Add property to instance method Django instance
I am now rewriting the legacy project. This ProductNode instance image will be rendered in the Django HTML template and serve by webserver. Since the author of the code has gone from company. I am now contributing the concept of previous project and reuse it as a model, but not entirely. I have read Adding attributes to instance methods in Python But could not see how does it related to my case class ProductNode(models.Model): ... def image_img(self): if self.image: return u'<img src="%s" width="75" height="75" />' % (self.image.url) else: return '(No image)' image_img.short_description = 'Image' image_img.allow_tags = True Questions: 1. image_img is an object method.

Method GET not allowed in DRF ViewSet when trying to retrieve single resource
I am new Python and Django. I have created ViewSet as follows: api/views.py class UserDetails(ViewSet): """ CREATE, SELECT, UPDATE OR DELETE """ def retrive(self, request, pk): user = self.get_object(pk) print(user.query) user = TestSerializer(user) return Response(user.data) def list(self, request): users = TestTB.objects.all() print(users.query) serializer = TestSerializer(users, many=True) return Response(serializer.data) def create(self, request): serializer = TestSerializer(data=request.data) if serializer.is_valid(): serializer.save() return Response(serializer.data, status=status.HTTP_201_CREATED) return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) def update(self, request, pk): user = self.get_object(pk) serializer = TestSerializer(user, data=request.data) if serializer.is_valid(): serializer.save() return Response(serializer.data) return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) def destroy(self, request, pk): user = self.get_object(pk) user.delete() return Response(status=status.HTTP_204_NO_CONTENT) def get_object(self, pk): try: return TestTB.objects.get(pk=pk) except TestTB.DoesNotExist: raise Http404 api/urls.py router = routers.DefaultRouter() router.register(r'users', UserDetails, base_name='user-details') urlpatterns = router.urls This works fine with POST request to create new resource, GET request to get all resources, PUT request to update resource and DELETE request to delete resource. But how can I retrieve single resource? When I make request like http://127.0.0.1:8000/api/users/1/ than it shows error - { "detail": "Method \"GET\" not allowed." } It means that retrieve() method in UserDetails is never called.

Automatically Update Django Profile when creating user
I am fairly new to Django and am hoping that this is as easy as I think it should be. I have written a custom Django app that uses SaltStack as a back end for spinning up AWS instances. When an instance comes up, it adds the user who created it using their SSH key. I need to give each user a UID and GID so we can create user accounts on linux hosts for them. Right now, this requires that an admin go in for each new user created and manually update these fields in the admin interface before a user can use the tool. What I am hoping is that when a user is created, there is a way for Django to search through the profiles for the UID/GIDs that have already been used, increment by one, and assign it to the newly created user automatically. Here is my Profile model: class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) linux_username = models.CharField(max_length=50, blank=True) linux_uid = models.CharField(max_length=10, blank=True) linux_gid = models.CharField(max_length=10, blank=True) linux_ssh_authkey = models.TextField(max_length=1000, blank=True) @receiver(post_save, sender=User) def update_user_profile(sender, instance, created, **kwargs): if created: Profile.objects.created(user=instance) instance.profile.save() I hope this makes sense--when a user signs up, they choose a linux username … -

My urls.py has an entry: urlpatterns = [ url(r'^results/(?P<query>).+', views.ResultsView.as_view(), name="results"), ] which matches to the corresponding Class Based View: class ResultsView(TemplateView): template_name = os.path.join(APPNAME, "results.html") def dispatch(self, request, *args, **kwargs): query = kwargs['query'] print("HERE: " + str(json.dumps(kwargs, indent=1))) print(self.kwargs['query']) print(self.kwargs.get('query')) print(kwargs['query']) print(kwargs.get('query')) if query is None: return redirect('/') return super(ResultsView, self).dispatch(request, *args, **kwargs) def get_context_data(self, **kwargs): context = super(ResultsView, self).get_context_data(**kwargs) print("HERE: " + str(json.dumps(kwargs, indent=1))) print(self.kwargs['query']) print(self.kwargs.get('query')) print(kwargs['query']) print(kwargs.get('query')) ... # This is just here to test if 'query' is set def get(self, request, query): print(query) I'm trying to get the value of the query variable that is set in urls.py. However, after trying various solutions I found on other SO posts (as you can see from all the print statements), nothing is working. I'm fairly sure my urls.py is set up properly, because the request resolves to the correct page (results/), but all attempts to print the query entry of the dict return an empty string, and json.dumps(kwargs, indent=1)) prints this: HERE: { "query": "" } What am I doing wrong? -

Video output on browser created using python
I am working on a project with Python and I wonder if it is possible to display an output video embedded in a web page. Consider the code on the following section: Playing video from file. My idea was to replace cv2.imshow('frame',gray), to another command, maybe something with Django (other frameworks can be suggested!). Does anyone have any reference for me to start? PS.: each frame will be generated during execution, so it's not an option to save the video and upload it...
