My domain name keep switching from example.com to mydomainname.com
After struggling to finish the project, I built a sitemap. After pushing it digital ocean, I and signing up to Google search console it gave out an error (from Google console) invalid domain name. When I looked at the generated file from mydomainname.com/sitemap.xml I saw that example.com is appended to sitemap instead of my domain name. I removed example.com from Sites. But it's showing same thing. I found an article on stackoverflow and realised that I should've changed the name from instead of deleting it. I went on my server and turned the id of mydomainname.com to 1 from the database, now mydomainname.com and example.com is swapping ..? How can I fix this? -

Django/Django REST Framework - Internal API displaying results fetched from external API with filtering
So hey guys currently I'm trying to create an API endpoint that calls an external API via url with some filtering by comma separated strings. I'm used to creating internal APIs with models and views that call from it's own local sqlite database. But I'm less familiar with this. For instance I'm trying to have it so when I open my django devserver for this endpoint say called 'api/data/' it gets the JSON response from say 'www.example.com/api/data?tags=beef,chicken' and displays it. I was thinking about something like the code but wasn't sure how to apply filtering to it without accessing the queryset. import requests from rest_framework import status from rest_framework.response import Response def external_api_view(request): if request.method == "GET": r = requests.get("https://example.com/api/data/") -

How I can store hashed access tokens in the database?
I use django-oauth-toolkit in my application. I noticed that the tokens are stored in the database in raw(unhashed) form. I think it is not secure. I was looking in the documentation and did not find a way to store hashes instead of tokens in db. Did I miss something, or does it really work like that? How can I fix this for my application? -

Can't create user with custom user model and hash password DJANGO
I created a custom user model for my users in django and I'm using django rest framework and Jwt along with angular as my frontend. It was working fine while I was using superuser to login, but now that I've created new users I can't login with them, only with superuser. The main problema that I noticed is that the password wasn't being hashed, so the question is, How can I hash the password when I create an user posting the User from Angular?? is it right the way I'm doing it?

Download Button Redirecting to Wrong Page
In my Django project, a user submits an Elasticsearch query into a form and it returns a downloadable report generated from that query. We've made some changes, and now I'm trying to get the portion that returns the report working again. However, I'm running into an issue with my url pattern that should call on the view function to download the report. I have a Download Report button that appears once the report is done being generated (checked by an Ajax request). The idea is that a user will click the button, and the report will appear in their downloads folder. But, when I click the button it sends me to /report/return_doc/ instead of /return_doc/. The logic of sending the user to /return_doc/ is that it's associated with the return_doc function in my views, but can I trigger this function and download the report to the user without refreshing the page/sending them to a new url? Or do I need to do something entirely different to make this button functional? error message Page not found (404) Request Method: GET Request URL: http://0.0.0.0:0001/report/return_doc/ Using the URLconf defined in icm_audit_tool_app.urls, Django tried these URL patterns, in this order: admin/ accounts/ form/ report/ … -

Stop signal send trigger for specific Sender
I'm using Django 2.2 In my application, there is a shared user feature and every shared user are added to User model with is_shared field set to True.
