Handling notification Redirects to mobile apps and the frontend with Django Rest Framework
My project is in Django rest framework. It have web with react as well as android and ios. I am using Firebase push notification for notification purpose. Since I have to show my notification in app also, I have stored the notification in database and the notification database is as below: class Notification(models.Model): """ model to manage all notification """ receiver = models.UUIDField(max_length=255) title = models.CharField(max_length=255) body = models.TextField(blank=True, null=True) type = models.CharField(max_length=255) # order_type, registration_type is_read = models.BooleanField(default=False) redirect_url = models.CharField(max_length=255) Now the main problem I am facing is setting a redirect url for every notification. I want to redirect to specific page for different type of notification. For example for order_type notification i want to redirect user to order page, for comment_type notification I want to redirect user to comment page. How can I do that since i cannot just simply redirect to html url since there is react app, ios app as well as android app. I did not find much resource regarding this. Any help will be very much appreciated. Thanks. -

django postgres different values
Hi Django + Postgresql While studying aware datetime, I had a question and asked a question. Postgresql document For timestamp with time zone, the internally stored value is always in UTC (Universal Coordinated Time, traditionally known as Greenwich Mean Time, GMT). An input value that has an explicit time zone specified is converted to UTC using the appropriate offset for that time zone. If no time zone is stated in the input string, then it is assumed to be in the time zone indicated by the system's TimeZone parameter, and is converted to UTC using the offset for the timezone zone. Are you changing only the output differently according to the timezone setting value? (internally stored value is UTC ?) SET TIME ZONE 'KST' (Asia/Seoul +9) Why is the same query but different values? Django Settings TIME_ZONE = "Asia/Bangkok" # ( +7 ) USE_TZ = False Postgres Settings SET TIME ZONE 'KST' (Asia/Seoul +9) Django Server TimeZone UTC Django ORM Create Query INSERT INTO "timezone_timezone" ("datetime") VALUES ('2022-11-22T01:58:14.373201'::timestamp) RETURNING "timezone_timezone"."id"; args=(datetime.datetime(2022, 11, 22, 1, 58, 14, 373201),) psql select query psql insert Django ORM Query INSERT INTO "timezone_timezone" ("datetime") VALUES ('2022-11-22T01:58:14.373201'::timestamp) RETURNING "timezone_timezone"."id"; psql select query -
Django - Get ID before ensuring form is valid
I am facing an issue where I have multiple forms on one page. What I am trying to do is update an item using an update form.

Django logging missing while testing through the interactive shell
We added the below to show the SQL queries on the console. And, as a proof of concept, we are following the online tutorial to build a testing project. LOGGING = { 'version': 1, 'disable_existing_loggers': False, 'handlers': { 'console': { 'level': 'DEBUG', 'class': 'logging.StreamHandler', }, }, 'loggers': { 'django.db.backends': { 'level': 'DEBUG', 'handlers': ['console'], } }, } At the step of "Explore the free admin functionality", for example, the console SQL logging works as exacted. So, when clicking on the button, we see sample SQL logs like attached below. However, when using the interactive shell through the command python manage.py shell, and calling python commands like Choice.objects.filter(question__pub_date__year=current_year), we did not see any SQL log. We wonder if we missed anything for the backend logging on the interactive shell. We are testing with Django v3.1.4 and Python v3.7.6. Just let us know if you need more details. Sample Django backend logging records: ...

How to implement a user customizable and personalized dashboard with django
I've created a django website with user accounts and a database containing data and I would like each user to be able to create their own personalized dashboard to view only the data that they care about. How can this be implemented where each dashboard is connected to the specific user that created it? My question is a little vague because I don't know how to implement a feature that is created by a user, is viewable only by that user, and is persistent. Any help or guidance would be much appreciated! I haven't tried anything yet because I don't know how to get started. Online search results are things like creating a custom admin dashboard or a dashboard that is shared across all users, which is not what I'm looking for. -

I am using django-microsoft-auth to log in with Microsoft account.

My URL that I added in Azure is default one: https://<mydomain_name>.com/microsoft/auth-callback/ I found this solution on Stackoverflow but it requires changing URL on Azure AD. Is there any other way to change reditect from /admin to /home other than changing URL in Azure AD? I was thinking if I could change it somehow directly in library. -
