python - Django-registration 重新发送带有新代码的激活邮件

Question

我正在使用 django-registration具有唯一的电子邮件地址，如果用户请求并且该帐户尚未激活，我希望能够将第二个激活表格发送到电子邮件。我找到了这个 link在 Stackoverflow 上，但我不明白我应该把例程放在哪里。我已将其放入我的应用程序的 views.py 中，但出现错误

global name 'RegistrationProfile' is not defined

这是因为 RegistrationProfile 是一个注册模型，但在发送激活表单时它不会在我的数据库中创建表/记录，所以我不明白如何访问它。

欢迎任何建议。

好的，这就是我想出的解决方案。它可能不是最漂亮的，但它对我有用。

这被添加到 views.py

from .forms import ResendActivationEmailForm
from django.core import signing
from django.contrib.sites.shortcuts import get_current_site
from django.template.loader import render_to_string


def resend_activation_email(request):

    email_body_template = 'registration/activation_email.txt'
    email_subject_template = 'registration/activation_email_subject.txt'

    if not request.user.is_anonymous():
        return HttpResponseRedirect('/')

    context = Context()

    form = None
    if request.method == 'POST':
        form = ResendActivationEmailForm(request.POST)
        if form.is_valid():
            email = form.cleaned_data["email"]
            users = User.objects.filter(email=email, is_active=0)

            if not users.count():
                form._errors["email"] = ["Account for email address is not registered or already activated."]

            REGISTRATION_SALT = getattr(settings, 'REGISTRATION_SALT', 'registration')
            for user in users:
                activation_key = signing.dumps(
                    obj=getattr(user, user.USERNAME_FIELD),
                    salt=REGISTRATION_SALT,
                    )
                context = {}
                context['activation_key'] = activation_key
                context['expiration_days'] = settings.ACCOUNT_ACTIVATION_DAYS
                context['site'] = get_current_site(request)

                subject = render_to_string(email_subject_template,
                                   context)
                # Force subject to a single line to avoid header-injection
                # issues.
                subject = ''.join(subject.splitlines())
                message = render_to_string(email_body_template,
                                           context)
                user.email_user(subject, message, settings.DEFAULT_FROM_EMAIL)
                return render(request, 'registration/resend_activation_email_done.html')

    if not form:
        form = ResendActivationEmailForm()

    context.update({"form" : form})
    return render(request, 'registration/resend_activation_email_form.html', context)

这被添加到forms.py

class ResendActivationEmailForm(forms.Form):
    email = forms.EmailField(required=True)

我在注册时有一个名为 resend_activation_email_form.html 的新模板，当重新发送电子邮件时使用它，但我使用完全相同的模板发送电子邮件。

我基于电子邮件，因为我使用的是唯一的电子邮件，但基于用户名可能更明智，因为 django-registration 将其定义为唯一。
