I am struggling to modify this view so that a chart is generated based on user input. The underlying isssue is that I cannot find a way to make this with Django rest framework. Here is what I have been able to do so far: view.py: class forecast(APIView): def get(self, request, *args, **kwargs): query = request.GET.get('search_res', None) if query and request.method == 'GET': reference = Item.objects.filter(reference = query) forecast1 = Item.objects.filter(reference = query).values('demand_30_jours') forecast2 = Item.objects.filter(reference=query).values('Lt2') forecast3 = Item.objects.filter(reference=query).values('Lt3') data = {'reference': reference, 'forecastdata':[forecast1, forecast2, forecast3]} return Response(data) urls.py urlpatterns = [ path('', HomeView.as_view(), name='HomeView'), path('items.html', ItemPage.as_view()), path('charts',TemplateView.as_view()), path('admin/', admin.site.urls), path('api/chart/data',ChartData.as_view()), path('api/chart/forecast',forecast.as_view()) items.html <form id="searchform" method="get" action="" accept-charset="utf-8"> Search <input id="searchbox" name="search_res" type="text" placeholder="Search"> <input type="submit" value="OK"> </form> <div class="col-lg-6"> <div class="card mb-4"> <div class="card-header"><i class="fas fa-chart-bar mr-1"></i>90 DAYS FORWARD FORECAST</div> <div class="card-body"><canvas id="myChart" width="150" height="116"></canvas></div> <div class="card-footer small text-muted">References</div> </div> </div> <script> $(document).ready(function() { var endpoint = '/api/chart/forecast' var forecastdata= [] var reference = [] ; $.ajax({ method: "GET", url: endpoint, success: function (data) { reference = data.reference forecastdata = data.forecastdata setChart() }, error: function (error_data) { console.log(error_data) } } ) function setChart(){ var ctx = document.getElementById('myChart').getContext('2d'); var myChart = new Chart(ctx, { type: 'scatter', data: { labels: reference, … -

How to create auto generate code in django
I have a company, department, and item list. in item list company and department are foreign keys. so when I add an item into the item list, item will generate a code for itself automatically like from company name's 3 alphabets, department name's 3 alphabets and 4 or 5 digits no. starting from 0001 and auto-increment. each company item will start from 0001. As an example: If a company is "ABCDE" and the department is "Finance" the code will be auto-generated like ABC-Fin-0001. is there any way to get these things done?

How to define django-imagekit ImageSpecFields in parent/mixin class?
I'm using django-imagekit to provide thumbnail versions of uploaded images on my Django models. I would like to define various thumbnail ImageSpecFields in a mixin that my models can then inherit. However, each model currently has a different name for the ImageField on which its ImageSpecFields would be based. I've tried this: from django.db import models from imagekit.models import ImageSpecField from imagekit.processors import ResizeToFit class ThumbnailModelMixin(models.Model): IMAGE_SPEC_SOURCE_FIELD = None list_thumbnail = ImageSpecField( processors=[ResizeToFit((80, 160)], source=IMAGE_SPEC_SOURCE_FIELD, format="JPEG", options={"quality": 80} ) class Meta: abstract = True class Book(ThumbnailModelMixin): IMAGE_SPEC_SOURCE_FIELD = "cover" cover = models.ImageField(upload_to="books/") class Event(ThumbnailModelMixin): IMAGE_SPEC_SOURCE_FIELD = "ticket" ticket = models.ImageField(upload_to="events/") But, as expected, this fails with: Exception: ThumbnailModelMixin does not define any ImageFields, so your list_thumbnail ImageSpecField has no image to act on. Is there a way to get inheritance like this to work? There are at least two other solutions: Don't use a mixin/parent, and include the ImageSpecFields on each child class - a lot of duplicate code. Change the Book.cover and Event.ticket fields to have the same name, like image and use "image" for the ImageSpecField source parameter. The latter sounds best, but I'm still curious as to whether there's a way to get the inheritance working? -
How to display chosen poll option alongside overall results in Django
I'm new to Python & Django and I have been following the App tutorial that the Django Documentation has. I have made the routes and everything is working, the issue I am having is that I want to be able to show what poll option the user chose on the result page. (The result page currently only shows the overall result of the poll, which I do want to keep but I also want to display the selected choice in addition to that.) The user does not have to be logged in so I haven't created a foreign key to tie a user to their vote. I figured out a way to add the selected choice primary key to the URL but as i'm using class based views i'm not sure how to get that value in the result view. urls.py ... app_name = "polls" urlpatterns = [ path('', views.IndexView.as_view(), name='index'), path('<int:pk>/', views.DetailView.as_view(), name='detail'), path('<int:pk>/results/<int:choice_id>', views.ResultsView.as_view(), name='results'), path('<int:question_id>/vote/', views.vote, name='vote'), ] ... views.py def vote(request, question_id): question = get_object_or_404(Question, pk=question_id) try: selected_choice = question.choice_set.get(pk=request.POST['choice']) ... #removed the test part else: selected_choice.votes += 1 selected_choice.save() return HttpResponseRedirect(reverse('polls:results', args=(question.id, selected_choice.id))) class ResultsView(generic.DetailView): model = Question template_name = 'polls/results.html' -

Django/Nginx: Restricting access to content on a subdomain
I have a Django app at www.mydomain.com that will be redirecting users to video streams on a subdomain meetings.mydomain.com.

Django - choose Choice value depending on view loaded
I have a (forms.form) class where I have choices. I wish to decide whenever I load view_1, that the choice for that view is choice_A, and then when I load view_2, that the choice for that view is choice_B. So depending on the view loaded the choice value changes accordingly. Class for CreateGameForm(forms.form) class CreateGame(forms.Form): game_choices = ([ ('choice_A', 'choice_A'), ('choice_B', 'choice_B') ]) game = forms.ChoiceField(choices=game_choices , required=True) I have tried to make it work with changing the initial value by adding one to the game, and then in def init adding it together with a function that changes the initial value when the view/URL_pattern changes, but without much luck. Any ideas? -

The code is below if request.method == 'POST': record_name = request.POST.get('recordname') record_date = request.POST.get('recorddate') record_generate_by = request.POST.get('recordgenerateby') record_description = request.POST.get('recorddescription') record_file = request.FILES.get('recordfile') record_image = request.FILES.get('recordimage') fs = FileSystemStorage if record_file is None: record_file = 'No File' else: fs.save(record_file.name , record_file) if record_image is None: record_image = 'No Image' else: fs.save(record_file.name , record_file) I used this API(FileSystemStorage) many times, but this time it shows error like this and already used this API in previous function and MEDIA_ROOT and MEDIA_URL is all set. The previous function stores file and image successfully, but this shows this kind of type error. Now what's the solution: The error is File "C:\Users\Mahad Akbar\PycharmProjects\FYP\Healthcare\myapp\views.py", line 754, in addnewRecord fs.save(record_file.name , record_file) TypeError: save() missing 1 required positional argument: 'content' [06/Apr/2020 17:15:28] "POST /addnewRecord HTTP/1.1" 500 72349 -
Django distinct count annotation not counting distinct
I am trying to annotate a queryset with a related object count, however it seems to be counting the same records multiple times even though I am passing the count=True flag: obj.some_set.annotate(rel_ct=Count('rel', distinct=True)).values('pk', 'name', 'pc') Problem: some results o.rel_ct returns a greater number than the real count o.rel_set.count(). I've tried ordering the original queryset to no avail. Not that it should matter because distinct=True should take care of that. -
