How to update a model which contains an ImageField in django rest framework?
I need help updating a model that contains an ImageField with django rest framework (3.12.4). I've checked many questions related to this, but none seem to fix the problem. models.py class Image(models.Model): title = models.CharField(max_length=200, unique=True) image = models.ImageField(upload_to="images/") def delete(self, *args, **kwargs): self.image.delete() super().delete(*args, **kwargs) serializers.py class ImageSerializer(serializers.ModelSerializer): class Meta: model = Image fields = ['id', 'title', 'image'] views.py class ImageViewSet(viewsets.ModelViewSet): serializer_class = ImageSerializer queryset = Image.objects.all() parser_classes = (MultiPartParser, FormParser) def create(self, request, *args, **kwargs): file_serializer = ImageSerializer(data=request.data) if file_serializer.is_valid(): file_serializer.save() return Response(file_serializer.data, status=status.HTTP_201_CREATED) else: return Response(file_serializer.errors, status=status.HTTP_400_BAD_REQUEST) This way I can add a new image. The file is successfully added to images folder and the fields are serialized correctly. I can also delete created image, removing the file from images folder and instance from database. However, when I access the instance, I am unable to modify it without reloading the file; so if I want to change the title, I have to reload the file again and then make the request. Is there any way to update a model that contains an ImageField in django rest framework? -

django bootstrap alert: message alert showing forcefully in django
i am writing a function that would allow users chat with freelancers but now it keeps popping up a messages alert when i open up a new chat with another user. i would provide a screenshot below, and that is because it is not throwing any errors, but forcefully showing alerts. i have some ideas why it would be doing that and that is because django messages uses message.success(request, ...) etc. and in my function i have a lot of variables named message = ..., the problem now is that i do not know the particular message varible that i am going to rewrite.

201 Created - but no new object in SqLite database
I have a button that users can click on to add an object to their account. It's sent through django to my sqlite db, and in the console log there are no errors. It says "201 Created", and yet there is no new object in the database. Someone else had the same problem as me, the solution was getting rid of some methods in the serializer, but they don't specify what they got rid off. What's causing this? Here is my serializer: class RatSerializer(FlexFieldsModelSerializer, serializers.ModelSerializer): name = serializers.CharField() user = serializers.CharField(source='user.username', required=False) userid = serializers.CharField(source='user.id', required=False) body_colour = BodyColourSerializer() eye_colour = EyeColourSerializer() image = ImageSerializer(required=False) class Meta: model = rat exclude = ['bio'] def create(self, data): request = self.context.get("request") user = request.user return rat( name = data["name"], body_colour = BodyColour(name=data["body_colour"]["name"]), eye_colour = EyeColour(name=data["eye_colour"]["name"]), image = Image(), user = user) My views: class ratViewset(ModelViewSet, APIView): serializer_class = RatSerializer # queryset = rat.objects.all() def get_queryset(self): user = self.request.user if user.is_anonymous: return rat.objects.all() return rat.objects.filter(user=user.id) def post(self, request): rat = request.data.get('rat') # creates rat with the above data serializer = RatSerializer(data=rat) if serializer.is_valid(raise_exception=True): serializer.save() print(serializer.data, type(serializer.data)) return Response(serializer.data, status=status.HTTP_201_CREATED) return Response(serializer.errors, status=status) Grateful for any help! -
django rest framework trigger goes in loop on network delay
1: I am working with django rest framework as backend and angular as frontend. I am using signals and receiver of django at many places in my project. on pre_save or post_save method i am facing a common problem.

If response is fast in that case it works fine. 2: we have two models on two server, once coupan is created on pre_save or post_save i need to create another record say in beneficiary model. as i am indicating in these two models. if Beneficiary returns acknowledge quickly than it works fine. but again in case of network delay Coupan creates multiple records. class Beneficiary(models.Model): name = models.CharField(max_length=50) coupon_code = models.ForeignKey(coupon, on_delete=models.CASCADE) miscValue = models.TextField(blank=True, null=True) def __str__(self): return self.name class coupon(models.Model): sl_no = models.CharField(max_length=50) @receiver(post_save, sender=coupon) def save_profile(sender, instance, **kwargs): Beneficiary.objects.create(name="added from reciever", coupon_code=instance) 3: In test environment this works fine as we work on LAN, but once it … -

Best wat to implement action button in django
I'm writing a Django app that has an action button called restart. When clicked this button should restart a service. The problem is how would I implement this I have the option to add some JavaScript to the button and call the public rest API that's contained inside the Django app. Would that be the way to go? And how can I add an endpoint to the rest API? The endpoint would look like this /API/v1/services/service_name/restart -
Python/Django "page not found" error: "The current path, ... , didn’t match any of these."
I'm learning Chapter 18 in Python Crash Course by Eric Matthes. I am using Django 4.0.1 and the book uses is 2.2.0 so I see that other people are having similar issues as me with this section. In other similar stackoverflow questions on this issue, proposed solutions using url instead of path seem also outdated. The solutions on the website therefore are unfortunately not helping me. Problem: when I open http://localhost:8000/ and I click on "topics" I get the 404 not found error as follows: Page not found (404) Request Method: GET Request URL: http://localhost:8000/(%25%20url%20'learning_logs:topics'%20%25%7D Using the URLconf defined in learning_log.urls, Django tried these URL patterns, in this order: admin/ [name='index'] topics/ [name='topics'] The current path, (% url 'learning_logs:topics' %}, didn’t match any of these. However, navigating manually to http://localhost:8000/topics shows me the page as intended. I believe this is an issue due to my urls.py located in my app folder. Here is my urls.py in learning_logs (app), where I think the issue lies: from django.urls import path from . import views app_name = 'learning_logs' urlpatterns = [ #Home page path('', views.index, name='index'), #Page that shows all topics. path('topics/', views.topics, name='topics'), ] Here is my urls.py in learning_log (main project): … -

django rest framework and swagger : invalid literal for int() with base 10: 'None'

Django template websocket URL tag
I am trying to load ws_urlpatterns to template with tags: routing.py from django.urls import path from .consumers import WSConsumer ws_urlpatterns = [ path('ws/some_url/', WSConsumer.as_asgi(), name="ws"), ] <div class="container"> <div class="row"> <div class="col-6 mx-auto mt-5"> <h1>{{ text }}</h1> </div> </div> </div> <script> let socket = new WebSocket('ws://localhost:8000/ws/some_url/'); const h1 = document.querySelector('h1'); socket.onmessage = function(event){ let data = JSON.parse(event.data); h1.innerText = data.message; } </script> I tried let socket = new WebSocket("{% url 'ws' %}"); but I got Reverse for 'ws' not found. 'ws' is not a valid view function or pattern name. I am new to Django channels, will be very glad if you can give me a hand. -
How interdependent db calls handled in transaction.atomic
I have two DB calls inside the transaction.atomic() Sample codes with transaction.atomic(): result1, created = SomeModel.objects.get_or_create(**somedata) if not created: flag = SomeOtherModel.objects.filter(somemodel=result1).exists() if flag: result1.some_attr = value1 if flag else value2 result1.save() AFAIK about the transaction.atomic when my python codes do not cause an exception, so all the DB calls will be committed on the database. If any of the exceptions raised inside the block, no database operation will be committed to the database. So how is this thing handled when the DB call of one is used in the python logic to make other DB operations? Didn't find this species in the documentation, if any good source, please mention it.
