Django migration already applied but I don't have the migration file
A migration was applied to the database, and the table "blacklist_id" exists (and is populated with rows.) I want to add a new Model and make a migration, but whenever I call makemigrations Django thinks that the blacklist_id model is new and attempts to make a migration for that, which causes an error.

Change Meta with Rest API Javascript
I have a web app, where Django with Django-rest-framework is set as the backend and html+css+javascript on the frontend. And they communicate using RestAPI. So... My Django is available on the pages: 'domain.com/api' and 'domain.com/admin'. On the page 'domain.com' my frontend part is available. And my question is... Are there any ways to change Meta on the frontend using Django? And I also need analytics to see these Meta and in-browser searches show the description and title, that I got from my backend model. -
Dynamically pass arguments to objects.filter
I am pretty new to Django and I am trying to get a query set from a filter function. This filter function is supposed to be able to take 1 to 5 arguments and I am not sure how to handle that. I have not found anything here that might help me, so if you do know of some other question that might help please let me know. views.py: @api_view(('Get',)) def update(request, REQUEST): if request.method == "Get": requestlist = REQUEST.split('&') for keys in requestlist: if 'module' in keys: module = keys[8:] if 'value' in keys: value = keys[6:] if 'user' in keys: user= keys[5:] if 'time1' in keys: time1 = keys[6:] if 'time2' in keys: time2 = keys[6:] item = Post.objects.filter(name=Name, user=USER, ...) The full request string will look like name=NAME&value=VALUE&user=USER&time1=FIRSTTIME&time2=SECONDTIME but it could also be any combination of the individual variables like name&time1. Now I want to be able to do that with one filter method instead of creating like 2^5 for each different szenario. -

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) File "/path/to/env/lib/python3.6/os.py", line 220, in makedirs mkdir(name, mode) During handling of the above exception ([Errno 13] Permission denied: '/thisisnewappfromServer'), another exception occurred: File "path/to/env/lib/python3.6/site-packages/django/core/handlers/exception.py", line 47, in inner response = get_response(request) File "/path/to/env/lib/python3.6/site-packages/django/core/handlers/base.py", line 179, in _get_response response = wrapped_callback(request, *callback_args, **callback_kwargs) File "/home/rohit/Documents/Web_app/project/new_models/views.py", line 70, in formFields call_command('startapp', new_name) File "/path/to/env/lib/python3.6/site-packages/django/core/management/__init__.py", line 168, in call_command return command.execute(*args, **defaults) File "/path/to/env/lib/python3.6/site-packages/django/core/management/base.py", line 371, in execute output = self.handle(*args, **options) File "/path/to/env/lib/python3.6/site-packages/django/core/management/commands/startapp.py", line 14, in handle super().handle('app', app_name, target, **options) File "/path/to/env/lib/python3.6/site-packages/django/core/management/templates.py", line 74, in handle raise CommandError(e) Exception Type: CommandError at /models/details/ Exception Value: [Errno 13] Permission denied: '/thisisnewappfromServer' Please help me out here.
