Sending email feature not working when run using Docker. Showing Error : 530, b'5.7.0 Authentication Required. But runs perfectly without docker
I am making a Django App using GraphQl APIs in which I am trying to make an email sending feature for changing and sending user password if they forget while login. This feature is perfectly working when I am running it from my laptop's localhost:8000, but when I pushed it to dockerhub using github actions, and pulled it and tried to run, it didn't work. The error is: "(530, b'5.7.0 Authentication Required. Learn more at\n5.7.0 https://support.google.com/mail/?p=WantAuthError w13-20020aa7954d000000b00574c54423d3sm14276612pfq.145 - gsmtp', 'webmaster@localhost')" Now it is saying "webmaster@localhost", this cannot happen as I am using smpt.gmail.com, also I have made the feature for creating environment variables in .github/workflows/main.yml file. This means somehow my docker-image is not able to access the .envvariables. All my secret credentials are correct as they work when I use it from my laptop's localhost server, but not in docker localhost server. Can anybody shed some light on this?

SESSION_COOKIE_AGE vs set_expiry() in Django
I have noticed different behavior between SESSION_COOKIE_AGE and set_expiry method. Usually, I am using set_expiry on login as it changes according to the user whether he/she selects REMEMBER BE or not. I understand that if I set SESSION_SAVE_EVERY_REQUEST to True, this means that the expiration date will be updated every time on user activity. However, I noticed that the expiration date of the session is updated on user activity without setting SESSION_SAVE_EVERY_REQUEST (default: False) and without modifying the session. On the other side, it is not working that way if I set SESSION_COOKIE_AGE only without custom setting of set_expiry. From the documentation, it is mentioned that if we set value using set_expiry: the session will expire after that many seconds of inactivity Is that means INACTIVITY in accessing the application or inactivity in modifying the session? And set_expiry equals SESSION_COOKIE_AGE plus SESSION_SAVE_EVERY_REQUEST=True? -
I am not able to perform update operation in crud

Where does business logic go in Django API
I am very new to Django. I am able to set up a basic endpoint thanks to all the tutorials but what many of them miss is Where does one put the business logic of the app?

How to embed an XLSX local file into HTML page with Python and Django
For a Python web project (with Django) I developed a tool that generates an XLSX file. For questions of ergonomics and ease for users I would like to integrate this excel on my HTML page. So I first thought of converting the XLSX to an HTML array, with the xlsx2html python library. It works but since I can’t determine the desired size for my cells or trim the content during conversion, I end up with huge cells and tiny text.. I found an interesting way with the html tag associated with OneDrive to embed an excel window into a web page, but my file being in my code and not on Excel Online I cannot import it like that. Yet the display is perfect and I don’t need the user to interact with this table. I have searched a lot for other methods but apart from developing a function to browse my file and generate the script of the html table line by line, I have the feeling that I cannot simply use a method to convert or display it on my web page. I am not accustomed to this need and wonder if there would not be a cleaner … -

How to use foreign key as a distinct value and sort the queryset with a timestamp field first in Django?
I am using Postgres in my django project and I want to get all the tickets based on a customer full_name search with distict customer_id and sort the ticket queryset based on card_timestamp field in Ticket model. I have two models like the following: class Ticket(BaseTimeClass, BaseDeletedClass): customer=models.ForeignKey(Customer,on_delete=models.CASCADE, related_name="generated_tickets") is_replied = models.BooleanField(default=False) is_resolved = models.BooleanField(default=False) card_timestamp = models.DateTimeField(blank=True, null=True) class Customer(BaseDeletedClass): created_at = models.DateTimeField(auto_now_add=True, blank=True, null=True, db_index=True) modified_at = models.DateTimeField(auto_now=True, blank=True, null=True) first_name = models.CharField(max_length=64, default="") last_name = models.CharField(max_length=64, default="") full_name = models.CharField(max_length=256, default="") I have tried with this: Ticket.objects.filter(Q(customer__full_name__icontains="shuvo")) .select_related("customer") .order_by("customer_id", "-card_timestamp") .distinct("customer_id") ) the problem with this query is, it is returning the queryset sorted by the customer_id 1st then using the card_timestamp. for better scenario, e.g. there can be multiple customer named with "shuvo": customer_id can be 1870, 1120, 3210, and their card_timestamp value is "13 january 2023", "28 december 2022" and "14 december 2022". expected scenario, the queryset should return customer_id 1870, 1120 and 3210 sequentially but it is returning customer_id 3210,1870, 1120. how to solve this problem using django-orm? thanks in advance! -

Save Django Website State across all browsers the app is accessed at
I have created a Django webiste which fetches data on a realtime basis through view and renders to the Html Template, I am already running serveral ajax queries to refresh my specific views to render and display data every second, but now i have a bigger problem which is to maintain the same state of the template accross all the browsers the Django server is accessed at. For example If user 'A' logs in and do certain operations on the webiste which changes the states of tables in my pstgres, and after an hour user 'B' logs in with same credentials he should be able to see the same operations running but right only the raw template is visible to user 'B'. I have created the middleware using postgres. I am not getting the solution to this since a long time now. I tries using ajax to call every view once but i don't think this solution is a long term because as more views get added more and more ajax calls will slow down the system. -

React, Django and FastAPI architecture
My team is developing a platform where our clients upload data through an API (typically once per hour). The data is analyzed and then made accessible through a web/dashboard of sorts. I don't have experience with Django/React so I'm struggling to understand how a good architecture should look like combining the following tools/frameworks: React for frontend Django as our web-server FastAPI as the API to upload data (and as DB access layer) (Note: FastAPI will run separatly - Django and FastAPI communicate through HTTP/JSON) My struggle is this: Do I need django? Can I just use React and the expose all data through FastAPI? Should I throw out FastAPI because I'm using Django anyway? (for API's FastAPI is so much better imo) The original idea was to have no public APIs and only allow our clients to upload data through our data upload API from specified IP addresses with authentication. Only our web-server should access our internal API's to serve data back to our dashboards. Is that an overdesign? Im running with the assumption that Django REST and authentication support is superior to using just React/FastAPI to service web-pages. The FastAPI is alread implemented based on current needs and the … -
