Django_tables2 in a tabbed html view with Charts.js?
so I'm trying to get Charts.js and django_tables2 in a tabbed view system where you can click on the different tabs to display dynamic data in either Charts.js or django_tables2, all in the same URL. So far I have Charts.js working the way I want it in one URL, I have Django_tables2 working the way I want it in another URL, and I have the HTML tabbed view system working along with an AJAX call. The part I'm struggling with is combining the Charts.js and djano_tables2 into one URL. Has anybody succeeded doing this before? I've hit so many walls trying to do this. I tried simply putting the code from data_list.html into my charts.html and restructuring my views but this lead me down a path of endless errors. I'm just really not sure how I could combine these two into one URL. This is my code so far: views.py # For initial rendering of HTML tabbed views and user input search fields @api_view(('GET',)) def ChartForm(request, *args, **kwargs): form = SearchForm(request.GET) context = { 'form': form } return render(request, "charts.html", context) # AJAX calls this view with new parameters, this view filters the results, returns JSON object class apiChart(APIView): def … -

(django) context data not rendering to html
I have a dropdown menu where the user can select the orderID of a taxi ride, and the total distance travelled for that specific order ID will be rendered to the html. The total distance is already in my MySQL database and only needs to be rendered to the frontend, but I'm calling the variable and its not working. I've managed to get it to print to the terminal, but it's showing on my html file and I'm pretty sure I'm calling the variable wrong. Everything else renders, just not {{ total_distance}}. Any pointers? views.py def home(request): # limit query results to first 50 orders just to maximise performance orders = Distance.objects.all().order_by("order")[:50] if request.method == "POST": # code only enters if statement when an item from the dropdown menu is selected print("POST") order_id_selected = request.POST.get("order_id_selected", None) if order_id_selected: start_lat = Distance.objects.values_list( 'start_lat').filter(order_id__exact=order_id_selected) start_long = Distance.objects.values_list( 'start_long').filter(order_id__exact=order_id_selected) end_lat = Distance.objects.values_list( 'end_lat').filter(order_id__exact=order_id_selected) end_long = Distance.objects.values_list( 'end_long').filter(order_id__exact=order_id_selected) total_distance = Distance.objects.values_list( 'total_distance').filter(order_id__exact=order_id_selected) print(order_id_selected) print(total_distance) return render(request, 'base.html', { 'orders': orders, 'dropdown_menu': order_id_selected, 'total_distance': total_distance, }) else: # current view defaults to else print("not working") return render(request, 'base.html', { 'orders': orders, }) base.html <div class="container"> <div class="row"> <div class="col-9"> <div class="order"> <br> <h2>View and calculate … -
Failing to Use Foreign Key in Django-Forms & Getting Errors

Counting. Django query optmization, Django ORM
can you tell me how to optimize these queries? What is the most efficient way? I want to render all values separately in a view. I attached the screenshot from django-debug-toolbar.

How can django-rest return a serializer error in the correct format for the frontend?
I don't like how django-rest returns a serialization erros JSON. For instance, if two fields are not provided in the request body, the default JSON response is the following: { "title": [ "This field is required." ], "contract_recipients_data": [ "This field is required." ] } I have read about custom exception handling, but I am not sure how can I flatten this error response. I would like for the error message to contain only a string so that my frontend app can handle it better ( how can the frontend handle this dynamic JSON? It seems difficult and not scalable). -

Visual Studio Code Django debugging breakpoints not triggered on Views and Templates
I am facing a debugging issue with VsCode where it's failing to trigger any type of breakpoints (standard or log), but specifically on View calls and Templates. Breakpoints in other parts of the Django project structure work correctly. For example in this code sample: class HomeView(TemplateView): template_name = "home/home.html" def get(self, request, *args, **kwargs): return render(request, self.template_name, {}) A breakpoint on template_name = "home/home.html" will be triggered successfully when the Class is constructed. However a breakpoint on return render(request, self.template_name, {}) will never trigger (I would expect it to trigger when the user navigates to the URL this class renders). A few things I have already tried: Disable all other VsCode extensions aside from Python, Jupiter, and Pylance Revert to a 4-month-old (I'll explain why 4 months below) version of VsCode, the Python extension, PyLance, and Django Creating a function-based view of the above (which also doesn't trigger the breakpoint) Create a brand new Django project (been able to reproduce this on a brand new project, and two other existing projects) The 4-month-old timeline was because the last time I was working with Django and debugging Views was about 4 months ago so figured I would try those versions.

Django - Limiting Selections Based on ManyToMany Association
Am a front end guy interface guy. Tried learning to program some time ago but gave up. Giving it another shot using Python/Django this time around. Going well. Been trying to overcome the following issue for the last few days. Tried applying possible solutions anywhere I could find them but no luck so far. I have a user model with a manytomany association with a region. A user can manage many regions. I have a site model where the logged in user can create a site and that site has a foreign key with one region. I am looking to limit the selections in the siteform drop down so it only shows the regions identified through the manytomany relationship on the user model. The form will be used on my sitecreate view. Absolutely any help that you can provide would be invaluable. I have no hair left. # users.models from worker.sites_projects.models import Region ... class User(AbstractUser): ... region = models.ManyToManyField( Region, blank=True ) # sites_projects.models ... class Region(models.Model): name = models.CharField("Region", max_length=25) class Site(TimeStampedModel): site_name = models.CharField("Site Name", max_length=200) ... region = models.ForeignKey( Region, ... ) # sites_projects.forms ... ... class SiteForm(forms.ModelForm): ... # region = forms.ModelChoiceField(queryset=Region.objects.all()) # def __init__(self, … -

Django Admin Inline Link to Specific Queryset?
Following the Django Polls app tutorial, you end up with 2 models as follows: class Question(models.Model): question_text = models.CharField(max_length=200) pub_date = models.DateTimeField("date published") class Choice(models.Model): question = models.ForeignKey(Question, on_delete=models.CASCADE) choice_text = models.CharField(max_length=200) votes = models.IntegerField(default=0) The Choice model can be registered with the Django Admin Site, but then you are browsing all Choice objects for all Question objects and this gets cumbersome very quickly. The Choice model could be inlined using InlineModelAdmin so that only related Choice objects appear directly on the Question change page. Though if the number of choices gets large, this can also get quite cumbersome. I'm wondering if there is instead a way to link to the list of related Choice objects from the Question page? -
Django Postgres Exclusion Constraint with ManyToManyField
I would like to use Django Exclusion Constraint with ManyToManyField. Unfortunatelly, so far my efforts were futile. This is my appointment model: from django.contrib.postgres.constraints import ExclusionConstraint from django.contrib.postgres.fields import DateTimeRangeField, RangeOperators class Appointment: patients = models.ManyToManyField(Patient, related_name='appointments' , blank=True ) datetimerange = DateTimeRangeField(null=False, blank = False ) doctor = models.ForeignKey(Doctor, related_name='doctor_appointments') class Meta: constraints = [ ExclusionConstraint( name='unique_doctor', expressions=[ ('datetimerange', RangeOperators.OVERLAPS), ('doctor ', RangeOperators.EQUAL), ], ), ExclusionConstraint( name='unique_patients', expressions=[ ('datetimerange', RangeOperators.OVERLAPS), ('patients', RangeOperators.CONTAINED_BY) ], condition= Q(is_archived=False) & Q(is_cancelled=False) ) ] Unfortunatelly this doesn't work. The first constraint that references the Doctor works perfectly, but the second one gives me this error during migration: return self.cursor.execute(sql, params) psycopg2.errors.UndefinedColumn: column "patient_id" named in key does not exist return self.cursor.execute(sql, params) django.db.utils.ProgrammingError: column "patient_id" named in key does not exist This has been bogging me for quite some time. Any help appreciated. -

Best way to query Django ORM to sum items by category per year (for time series)
Assume we have the models: class Category(models.Model): description = models.CharField(...) # Ex: 'horror', 'classic', 'self-help', etc. class Book(models.Model): category = models.ForeignKey(Category, ...) written_date = models.DateField(...) I want to make a query that will eventually get me the total number of books per category per year! Like so: { '2019-01-01': { 'horror': 2, 'classic': 1}, '2020-01-01': { 'horror': 2, 'classic': 1, 'self-help': 4}, ... } I was only able to come up with the following query: Book.objects \ .annotate(year=TruncYear('written_date')) \ .values('year', 'category__description') \ .order_by('year') \ .annotate(total=Count('id')) However this only gets me { { "category__description": "Horror", "year": "2019-01-01", "total": 2 }, { "category__description": "Classic", "year": "2019-01-01", "total": 1 }, { "category__description": "Horror", "year": "2020-01-01", "total": 2 }, ... } Is there any way to do this via ORM? Or I have to do this by manipulating the result directly? Thanks! -
Should small specific views be implemented with Function Based views or CBVs?
I'm developing an app in Django and would like to know what is the correct way to implement some small views that need to implement some specific function. I'm still a beginner and I've been using CBVs from the start but I'm not sure if I should use FBVs for this. I now need to implement some specific functions when integrating Stripe, for example, to reactive a canceled subscription or to upgrade a subscription and was wondering if I should use FBVs for this? If not, should I for example use the POST of class SubscriptionView(APIView): def post(self, request): # Make a new subscription... that I use to create a subscription and just check if the user is trying to reactive/upgrade with a parameter or something like that? -
Django: Making sure a complex object is accessible throughout multiple view calls
for a project, I am trying to create a web-app that, among other things, allows training of machine learning agents using python libraries such as Dedupe or TensorFlow. In cases such as Dedupe, I need to provide an interface for active learning, which I currently realize through jquery based ajax calls to a view that takes and sends the necessary training data. The problem is that I need this agent object to stay alive throughout multiple view calls and be accessible by each individual call. I have tried realizing this via the built-in cache system using Memcached, but the serialization does not seem to keep all the info intact, and while I am technically able to restore the object from the cache, this appears to break the training algorithm. Essentially, I want to keep the object alive within the application itself (rather than an external memory store) and be able to access it from another view, but I am at a bit of a loss of how to realize this. If someone knows the proper technique to achieve this, I would be very grateful. Thanks in advance!
