CommandError in django while using call_command(startapp, app_name)

Question

I want to create a Django app from user input. Here is my code.

def createAppname(name):
    split_name = name.split(" ")
    
    s = "".join(i[0:] for i in split_name)
    return s

def formFields(request):
    if request.method == 'POST':
        app_name =  request.POST.get('app')

        new_name=createAppname(app_name)

        from django.core.management import call_command
        call_command('startapp', new_name)

        return render(request,'forms_new.html')

    return render(request, 'forms_new.html')

The code works perfectly when I am executing in the development environment. But after deploying on the production server, here I'm using apache_mod_wsgi, I get the following error.

Traceback (most recent call last):
  File "/path/to/env/lib/python3.6/site-packages/django/core/management/templates.py", line 70, in handle
    os.makedirs(top_dir)

    mkdir(name, mode)

During handling of the above exception ([Errno 13] Permission denied: '/thisisnewappfromServer'), another exception occurred:

Exception Type: CommandError at /models/details/

Please help me out here. Thanks.
