Question

我正在尝试使用PasswordResetForm内置函数。

由于我想拥有自定义表单字段，我编写了自己的表单：

class FpasswordForm(PasswordResetForm):
    email = forms.CharField(max_length=30, widget=forms.TextInput(attrs={'autofocus': 'autofocus'}))
    class Meta:
        model = User
        fields = ("email")
    def clean_email(self):
        email = self.cleaned_data['email']
        if function_checkemaildomain(email) == False:
            raise forms.ValidationError("Untrusted email domain")
        elif function_checkemailstructure(email)==False:
            raise forms.ValidationError("This is not an email adress.")

        return email

这是我在views.py中的观点

@cache_control(max_age=0, no_cache=True, no_store=True, must_revalidate=True)
def fpassword(request):
    form = FpasswordForm(request.POST or None)
    if form.is_valid():
        email = form.cleaned_data["email"]
        if function_checkemail(email):
            form.save(from_email='blabla@blabla.com', email_template_name='registration/password_reset_email.html')
            print "EMAIL SENT"
        else:
            print "UNKNOWN EMAIL ADRESS"

我的电子邮件模板是：

{% autoescape off %}
You're receiving this e-mail because you requested a password reset for your user account at {{ site_name }}.

Please go to the following page and choose a new password:
{% block reset_link %}
{{ protocol }}://{{ domain }}{% url "django.contrib.auth.views.password_reset_confirm" uidb36=uid token=token %}
{% endblock %}

Your username, in case you've forgotten: {{ user.username }}

Thanks for using our site!

The {{ site_name }} team.

{% endautoescape %}

问题是我遇到了'NoneType' object has no attribute 'get_host'错误...追溯日志告诉我在current_site = RequestSite(request)中，请求是None。也许我在views.py中的save()中添加了其他内容？

当我在表单和内置视图中使用以下方法而没有自定义字段时，一切正常：http://garmoncheg.blogspot.com.au/2012/07/django-resetting-passwords-with.html

所以你得到了这个错误，因为它试图在一个设置为None的实例上调用一个方法。这是您应该使用的正确视图：

@cache_control(max_age=0, no_cache=True, no_store=True, must_revalidate=True)
def fpassword(request):
    form = FpasswordForm(request.POST or None)
    if form.is_valid():
        email = form.cleaned_data["email"]
        if function_checkemail(email):
            form.save(from_email='blabla@blabla.com', email_template_name='registration/password_reset_email.html', request=request)
            print "EMAIL SENT"
        else:
            print "UNKNOWN EMAIL ADRESS"

另一种选择是启用Django Sites Framework。然后您不必传递请求，因为get_current_site将返回站点当前实例。这是该逻辑的link。
