What model/approach to use to relate space and objects in django

Set CharField to RTL in Django Admin site

Python - order python list by datetime object
I have a list of datetime objects that's being appended into an array from my database with an additional library called Django Recurrence. I append it as follows inside a for loop: events = Events.objects.filter(...some conditions) timeslots = [] for event in events: for occurence in event.recurrences.between(context['today'], context['end']): occurence_date = datetime.combine(occurence.date(), time(0, 0)) timeslots.append({ 'start_date': occurence_date + timedelta(hours=event.start_time.hour, minutes=event.start_time.minute), 'end_date': occurence_date + timedelta(hours=event.end_time.hour, minutes=event.end_time.minute), }) It would then output it as [{'start_date': datetime.datetime(2022, 3, 7, 14, 0), 'end_date': datetime.datetime(2022, 3, 7, 15, 0)}, {'start_date': datetime.datetime(2022, 3, 8, 14, 0), ... }] which is great. A side effect from the events loop, is that it would add a the other events, after all the occurrences, eg 1 march, 5 march, 10 march, 2 march, 4 march, etc etc etc. I'd like to order them by the starting date, so I can render them out in the correct order in my template.

Using for django loop inside of a JavaScript variable
I want to loop through a django query in JavaScript, example: musics = Music.query.all(). I did something like this: const songs = [ {% for music in musics %} { id: "{{music.id }}", songName: "{{ music.title }}", poster: "{{ music.cover_image.url }}", } {% endfor %} ] Array.from(document.getElementsByClassName("songItem")).forEach((element, I) =>{ element.getElementsByTagName('img').src = songs[I].poster; }) I get Uncaught TypeError: Cannot read properties of undefined (reading 'poster'), but if I use console log console.log(element.getElementsByTagName('img').src = songs[I].poster); ``` it works in the console.
