Django ElasticSearch dsl drf returning duplicate search result
I have search based api views, when I search something, it return value, but return the duplicate value with that term. in my database, there is no duplicate data, even in elasticsearch build.

How to create a map of the floors that the user could reserve?
I came up with a space management application for each floor and building. I would like it to be a web application. After logging in, the user could select the building, floor and the floor map should be displayed. By pressing on a room, he could reserve it. How could I implement this "map with desks to reserve" in Django or in Angular or maybe in something else it would be easier? I found only solutions with using google maps, that is not what I am looking for. -
Concerns regarding DDoS-like abuse of Django user registration POST requests
I am working on an online shopping mall-esque app with some of my friends. I am in charge of the server-side but I am not really a well-versed backend engineer. Hence, I pivoted toward using DRF for simplicity's sake. However, what caught my eye was that someone could possibly run a script that just repeats POST requests with a valid format. So far, I haven't managed to think of a way to impose custom permissions on this action because people who do not yet have an account have no way of authenticating themselves. Any help on this matter (or built-in functionality that renders this concern moot) would be much appreciated. Thank you! -

Embed PDF file from download(ed) document
I used to ember pdf files with this simple code: <iframe src="file.pdf" style="width: 100%;height: 100%;border: none;"></iframe> which works perfectly for me. The file should be of course on the server, but is there any similar when I don't have direct "static" access to the file, only a link which serves the file as attachment like this: #django download = file(document.path, 'r') response = HttpResponse(download.read()) response['Content-Disposition'] = 'attachment; filename=' + \ document.get_clean_name() . Is it somehow doable if the file is served as attachment, and has a similar access link: http://sth.com/download_document/2022/ ? -

Place management application - What technologies? [closed]
I came up with a building space management application for each floor. I would like it to be a web application. After logging in, the user could select the building, floor and the floor map should be displayed. By pressing on a room, he could reserve it. In what technologies could I implement it? I was thinking about python and django, maybe some react, java and angular. I have no experience in building such an application. I only did a few projects in python, c ++ and java. I would like to find an example of such an application, maybe a video. I can't find anything like that myself. Any ideas? -

Running a streaming api python script on cPanel
I have looked over lots of info on running scripts in cPanel and I have successfully learned to do it with cron jobs etc. But with regard to a script that streams data via API I can’t find much info. Cron jobs sends me an email after execution so I know its working or not. However with a continuous data streaming script I do not know how to tell if it is running and working. I have figured I would need to setup a django web app interface to monitor it but I am not a web app programmer. Is there something out there that makes this easier? Or do I need to integrate the script into a django webapp (which means paying someone to do it for me…) ? -
How to overwrite all objects in Django database after uploading an excel file?
So I have a Leaderboard page and a Django model such as: models.py class Leaderboard(models.Model): rank = models.IntegerField() team_name = models.CharField(max_length=100) score = models.IntegerField() The thing I'm confused is how can I write the views.py function so that whenever I make a request and upload a new excel file to the views.py it would overwrite the old objects inside of the database and fill the database with the new data. I'm not sure if this is the correct way of creating a manual leaderboard but it's the only way I could think of currently. What I could think of so far: views.py def update_leaderboard(request): new_excel = request.body data = pd.read_excel(new_excel) # Overwrite the database here ... ADDITIONAL INFORMATION I'm using Django Rest Framework as well in this case, because I'm using React for my frontend. So the views might come out a little different (?) -

Send user to the page they requested before Signing in with google, after they sign in with google
I have a movie quiz app https://www.quizsocial.xyz/, where users can search for a trending movie and take a quiz about the movie’s story, so when they land on the homepage, they search for their movie, they click start quiz, they agree to the rules, they select how many questions they want to attempt and then they have to sign in with google or create an account, now if they create an account through us, their requested quiz will start automatically once they sign in, but when they do the same thing with google log in, they are redirected to the homepage. Where they have to search for the quiz again, agree to the rules, select how many questions they want to attempt. This may annoy some users and lead them to leave the website and never come back. My question is how do I retrieve their data before they signed up with google and then send them to the exact page they requested after they sign in with google.
