How to edit field how an embedded model in django
I have following models : ModelA --> with fields flda1, flda2, fld3 and id ModelB --> with fields fldb1, fldb2, id and a_obj = foreign-key-to-ModelA Now I have to write view to update flda1 and flda2 of ModelA and fldb1 of ModelB resources having foreign-key-to-same(ModelA) [some (not all) -- i.e., not all b_objs need to be modified ] The update data must be sent as follows : data = { 'flda1' : 'PRADEEP 2 title CHANGED', 'flda2' : 'medium CHANGED again...', "b_objs" : [ {'fldb1':'TB', 'modela':99, 'id':184}, {'fldb1':'STF', 'modela':99, 'id':185} ] } And the query parameter contains id for ModelA The problem is that the view and the serializer are working properly for flda1 and flda2. But when I add b_objs, I get errors. Here is my view : class ViewA(RetrieveUpdateDestroyAPIView): queryset = ModelA.objects.all().prefetch_related('b_objs') serializer_class = ModelASerializer def update(self, request, *args, **kwargs): modela_id = = request.query_params['id'] modela_ins = queryset.filter(pk=modela_id).first() serializer = self.get_serializer(project, data=request.data, partial=True) serializer.is_valid(raise_exception=True) serializer.save() And serializers are : class ModelBSerializer(serializers.ModelSerializer): class Meta : model = ModelB fields = '__all__' class ModelASerializer(serializers.ModelSerializer): obj_bs = ModelBSerializer(many=True) def validate(self, data) : # validation code return data def update(self, instance, validated_data): print(validated_data) for field, value in validated_data.items(): setattr(instance, field, value) instance.save() # … -

Can't get two elements to update while using Django and HTMX
I'm trying to create a car pool where I use HTMX in my Django project to make it work. The CarPool model consist of two FK. One FK is "City", and the other is "Car". I have it somewhat working. So within my two tables (one table with all the cars that have no city attached, and the other table displaying all the cars attached to the city that has been clicked), I'm able to use hx-post to add the car, and same to remove the car with the clicked city. But I don't get the lists to update after they are clicked. I have tried different ways of using hx-oob-swap but since I'm fairly new with both Django and HTMX I'm not sure where to exactly use it. See attached pictures. So picture "notclicked", the left table shows all cars with no city, and the right table displays cars with "Chicago" as a FK. notclicked Picture "clicked" I have now clicked on the car MMW 331 from the left table, and it adds it to the right table which is good, but then when I click on it, I want it also to be removed from the left table … -

Django Links & Buttons Click Issue: All clicks open in a new window
Since a number of commits, All clicks on buttons, links, submit buttons... open in a new window. Submitting forms does not work anymore, which means I can't test the last changes I've made, and the navigation is obviously broken. What's happening: Clicking on any button or link opens a new window/tab, as the target="_blank" attribute would have the links behave What's expected: Action after clicking on any button or link should instead stay on the same page, as the default target="self" link behavior... I have no real clue of where the issue might be coming from...: An incorect or closure? I've checked, rechecking... One of the libraries that remained after I uninstalled tailwind A fault in the django_browser_reload extension Something linked with django-unicorn ? Thank you for helping me fix this blocking issue... -

Simplest way to get Django errors emailed to
I have a Django Application hosted on Python Anywhere with a PostGre back end. Is there anyway I can get the errors that are normally added to the error log to sent to my email, so I can be quickly notified of error. I am familiar with writing simple middleware, but i don't understand Django well enough to know how to capture the errors that go to error-log file. -
How to serialize subprocess.popen()
This is follow-on to Return output of subprocess.popen() in webserver. I have a long running process that is kicked off by a Webserver call (running Django). I'm using subprocess.popen() to spawn the process. I figured out how I can save the stdout and retrieve it later. But since this is a long-running process, I want the client to be able to cancel it. But in order to do that, I need an instance of the popen() object. But it is not serialiable, so I can't store it in a database or anywhere else? Is there any other solution other that just storing it locally in a map in views.py? -
Cannot view Django application installed with helm on Minikube
I have packaged a custom helm chart and did helm install announcements /helm When I go to kubectl get pods and kubectl get deploy it shows the pods and deployments are up. However, when I try to go to the Service IP to see the application, it hangs. I then try to do the command given by the helm install: export SERVICE_IP=$(kubectl get svc --namespace default announcements-helm --template "{{ range (index .status.loadBalancer.ingress 0) }}{{.}}{{ end }}") And then I get the error: error: error executing template "{{ range (index .status.loadBalancer.ingress 0) }}{{.}}{{ end }}": template: output:1:10: executing "output" at <index .status.loadBalancer.ingress 0>: error calling index: index of untyped nil I'm very new to Helm and Kubernetes, so I'm not sure what to try to fix this. Any advice? -
