Question

I am using contrib auth reset_password in django and I get an error when I click the link it sends me.

Here is my urls.py:

url(r'^password_reset/$', views.reset, name='password-reset'),
url(r'^reset/(?P<uidb64>[0-9A-Za-z_\-]+)/(?P<token>[0-9A-Za-z]{1,13}-[0-9A-Za-z]{1,20})/$',
    views.reset_confirm, name='password-reset-confirm'),

and my views.py:

def reset_confirm(request, uidb64=None, token=None):
    return password_reset_confirm(request, template_name='registration/reset_confirm.html',
        uidb64=uidb64, token=token, post_reset_redirect=reverse('dashboard-login'))


def reset(request):
    return password_reset(request, template_name='registration/reset.html',
        email_template_name='registration/reset_email.html',
        subject_template_name='registration/reset_subject.txt',
        post_reset_redirect=reverse('dashboard-login'))

and the email template:

Someone asked for password reset for email {{ email }}. Follow the link below:
https://www.websitename.com{% url 'password-reset-confirm' uidb64=uid token=token %}

yes it isn't "websitename.com" in the actual template. and my reset page templates:

<div class="reset-page">
        <h3 class="reset-header">{% blocktrans %}Reset Password - Step 1 of 2{% endblocktrans %}</h3>
        <form class="login-form" action="{% url 'password-reset' %}" method="post"> 
            <div class='form'>                
                {% csrf_token %}               
                <input id="id_email" name="email" type="text" class="text-login" placeholder="Email" />
                <input type="submit" class="submit-login" style="margin-top: 30px;" value="{% trans 'Submit' %}" />
            </div>
        </form>
        <p class="reset-info">{% blocktrans %}Enter your email address to receive a password change link.{% endblocktrans %}</p>
</div>  

and the template that isn't showing, the confirm:

<div class="reset-page">
        <h3 class="reset-header">{% blocktrans %}Reset Password - Step 2 of 2{% endblocktrans %}</h3>
        <form class="login-form" action="{% url 'password-reset-confirm' uidb64=uidb64 token=token %}" method="post">
            <div class='form'>
                {% if validlink %}
                    {% csrf_token %}
                    <input id="id_new_password1" name="new_password1" type="text" class="text-login" placeholder="Password" />
                    <input id="id_new_password2" name="new_password2" type="text" class="text-login" placeholder="Confirm Password" />
                    <input type="submit" class="submit-login" value="{% trans 'Submit' %}" />
                {% else %}
                    <p class="reset-error">{% blocktrans %}Error: This reset link is no longer valid!{% endblocktrans %}</p>
                {% endif %}
                {% if error_messages %}
                    <p class="reset-error">Error: {{ error_messages }}</p>
                {% endif %}                    
            </div>
        </form>
        <p class="reset-info">{% blocktrans %}Enter your new password, twice.{% endblocktrans %}</p>
</div>

It works up to the email's link. I enter my email on /password_reset/ and it sends the email, but the link gives me that error instead of taking me to the page where I enter 2 new passwords. The error seems to occur in the url tag in the confirm template.

EDIT:

Here is django.contrib.auth.views.password_reset_confirm() which is part of where the error comes from:

@sensitive_post_parameters()
@never_cache

                           set_password_form=SetPasswordForm,
                           post_reset_redirect=None,
                           current_app=None, extra_context=None):
    """
    View that checks the hash in a password reset link and presents a
    form for entering a new password.
    """
    UserModel = get_user_model()
    assert uidb64 is not None and token is not None  # checked by URLconf
    if post_reset_redirect is None:
        post_reset_redirect = reverse('password_reset_complete')
    else:
        post_reset_redirect = resolve_url(post_reset_redirect)
    try:
        # urlsafe_base64_decode() decodes to bytestring on Python 3
        uid = force_text(urlsafe_base64_decode(uidb64))
        user = UserModel._default_manager.get(pk=uid)
    except (TypeError, ValueError, OverflowError, UserModel.DoesNotExist):
        user = None

    if user is not None and token_generator.check_token(user, token):
        validlink = True
        title = _('Enter new password')
        if request.method == 'POST':
            form = set_password_form(user, request.POST)
            if form.is_valid():
                form.save()
                return HttpResponseRedirect(post_reset_redirect)
        else:
            form = set_password_form(user)
    else:
        validlink = False
        form = None
        title = _('Password reset unsuccessful')
    context = {
        'form': form,
        'title': title,
        'validlink': validlink,
    }
    if extra_context is not None:
        context.update(extra_context)

    if current_app is not None:
        request.current_app = current_app

    return TemplateResponse(request, template_name, context)

I realized that in the confirm template it wasn't getting the arguments uidb64 and token. So I added them but now I am getting the error at the top which is slightly different. The arguments seem to be empty. How can I get the values of uidb64 and token so I can pass them into the url?

Answer 1

The solution was to set form action in the confirm template to

action=""

oddly enough.
