如何允许用户在 Django 中更改自己的密码？

Django comes with a user authentication system. It handles user accounts, groups, permissions and cookie-based user sessions. This document explains how things work.

How to change Django passwords

See the Changing passwords section

1. Navigation to your project where manage.py file lies

2. $ python manage.py shell

3. type below scripts :

from django.contrib.auth.models import User
u = User.objects.get(username__exact='john')
u.set_password('new password')
u.save()

You can also use the simple manage.py command:

manage.py changepassword *username*

Just enter the new password twice.

from the Changing passwords section in the docs.

If you have the django.contrib.admin in your INSTALLED_APPS, you can visit: example.com/path-to-admin/password_change/ which will have a form to confirm your old password and enter the new password twice.

You can also just use the django.contrib.auth.views.password_change view in your URLconf. It uses a default form and template; supplying your own is optional.

urls.py:

urlpatterns = [
url(r'^accounts/', include('django.contrib.auth.urls')),

Template:

<a href="{% url 'password_change' %}">{% trans "Change password" %}</a>

Documented at: https://docs.djangoproject.com/en/1.9/topics/auth/default/#using-the-views

Very similar to @Ciro's answer, but more specific to the original question (without adding all the authentication views):

just add to urlpatterns in urls.py:

url('^change-password/$', auth_views.password_change, {'post_change_redirect': 'next_page'}, name='password_change'),

Note that post_change_redirect specifies the url to redirect after the password is changed.

Then, just add to your template:

<a href="{% url 'password_change' %}">Change Password</a>

Once the url pattern is added as shown in Ciro Santilli's answer, a quick way to allow users to change passwords is to give them "staff access" for the admin functions. If you don't add them to any groups or give them special permissions, they can still change their password by going to the example.com/admin page. The staff access lets them go to the page even if it is blank; in the upper right corner they can click "change password" and use the admin funtionality.

This is the command i used, just in case you are having problem in that throw AttributeError: Manager isn't available; 'auth.User' has been swapped for 'users.User'.

python manage.py shell -c "from django.contrib.auth import get_user_model;
User = get_user_model();
u = User.objects.get(username='admin');
u.set_password('password123');
u.save()"

Its without need to go to shell enter passwd and reenter passwd

 python manage.py changepassword <username>
or
/manage.py changepassword <username>

Using shell

python manage.py shell
from django.contrib.auth.models import User
users=User.objects.filter(email='<user_email>')
#you can user username or etc to get users query set
#you can also use get method to get users
user=users[0]
user.set_password('__enter passwd__')
user.save()
exit()

This tutorial shows how to do it with function based views:

View file:

from django.contrib import messages
from django.contrib.auth import update_session_auth_hash
from django.contrib.auth.forms import PasswordChangeForm
from django.shortcuts import render, redirect


def change_password(request):
if request.method == 'POST':
form = PasswordChangeForm(request.user, request.POST)
if form.is_valid():
user = form.save()
update_session_auth_hash(request, user)  # Important!
messages.success(request, 'Your password was successfully updated!')
return redirect('change_password')
else:
messages.error(request, 'Please correct the error below.')
else:
form = PasswordChangeForm(request.user)
return render(request, 'accounts/change_password.html', {
'form': form
})

Url file:

from django.conf.urls import url
from myproject.accounts import views


urlpatterns = [
url(r'^password/$', views.change_password, name='change_password'),
]

And finally, the template:

<form method="post">
{% csrf_token %}
\{\{ form }}
<button type="submit">Save changes</button>
</form>

Per the documentation, use:

from django.contrib.auth.hashers import makepassword

The main reason to do this is that Django uses hashed passwords to store in the database.

password=make_password(password,hasher='default')
obj=User.objects.filter(empid=emp_id).update(username=username,password=password)

I used this technique for the custom user model which is derived from the AbstractUser model. I am sorry if I technically misspelled the class and subclass, but the technique worked well.

Authentication is the one way and after that reset the password

from django.contrib.auth import authenticate
user = authenticate(username='username',password='passwd')
try:
if user is not None:
user.set_password('new password')
else:
print('user is not exist')
except:
print("do something here")
