How to return a group by query via Django REST API?
I have a Django REST API which works perfectly when I want to query some data from the database. Here I have an example: views.py class ProductListAPIView(generics.ListAPIView): def get_queryset(self): # Collect data from products table and filter it queryset = Product.objects.filter(name="Ferrari", date__lte="2022-08-01") # <- Substitute with line below return queryset serializer_class = ProductSerializer authentication_classes = [authentication.SessionAuthentication, authentication.TokenAuthentication] permission_classes = [IsOwnerPermission] serializers.py from rest_framework import serializers from insert_data.models import Product class ProductSerializer(serializers.ModelSerializer): class Meta: model = Product fields = ["name","category","date","price"] The output is what I expect i.e. a json response with the content of the database. The problems arise when I try to group the queryset in order to return the average price of a product. By doing some research in the internet I noticed that I just need to substitute the line of code in the views.py script with this: Product.objects.filter(name=params['name'], date__lte=query.date).values('name','category').annotate(price_average=Avg('price')).order_by() I am pretty confident that this does the work, however the API returns an error which I do not know how to fix: AttributeError: 'int' object has no attribute 'pk' I totally have no idea what this refers to. Would you be able to suggest a smart and elegant way to return the average price of a product … -

Django large CSV export with celery (async)
I am trying to export a CSV file which takes a while to generate. I have written the export CSV view which is successfully working, however I needed to adapt it to use celery for it to work in production with large data volumes. I have written the following code (mostly following https://thoslin.github.io/async-download-with-celery/): View: from tasks import export_report @staff_member_required() def export_status_report(request): task = export_report.delay() return render(request, "admin/poll_for_download.html", {"task_id": task.task_id }) # Check if task is finished def poll_for_download(request): task_id = request.GET.get("task_id") filename = request.GET.get("filename") if request.is_ajax(): result = AsyncResult(task_id) if result.ready(): return HttpResponse(json.dumps({"filename": result.get()})) return HttpResponse(json.dumps({"filename": None})) try: f = open("/path/to/export/"+filename) except: return HttpResponseForbidden() else: response = HttpResponse(file, mimetype='text/csv') response['Content-Disposition'] = 'attachment; filename=%s' % filename return response Task: @app.task def export_report(): date = datetime.now() date = date.strftime("%m/%d/%Y") filename = "reoport"+date+".csv" response = HttpResponse(content_type='text/csv') response['Content-Disposition'] = 'attachment; filename= "{}"'.format(filename) payouts = Payout.objects.all() writer = csv.writer(response) #instantiate writer # write headers writer.writerow(['Field1', 'Field2', 'Field3']) for payout in payouts: list = [payout.field1, payout.field2, payout.field3] writer.writerow(list) return filename HTML <script> $(function(){ $.ajaxSetup({ cache: false, timeout: 360000 }); var url = "admin/poll-for-download/"; var i = 0; (function worker() { $.getJSON(url+"?task_id=", function(data){ if(data.filename) { var file_url = url+"?filename="+data.filename; $("#content").html("If your download doesn't start automatically, please click … -

How can I paginate a dictionary inside my model?

django subclass not calling superclass (derived from modelform) clean method
I have a django form (formA) that inherits from modelform. In another app, I have a form that derives from that form (formB). This all works ok, including obtaining fields from the base class formA, but when the clean method is called, it doesn't call the formA clean method. Instead it skips formA, and calls django's modelform.clean. I can create a clean method in formB and this is called, but calling the super().clean() method also steps immediately into django's modelform.clean. Why might this be happening and what do I have to do to get the correct inheritance chain for the clean method? MTIA -
Django auth group permission handling
I use Django auth groups. The groups contain permissions(https://docs.djangoproject.com/en/4.1/ref/contrib/auth/#group-model). Now groups are assigned to users based on their actual role. In my test setup one group contains the permission (market.xyz). This group is assigned to the logged in user. In the debugger I see that the group permission is assigned (line 88) But if I call user.has_perm(per1) I get False (line 87) I can not make sense of this result. Is it necessary to activate the auth group mechanism? Do I have to add some additional Middleware? -
Django - analyze query execution time before it gets executed
I have a web interface(in django), through which I execute sql queries on different MySQL DB servers. Can we analyze query execution time(how much time it will take to return the result set) and the size of result set before it actually gets executed? I am using Django and MySQL DB. If cpu utilization is not much and the result set is in few KBs or bytes then query should get executed. -
Counting object views in a ListView
How is it possible to track how many times an object has been viewed if it is shown in a ListView? Imagine the Facebook feed, I want to know how many times users actually see each post on their feed, without opening it. My only thought so far is making an AJAX call for each post when it comes into the user's view, but that seems like it would be too resource heavy. Or should I aggregate the post views and only make the AJAX call once in a while with a list of posts that have been viewed? Or is there any other better way? (Doing it server-side is not ideal, because I want to know that a user actually read the post, so if they spent at least 2-3 seconds reading it). -

Can I navigate between iPad web applications running on different systems withou show the Safari's url address bar?
I’m a software developer and I developed a web application for iPad using Django. I have four embedded systems connected to the same network and each system run his web application. I added the apple meta-tags for the full-screen mode, which remove the url address bar of Safari. My problem is that i need to navigate between the system’s pages, but, when I load the page of another system, Safari show the address bar. There is a way to don’t show the address bar when I load a page from another system if it has the apple meta-tag too? I tried to automatically touch the screen on "done" to remove the bar on load, but i cannot find a way to persistent remove this bar. -

Django requests : response much slower than function itself
My application has performance issues (worsening during busy hours). I've noticed following strange behaviour : When I set up the django enviroment: os.environ.setdefault("DJANGO_SETTINGS_MODULE", "backend.settings.test") django.setup() and try to run the function itself: views.dataCheckFunction (9277 is entry parameter) for i in range(1,10): zac=datetime.now() views.dataCheckFunction(9227) kon=datetime.now() delta=kon-zac print(delta) It runs as expected and each run takes from 0.7s to 1s However when I try to call same function via for i in range(1,10): zac=datetime.now() views.dataCheckFunction(9227) res = requests.get(url='https://profiextra-test.generali.sk/api/policy/9227/dataCheckFunction/', headers={'Content-Type':'application/octet-stream'}) kon=datetime.now() delta=kon-zac print(delta) The duration of each call is very volatile and it can be from 2.3s to 10s The function makes approx 200 database calls. To reduce the traffic I use Memcache Any idea what can be the cause ? Thanks -

Customize group permissions in django?
I need to make role-based authentication. Firstly, I made group permissions for all my apps. I assigned some of them to role according to role's ability. from django.contrib.auth.models import AbstractUser from django.contrib.auth.models import Group class Role(models.Model): title = models.CharField(max_length=32) groups = models.ManyToManyField(Group) def __str__(self) -> str: return self.title Here you can a see driver role which has access on some group permissions (in fact they are just names of groups) Now I have a user model: class Users(AbstractUser): role = models.ForeignKey( Role, on_delete=models.CASCADE, related_name='roles', blank=True, null=True) def __str__(self): return (self.username) I don't want to pick group permissions every time when I created a new staff user. I just want to set a role to a user and it should automatically pick all permissions based on selected role's groups. How to customize groups in django models? -
Post a CharField to an ArrayField in from React to Django using Axios
I am trying to create a feature where if a user writes a post the ID of the post goes into an ArrayField in the User model so a list of their writing can be accessed. I introduced a new column in the User database, made the necessary migrations and trialed this feature just saving one post ID which worked fine. The issue arose when I made the model field an ArrayField. Now when I do the POST request I get an error response : "{\"posts_written\":{\"0\":[\"Expected a list of items but got type \\\"str\\\".\"]} Currently I am writing the REQUEST as let newPost = new FormData() newPost.append('title', title) newPost.append('content', content) updatePostList.append('posts_written', id + ',') await API.patch(`/profile/user/${loggedInProfile.id}/update/`, updateArticleList, { headers: { 'Authorization': `Token ${sessionToken}`, 'Content-Type': 'multipart/form-data', }, }) I am unsure of how to write the POST request to work with the ArrayField, I have looked online for answers but can't find anything. Here is the User model class User(AbstractUser): id = models.CharField(max_length=36, default=generate_unique_id, primary_key=True) username = models.CharField(max_length=250, unique=True) profile_image = models.ImageField(upload_to='profile_images', default='/profile_images/DefaultAvatar.png') bio = models.CharField(max_length=500, default='', blank=True, null=True) display_name = models.CharField(max_length=250, blank=True, null=True) articles_written = ArrayField( ArrayField(models.CharField(max_length=36, blank=True, null=True)), ) Thank you -
