Dockerizing django, postgres, gunicorn, ngnix - only admin static works, other 404

I have managed to put it on server, run it on docker with SSL, but main problem is that only admin static files load, other give 404 error. Weird thing is that static subdirectories structure is kept, but there are no files inside.

How to optimize a DjangoORM reverse foreign key query?
I have the following relationships: I'm trying to select all tasks with all instances and their vehicle. This however is a very slow query. To my understand I have to use prefetch_related because it's a OneToMany relationship. My InstanceModel has a reverse foreign key to Task: task = models.ForeignKey(TaskModel, on_delete=models.CASCADE, related_name="instances") I've attempted a query like this in DjangoORM: TaskModel.objects.filter(department_id=department_id).prefetch_related("instances", "instances__vehicle") But it's very slow. Is there any way to optimize this or due the relationship inherently restrict this query pattern? Running in Django 3.x -
How to convert ' to quotes in javascript?
I am trying to pass a python list with string values from views.py to the template where a javascript uses the same for labels of a pie chart(plotly). The issue is when the list is received at the front-end, the list is getting the hexcode of the quote which is ' instead of the quotes. How to convert it to quote? Here is the snippet: var trace1 = { x: {{labels}}, y: {{values}}, marker:{ color: ['rgba(204,204,204,1)', 'rgba(222,45,38,0.8)', 'rgba(204,204,204,1)', ] }, type: 'bar' }; Now, i am getting the values for 'labels' as: [&#x27;One&#x27;, &#x27;Two&#x27;, &#x27;Three&#x27;] Instead of: ['One','Two','Three'] Just wanted to know are there any methods to avoid this easily instead of using string replace methods? -
Get first element from many to many relationship django in template
I'm trying to get the first element from queryset which is returned by a Model Field which is a ManyToManyField right in the template. models.py class CraftImage(models.Model): image = models.ImageField(upload_to='crafts_images/', null=True) class Craft(models.Model): title = models.CharField(max_length=100, null=False, blank=False) images = models.ManyToManyField(CraftImage, blank=True, related_name='craft_images') views.py def work_all(request): crafts = Craft.objects.all() context = { 'crafts': crafts, } template.py {% for craft in crafts %} <div style="background-image: url('{% static 'craft.images[0].image.url' %}');"></div> {% endfor %} Something like this. I've also tried following some solutions I found which didn't work for me such as.. views.py crafts = Craft.objects.all() images = Craft.objects.values_list('images').first() print(images) context = { 'crafts': crafts, 'images': images } templates.py {% for craft in crafts %} <div style="background-image: url('{% static 'images.image.url' %}');"></div> {% endfor %} -
