为allauth尝试导入您在其settings.py account/forms.py中指定为注册表单的给定模块/类。（见forms.py#L186 @ github）

当您通过导入ChangePasswordForm的{{1}}覆盖settings.py中的allauth等其他表单时，会发生循环导入，因为allauth已经在其中导入了account/forms.py forms.py

要避免这种情况，只需将您的单身表格移至单独的forms.py并相应更改设置即可。它会工作。

保持自定义sign_up类并在相同的forms.py文件中导入allauth表单导致导入错误
