I think my django view is making 16 forms instead of 15
Frist of all sorry for my bad english but i'm french ! So my problem is that i've written a django view to configure my CompactRIO from a web page. I have written a form to display things like baudrate and stop bit and i have created a formset to display multiple forms at once ( so i can configure multiple connections at once ). But when i run configure it, it stops right after the configuration of the last connection. So i am able to configure all 15 connections, the code runs fine, and then it stops working and i crashes. I think that maybe it comes from the fact that i create 16 forms instead of the 15 i want but the web page prints 15 forms so i dont know. Anyway thank you for taking the time to read my problem ! So this is my view : def config(request): if request.method == 'POST': ConfigFormSet = formset_factory(ConfigForm) formset = ConfigFormSet(request.POST) if formset.is_valid(): for form in formset: if form.is_valid(): entete = form.cleaned_data['Entete'] liaison = form.cleaned_data['Liaison'] baudrate = form.cleaned_data['Baudrate'] dataBit = form.cleaned_data['choixDataBit'] parityBit = form.cleaned_data['choixParityBit'] stopBit = form.cleaned_data['choixStopBit'] activate = form.cleaned_data['activate'] print(liaison) print(baudrate) print(dataBit) print(parityBit) print(stopBit) print(activate) # ------------------ … -

How I can flatten many to many relationship using djnago serializer
I am new to Django. While I am try to implement serializer for many to many relationship I got problem.I want to serialize a many to many field and need to create a dictionary based on the nested object. models.py class ClassRoom(models.Model): name = models.CharField(max_length=10) def __str__(self): return self.name class Teacher(models.Model): name = models.CharField(max_length=50) def __str__(self): return self.name class Teacher(models.Model): name = models.CharField(max_length=50) def __str__(self): return self.name serializers.py class Student(models.Model): name = models.CharField(max_length=50) class_room = models.ForeignKey(ClassRoom, on_delete=models.CASCADE) teacher = models.ManyToManyField(Teacher) def __str__(self): return self.name class TeacherSerializer(serializers.Serializer): teacher_name = serializers.CharField(source="name", label="Teacher") class Meta: model = Teacher fields = ['name'] class StudentSerializer(serializers.Serializer): class_room = serializers.CharField(source="class_room.name") teacher = TeacherSerializer(many=True) student_name = serializers.CharField(source='name', label="Student") class Meta: model = Student fields = ['student_name', 'teacher', 'class_room'] views.py class HomeclassView(viewsets.ModelViewSet): queryset = Student.objects.all() serializer_class = StudentSerializer I got the response like this: { results: [ { "class_room": "Class 1", "teacher": [ { "teacher_name": "Maria" }, { "teacher_name": "sara" } ], "student_name": "John" } ] } But I am expecting the result in : { results: [ { "class_room": "Class 1", "teacher_name": "Maria", "student_name": "John" }, { "class_room": "Class 1", "teacher_name": "sara", "student_name": "John" }, ] } Please help me to achieve this.

Can't access Django's login page using Ingress. NodePort and LoadBalancer work fine
I have a django app which has been migrated to Kubernetes. Exposing the service with NodePort or LoadBalancer (AWS) works just fine, however when I'm using Ingress (nginx), it's not redirecting to the login page, and I always get an "authentication credentials were not provided" message. I had never used Ingress before, so maybe I'm missing something. apiVersion: networking.k8s.io/v1 kind: Ingress metadata: name: django-ingress annotations: nginx.ingress.kubernetes.io/rewrite-target: / spec: rules: - http: paths: - path: /app pathType: Exact backend: service: name: django port: number: {{ .Values.service.port }} the idea is that if I visit localhost/app/admin, it should go to localhost/app/login and back to localhost/app/admin. But such redirection is not done by Ingress. As I said, it's working with NodePort and LoadBalancer. For example, localhost:30000/admin will redirect to localhost:30000/admin/login and then upon signing in, the form will go back to localhost:30000/admin Any idea about what might be missing? -
Django filter().first() returning different result than get()

Other simple fields class Meta: ordering = ('skill', 'question_number') verbose_name = _('comment phrase') verbose_name_plural = _('comment phrases') An administrator reported that the model couldn't be updated in the Django admin. After saving, the Django admin would report that the model updated successfully, but when they refreshed the page the data was still out of date. I opened up a Django shell and investigate: In [3]: cp = CommentPhrase.objects.get(pk=10280) In [4]: cp Out[4]: <CommentPhrase: lorem ipsum> In [5]: cp.term2_past_tense Out[5]: '' In [6]: cp.term2_past_tense = "Test" In [7]: cp.save() In [8]: cp.term2_past_tense Out[8]: 'Test' In [9]: cp.refresh_from_db() In [10]: cp.term2_past_tense Out[10]: '' I further tried doing a queryset update(), and this had the same result.

Access local dockerized django project via ip without port
I got a small django project wich runs within a docker container and it is locally only (no need to expose it to the whole internet, just my office), but since it's a coporate project I want to give the persons who use it the possibility to access it via the ip address of host machine instead ip address:port (wich in my opinion is less readable). Being honest, I have no experience configuring nginx. This is my nginx config file (see it's a very simple configuration): client_max_body_size 10M; upstream web{ ip_hash; server web:8000; } server { location /static/ { autoindex on; alias /src/static/; } location /media/ { autoindex on; alias /src/media/; } location / { proxy_pass http://web/; } listen 8000; server_name localhost; } And my django image entry point: CMD ["sh", "-c", "python manage.py collectstatic --no-input; python manage.py migrate; gunicorn project.wsgi -b 0.0.0.0:8000"] Both containers expose to same port. -

How To Migrate IntegerField To ForeignKey
I have a legacy database I am migrating towards Django. I have model like this: class MyModel(models.Model): other_id = models.IntegerField() This is an existing table filled with valid data. I want to migrate to class MyModel(models.Model): newbie = models.ForeignKey( OtherModel, on_delete=models.CASCADE, db_constraint=False, db_column="other_id", ) However, the generated migration keeps insisting on adding the already existing field and than dropping it: python manage.py sqlmigrate app 0069 BEGIN; -- -- Add field -- ALTER TABLE `mymodel` ADD COLUMN `other_id` integer DEFAULT 1 NOT NULL; ALTER TABLE `mymodel` ALTER COLUMN `other_id` DROP DEFAULT; -- -- Remove field -- ALTER TABLE `mymodel` DROP COLUMN `other_id`; Is there a way to convince Django to treat the field as ForeignKey without this exercise? I'd like to avoid a need to --fake the migration. -

Following is the model, class Video(models.Model): VideoId = models.AutoField(primary_key=True) VideoName = models.CharField(max_length=100) FPS = models.CharField(max_length=100) TotalFrame = models.CharField(max_length=100) Duration = models.CharField(max_length=100) The API, @csrf_exempt def videoApi(request, id=0): if request.method == 'GET': video = Video.objects.all() video_serializer = VideoSerializer(video, many=True) return JsonResponse(video_serializer.data, safe=False) elif request.method == 'POST': video_data = JSONParser().parse(request) video_serializer = VideoSerializer(data=video_data) if video_serializer.is_valid(): video_serializer.save() return JsonResponse("Added Successfully!!", safe=False) return JsonResponse("Failed to Add.", safe=False) elif request.method == 'PUT': video_data = JSONParser().parse(request) video = Video.objects.get(VideoId=video_data['VideoId']) video_serializer = VideoSerializer(video, data=video_data) if video_serializer.is_valid(): video_serializer.save() return JsonResponse("Updated Successfully!!", safe=False) return JsonResponse("Failed to Update.", safe=False) elif request.method == 'DELETE': video = Video.objects.get(VideoId=id) video.delete() return JsonResponse("Deleted Succeffully!!", safe=False) URLs url(r'^video/$',views.videoApi), url(r'^video/([0-9]+)$',views.videoApi), serializers , class VideoSerializer(serializers.ModelSerializer): class Meta: model = Video fields = '__all__' JSON Input [{"VideoId": 2, "VideoName": "lol", "FPS": "1", "TotalFrame": "1", "Duration": "1"}] output , "Failed to Add." -

Retrieve and Manipulate media files in Django
I am making a system, where I will let users upload excel files, and then I am saving the file to the 'media' folder. I am able to do it till this stage.

Can anyone help Here is the code, I used for uploading the file in the 'views.py' file def index(request): context = {} if request.method == 'POST': uploaded_file = request.FILES['document'] # print(uploaded_file.size) # print(uploaded_file.name) path = settings.MEDIA_ROOT print(path) # print(uploaded_file.content_type) fs = FileSystemStorage() name = fs.save(uploaded_file.name, uploaded_file) context['url'] = fs.url(name) return render(request, 'index.html', context) -

Decoding (and equating) special characters with the Django REST framework SearchFilter?
I have implemented a Django Rest Framework SearchFilter in my backend, which for the most part works correctly. This is the code structure in views.py: class JobsViewSet(viewsets.ModelViewSet): queryset = Jobs.objects.all() serializer_class = JobSerializer filter_backends = [filters.SearchFilter] search_fields = ['^name', '^job_type'] The only remaining problem is that when sending get requests with a special character, for example the Swedish letter å, Django doesn't recognize that å is the same letter as Å only in lower case (as it does with for example a and A). In the GET calls from the front end, å gets converted to %C3%A5 for lowercase and %C3%85 for uppercase. This results in the search box not finding the jobs beginning with the letters åäö if the job title begins in uppercase (as in Återvinning). Does anyone know of a solution that makes the filter understand and equate uppercase and lowercase letters of special characters? Something along the lines of UTF-8 decoding? I have looked for answers both in the REST framework documentation and here on Stack Overflow, without any luck. New to Stack Overflow btw, I hope I'm doing the formatting correctly! -
not able to POST required data in django templates
I want to POST a form from my html to views.py in django, but I am not able do it. This is my html. This form should post the url of the downloaded image to the views.py function. {% for x in photo %} <a class="down" href="{{x.image.url}}" onclick="myfunc()" download="none">get</a> <form action="/image_info/" method="POST" id='dform'> {% csrf_token %} <input name='d_button' type="hidden" value="{{x.image.url}}"> </form> {% endfor %} This is my javascript function to submit form whenever the get link is pressed <script type="text/javascript"> function myfunc() { document.getElementById("dform").submit(); console.log('hello'); } </script> this is my views.py. This should take the image url from the form and display it in the new page. def show_image(): image_url = request.POST.get('d_button', None) return render(request, 'show_image.html', {'image': image_url) but my problem is that the form is not returning the url of the image that is clicked instead it is returning the url of first link. for example link1 link2 link3 link4 if I click on link3, it is downloading the image in link3 but POSTING the url of link1 This is a bit tricky to explain but this is the best I can. Thanks in adavnce.
