Changing password in Django Admin

Question

I recently created the admin.py based in the Django Project Document:

https://docs.djangoproject.com/en/dev/topics/auth/customizing/#django.contrib.auth.models.AbstractBaseUser

But I really missed the functionality that allow the administrator the possibility to change the users passwords. How is possible to add this functionality? I just copied and pasted the code the is in the link above.

from django import forms
from django.contrib import admin
from django.contrib.auth.models import Group
from django.contrib.auth.admin import UserAdmin
from django.contrib.auth.forms import ReadOnlyPasswordHashField

from customauth.models import MyUser


class UserCreationForm(forms.ModelForm):
    """A form for creating new users. Includes all the required
    fields, plus a repeated password."""
    password1 = forms.CharField(label='Password', widget=forms.PasswordInput)
    password2 = forms.CharField(label='Password confirmation', widget=forms.PasswordInput)

    class Meta:
        model = MyUser
        fields = ('email', 'date_of_birth')

    def clean_password2(self):
        # Check that the two password entries match
        password1 = self.cleaned_data.get("password1")
        password2 = self.cleaned_data.get("password2")
        if password1 and password2 and password1 != password2:
            raise forms.ValidationError("Passwords don't match")
        return password2

    def save(self, commit=True):
        # Save the provided password in hashed format
        user = super(UserCreationForm, self).save(commit=False)
        user.set_password(self.cleaned_data["password1"])
        if commit:
            user.save()
        return user


class UserChangeForm(forms.ModelForm):
    """A form for updating users. Includes all the fields on
    the user, but replaces the password field with admin's
    password hash display field.
    """
    password = ReadOnlyPasswordHashField()

    class Meta:
        model = MyUser

    def clean_password(self):
        # Regardless of what the user provides, return the initial value.
        # This is done here, rather than on the field, because the
        # field does not have access to the initial value
        return self.initial["password"]


class MyUserAdmin(UserAdmin):
    # The forms to add and change user instances
    form = UserChangeForm
    add_form = UserCreationForm

    # The fields to be used in displaying the User model.
    # These override the definitions on the base UserAdmin
    # that reference specific fields on auth.User.
    list_display = ('email', 'date_of_birth', 'is_admin')
    list_filter = ('is_admin',)
    fieldsets = (
        (None, {'fields': ('email', 'password')}),
        ('Personal info', {'fields': ('date_of_birth',)}),
        ('Permissions', {'fields': ('is_admin',)}),
        ('Important dates', {'fields': ('last_login',)}),
    )
    add_fieldsets = (
        (None, {
            'classes': ('wide',),
            'fields': ('email', 'date_of_birth', 'password1', 'password2')}
        ),
    )
    search_fields = ('email',)
    ordering = ('email',)
    filter_horizontal = ()

# Now register the new UserAdmin...
admin.site.register(MyUser, MyUserAdmin)
# ... and, since we're not using Django's builtin permissions,
# unregister the Group model from admin.
admin.site.unregister(Group)

[UPDATE - Added Information] I changed the following information but I still seeing just the password (crypted) in a read-only field. How is possible to add a link to change the password?

fieldsets = (
    ('Permissions', {'fields': ('is_active', 'is_admin','password')}),
)
add_fieldsets = (
    (None, {
        'classes': ('wide',),
        'fields': ('email', 'password')}
    ),
)

Put this in your UserChangeForm:

password = ReadOnlyPasswordHashField(label= ("Password"),
        help_text= ("Raw passwords are not stored, so there is no way to see "
                    "this user's password, but you can change the password "
                    "using <a href=\"password/\">this form</a>."))

Code borrowed from here: http://hdknr.github.com/docs/django/modules/django/contrib/auth/forms.html

Answer 2

password = ReadOnlyPasswordHashField(label= ("Password"),
        help_text= ("Raw passwords are not stored, so there is no way to see "
                    "this user's password, but you can change the password "
                    "using <a href=\"../password/\">this form</a>."))

There is change in the href, for previous versions of django you can use

<a href=\"/password/\">this form</a>.

For django 1.9+ <a href=\"../password/\">this form</a>

Answer 3

I added this method to my UserAdmin class:

def save_model(self, request, obj, form, change):
    # Override this to set the password to the value in the field if it's
    # changed.
    if obj.pk:
        orig_obj = models.User.objects.get(pk=obj.pk)
        if obj.password != orig_obj.password:
            obj.set_password(obj.password)
    else:
        obj.set_password(obj.password)
    obj.save()

You can the show the password field normally, but admins will only see the hashed password. If they alter it, the new value is then hashed and save.

This adds a single query to each time you save a user via the admin. It should generally not be an issue, since most systems don't have admins intensively editing users.

Answer 4

('Permissions', {'fields': ('is_active', 'is_superuser',)}),

Answer 5

For a django version independent solution you can reverse the url in the UserChangeForm.__init__ with something like:

from django.core.urlresolvers import reverse

class UserChangeForm(forms.ModelForm):
    password = ReadOnlyPasswordHashField()
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.fields['password'].help_text = (
            "Raw passwords are not stored, so there is no way to see "
            "this user's password, but you can <a href=\"%s\"> "
            "<strong>Change the Password</strong> using this form</a>."
        ) % reverse_lazy('admin:auth_user_password_change', args=[self.instance.id])
