如何让用户在Django中更改自己的密码？

from django.contrib.auth import views as auth_views

urlpatterns = [
    # ...
    path('password_change/', auth_views.PasswordChangeView.as_view(), name='password_change'),
    path('password_change/done/', auth_views.PasswordChangeDoneView.as_view(), name='password_change_done'),
    # ...
]

{% extends 'base.html' %}

{% block content %}
  <h2>Change password</h2>
  <form method="post">
    {% csrf_token %}
    {{ form.as_p }}
   <button type="submit">Change password</button>
  </form>
{% endblock %}

from django.contrib.auth import update_session_auth_hash
from django.contrib.auth.forms import PasswordChangeForm
from django.contrib.auth.views import PasswordChangeView
from django.shortcuts import render

class MyPasswordChangeView(PasswordChangeView):
    form_class = PasswordChangeForm
    success_url = '/password_change/done/'
    template_name = 'registration/password_change_form.html'

    def form_valid(self, form):
        form.save()
        update_session_auth_hash(self.request, form.user)
        return super().form_valid(form)

from . import views as my_views

urlpatterns = [
    # ...
    path('password_change/', my_views.MyPasswordChangeView.as_view(), name='password_change'),
    path('password_change/done/', auth_views.PasswordChangeDoneView.as_view(), name='password_change_done'),
    # ...
]
