How to get Id from CreateView in django
Hello all I need some help getting the id from an object in django I have a createView where I want to send an notification for the user when a new object is created, and I need the object Id... def form_valid(self, form): # setting fields that are not open to user form.instance.created_by = self.request.user form.instance.status = 'open' messages.success(self.request, 'Ticket Created Successfully!') Notification.objects.create( created_by=self.request.user, created_for=form.instance.responsible, title=f"New ticket from {self.request.user.first_name} {self.request.user.last_name} =====> {form.instance.id}", message=f"Hello",) return super().form_valid(form) The problem is that {form.instance.id} is always none. Anyone can help me with that? Thanks in advance -
Why do my javascript integration in a django template does not work?
I am really new to django and i am trying to build a small page where a chart with chart.js is shown. I want to load the javascript file static. I created a basic html-file called data_table.html and added a folder static where three files are in: data_table.js, styles.css and a picture bild.jpg. The html file is: {% load static %} <!DOCTYPE html> <head> <link rel="stylesheet" href="{% static 'styles.css' %}" type="text/css"> <script type="text/javascript" src="{% static 'data_table.js' %}"></script> <title>Data viewer</title> </head> <body> <canvas id="myChart" width="200" height="200"></canvas> <script> </script> <p class="text">Picture:</p> <br> <img class="img" src="{% static 'bild.jpg' %}" alt="My image"> </body> </html> The css file and the picture are loaded. The picture is displayed and with the css file i can resize the picture. So that works i guess? The javascripts file looks as follows: const ctx = document.getElementById('myChart').getContext('2d'); const myChart = new Chart(ctx, { type: 'line', data: { labels: [{% for d in data%}'{{d.label}}',{%endfor%}], datasets: [{ label: '# of Votes', data: [{% for d in data%}{{d.data}},{%endfor%}], backgroundColor: [ 'rgba(255, 99, 132, 0.2)', 'rgba(54, 162, 235, 0.2)', 'rgba(255, 206, 86, 0.2)', 'rgba(75, 192, 192, 0.2)', 'rgba(153, 102, 255, 0.2)', 'rgba(255, 159, 64, 0.2)' ], borderColor: [ 'rgba(255, 99, 132, 1)', 'rgba(54, 162, … -
Django export model to csv for ManyToManyField
Have a few tables for which I successfully built export to CSV, based on the Models. However, for one where I count the 'likes' for the news (posts) I'm getting nowhere. Here is my model: class News(models.Model): news_title = models.CharField(max_length=300) news_text = models.TextField(max_length=2000) news_author = models.CharField(max_length=150) news_date = models.DateField(default=now) likes = models.ManyToManyField(User, related_name='user_like', blank=True) @property def total_likes(self): return self.likes.count() Problem is, that I can print out to CSV all items from the model, but if I print "likes" I get duplicated (or more) rows in CSV. The reason is, that if News is liked by 3 users, I get 3x rows on CSV for each User and under "Like Count" column I get their IDs. What I would like to get instead is: 1x row per News with a total of likes for each news. and view.py @login_required def export_news(request): newss = News.objects.all() response = HttpResponse(content_type='txt/csv') writer = csv.writer(response) writer.writerow(["ID","Title","Author","Date","Text","Likes Count"]) for news in newss.values_list('id','news_title','news_author','news_date','news_text','likes'): writer.writerow(news) response['Content-Disposition'] = 'attachment; filename="News_list.csv"' return response Appreciate any help. Thx -

How to optimize loading millions of records in MongoDB with Django admin?
I have MongoDB with over 20 million records integrated with Django administration. Both services are running in k8s. I have already applied some of the optimisations below: Adding NoCountPaginator (disable counting) Indexing MongoDB Sorting queryset Also, I read about adding skip and limit is not recommended since it will make the performance even worse. But still, loading is extremely slow and frequently throws timeout errors. Here's the custom manager to get queryset: models.py class RuleDataManagerRemoved(DjongoManager): def get_queryset(self): event_horizon = datetime.datetime.now() - datetime.timedelta(days=180) return RuleDataQuerySet(model=self.model, using=self._db, hints=self._hints).filter(last_change__gte=event_horizon) The filtering happens with indexed field, so I think the impact is not critical here. admin.py @admin.register(models.ChangedProductSlugs) class ChangedProductSlugsAdmin(RuleDataAdmin): paginator = NoCountPaginator show_full_result_count = False list_display = ('old_category_slug', 'old_product_slug', 'new_category_slug', 'new_product_slug', 'tld', 'last_change', 'created_by', 'stav') list_filter = ('last_change', ('old_product_slug', SingleTextInputFilterOldProduct), ('old_category_slug', SingleTextInputFilterOldCategory), ('new_product_slug', SingleTextInputFilterNewProduct), ('new_category_slug', SingleTextInputFilterNewCategory), 'deleted', 'deleted_by', 'tld') search_fields = ('old_category_slug', 'old_product_slug', 'new_category_slug', 'new_product_slug') resource_class = resources.ChangedProductSlugsResource actions = ['restore_queryset'] def stav(self, obj): return not obj.deleted stav.boolean = True def changelist_view(self, request, extra_context=None): default_filter = False try: ref = request.META['HTTP_REFERER'] pinfo = request.META['PATH_INFO'] qstr = ref.split(pinfo) if len(qstr) < 2: default_filter = True except: default_filter = True if default_filter: q = request.GET.copy() q['deleted__exact'] = '0' request.GET = q request.META['QUERY_STRING'] = request.GET.urlencode() return super(ChangedProductSlugsAdmin, … -

Django DetailView count increases by 3 instead of 1

How to use _set in SerializerMethod for instance?

Django REST Serializer permanently changed in init
I'm facing a weird issue with DRF: I have several serializers for which I want to display certain fields only under specific conditions, such as url parameters there being in the request or the user having certain permissions. To decouple my serializer's presentation logic from the business logic, I decided to add a conditional_fields attribute to the serializer's Meta class: it's a dict in which the keys are strings representing conditions, such as "SHOW_HIDDEN_FIELDS" and their values are lists of field names that need to be removed if the key isn't present in the serializer context. Then I override my viewsets' get_serializer_context method to get the desired values inside of context. I made a remove_unsatisfied_condition_fields method which does the following: def remove_unsatisfied_condition_fields(self): conditional_fields = self.Meta.conditional_fields for condition, fields in conditional_fields.items(): if not self.context.get(condition, False): for field in fields: self.fields.pop(field, None) The serializers making use of it look like this: class ExerciseSerializer(serializers.ModelSerializer): class Meta: model = Exercise fields = [ "id", "text", "solution", "correct_choices" ] conditional_fields = { "EXERCISE_SHOW_HIDDEN_FIELDS": ["solution", "correct_choices"], } Here comes the problem: if I manually call this method inside my serializers, in their __init__ method, like this: def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.remove_unsatisfied_condition_fields() everything works fine. … -
