Django Rest - testing api delete
Currrently I am testing my django rest api, but I am stuck on delete method. My url looks like this path('books/shelfs/<int:shelf>/readers/<int:pk>/', views.ReaderViewSet.as_view( {'get': 'retrieve', 'delete': 'destroy', 'patch': 'partial_update'}), And My ViewSets looks like this def destroy(self, request, pk=None, *args, **kwargs): if request.data.get("book_type") is None: raise ParseError(detail="book_type is required, options are : 'global, non-global'") try: instance = self.get_object() user = self.request.user serializer = self.get_serializer(self.get_object()) ....... self.perform_destroy(instance) except Http404: pass return Response(status=status.HTTP_204_NO_CONTENT) And my test case is this def test_book_delete(self): # check if delete works book_type = {'book_type': 'global'} response = self.client.delete("/api/v1/books/shelfs/{}/" "reader/{}/".format( 1, 2), data=book_type) self.assertEqual(response.status_code, 204) But its alway 415 error The question is, how to pass this book_type in delete ? -
dynamically adding series to highcharts
I'm relative new to highcharts so I'm not that knowledgeable. But what I am trying to do is that I am trying to dynamically create series with a name and some x, y values. To get the x and y values I use two dictionaries looking like this: The X values. They are dates The Y values. They are seconds What I want to do is create a series that have the names of the keys and then they can have multiple points for x, y values. So for example at "Fiber_Mätning" I have two values in the key in both dictionaries. What I want to do is that I create a series with the name "Fiber_Mätning", and then it should have two points where I give both x and y value. So the 1st point in "Fiber_Mätning" would be x:"2020-10-28" y:"28800" and the 2nd point in "Fiber_Mätning" would be x:"2020-10-29" y:"18000" After that I would move on onto the next key in both dictionaries and do the same. So the way I create the series need to be a function that is dynamically creating series and the points depending on the amount of keys and values in the dictionaries. … -
Making API request using React
I am building a "Yahoo Finance" clone and I am having trouble fetching the users data from my own API and displaying it using React components. I have tested the API route itself and it works fine, however when trying to fetch the data from within the React component, the request is never made. (I know this because I added the line for printing "Data fetched" in order to verify) views.py: @login_required def dashboard(request): return render (request, "holdings/dashboard.html") def user_holdings(request): user = Profile.objects.get(user=request.user) positions = user.positions.all() data_response = {} data_response["holdings"] = [] for position in positions: position_data = {} position_data["symbol"] = position.symbol response = requests.get("https://www.alphavantage.co/query?function=OVERVIEW", params={"symbol": position.symbol, "apikey": "4JU2DZ6Q8876MFXK"}) data = response.json() name = data["Name"] position_data["name"] = name response = requests.get("https://www.alphavantage.co/query?function=TIME_SERIES_DAILY", params={"symbol": position.symbol, "apikey": "4JU2DZ6Q8876MFXK"}) data = response.json() price = data["Time Series (Daily)"]["2020-10-28"]["4. close"] position_data["price"] = price data_response["holdings"].append(position_data) print("Data fetched") return JsonResponse(data_response, safe=False) dashboard.html: <div id="app" /> <script type="text/babel"> class App extends React.Component { render() { return ( <UserHoldings /> ); } } class UserHoldings extends React.Component { constructor(props) { super(props); this.state = { error: null, isLoaded: false, items: [] }; } componentDidMount() { fetch("http://127.0.0.1:8000/user_holdings") .then(res => res.json()) .then( (result) => { this.setState({ isLoaded: true, items: result.holdings }); }, // … -
Bundle and Minify CSS and JS for plotly dash
I am using this package for using plotly dash for Django in one of my projects. django-plotly-dash The website I am working on expects heavy traffic and the scaling of the web app is very important for the client. Dash applications in Django are being served in an iframe and there are pages where I have multiple iframes and dash applications rendered on a single page. These iframes take ages to load due to all CSS and javascript files they are loading which is not a good user experience. I did R&D and a lot of googling but could not find a good resource in any of the forums on how can I use bundled and minified CSS and javascript files with plotly-dash. Any suggestion related to plotly-dash or Django-plotly-dash is welcome. Note: Packages used to minify and bundle Django static files will not work with this scenario as I do not control the javascript and CSS files being loaded in the dash application plotly dash handles it. (Or let me know if I am wrong.) -

How to update a ManyToManyField in Django using Ajax
I am working on an app that allows users to track workouts they do at the gym. I would like the user to be able to select an area of the body they want to focus on, which will then link to a list of specific exercises. The user will be responsible for creating all the data themselves. The problem I am having is that I want to apply ajax to my forms so that the data is added without a page refresh. At the moment I am about half way there... I have an area model, and an exercise model: models.py: class Exercise(models.Model): name = models.CharField(max_length=100) class Area(models.Model): name = models.CharField(max_length=100) exercise = models.ManyToManyField(Exercise) I have a view and a template which allow the user to create an area they want to work on. The ajax code I have written for this section is working how I would like. views.py class AreaList(View): def get(self, request): form = AreaForm() areas = Area.objects.all() return render(request, 'tracker/areas.html', context={'form': form, 'areas': areas}) def post(self, request): form = AreaForm(request.POST) if form.is_valid(): new_area = form.save() return JsonResponse({'area': model_to_dict(new_area)}, status=200) else: return redirect('tracker:areas') areas.html: <form id="addAreaForm" method="post" data-url="{% url 'tracker:areas' %}"> {% csrf_token %} {{ form … -

geodjango leaflet map not showing
I'm playing with Django and leaflet since a short time. It's fun, most the time, but frustrating, sometimes... Right now I'm having trouble displaying a leaflet map on my django front-end website, using a detailView and a template only. I've been looking for a solution since days and I couldn't manage it by my own, so here I am. I have no error, the container just shows blank, as if it couldn't call one of the embeded scripts properly : Here are the installed apps in my settings.py : INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'leaflet', 'django.contrib.gis', ] Here is my base.html : <!DOCTYPE html> {% load leaflet_tags %} <html lang=fr> <head> <title>{% block head_title %}titre{% endblock head_title %}</title> {% include 'snippets/css.html' %} {% leaflet_css %} {% leaflet_js %} </head> <body> {% include 'snippets/nav.html' %} <div class='container'> {% block content %} {% endblock content %} </div> {% include 'snippets/js.html' %} </body> </html> then my template : {% extends "base.html" %} {% block head_title %}{{ block.super }} | {{ object.nom }}{% endblock head_title %} {% block content %} <h1>{{ object.nom }}</h1> <table class="table table-sm"> <tr> <th>Catégorie</th> <td>{{ object.categorie }}</td> </tr> <tr> <th>Localisation</th> <td>{% leaflet_map "main" callback="map_init" %} <script … -
Django models/SQL How to determine the wanted "GROUP BY" part of the query?
I have a Django model ProjectName like this: class ProjectName(models.Model): name = models.CharField(_("name"), max_length=255) hasused = models.BooleanField() def __str__(self): return self.name class Meta: managed = False db_table = 'timeentry_project' It is a database view and my goal is to put the most recent projects to the top of the view and get rid of any duplicates in order to be able to provide the queryset to a ModelChoiceField as a parameter. That is also why ProjectName.objects.raw query does not solve the problem. ModelChoiceField does not accept a raw query set. That is also why I cannot use a set containing duplicates. The current situation is that I have the following queryset (Django queryset for that is OK) content: ID Name hasbeenused 81 Mossefixaus 1 80 Ladojen korjaus 0 81 Mossefixaus 0 82 Wartburg autojen koneremontit 0 The boolean value in a 'hasbeenused' column tells has the project been dealt with before or not. The used ones should be on the top of the list. The problem is that I cannot create a Django query that would produce the correct resultset that would be: ID Name max 81 Mossefixaus 1 80 Ladojen korjaus 0 82 Wartburg autojen koneremontit 0 The following … -
Comparing dates using a comparator inside Django template
I am trying to compare the end date of an event with today's date to see if the event has ended.

I have tried this in my html template: {% if event.end_date|date:"jS F Y H:i" <= today|date:"jS F Y H:i" %} {% include 'event/includes/enroll.html' %} But the button shows whether or not the event has ended already.

I added decorators too, to restrict the pages, but can' understand why is the error. viwes.py: @login_required def index(request): return render(request, 'dashboard.html') def loginPage(request): form = AuthenticationForm() if request.method == 'POST': username = request.POST.get('username') password = request.POST.get('password') user = authenticate(username=username, password=password) if user is not None: login(request, user) if request.GET.get('next'): return redirect(request.GET.get('next')) else: return redirect('feedback:index') return render(request, 'login.html', {'form': form}) urls.py app_name = 'feedback' urlpatterns = [ path('login/', views.loginPage, name="login"), path('logout/', views.logoutUser, name="logout"), path('', views.index, name="index"), ] the root urls.py: app_name = 'feedback' urlpatterns = [ path('admin/', admin.site.urls), path('', include('feedback.urls')), ] I also added these lines into my settings.py: LOGIN_URL = "login" LOGOUT_REDIRECT_URL = '/admin/' Anyone can see what I'm missing?
