Visualize data from elasticsearch in django app
I'm currently struggling on how to approach this. Currently I have a web application built with django and I have quite some data in elasticsearch. The web app should retrieve data from elastic, process this data and present this data graphically to the user (pie charts, tables, ...). Processing the data from elasticsearch will require some sorting/aggregating/deduplicating/adding up/... . I'm considering the following approaches for now: Get data from elastic via normal queries, process data further in web app using standard python and visualize it using some library (e.g., d3.js). Get data from elastic via normal queries in kibana, visualize data in kibana and integrate visualization in web app (not sure if this is going to work). Get data via elastic eland, convert to pandas data-frame, process data with pandas and visualize data using some library (e.g., d3.js). I'm strongly considering this approach currently. Is one of this approaches a good idea, what would be a better approach? Btw: I have quite some experience in Splunk and with Splunk queries this could be done easily - but Splunk is too expensive for this project :( Thank you! -
django get view method name on permission classes like actions
I have a custom permission like: def has_permission(self, request, view): print("view", view) I am calling list() method of ListModelMixin. Here when I print the value of veiw it gives me class name of the view. But what I want is the name of the method that is being called, in this case list. In view set we can get method name from action attribute. Is there anyway I can get name of the method not the class ?? -
How to apply if else, if the keyword entered in search bar does not exists in Django

If no post title matches that keyword a black page is returned. Instead of a blank page I want a paragraph saying that "no post matches the title " -
Django Debug View, in Production for Admins
I know that settings.DEBUG should be False in production. Nevertheless I would like to show the great django debug view in production, if the current user is authenticated as an admin. I read the Error Reporting Docs, but could not find a setting to turn this on. If it is easier to enable a different debug-view, this would be great, too. At least I want to see a nice stacktrace to understand quickly where the error comes from (without looking at logs). -

How to set up Gunicorn and NGNIX for a Django project in a production environment?
I'm trying to re-create a production environment on my local computer before deploying the Django project I have built on a server. I am using Gunicorn and NGNIX. When I launch Gunicorn by writing gunicorn mydjangoproject.wsgi, I get my Django project displayed on the address http://127.0.0.1:8000, but without any static files. That tells me that the error lies somewhere within NGINX, but I can't figure out where. I have followed this guide in order to set up Gunicorn and NGNIX on my local computer. I have skipped steps 5 to 7 in the guide because I do not want to deal with sockets on my local computer.
