Add a custom admin action in Django when an object in another model is created
I wanted to implement one functionality in my Django application such that a custom admin action is created whenever an object is created in some other model. For e.g. I have one model as Semester: class Semester(models.Model): name = models.CharField(_("Semester Name"), max_length=30, default=None, null=True, blank=True, help_text="Name of the semester") def __str__(self): return self.name and another model as UnregisteredStudent: class UnregisteredStudent(models.Model): email = models.CharField(_("email"), max_length=30, default="") semester= models.ForeignKey(Semester, on_delete=models.SET_NULL, null=True, blank=True) def __str__(self): return str(self.email) In the UnregisteredStudent table I have emails filled up and am using custom admin actions to add semester field to each object in UnregisteredStudent table. My custom admin action in UnregisteredStudent looks like: @admin.action(description="Add Semester as Semester 1") def semester1(self, request, queryset): semester = Semester.objects.get(name="Semester 1") for obj in queryset: obj.semester= semester obj.save(update_fields=["semester"]) Now as I have done this for semester 1, as and when new semester objects are created I would need new such admin actions like: @admin.action(description="Add Semester as Semester 2") def semester2(self, request, queryset): semester = Semester.objects.get(name="Semester 2") for obj in queryset: obj.semester= semester obj.save(update_fields=["semester"]) Right now I have to add custom admin actions manually in my admin.py, but I suppose this might not be the correct approach to the problem as in … -

Indexing a SearchVector vs Having a SearchVectorField in Django. When should I use which?
Clearly I have some misunderstandings about the topic. I would appreciate if you correct my mistakes. So as explained in PostgreSQL documentation, We need to do Full-Text Searching instead of using simple textual search operators. Suppose I have a blog application in Django. Entry.objects.filter(body_text__search="Cheese") The bottom line is we have "document"s which are our individual records in blog_post field and a term "Cheese". Individual documents are gonna be translated to something called "tsvector"(a vector of simplified words) and also a "tsquery" is created out of our term. If I have no SearchVectorField field and no SearchVector index: for every single record in body_text field, a tsvector is created and it's checked against our tsquery, in failure, we continue to the next record. If I have SearchVectorField field but not SearchVector index: that tsvector vector is stored in SearchVectorField field. So the searching process is faster because we only check for match not creating tsvector anymore, but still we're checking every single record one by one. If I have both SearchVectorField field and SearchVector index: a GIN index is created in database, it's somehow like a dictionary: "cat": [3, 7, 18], .... It stores the occurrences of the "lexems"(words) so that … -

Django sockets don't work in production, when deployed in Azure Web App
Python version 3.10 Recently my websockets stopped working when deployed in Azure. I am using Python Django with Daphne. When run locally everything works fine also if ssh into the web server and run another instance of Django, I can locally also connect to the websocket. But when I'm trying to connect to websockets in production as a client, the socket connection instantly fails. Also when viewing logs it seems like they get redirected to HTTP requests? That is why I get a 404 error Not Found: /ws/notifications/ 169.254.129.1 - - [01/Jul/2023:10:14:35 +0000] "GET /ws/notifications/?token={myToken}HTTP/1.1" 404 2753 "-" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/114.0.0.0 Safari/537.36" The code gets built and deployed without any errors, so I am confused to why this is happening. My front-end is also calling the correct uri wss://api.pickme.lv/ws/notifications/. Also as I mentioned they were working previously, now they just stopped. Please ask if you required additional information, because tbh I have no clue where to start with this. I also have websockets enabled in my Azure config ], "vnetPrivatePortsCount": 0, "vnetRouteAllEnabled": true, "webSocketsEnabled": true, "websiteTimeZone": null, "windowsFxVersion": null, "xManagedServiceIdentityId": null } -

Python Knowledge and Its Relevance in Django Development
I spent a lot of time learning Python and building a strong knowledge base in it. My goal was to enter the Django domain and explore frameworks like DRF (Django REST Framework) to become a proficient Python developer. I started learning Django and DRF a couple of months ago, and it has been a good experience so far. My question is: up until now, I haven't had the opportunity to use the majority of Python's advanced tools that I learned. Is it because I am still a beginner in Django, or is it unnecessary to use these advanced tools such as enumerations, metaclasses, modules like fractions, descriptors, etc.? From what I've observed, it seems that a basic understanding of Python is sufficient to work with Django. Thank you for taking the time to answer my question. I expected that having a good knowledge of Python would give me a significant advantage. -
