Create custom button in django template from jquery append() method
After the fetch of data returned by an API, I append data into django template, and I also create a button which contains already the url of the detail page specified in urls.py. The detail page has this url: http://127.0.0.0:8000/blog/<int:user_id>/<int:year>/<int:month>/<int:article_id>, so for example: http://127.0.0.0:8000/blog/1/2022/8/1 I'm trying to add a django url in this way (jquery): for(var i=0; i < data.articles.length; i++){ var item = $('<p>Titolo: '+data.articles[i].title+'<br>Autore: '+data.articles[i].author +'<br>Data: '+data.articles[i].pub_date+'</p><a id="button_' + data.articles[i].id + '"><button class="btn btn-primary">Dettaglio</button></a>'); $('#article_list').append(item); $("#button_" + data.articles[i].id).attr('href', "{% url 'blog:detail' "+ data.path_info.user_id +" "+ data.path_info.year +" "+ data.path_info.month +" "+ data.articles[i].id +"%}"); } Analyzing the html page I see: <a id="button_1" href="{% url 'blog:detail' 1 2022 8 1%}"><button class="btn btn-primary">Dettaglio</button></a>, which is correct When I click the button, Django returns this error: The current path, blog/1/2022/{% url 'blog:detail' 1 2022 8 1%}, didn’t match any of these. http://127.0.0.1:8000/blog/1/2022/%7B%25%20url%20'blog:detail'%201%202022%208%201%25%7D N.B.: data.path_info contains correct info about the path tags to use. How can I do to reach the correct path specifying it into jquery? -
PyJWT Token Cannot Be Decoded [closed]
I'm converting a deviceid to a JWT Token while a user is registering via their deviceid. Then I'm using the same JWTtoken in URL request's header but Django just throws an error jwt.exceptions.DecodeError: Invalid header string: 'utf-8' codec can't decode byte 0xeb in position 1: invalid continuation byte even though I just created the JWTtoken using it. I checked online and some people recommended converting to UTF-8 but not sure if that would work or how to do it.

How do I access django join table data?
I'm trying to access data in a join table using django. I have a list of users and a list of groups in a ManyToMany relationship. class Member(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) groups = models.ManyToManyField(Group, related_name="members") class Team(models.Model): name = models.CharField(max_length=25) creator = models.ForeignKey("footballteamapi.Member", on_delete=models.CASCADE) The join table looks like this: footballteamapi_member_teams id+member_id+team_id 1+1+1 2+1+2 3+2+1 How do I go about accessing that table since there's no coinciding model to reference (i.e. Team.objects.all())? -
Django ModelForm ManyToManyField with Blank=True, Required=False '"" is not a valid value for a primary key' error
I have a Django model for creating an Asset object with an optional m2m field for managers: class Asset(models.Model): name = models.CharField(max_length=100) managers = models.ManyToManyField("users.User", blank=True, related_name="assets") And a custom ModelForm: class AssetForm(forms.ModelForm): managers = forms.ModelMultipleChoiceField(queryset=User.objects.none(), required=False) class Meta: model = Asset fields = [ "id", "name", "managers" ] def save(self, commit=True): instance = super().save(commit) def __init__(self, *args, **kwargs): super(AssetForm, self).__init__(*args, **kwargs) self.fields["managers"].queryset = self.org.get_users_with_management_access_role() def clean(self): cleaned_data = super(AssetForm, self).clean() return cleaned_data With a view to submit the form with: try: if request.method == "POST": if 'asset_id' in request.POST: asset = Asset.objects.get(id=request.POST['asset_id']) asset_form = AssetForm(request.POST, instance=asset) else: asset_form = AssetForm(request.POST) try: if asset_form.is_valid(): asset_form.save() asset_form.save_m2m() else: raise ValueError("form_errors") except: raise ValueError("form_errors") return JsonResponse({"message": "Asset successfully created"}, status=200) I have: Blank=True set on the m2m model field Required=False set on the ModelForm field for managers Calling asset_form.save_m2m() in the view Yet if I leave the field blank and submit the form, it still returns "" is not a valid value for a primary key.

Error Refactoring the views into a single ViewSet
I am completing my first course RESTful Routes on TDD. Now I am on Part 1 Restful Routes and we are asked to refactor the views into a single ViewSet. I have been following the tutorial provided Django REST Framework Views - ViewSets and i've combined my APIView's to a ViewSet in my views.py file: from django.shortcuts import get_object_or_404 from rest_framework.response import Response from rest_framework.viewsets import ViewSet class MovieViewSet(ViewSet): movies = Movie.objects.all() def list(self, request): serializer = ItemSerializer(self.queryset, many=True) return Response(serializer.data) def retrieve(self, request, pk=None): item = get_object_or_404(self.queryset, pk=pk) serializer = ItemSerializer(item) return Response(serializer.data) I am struggling with handling the URLs. # urls.py from django.urls import path, include from rest_framework import routers from .views import MovieViewSet router = routers.DefaultRouter() router.register("api/movies/", MovieViewSet) urlpatterns = [ path("api/movies/", MovieViewSet), path('', include(router.urls)), ] Here, we created a router (using DefaultRouter, so we get the default API view) and registered the ItemsViewSet to it. When creating a router, you must provide two arguments: The URL prefix for the views The ViewSet itself Then, we included the router inside urlpatterns. As per these instructions I thought I needed to recreate the url that we had in the APIView i.e http://localhost:8009/api/movies/ but I get the following error. … -
bootstrap 5 - d-flex class changing checkbox width
I have a list of products where there are 3 elements in each row: checkbox, label, and number of components related to this product. I want ot have all elements in 1 row. I have a problem with checkbox width because d-flex is changing the width of the checkbox if the product title is too long. It looks like this: I tried to use the grid system but it moves my span element to the next line when the text is too long.

How to write a Graphene+Django filter that acts upon two columns at the same time
I am trying to write a filter in Graphene + Django that takes a single input but acts upon two columns at the same time. The two columns represent two numbers a and b, and the filter I want is one that select all element where the product of a and b is greater that some filter value. class MyModel(models.Model): a = models.FloatField() b = models.FloatField() class MultiplicationFilter(Filter): def filter(self, qs, value): # what to do here??? class MyModelCustomFilter(FilterSet): class Meta: model = MyModel multiplication_filter = MultiplicationFilter(field_name=???) # I can't have 2 fields, what do I put here? order_by = OrderingFilter( fields=("a", 'b'), ) class MyModelNode(DjangoObjectType): class Meta: model = MyModel fields = "__all__" filterset_class = MyModelCustomFilter interfaces = (graphene.relay.Node, ) I am aware that Django offers so more elaborate querying functionality by means of a Q() function, but I don't know how to formulate this in the Graphene Filter type of way.
