Implementing a following system and fetching posts of people a user follows in django

Django API: Revoke tokens after a certain amount of request
I am trying to code an API that would receive a string or a list of strings and return my model's predictions. I use token authentication for the ease of use, however, I don't understand/can't imagine how I can limit the amount of requests a user can make on a per month basis. Or give a limited amount of requests to an anonymous user.

How to convert an object in django rest framework to a hyperlink

Unexpected format when passing a DateField straight to a template
I have a DateField on my model. And I'm passing the fields value straight into a DocxTemplate, where it comes out as "YYYY-mm-dd" format. I was wondering if there is a way of letting Django format the date so that it comes out in a localised format? In "models.py": class Bar(models.Model): date_fld = models.DateField() Generating the "docx": from app.models import Bar from django.shortcuts import get_object_or_404 from docxtpl import DocxTemplate ... bar = get_object_or_404(Bar, pk=1) tpl = DocxTemplate("tpl.docx") context = { 'foo': bar.date_fld, } tpl.render(context) tpl.save("result.docx") I know that I could use a function to convert the date to a string, but it doesn't seem like a Django way of doing things: def getDateString(date): return date.strftime('%d/%m/%Y') And then: context = { 'foo': getDateString(bar.date_fld), } -

How to communicate from a webserver to a local device using UDP?
Here's the scenario: I have a webserver(django) hosted on the cloud, which needs to send some data to an android application (also developed by me) when some event occurs. I don't want to use polling using Http or other protocols from the android. What i want is the webserver to send the data via UDP (socket programming on both android and django). I have tested this by hosting the webserver on my local computer and providing the local IP of the android devices. It works perfectly. The scenario changes when the same server is hosted on the cloud as now, I don't know the public IP of the Android devices. WhatismyIp on google simply shows the public IP of the router which is not enough to route the packets to my local devices. Using a VPN and its managed IP works ofcourse, but is there a way to do this without a VPN? Any help will be appreciated. -
How to work with multiple server and databases in Django?
So I few data collection tasks that involves saving data on multiple servers.

Now I am accessing the second server using multiple database functionality in Django but it is kind of slow to fetch data from second server and then do operations on it. Is there any solution for faster operation Or a master server kind on thing? -

CKEditor deleting <span> in Django
I'm having a problem with CKeditor (with ckeditor_uploader) in Django, I looked everywhere, found a lot of answers but none of those worked.

Facebook Link Sharing Issue
I have a single "share to facebook" link on my site using Django Social Share. The issue is that the link being posted to Facebook isn't being scraped - the image, the description, and the title are not populating. All OG meta tags are present and correct, so I checked the Facebook Sharing Debugger and it shows the following error: SSL Error Can't validate SSL Certificate. Either it is self-signed (which will cause browser warnings) or it is invalid. Curl Error Curl error: 60 (SSL_CACERT) The site's SSL cert is perfectly valid - no errors or warnings at all. I'm using LetsEncrypt on Apache with a Django app behind it through WSGI. No issues with any other social networks. An example of one of the links giving this error: https://www.netizen.net/news/post/2643/netizen-ranks-184-on-the-2020-inc-5000-list As you can see if you visit the page, there are no SSL errors. The same link is scraped just as expected on LinkedIn, Twitter, and elsewhere but FB seems to have this issue. -

Django FormModel Validation
Background: Using the Django Admin framework, I'd like to run validation to make sure a record doesn't exist with the same values before saving. Using a form, I added a check in the "clean" method. That validation works exactly as I expect. I am successfully able to add NEW records and catch duplicates. THE PROBLEM: The form is also validating the TabularInlines. Since the "parent page" isn't changed/updated it's not being sent and it's not showing up in the "cleaned_data." Thus, when it's not checking to see if the parent record exists, it throws a KeyError. IE, "hey, you said to check these parent variables and they aren't in here, wth?" Question: Using forms, is there an elegant way to check the ModelAdmin (parent page) and the TabularInLines (child page) separately to avoid the key error? OR do I just hard code checks for the different chunks if they exist? Different forms for different inlines? I'm providing some PSEUDO CODE below that should help outline the issue. DISCLAIMER: The actual structure is more complicated. Yes, I realize in this EXAMPLE, there is a better way to handle this. However, I'm looking to solve the form validation issue. ########## # Models … -

Sorting by Value of Object in Many to Many Field Django
I need some sorting help with django querysets that involve many to many relationships. I'm making a language-based conversation app and I've just finished writing a query that returns a queryset named possibleMatches containing the users someone might want to chat with. However, now I want to sort those users by the level of a specific language they have in their user languages table. I believe the solution lies in using Django's annotate() function for sorting querysets, but I've been having trouble finding the exact syntax to do it. I've also tried using filtered relations, but when running it, I got an error saying that filtered relations don't support nested conditions. Each user has an id and a list of user languages represented by a many to many field. Each user language corresponds to one user, one language, and one level.
