AttributeError after POST request in Django
I am making a post request to a Django server I am running locally. I am sending the request to http://127.0.0.1/login/. Here is the view @csrf_exempt def login(request): json_data = json.loads(request.body.decode('utf-8')) print(json_data) return request.body I have @csrf_exempt for now only just so that I won't have to make a view to get the csrf token. When I send the POST request it works and prints out the json I sent with the request yet it also prints out this error. Internal Server Error: /login/ Traceback (most recent call last): File "C:\Users\Moham\AppData\Local\Programs\Python\Python37\lib\site-packages\django\core\handlers\exception.py", line 47, in inner response = get_response(request) File "C:\Users\Moham\AppData\Local\Programs\Python\Python37\lib\site-packages\django\utils\deprecation.py", line 119, in __call__ response = self.process_response(request, response) File "C:\Users\Moham\AppData\Local\Programs\Python\Python37\lib\site-packages\django\middleware\clickjacking.py", line 26, in process_response if response.get('X-Frame-Options') is not None: AttributeError: 'bytes' object has no attribute 'get' The reason this is confusing me is because I have made no reference to any object called "bytes" or any attribute called "get". Anyone know what is going on here? -
Can't see custom field in Django Admin page
I'm trying to create my own User class called Customer which extends the AbstractUser model and has an additional field called address.

Django Channels: How to pass incoming messages to external script which is running outside of django?
I have started a private project with Django and Channels to build a web-based UI to control the music player daemon (mpd) on raspberry pi. I know that there are other projects like Volumio or moode audio etc. out of the box that is doing the same, but my intension is to learn something new! Up to now I have managed to setup a nginx server on the pi that communicates with my devices like mobile phone or pc. In the background nginx communicates with an uWSGI server for http requests to Django and a daphne server as asgi for ws connection to Django Channels. As well there is a redis server installed as backend because the Channels Layer needs this. So, on client request a simple html page as UI is served and a websocket connection is established so far. In parallel I have a separate script as a mpd handler which is wrapped in a while loop to keep it alive, and which does all the stuff with mpd using the python module python-mpd2. The mpd handler shall get its commands via websocket from the clients/consumers like play, stop etc. and reacts on that. At the same time, … -

Reorder django core functionality
I faced with the problem of Django multi site project. Each site can handle multiple languages. Project handle languages by url and we don’t use default language prefix. For example Site one: root / specify russian language and /en specify english version of site (default language is russian) Site two: root / specify english language and /ru specify russian version of site (default language is english) Django has a problem. Framework cache resolver and store prefixes for some sites. When I begin to use different default languages for different domains I was confuse with wrong prefixes. I must change behavior of django get_resolver() function becouse of hist @functools.lru_cache decorator (this is django file): def get_resolver(urlconf=None): if urlconf is None: urlconf = settings.ROOT_URLCONF return _get_cached_resolver(urlconf) @functools.lru_cache(maxsize=None) def _get_cached_resolver(urlconf=None): return URLResolver(RegexPattern(r'^/'), urlconf) Can I do something to disable cache? Or make cache depend of site? I tried to reorder function in django core module My solution is: from django.urls.resolvers import URLResolver, RegexPattern @functools.lru_cache(maxsize=None) def get_resolver_for_site(site_id, urlconf): return URLResolver(RegexPattern(r'^/'), urlconf) def _get_cached_resolver_for_site(urlconf=None): return get_resolver_for_site(get_site().id, urlconf) @receiver(post_save, sender=SiteSettings) def clear_url_resolver_cache(sender, **kwargs): get_resolver_for_site.cache_clear() resolvers._get_cached_resolver = _get_cached_resolver_for_site So I defined custom function, that return url resolver and cache it depend of site.

Django Template - If both IF statements are empty
I know how to use an if statement in django, and if the if is empty.

So how do I make sure it checks if both statements are false, and only if they are both false, to run the else. Any suggestions? -
