1.定位自帶密碼設定函式/usr/local/python3/lib/python3.6/site-packages/django/contrib/auth/views.py

@sensitive_post_parameters()
@csrf_protect
@login_required
@deprecate_current_app
def password_change(request,
                    template_name='registration/password_change_form.html',
                    post_change_redirect
 
=None,
                    password_change_form=PasswordChangeForm,
                    extra_context=None):
    warnings.warn("The password_change() view is superseded by the "
                  "class-based PasswordChangeView().",
                  RemovedInDjango21Warning, stacklevel=2)
    if post_change_redirect is
 
 None:
        post_change_redirect = reverse('password_change_done')
    else:
        post_change_redirect = resolve_url(post_change_redirect)
    if request.method == "POST":
        form = password_change_form(user=request.user, data=request.POST)
        if form.is_valid():
            form.save()
            
 
# Updating the password logs out all other sessions for the user
            # except the current one.
            update_session_auth_hash(request, form.user)
            return HttpResponseRedirect(post_change_redirect)
    else:
        form = password_change_form(user=request.user)
    context = {
        'form': form,
        'title': _('Password change'),
    }
    if extra_context is not None:
        context.update(extra_context)

    return TemplateResponse(request, template_name, context)

@login_required
@deprecate_current_app
def password_change_done(request,
                         template_name='registration/password_change_done.html',
                         extra_context=None):
    warnings.warn("The password_change_done() view is superseded by the "
                  "class-based PasswordChangeDoneView().",
                  RemovedInDjango21Warning, stacklevel=2)
    context = {
        'title': _('Password change successful'),
    }
    if extra_context is not None:
        context.update(extra_context)

    return TemplateResponse(request, template_name, context)

2. 編輯 account/urls.py 設定password_change url

from django.conf.urls import url 
from . import views
from django.contrib.auth import views as auth_view

urlpatterns = [ 
    url(r'^login$',views.user_login,name="user_login"),
    url(r'^new_login$',auth_view.login,{ "template_name":"account/registration/login.html"},name="new_user_login"),
    url(r'^logout/$',auth_view.logout,{ "template_name":"account/logout.html"},name="user_logout"),
    url(r'^register/$',views.register,name="user_register"),
    url(r'^password_change/$',auth_view.password_change,{"post_change_redirect":"/account/password_change_done/","template_name":"account/password_change_form.html"},name="password_change"),
    url(r'^password_change_done/$',auth_view.password_change_done,{"template_name":"account/password_change_done.html"},name="password_change_done"),
]

3.新建並編輯templates/account/password_change_form.html 和templates/account/password_change_done.html

templates/account/password_change_form.html 內容如下：(PS:其實用的是 django自帶的 /usr/local/python3/lib/python3.6/site-packages/django/contrib/admin/templates/registration ，書裡面提供的前端，不會提示密碼不合理的地方)

{% extends "admin/base_site.html" %}
{% load i18n static %}
{% block extrastyle %}{{ block.super }}<link rel="stylesheet" type="text/css" href="{% static "admin/css/forms.css" %}" />{% endblock %}
{% block userlinks %}{% url 'django-admindocs-docroot' as docsroot %}{% if docsroot %}<a href="{{ docsroot }}">{% trans 'Documentation' %}</a> / {% endif %} {% trans 'Change password' %} / <a href="{% url 'admin:logout' %}">{% trans 'Log out' %}</a>{% endblock %}
{% block breadcrumbs %}
<div class="breadcrumbs">
<a href="{% url 'admin:index' %}">{% trans 'Home' %}</a>
&rsaquo; {% trans 'Password change' %}
</div>
{% endblock %}

{% block title %}{{ title }}{% endblock %}
{% block content_title %}<h1>{{ title }}</h1>{% endblock %}

{% block content %}<div id="content-main">

<form method="post">{% csrf_token %}
<div>
{% if form.errors %}
    <p class="errornote">
    {% if form.errors.items|length == 1 %}{% trans "Please correct the error below." %}{% else %}{% trans "Please correct the errors below." %}{% endif %}
    </p>
{% endif %}


<p>{% trans "Please enter your old password, for security's sake, and then enter your new password twice so we can verify you typed it in correctly." %}</p>

<fieldset class="module aligned wide">

<div class="form-row">
    {{ form.old_password.errors }}
    {{ form.old_password.label_tag }} {{ form.old_password }}
</div>

<div class="form-row">
    {{ form.new_password1.errors }}
    {{ form.new_password1.label_tag }} {{ form.new_password1 }}
    {% if form.new_password1.help_text %}
    <div class="help">{{ form.new_password1.help_text|safe }}</div>
    {% endif %}
</div>

<div class="form-row">
{{ form.new_password2.errors }}
    {{ form.new_password2.label_tag }} {{ form.new_password2 }}
    {% if form.new_password2.help_text %}
    <div class="help">{{ form.new_password2.help_text|safe }}</div>
    {% endif %}
</div>

</fieldset>

<div class="submit-row">
    <input type="submit" value="{% trans 'Change my password' %}" class="default" />
</div>

</div>
</form></div>

{% endblock %}

templates/account/password_change_done.html 內容如下：

{% extends "base.html" %}
{% block title%}password change done {% endblock %}
{% block content%}
    <div class="text-center row vertical-md-sm">
        <p>your password was changed</p>
    </div>
{% endblock %}

4.瀏覽器開啟http://192.168.56.101:8800/account/password_change/

確認老密碼，填寫新密碼後，點選 change my password,自動跳到完成介面
