How can I get related objects for related objects of an object in Django in a single query when all linked using Generic Foreign Key
Assuming I have the following models and knowing that each Message can have multiple Records and each Record can have multiple Notes, how can I get a queryset of related Notes from a Message in a single query? class Note: content_type = models.ForeignKey(ContentType, on_delete=models.CASCADE) object_id = models.PositiveIntegerField() content_object = GenericForeignKey('content_type', 'object_id') class Record: content_type = models.ForeignKey(ContentType, on_delete=models.CASCADE, null=True) object_id = models.PositiveIntegerField(null=True, blank=True) content_object = GenericForeignKey() notes = GenericRelation(Note, related_query_name='records') class Message: records = GenericRelation(Record, related_query_name='messages') I know how to achieve this by using list comprehensions like shown below, however it is a bad approach since this will do multiple queries. if records := message.records.all(): notes = list(chain.from_iterable([record.notes.all() for record in records])) -

Use parameters in subfields with graphene-django without relay for pagination purpose
I'm using graphene with django and I'm struggling to do something that in my head should be very simple, but I don't find it documented anywhere in graphene docs or github nor did I see similar question here. The closest to it I found was: https://www.howtographql.com/graphql-python/8-pagination/ but as you can see I'd have to declare the parameters in the parent resolver which I don't want to. I have a query like this getUser(id: $userIdTarget) { id username trainings{ id name sessions{ id name } } } } I would like to implement a pagination in the sessions subfield. So this is what I would like: getUser(id: $userIdTarget) { id username trainings{ id name sessions(first:10){ id name } } } } and in the resolver I'd implement something like this: def resolve_sessions(root, info, first=None, skip=None): if skip: return gql_optimizer.query(Session.objects.all().order_by('-id')[skip:], info) elif first: return gql_optimizer.query(Session.objects.all().order_by('-id')[:first], info) else: return gql_optimizer.query(Session.objects.all().order_by('-id'), info) (gql_optimizer is just an optimization wrapper library I use) However this doesn't work as the field sessions correspond to a list of a model Session that is a fk to Training according to my django models, so this is automatically resolved by graphene because these types are DjangoObjectType , so I'm not … -

How to dynamically remove forms from an unbound formset without JavaScript in Django
I have a solution, but it contains one problem. I know where the problem is happening in the code, but I can't solve it. Maybe someone has a better solution that doesn't contain any problems. Description of the problem: After deleting any form, the fields in the remaining forms are not pre-filled if the data is not valid. Procedure: The browser displays 5 forms. The first field of the first form contains invalid data. I activate the delete check-box in the last form and click on the "delete" button. The last form is deleted and the first field of the first form is not pre-filled.

I want to generate pdf in my django project. I use pdfkit module to convert html page as a pdf file. I use this function but it has errors, like: OSError Exception Value: No wkhtmltopdf executable found: "b''" If this file exists please check that this process can read it or you can pass path to it manually in method call, check README. Otherwise please install wkhtmltopdf - https://github.com/JazzCore/python-pdfkit/wiki/Installing-wkhtmltopdf def customer_render_pdf_view(request, *args, **kwargs): pk = kwargs.get('pk') customer = get_object_or_404(Person, pk=pk) enrolment = get_object_or_404(Enrollment,pk=pk) template_path = 'test.html' context = {'customer': customer, 'enrolment':enrolment} template = get_template(template_path) html = template.render(context) pdf = pdfkit.from_string(html, False) response = HttpResponse(pdf, content_type='application/pdf' ) response['Content-Disposition'] = 'filename= "report.pdf"' return response -
Connect Angular Frontend to Django View
I have a basic django app that simply uploads an excel file onto an oracle database. I created a python class (uploader) to carry out some the sanity checks on the file and upload to the database. I have managed to successfully create a UI using HTML in Django templates which works fine. However, I wanted to migrate the front end to an Angular front end. I have created the angular app but I am currently struggling to understand how to connect the front end to django. Having researched online, they advise using models, serializers but because I carry out the upload through a standalone python class, I am not sure how to connect the two using this method. I assume I have to use a HttpClient to somehow connect to this view? Any help will be greatly appreciated. Thanks upload/views.py def clickToUpload(request): if request.method == 'POST': if 'form' in request.POST: try: upload_instance = uploader(request.FILES['file'], request.POST['date']) _ = upload_instance.run_process('File', update_log=True) message= "Success" except Exception as e: upload_message = 'Error: ' + str(e) return render(request, 'Upload/upload.html', {'upload_message':upload_message}) -
ModelForm doesnt render input fields properly
I have the following ModelForm: class RaiseTender(forms.Form): """ A form to raise a new tender for new facilities """ country = forms.ModelChoiceField(queryset=OperatingCountries.objects.all(), required=True) publisher = forms.ModelChoiceField(queryset=Company.objects.exclude(name='exclude-all')) class Meta: model = FacilityTender fields = ['publisher', 'amount', 'currency', 'country', 'start_date', 'end_date'] # Model class FacilityTender(models.Model): """ Class to store Facility Tender """ publisher = models.ForeignKey('company.Company', on_delete=models.CASCADE) publish_date = models.DateTimeField(auto_now_add=True) amount = models.FloatField() currency = models.CharField(max_length=3) country = models.CharField(max_length=50) start_date = models.DateTimeField() end_date = models.DateTimeField() submissions = models.IntegerField() is_active = models.BooleanField(default=True) is_closed = models.BooleanField(default=False) is_successful = models.BooleanField(default=False) # Checks how long is left for the tender period, # Assumes a 7 day tender duration @property def time_remaining(self): return self.publish_date + timedelta(days=7) def __str__(self): return F"{self.publisher} tendered {self.amount} {self.currency}" Now in my my view I do the following: def raise_tender(request): if request.method == 'GET': # Get the user instance user = User.objects.get(username=request.user.username) # Query companies associated to the cash pool of the requesting user companies = Company.objects.filter(cashpool__company=user.company) # Override the RaiseTenderForm company field RaiseTender.base_fields['publisher'] = forms.ModelChoiceField( queryset=companies) # Return the form form = RaiseTender() # Process inputs on POST request else: .... But for whatever reason the form only renders the fields where I provide a queryset to pre-populate. It's not the case with … -
Get the instance of related model and save
I need to create and save with the related model. My model looks like Class Abs(models.Model): detail = models.ForeignKey(Detail, ........) class Detail(models.Model): user = models.ForeignKey(get_user_model(), ...) detail_parts = models.ForeignKey(Abs,....) What I want to achieve is to create a new A and retrieve its instance and create a new Detail with user and detail_parts (related to model Abs) inside view class AView(viewsets.ModelViewSet): def create(self, request, *args, ** kwargs): detail = request.data.get(detail) // a = A.objects.filter(detail=detail) // here it return integer(example 20) Detail.objects.create(user=user,detail_parts=a) // returns Detail.detail_parts must be a "Abs" instance Any ideas ?
