Django用户注册 - 通过电子邮件重置密码 [英] Django User Registration - Password Reset via email

问题描述

标题解释。

Django 1.5中是否有内置方法来处理用户密码重置？
ie通过电子邮件重置链接？

需要我的用户有一个忘记密码链接。

解决方案

是的。

您也可以在 forms.py

  class PassworResetForm（forms.Form）：
 error_messages = {
'unknown'：（That电子邮件地址没有关联的
用户帐户，您确定已注册？），
'不可用'：（与此电子邮件相关联的用户帐户
 
} 
 def clean_email（self）：

验证活动用户是否存在与给定的电子邮件地址

 UserModel = get_user_model（）
 email = self.cleaned_data [email] 
 self.users_cache = UserModel._default_manager.filter（email__iexact = email）
如果不是len（s elf.users_cache）
 raise forms.ValidationError（self.error_messages ['unknown']）
如果不是任何（user.is_active为self.users_cache中的用户）：
＃过滤的用户是活动的
 raise forms.ValidationError（self.error_messages ['unknown']）
如果有任何（（user.password == UNUSABLE_PASSWORD）
 for user in self.users_cache）：
 raise forms.ValidationError（self.error_messages ['unreable']）
 return email 
 
 def save（self，domain_override = None，
 subject_template_name ='registration / password_reset_subject .txt'，
 email_template_name ='registration / password_reset_email.html'，
 use_https = False，token_generator = default_token_generator，
 from_email =无，请求=无）：
 
生成一次性使用的链接以重置密码并发送给
用户。 

 from django.core.mail import send_mail 
 for user in self.users_cache：
 if not domain_override：
 current_site = get_current_site（request）
 site_name = current_site.name 
 domain = current_site.domain 
 else：
 site_name = domain = domain_override 
c = {
'email'：user.email，
'domain'：domain，
'site_name'：site_name，
'uid'：int_to_base36（user.pk），
'user'：user，
'token '：token_generator.make_token（user），
'protocol'：use_https和'https'或'http'，
} 
 subject = loader.render_to_string（subject_template_name，c）
 ＃电子邮件主题*不能*包含换行符
 subject =''.join（s ubject.splitlines（））
 email = loader.render_to_string（email_template_name，c）
 send_mail（subject，email，from_email，[user.email]）
  / pre> 
 
 
您必须生成用于发送给用户的html模板：
  {％autoescape off％} 
您收到此电子邮件是因为您在{{site_name}}上为您的用户帐户请求了密码重置。 
 
请转到以下页面并选择一个新密码：
 {％block reset_link％} 
 {{domain}} {％url'django.contrib.auth.views password_reset_confirm'uidb36 = uid token = token％} 
 {％endblock％} 
 
您的用户名，以防您忘记了：{{user.username}} 
 
感谢使用我们的网站！ 
 
 {{site_name}}小组。 
 
 {％endautoescape％} 
  
并将此网址添加到 urls.py  
 （r'^ accounts / password / reset / $'，'django.contrib。 auth.views.password_reset'，
 {'post_reset_redirect'：'/ accounts / password / reset / done /'}），
（r'^ accounts / password / reset / done / $' django.contrib.auth.views.password_reset_done'），
（r'^ accounts / password / reset /（？P  {'post_reset_redirect'：'/ accounts / password / done /'}），
（r'^ accounts /密码/完成/ $'，'django.contrib.auth.views.password_reset_complete'），
  
 Make每个网址的模板
 
As title explains.

Is there a built in method within Django 1.5 that handles user password resets?
i.e. Via an email reset link?

Need my users to have a "Forgot Password" link.
解决方案
Yes there is.

You can use this form too in your forms.py
class PassworResetForm(forms.Form):
    error_messages = {
        'unknown': ("That email address doesn't have an associated "
                     "user account. Are you sure you've registered?"),
        'unusable': ("The user account associated with this email "
                      "address cannot reset the password."),
        }
    def clean_email(self):
        """
        Validates that an active user exists with the given email address.
        """
        UserModel = get_user_model()
        email = self.cleaned_data["email"]
        self.users_cache = UserModel._default_manager.filter(email__iexact=email)
        if not len(self.users_cache):
            raise forms.ValidationError(self.error_messages['unknown'])
        if not any(user.is_active for user in self.users_cache):
            # none of the filtered users are active
            raise forms.ValidationError(self.error_messages['unknown'])
        if any((user.password == UNUSABLE_PASSWORD)
            for user in self.users_cache):
            raise forms.ValidationError(self.error_messages['unusable'])
        return email

    def save(self, domain_override=None,
             subject_template_name='registration/password_reset_subject.txt',
             email_template_name='registration/password_reset_email.html',
             use_https=False, token_generator=default_token_generator,
             from_email=None, request=None):
        """
        Generates a one-use only link for resetting password and sends to the
        user.
        """
        from django.core.mail import send_mail
        for user in self.users_cache:
            if not domain_override:
                current_site = get_current_site(request)
                site_name = current_site.name
                domain = current_site.domain
            else:
                site_name = domain = domain_override
            c = {
                'email': user.email,
                'domain': domain,
                'site_name': site_name,
                'uid': int_to_base36(user.pk),
                'user': user,
                'token': token_generator.make_token(user),
                'protocol': use_https and 'https' or 'http',
                }
            subject = loader.render_to_string(subject_template_name, c)
            # Email subject *must not* contain newlines
            subject = ''.join(subject.splitlines())
            email = loader.render_to_string(email_template_name, c)
            send_mail(subject, email, from_email, [user.email])
You must generate the html template for send to the user:
{% 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 %}
       {{ 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 %}
And add this url to the urls.py
(r'^accounts/password/reset/$', 'django.contrib.auth.views.password_reset',
     {'post_reset_redirect' : '/accounts/password/reset/done/'}),
    (r'^accounts/password/reset/done/$', 'django.contrib.auth.views.password_reset_done'),
    (r'^accounts/password/reset/(?P<uidb36>[0-9A-Za-z]+)-(?P<token>.+)/$', 'django.contrib.auth.views.password_reset_confirm',
     {'post_reset_redirect' : '/accounts/password/done/'}),
    (r'^accounts/password/done/$', 'django.contrib.auth.views.password_reset_complete'),
Make a template for each url
