I need to upload templates through django admin panel which contain index file along with static files

Question

I am trying to make a portal where I take landing page template from different users and check manually that template is working file or not.

If everything looks good then I want to upload that theme from my django admin panel which create a new folder for every template like in this case its template1, template/theme/template1/index.html folder and also same with static files I want to upload zip file for all folders of static file and what will happen in backend is it go to folder static/template1/(unzipped static files) where unzipped static files is the location where all the static file will unzip itself so that my index.html and static files can communicate with each other.

I am not able to find any solution for this.

How can we make a model for uploading file like this to make a new folder every time?

from django.db import models

from django.contrib.auth.models import User
from django.db import models

class themes(models.Model):
     index_file = models.filefield(upload_to=???????)
     static_files = models.filefield(upload_to =?????)

Also I don't want to do collect static every time i upload a new template design.

Edit 2 here >> In my models.py I tried doing this but I am getting errors in it. , where I am doing wrong ?

def index_path_upload(instance, filename):
    if not instance.pk:
       # get count of all object, so is will be unique
       number = instance.__class__.objects.count() + 1
    else:
       number = instance.pk
    # replace filename to all object have the same
    filename = "index.html"
    return f"templates/theme/template{number}/{filename}"

def static_path_upload(instance, filename):
    if not instance.pk:
       # get count of all object, so is will be unique
       number = instance.__class__.objects.count() + 1
    else:
       number = instance.pk
    # replace filename to all object have the same
    return f"static/template{number}/+.zip"


class themes(models.Model):
     index_file = models.FileField(upload_to=index_path_upload)
     static_file = models.FileField(upload_to=static_path_upload)

do I need to add other things in my setings file , currently this is what I have.

STATIC_URL = '/static/'
STATICFILES_DIRS = (
    os.path.join(BASE_DIR, 'static'),
)
STATIC_ROOT = os.path.join(BASE_DIR, 'assets')


MEDIA_URL = 'static/'
MEDIA_ROOT = (os.path.join(BASE_DIR,'static/'))

Answer 1

why not like this ?

the upload_to key in FileField accept a function like this

def index_path_upload(instance, filename):
    if not instance.pk:
       # get count of all object, so is will be unique
       number = instance.__class__.objects.count() + 1
    else:
       number = instance.pk
    # replace filename to all object have the same
    filename = "index.html"
return f"template/theme/template{number}/{filename}"

the instance params is your object ( themes models ) ,the filename params is original filename of uploaded files

so your models like

def index_path_upload(instance, filename):
  ...

class themes(models.Model):
     index_file = models.filefield(upload_to=index_path_upload)
     ...

edit:

from django.conf import settings
import os


def index_path_upload(instance, filename):
    if not instance.pk:
       # get count of all object, so is will be unique
       number = instance.__class__.objects.count() + 1
    else:
       number = instance.pk
    # replace filename to all object have the same
    filename = "index.html"
    path =  f"templates/theme/template{number}/{filename}"
    return os.path.join(settings.BASE_DIR, path)

is will uploaded on your root directory ( where is manage.py ) + path be warning with that , is a big security flaw !
