how do I arrange toast messages with javascript
I'm working on a toast message setup where when if multiple of them are active they're not visible except the one in the front (so maybe a margin of 15px between them would help) and display them on the bottom-corner of the screen(fixed) doesn't change position when scrolling and make them disappear after 3 secs one by one. How do I go about solving this with javascript? Maybe it's possible to target "color" as in "color-green". Thx for any help! {% if messages %} {% for message in messages %} {% if message.tags == 'success' %} <div class="color-green"> <div class="color-white"> <div class="icon-success"> <i class="fas fa-check icon"></i> </div> <div class="text"> <h2>{{message}}</h2> </div> </div> </div> {% elif message.tags == 'info' %} <div class="color-blue"> <div class="color-white"> <div class="icon-info"> <i class="fas fa-info icon"></i> </div> <div class="text"> <h2>{{message}}</h2> </div> </div> </div> {% elif message.tags == 'warning' %} <div class="color-orange"> <div class="color-white"> <div class="icon-warning"> <i class="fas fa-exclamation-circle icon"></i> </div> <div class="text"> <h2>{{message}}</h2> </div> </div> </div> {% elif message.tags == 'error' %} <div class="color-red"> <div class="color-white"> <div class="icon-cross"> <i class="fas fa-times icon"></i> </div> <div class="text"> <h2>{{message}}</h2> </div> </div> </div> {% endif %} {% endfor %} {% endif %} .color-green{ bottom: 0; position: absolute; background-color: #40ff00; box-shadow: 4px … -

I am currently coding my first django website, and I am experiencing some troubles with the urls.

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 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). -
