Django Chartit - Display values of each model instance separately
I'm using django-chartit to display results of a survey as a stacked pivot chart. Each column is a question, in which each element of stack is one of the choices for this question. The structure of the models (omitted the vars I think are irrelevant to the question): Survey: <omitted> Question: survey = ForeignKey to a Survey question_text = CharField Choice: question = ForeignKey to a Question choice_text = CharField votes = IntegerField I spent some time with the chartit's tutorial and I'm starting to doubt whether this is at all possible without some trick or additional Model. Unfortunately, I'm very new to Django. This is the view containing the chart: class Results(CreateView): template_name = 'surveys/results.html' model = Survey form_class = ResearcherCreationForm def create_chart_data(self, survey): all_choices = Choice.objects.none() for question in survey.question_set.all(): all_choices |= question.choice_set.all() data = DataPool( series=[{ 'options': { 'source': all_choices, 'legend_by': 'choice_text' }, 'terms': [ 'choice_text', 'votes', 'question__question_text' ] }] ) return Chart( datasource=data, series_options=[{ 'options': { 'type': 'column', 'stacking': True, 'stack': 0, 'xAxis': 0, 'yAxis': 0 }, 'terms': { 'question__question_text': ['votes']} }]) def get(self, request, *args, **kwargs): self.object = None survey_id = self.kwargs.get('survey_id') survey = Survey.objects.get(pk=survey_id) cht = self.create_chart_data(survey) return self.render_to_response({'chart': cht}) So far I only … -
Django: reference context variable in an {% if %} block
I'm working on a Django project and editing a base template which the rest of the views inherit from. I have a context variable generally in this format: context = { 'metadata': { 'data1': value, # etc }, 'data': { 'value1': True, 'value2': False, # etc }, } I've been trying to add tags based on if the values in 'data' are true/false like so: {% if data.value1 is True %} {% load some_module %} {% endif %} {% if data.value2 is True %} {% load something_else %} {% endif %} My problem is that even if data.value1 is False the template tries to load the packages in that if block resulting in broken pages. I can't figure out where i'm going wrong. Can you not reference context variables like that? Am i just using the if block wrong? Is there a better way to do this? -
Django Pagination with Ajax
I am trying to display an HTML table that is dynamically updating every 3 seconds. With some help, I managed to get this part working, however, once the database grows big, Pagination will be needed. Django-Pagination is fairly straightforward, but I am having troubles getting it to work with the additional Ajax complexity. I looked at the related SO questions, but they were either very old, or they had no answers. The code: index.html {% extends 'app/base.html' %} {%load staticfiles %} {% block body_block %} <div class="container" > {% if elements %} <table id="_appendHere" class="table table-bordered"> <tr> <th>A</th> <th>B</th> <th>C</th> <th>D</th> <th>User</th> <th>Date</th> </tr> {% for e in elements %} <tr> <td><a href="{{ e.A.url }}">{{e.A}}</a></td> <td><a href="{{ e.B.url }}">{{e.B}}</a></td> <td>{{ e.C }}</td> <td>{{ e.D }}</td> <td>{{ e.User }}</td> <td>{{ e.Date }}</td> </tr> {% endfor %} </table> {% else %} No data to display! <br/> {% endif %} </div> {% endblock %} <script> setInterval(function() { $.ajax({ type: "GET", url: "get_more_tables/", // URL to your view that serves new info }) .done(function(response) { $('#_appendHere').append(response); }); }, 1000) </script> views.py def paginate(input_list, request): page = request.GET.get('page', 1) paginator = Paginator(input_list, 10) elements = paginator.page(page) return {'elements': elements} def index(request): elements = ElementFile.objects.all().order_by('-upload_date') context_dict … -
Dynamic filter with Django in detail view
I have two models: rooms and holdings. Rooms is a list of rooms, and holdings is a list of things stored in those rooms. I would to have a detail page (with the generic DetailView) for each room, showing some information from the rooms model about that room and all the records in the holdings model that match that room. The first part was relatively easy, but I can't figure out how to filter the holdings and display the result on the detail page. Here's what I have so far: models.py class rooms(models.Model): room = models.CharField(primary_key=True, max_length=100, help_text='Room/storage area ID') location = models.CharField(max_length=100, help_text='Location', null=True) def __str__(self): return self.room def get_absolute_url(self): return reverse('room-detail', args=[str(self.room)]) class holdings(models.Model): id = models.IntegerField(primary_key=True) room = models.ForeignKey('rooms', on_delete=models.SET_NULL, null=True) contact = models.CharField(max_length=100, help_text='Contact', null=True) survey = models.ForeignKey('surveys', help_text='Survey ID, Cruise ID, FACS ID, or FAN', on_delete=models.SET_NULL, null=True) def __str__(self): return f'{self.room}, {self.contact}, {self.survey}' views.py class RoomDetailView(generic.DetailView): model = rooms def get_queryset(self): self.room = get_object_or_404(rooms, room=self.kwargs['room']) return holdings.objects.filter(room=self.room) def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['room'] = self.room return context rooms_detail.html {% extends "base_generic.html" %} {% block content %} <h3>Room Detail </h3> <p></p> <p><strong>Room: </strong>{{ rooms.room }}</p> <p><strong>Location:</strong> {{ rooms.location }}</p> {% endblock %} That gives me … -
Dynamically populate ChoiceField Select within Form/Formwizard
First of all, I did my homework and tried finding a similar question :). I have been trying things out for the last couple of hours, but to no avail. What I'm trying to do seems very simple. I have several forms in a Formwizard. In the first form I have a text-input. In the next step I have a FormSet (but this could also be a simple Form) that contains a forms.Select (dropdown). I want to show the value of the text-input in this dropdown. However, I just can't get it to work. This is my code: In forms.py: class FirstForm(forms.Form): first_point = forms.CharField( widget=forms.TextInput( attrs={ 'class' : 'form-control' })) class SecondStepForm(forms.Form): dropdown_select = forms.ChoiceField( widget=forms.Select( attrs={'class' : 'form-control' })) SecondStepFormSet = formset_factory(SecondStepForm, extra=5) In views.py: FORMS = [("firstform", FirstForm), ("secondform", SecondStepFormSet)] class FormWizardView(LoginRequiredMixin, SessionWizardView): template_name = 'test.html' def get_context_data(self, form, **kwargs): context = super(FormWizardView, self).get_context_data(form=form, **kwargs) if self.steps.current == 'secondform': data = self.get_cleaned_data_for_step('firstform') print(data) context.update({'dropdown_select': data}) return context def done(self, form_list, **kwargs): return None And in my html-file: {% block content %} <div class="row"> <div class="col-md-12"> <form action="" method="post">{% csrf_token %} <table> {{ wizard.management_form }} {% if wizard.form.forms %} {{ wizard.form.management_form }} {% for form in wizard.form.forms %} … -
common file to be translated for python program and a Django app
`I need to use a set of constants in both a Django application and a Python program. These constants includes string to translate.

unique constraints in django
I have a database in django that contains persons and roles. persons has a one-to-many relationship to roles. The problem is that roles doesn't have a unique constraint, for example person adam and david can be artists in roles but django creates two identical artists entries, but I want the same entry, i.e. adam and david should point to one entry. If I add unique to my role field than django says it should be one-to-one. Any ideas? part of model.py: from django.db import models from phonenumber_field.modelfields import PhoneNumberField # Create your models here. # possibillitas models here class Person(models.Model): mail=models.EmailField(default='yourname@gmail.com') firstName=models.CharField(max_length=200,default='firstname') lastName=models.CharField(max_length=200,default='lastname') phoneNumber=PhoneNumberField() streetAdress=models.CharField(max_length=200,default='streetAdress') zipcode=models.CharField(max_length=200) city=models.CharField(max_length=200,default='Göteborg') country=models.CharField(max_length=200,default='Sweden') def __str__(self): return "%s %s" % (self.firstName,self.lastName) class Meta: ordering = ('firstName','lastName') class Role(models.Model): role=models.CharField(max_length=200) # person=models.ManyToManyField(Person) person=models.ForeignKey(Person,on_delete=models.CASCADE) def __str__(self): return self.role class Meta: ordering = ('role',) class Name(models.Model): name=models.CharField(max_length=200) role=models.ForeignKey(Role,on_delete=models.CASCADE) def __str__(self): return self.name class Meta: ordering = ('name',) -
Django Rest Framework: how to use DynamicFieldsModelSerializer for excluding serializer fields
I have a serializer that is used in a couple of endpoints (generics.ListAPIView), but in one of them I need to hide a serializer field. I would prefer to not write a new serializer just to cover this case. Starting from DRF 3.0 we have dynamic fields for serializers (https://www.django-rest-framework.org/api-guide/serializers/#dynamically-modifying-fields), but I'm having some troubles to fully understand how to use them. I created this serializer: class TestSerializer(DynamicFieldsModelSerializer): user_req = UserSerializer(read_only=True) user_tar = UserSerializer(read_only=True) class Meta: model = TestAssoc fields = ("user_req", "user_tar") and this is my endpoint: class TestEndpointListAPIView(generics.ListAPIView): serializer_class = TestSerializer permission_classes = [IsAuthenticated] lookup_field = 'test_username' def get_queryset(self): return ... Now I need to hide the 'user_tar' field from the output, and according to the documentation I should instantiate the serializer with something like: TestSerializer(fields=('user_req')) but how should I do this inside my TestEndpointListAPIView? Should I override get_serializer_class? Thanks for the help -

server process that beats every second in Django
In my project, several users access the same page, and when the group is there, then a certain process on the server side needs to run and change a model field in the database every second. When they leave the page, the process must stop. I know that it's doable using Celery crontab function, but I wonder if there are more efficient or compact way of achieving the same result in Django? -

Passing a model's string parameter to URL with TemplateView
I am listing data from a search result matching the name parameter of my Model. For each result I have a link to the detail page with the key parameter (which is a string) passed in the url, Like this <ul> {% for x in results %} <li><a href = '/index/{{x.key}}'>{{x.name}}</a></li> {% endfor %} </ul> My url.py looks like this app_name = 'kpi' urlpatterns = [ path('login/index/search', views.SearchView.as_view(), name="search"), path('login/index/<slug:key>', views.EpicDetailView.as_view(), name="detail") ] And my views.py look like this: class SearchView(LoginRequiredMixin, TemplateView): template_name = 'KPI/search.html' def get(self, request, *args, **kwargs): self.q = request.GET.get('q','') self.results = Epic.objects.filter(name__icontains= self.q) return super().get(request, *args, **kwargs) def get_context_data(self, **kwargs): context = super(SearchView, self).get_context_data(**kwargs) context['results'] = self.results return context class EpicDetailView(LoginRequiredMixin, TemplateView): template_name = 'KPI/epic_detail.html' def get_context_data(self, **kwargs): context = super(EpicDetailView, self).get_context_data(**kwargs) context['lone_epic2'] = Epic.objects.get(key=self.kwargs['key']) I know I am missing a step here, probably how i created the url path, or needing logic in my views.

How to use if statement inside a block in Django for image retrieval
I'm stuck. I have been trying to use all of my google fu to find this answer, but can't find it asked or answered anywhere. This is one of my first projects that I am trying to do not following a tutorial, so I apologize for my ignorance ahead of time. I am building my first blog and am trying to add a feature to display an image in the article. The problem is, I only want it to display if there is an image, as not all of them will have images. I can get the image to display, but if I go to an article without one, it gives me an error saying that it can't find the image. I thought I would try to do an if statement, but I am getting an error there as well and am not sure if I am doing the statement incorrectly (which is my guess) or not. #models.py from django.db import models from datetime import datetime # Create your models here. class Post(models.Model): title = models.CharField(max_length=200) body = models.TextField() created_at = models.DateTimeField(default=datetime.now, blank=True) image = models.ImageField(upload_to='blog/', null=True, blank=True) def __str__(self): return self.title #view.py from django.shortcuts import render from django.http import … -

i have two models which are truck and order and they have a relationship. from django.db import models from django.contrib.auth.models import User class Truck (models.Model): truck_number = models.CharField(max_length=200); condition = models.CharField(max_length=20); insurance = models.CharField(max_length=20); gps_tracking = models.CharField(max_length=20); owner_name = models.CharField(max_length=20); id_number = models.IntegerField(); telephone_number=models.IntegerField(); driver_name=models.CharField(max_length=30, default=None); driver_id_number=models.IntegerField(); driver_phone_number=models.IntegerField(); driving_license=models.CharField(max_length=20); good_conduct=models.CharField(max_length=30); def __str__(self): truck_number = self.truck_number return truck_number class Order(models.Model): truck_number= models.Foreignkey(Truck,related_name='relation_truck') date= models.DateField() product=models.CharField(max_length=30) depot = models.CharField(max_length=10) volume = models.CharField(max_length=30, blank=True) volume_delivered = models.CharField(max_length=30, blank=True) driver_name=models.ForeignKey(Truck, max_length=30,default=None) driver_id_number=models.ForeignKey(Truck, related_name='relation_id') driver_phone_number=models.ForeignKey(Truck, related_name='relation_tel') order_status = models.CharField(max_length=50, blank=True) def __str__(self): truck_number = self.truck_number return truck_number all the fields with foreign keys are fetching the whole object Truck but not the specific value of the foreign key. like i want truck_number in Order to fetch truck_number only from table Truck and not the whole Truck object. how can i get the foreign key values instead of the the whole object. -
IE 11 - Django based views issue
I have a Django app, and I'm using class-based views in some parts of it. When I try to access to these views on IE 11 it downloads the html instead of rendering it. I've searched the web and found this other posts talking about the same problem: https://www.reddit.com/r/django/comments/74r2af/django_not_working_with_internet_explorer/ Django: internet explorer download page content instead render it IE 11 Downloads Page instead of opening it, works in Chrome and Firefox According to this is some rendering issue caused by a wrong definition of the context, but my view looks like this: class BaseContentMixin(ActiveLoginRequiredMixin, TenantHasRolePermMixin, TenantActiveNotExpiredMixin, TenantHasPermMixin, SetDefaultTimezoneMixin): """ Attributes: content (str): content name, i.e 'training'. content_type (str): content type, 'shared' or 'custom'. permission (str): permission, i.e 'TRAININGS'.

Getting the HTML ID of a ModelForm in Django Views
So I start with a list of objects X (dynamic size), and for each X object I create a row on my template with a form to post a different model Y. However, if/when a user decides to post a Y object, I want to then update X's foreign key to point to the newly created Y object. The problem is, I can't figure out a good way to retrieve X's id. My question is about one way I thought of, but I would love other suggestions: Each form for creating Y has an ID (ie, in HTML) that has the X id in it. Is there a way in my django view to do something like this: if request.method == 'POST': video_element_form = VideoElementForm(request.POST, request.FILES) if video_element_form.is_valid(): print('form id: ' + $(#video_element_form).id); so that I can parse the id out of it? I know this isn't ideal but it seems really hard and I don't want to change the infrastructure if I don't have to, its quite fleshed out and this is the only problem I think is present.
