Is there a feature in Django for saving a history of files uploaded by a user?
I have built a Django application that allows a user to upload his/her resume. The resume can be of any format(.pdf, .txt and even .mp4 video). The user also has the option to update the current resume by uploading a new file. I wish to have a feature wherein the user has the option to go back to his/her history of uploaded resumes to view the old ones. Django's FileField model object only keeps track of the latest upload. Is there are any existing feature in Django that would help me in easily build a feature wherein a history of uploaded files are maintained? -

Database schema to map Hotel Amenities from different sources into a uniform format to remove duplicates
I am creating a hotel application that fetches hotel feeds from different sources and store it to database to form a uniform structure and expose API to the mobile application. I am fetching hotels from 3 different sources using python/django app. Now every hotel source has different sets of amenities for example: Source 1 [Expedia] - Free WiFi - Hairdryer In Room - Cable TV - Double Bed - Single Bed - Fireplace Source 2 [SomeHotelProvider] - WiFi - Hairdryer - Television - and so on So here we have same amenity name with different name (Free WiFi and WiFi ) for example. The only problem is that at the Mobile screen it will display two filter [Free WiFi, Wifi] to filter out the result set. So what is best approach to deal with these duplicate values. Need a solution to create a mapping table that maps all duplicates to one amenities master table. Thanks in advance. -

Django Rest Response when data is already in JSON
class Ebay(APIView): #permission_classes = (permissions.IsAuthenticated,) #renderer_classes = (JSONRenderer,) def get(self): search = EbayFind(keywords='phone') result = search.get_results() return Response(result.json()) #return HttpResponse(result.json()) this returns it correctly I have created a simple non-model API endpoint using DRF to return some JSON using results.json() on a requests object. It is again converted into JSON in the Response (giving double backslashes and ruining the JSON), whereas HttpResponse returns it fine. I haven't set any default renderer in settings.py so how could I stop it converting the response to JSON for this endpoint? -

Can't import custom Middleware whilst using @decorator_from_middleware. (Non Global Middleware)
I was using some custom middleware to check auth of users. This was working great but I don't want to run this middleware on every url. Suggestions point towards using @decorator_from_middleware before each view that you want middleware to run, this would be ideal. Some of my view should be global, others behind auth. I cant seem to import the middleware to call it in the views file. My views.py: from myapp.middleware import * @decorator_from_middleware(AuthCheckMiddleware) def index(request): return render(request, "index.html") My myapp.middleware.authCheck.py: class AuthCheckMiddleware(object): def __init__(self, get_response): self.get_response = get_response def __call__(self, request): #CHECK AUTH HERE response = self.get_response(request) return response def process_exception(self, request, exception): return None The error I get: File "/vagrant/myapp/django-project/isadmin/web/views.py", line 93, in <module> @decorator_from_middleware(AuthCheckMiddleware) NameError: name 'AuthCheckMiddleware' is not defined -

Keycloak Custom Automatic User Attributes
Im using Keycloak in a somewhat unconventional way (I think). I want a user to be able to register on the Keycloak register page and have that user synced to a LDAP server for authentication against a git server running CentOS. When i register a user, this user is indeed synced to the LDAP server. However, it lacks several attributes to be able to authenticate against the git server, namely: UID, GID, Objectclass: posixAccount, loginShell: /bin/bash, homeDirectory: /home/user I have tried creating default groups and roles with attributes, but this doesnt work, the synced user on the LDAP server does not inherit any of these attributes. I think it has to be hardcoded in somewhere or could it be added with mappers? -
