How do I filter a model in html django
I'm trying to filter a model in HTML I know that you can use eg. Model.objects.filter(bla=bloo, ...). I wanna do that in HTML not in my views.py. my model looks like this: class Like(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE, related_name="likeUser") post = models.ForeignKey(NewPost, on_delete=models.CASCADE) heres my views.py: posts = NewPost.objects.all() like = Like return render(request, "network/index.html", { "posts": posts, "like": like )} heres what I'm trying to do in HTML: {% for post in posts %} {{ like.objects.filter(post=post) }} {% endfor %} I'm getting an error right now saying: Could not parse the remainder: '(post=post)' from 'like.objects.filter(post=post)' How can I make it work? -

Django Pagination & Filters appending to url rather than replacing
I have a Django page that has a table to display the data from my model. This table has pagination as well as multiple filters. I have manage to get the pagination and filters to work together to an extent, however the URL is all messed up. It looks like it is appending the new query string to the end of the URL. I have two main issues with this: If I use a single filter, it adds all the empty query strings in the URL for all filters. If I have filtered data in the table and try to change the page, It append the page query string on the end rather than replace it. Screenshot for issue 1: Screenshot for issue 2: filters.py: class SetFilter(django_filters.FilterSet): name = CharFilter(field_name='name', lookup_expr='icontains', label='', ) type = AllValuesFilter(field_name='type', choices=Set.objects.values_list('type', flat=True).distinct().order_by('type'), label='', empty_label="") nonfoil = AllValuesFilter(field_name='is_non_foil_only', choices=Set.objects.values_list('is_non_foil_only', flat=True).distinct().order_by('is_non_foil_only'), label='', empty_label="") foil = AllValuesFilter(field_name='is_foil_only', choices=Set.objects.values_list('is_foil_only', flat=True).distinct().order_by('is_foil_only'), label='', empty_label="") digital = AllValuesFilter(field_name='is_online_only', choices=Set.objects.values_list('is_online_only', flat=True).distinct().order_by('is_online_only'), label='', empty_label="") foreign = AllValuesFilter(field_name='is_foreign_only', choices=Set.objects.values_list('is_foreign_only', flat=True).distinct().order_by('is_foreign_only'), label='', empty_label="") class Meta: model = Set fields = '' views.py def sets_page(request): set_list = Set.objects.order_by('-id') last_modified = set_list[0].last_modified set_filter = SetFilter(request.GET, queryset=set_list) set_list = set_filter.qs paginator = Paginator(set_list, 22) is_paginated = True if … -

Django: The model has two identical many-to-many relations through the intermediate model
I have seen this question: The model has two many-to-many relations through the intermediate model But I think my problem is slightly different: class Building(models.Model): name = models.CharField(max_length=64) prices = models.ManyToManyField('Resource', through='BuildingResourceRelation', related_name="prices") outputs = models.ManyToManyField('Resource', through='BuildingResourceRelation', related_name="outputs") inputs = models.ManyToManyField('Resource', through='BuildingResourceRelation', related_name="inputs") class Resource(models.Model): name = models.CharField(max_length=64) class BuildingResourceRelation(models.Model): building = models.ForeignKey('Building', on_delete=models.CASCADE) resource = models.ForeignKey('Resource', on_delete=models.CASCADE) amount = models.PositiveIntegerField() According to design there can be a different amount of prices, inputs, and outputs. I can create through model for each, but isn't there a better way? -

Djoser change email language
Is there a way to change the email that is sent in djoser based on the language of the user instance? I have found this question How do I explicitly specify language of email I want to send?, but it does not seem to be an option in the last version of djoser, since there are no longer views for each action (activation, reset password etc.) or I have not figured out how it works. Also, I have tried inhereting the UserViewSet class and apply the translation, but I do not know if this is the way to do it and how to specify all the urls of djoser. class UserViewSet(djoser_view.UserViewSet): def perform_create(self, serializer): user = serializer.save() signals.user_registered.send( sender=self.__class__, user=user, request=self.request ) context = {"user": user} to = [get_user_email(user)] language = user.language or 'en-us' with translation.override(language): if settings.SEND_ACTIVATION_EMAIL: settings.EMAIL.activation(self.request, context).send(to) elif settings.SEND_CONFIRMATION_EMAIL: settings.EMAIL.confirmation(self.request, context).send(to) def perform_update(self, serializer): super().perform_update(serializer) user = serializer.instance language = user.language or 'en-us' with translation.override(language): if settings.SEND_ACTIVATION_EMAIL: context = {"user": user} to = [get_user_email(user)] settings.EMAIL.activation(self.request, context).send(to) @action(["post"], detail=False) def activation(self, request, *args, **kwargs): serializer = self.get_serializer(data=request.data) serializer.is_valid(raise_exception=True) user = serializer.user user.is_active = True user.save() signals.user_activated.send( sender=self.__class__, user=user, request=self.request ) language = user.language or 'en-us' with translation.override(language): if … -
Which Class is calling the Serializer Class in Django REST
I have two APIView classes and one ModelSerializer class. The APIView classes are using the serializer class. Is there any way to know which APIView class is calling the serializer class? I need seperate representation_view for these 2 APIView. APIView Classes class OwnerAllListAPIView(APIView): def get(self, request, *args, **kwargs): user = self.request.user all_list = ListName.objects.filter(owner=user).all() list_serializer = core_slr.ListNameSerializer(all_list, many=True) return response('Owner list', list_serializer.data, status.HTTP_200_OK) class ListNameDetailAPIView(APIView): def get(self, request, *args, **kwargs): list_name = ListName.objects.filter(id=self.kwargs.get('list_name_id')).first() list_serializer = core_slr.ListNameSerializer(list_name) return response('list name detail view', list_serializer.data, status.HTTP_200_OK) Serializer Class class ListNameSerializer(serializers.ModelSerializer): class Meta: model = ListName fields = [ 'id', 'owner', 'name' ] def to_representation(self, instance): ret = super(ListNameSerializer, self).to_representation(instance) ret['owner'] = f"{instance.owner.first_name} {instance.owner.last_name}" ret['total_question'] = QuestionBank.objects.filter(list_name=instance).count() return ret In the to_representation View, I just wanna to know which API is currently calling the serializer. -
Why I cannot retrieve the session_data while I can get the session_key in Django session
So I was trying to get a anonymous user to login, and then get the session key/data pair that include his name and pw so that it can be send back to an outside app. Later, going to other views, the user can keep being logged in. But I cant seem to be able to get the data from the session. I just get the session_key, but not the session_data in below sessiondata=request.session.session_data. It seems to be empty.

How to add extra field in model serializer?
I am very new to django rest framework. I have two models ModelA and ModelB. I have a ModelB searilzer to display all the fields in get request. Because of some reasons ModelA and ModelB are not related by FK but ModelA.objects.get(modelB.field1=modelA.pk) this will return single data. class ModelASerailzer(serializers.ModelSerializer): class Meta: model = ModelA fields = ['f1','f2'] class ModelBSerailzer(serializers.ModelSerializer): # I want to do something like this here new_field = ModelA.objects.get(modelB.field1=modelA.pk).f1 # this will return the data in shell #and normal django view but I don't know how to implement this in django rest ? class Meta: model = ModelB fields = ['field1','field2', 'new_field'] -
Django - use redirect view with multiple parameters
Im trying to redirect to a view with multiple parameters: in my urls.py (app exhibition) I have: path('map/<float:lat>/<float:lng>/<int:zoom>', views.MapView.as_view(), name='map') where float is defined in a path converter like this: '[-+]?\d*\.?\d*' For the redirection I have: return redirect('exhibition:map', lat=48.128365,long=11.5662713,zoom=3) After hours of trying and researching similar questions I still get: Reverse for 'map' with keyword arguments '{'lat': 48.128365, 'long': 11.5662713, 'zoom': 3}' not found. 1 pattern(s) tried: ['de/map\\/(?P<lat>[-+]?\\d*\\.?\\d*)\\/(?P<lng>[-+]?\\d*\\.?\\d*)\\/(?P<zoom>[0-9]+)$'] If I adjust the url pattern and the redirect call to a single pattern (be it float or int) the redirection works. Thus the problem should be related to my usage of multiple parameters - but I just can see what is wrong. Any hints welcome!
