Admin interface no longer working after server update

[85oppilif]

Hello,
my shared server was recently upgraded. I am running an old version of django (3.0.4). After upgrading the venv, the django site started working again, except for one part, the admin interface.
The admin page is Django’s standard page. The code has never been altered for years.

From the browser I get an error 500 when I try to login.
From the debug log I can see this

Can anyone help me solve this problem?

I am running an old version of django (3.0.4).

Use a version of Python compatible with your version of Django.

See Django 3.0 release notes | Django documentation | Django and FAQ: Installation | Django documentation | Django

[85oppilif]

Thanks for the advice, many warnings went away after downgrading to python 3.7 but i still get the 500 error

This is the trackback from debug

@85oppilif

django.urls.exceptions.NoReverseMatch: Reverse for 'login' not found. 'login' is not a valid view function or pattern name.

That seems pretty explicit to me. It’s telling you that you don’t have a url defined with the name login.

What are the specific circumstances under which you’re getting this error? (What page are you currently on? Are you getting this from a link or are you entering the url directly? Are you getting it when trying to go to a page, or when you’re submitting something from a form on a page?)

[85oppilif]

I’m getting this when I click the “login” button on the /admin page (address typed in manually).

The page is defined as follows in urls.py

path('admin/', admin.site.urls),

[KenWhitesell]

Do you have a LOGIN_URL in your settings.py?

Please show your INSTALLED_APPS and MIDDLEWARE settings.

[85oppilif]

I don’t have a LOGIN_URL in settings.py.

INSTALLED_APPS and MIDDLEWARE are as follows:

INSTALLED_APPS = [
    'cammini',
    'friends',
    'books',
    'links',
    'imagekit',
    'django_filters',
    'django.contrib.gis',
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
]

MIDDLEWARE = [
    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
]

[KenWhitesell]

Have you created a template in any of your apps to override the system-provided login template?

Also, what is your TEMPLATES setting?

[85oppilif]

The only login form is in the admin page and should be the system-provided one.

This is my templates setting

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': ['camminiverticali_2_0/templates',],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]

[KenWhitesell]

@85oppilif

The only login form is in the admin page and should be the system-provided one.

Check to see if you have any file named login.html anywhere within your project or anywhere within the third-party libraries being used. If you find any, post their complete location here.

Check to see if you have done any configuration of the AdminSite. If so, post those configuration settings.

The various objects from the apps are managed through the admin interface

#from django.contrib.gis import OSMGeoAdmin
from django.utils.safestring import mark_safe
# Register your models here.
from .models import *
from .forms import CamminoAdminForm
from imagekit.admin import AdminThumbnail



@admin.register(Peak)
class PeakAdmin(OSMGeoAdmin):
    default_lon = 1009310
    default_lat = 5790301
    default_zoom = 8
    list_display = ('name', 'location')


#admin.site.register(Route)



class CamminoImageAdmin(admin.ModelAdmin):
    admin_photo = AdminThumbnail(image_field='thumbnail')
    list_display = [
        'admin_photo',
        'image',
        'caption',
        'cammino'
    ]
    #readonly_fields = ['admin_photo']


admin.site.register(CamminoImage, CamminoImageAdmin)

so is for friends and books

from django.contrib import admin

# Register your models here.
from .models import Friend

admin.site.register(Friend)

from django.contrib import admin

# Register your models here.
from .models import *


admin.site.register (Author)
admin.site.register (Press)

@admin.register (Book)
class BookAdmin(admin.ModelAdmin):
    filter_horizontal = ('authors',)

In views there is nothing related to admin/login

from django.shortcuts import render
from django.http import HttpResponse


def home(request):
    return render(request, 'camminiverticali/home.html')


def about(request):
    return render(request, 'camminiverticali/presentazione.html')


def search(request):
    return render(request, 'camminiverticali/search.html')


def robots(request):
    return HttpResponse('robots')

Also the views from within the three apps don’t mention login

[KenWhitesell]

May need to dig a little deeper here.

The first line of the traceback you posted was:

What was the traceback above this line?

The last portion of the original traceback:

@85oppilif

  File "/home/oppilifitrof/.virtualenvs/camminiverticali_2_0/lib/python3.7/site-packages/django/db/backends/postgresql/utils.py", line 6, in utc_tzinfo_factory
    raise AssertionError("database connection isn't set to UTC")
AssertionError: database connection isn't set to UTC

That is really interesting.

Other than the password (which you should remove or obfuscate), what is your DATABASES setting?

[85oppilif]

DATABASES = {
    'default': {
        'ENGINE': 'django.contrib.gis.db.backends.postgis',
        'NAME': 'oppilifitrof_camminiverticali',
        'USER': '*******',
        'PASSWORD': '*******',
        'HOST':'localhost',
        'PORT':'5432',
     }
}

Thank you for pointing out the problem of Database time. I found some discussion on stackoverflow underlining an incompatibility between my versions of psycopg2 and django 3.0. The problem can be either solved by upgrading django or downgrading psycopg2. I tried with the latter and now the admin page is working.
Thanks very much for your patience
