Django Rest Framework serializer returning nested records that should be filtered out on update
I override my FormSerializer's update method. It marks some nested field records as is_deprecated if necessary. However, the Api call returns all records, even though my get_queryset filters out everything is_deprecated. As far as I can tell, the get_queryset is being called to get the instance, which is then passed to the serializer. This instance does not contain any previously deprecated records. After the update method completes, it looks like another query must be run that gets ALL of these nested records and serializes them. This only occurs on updates. I get the correct records on a standard GET request. Any idea where this second query is being called and how to override it? Alternatively, I guess I could edit the serialized data in to_representation, but I'd like to understand what is going on here first. View class FormViewSet(LoginRequiredMixin, viewsets.ModelViewSet): serializer_class = FormSerializer queryset = Form.objects.all() def get_queryset(self): if 'pk' in self.kwargs: qs = Form.objects.filter(id=self.kwargs['pk']) else: qs = Form.objects.filter(id__in=name_dict.values()).order_by('name') queryset = FormSerializer.eager_loading(qs) return queryset Serializer class FormSerializer(serializers.ModelSerializer): id = serializers.IntegerField(required=False, allow_null=True) fields = FieldSerializer(many=True) class Meta: model = Form fields = '__all__' @staticmethod def eager_loading(queryset): return queryset.prefetch_related(Prefetch('fields',queryset=Field.objects.filter(is_deprecated=False).order_by('field_order'))) -
I added ajax to my voting buttons and it is working but it is not updating number of votes without refreshing
I would like to ask you for your help. I use Django and I built my voting system and added ajax to it to avoid refreshing my page after clicking "UP" or "DOWN". And it is working (it updates my buttons without actually refreshing page). But my votes numbers are also included in the same part of code but they are not updating alongside buttons. To view change in number of votes i actually need to refresh whole site (f5). Could someone please explain to me why is that and what can I do about it ? My voting section: Vote Up: {{ total_voteup }} Vote Down: {{ total_votedown }} {% if is_voteup %} <form method='POST' action="{% url 'voteup' %}"> {% csrf_token %} <button type='submit' id="voteup" name="question_id" value="{{ question.id }}">Revert /\</button> </form> {% elif is_votedown %} <form method='POST' action="{% url 'votedown' %}"> {% csrf_token %} <button type='submit' id="votedown" name="question_id" value="{{ question.id }}">Revert \/</button> </form> {% else %} <form method='POST' action="{% url 'voteup' %}"> {% csrf_token %} <button type='submit' id="voteup" name="question_id" value="{{ question.id }}">/\</button> </form> <form method='POST' action="{% url 'votedown' %}"> {% csrf_token %} <button type='submit' id="votedown" name="question_id" value="{{ question.id }}">\/</button> </form> {% endif %} My js scripts: <script type="text/javascript"> $(document).ready(function(event){ … -
Django Page Error 404 - Loading JSON via uri
Hi I am working on a React Frontend - Django rest framework, serving API as backend. When I am loading a model it returns this error 404. I am not sure how I can include the /models in the urls.py so that I am able to load the .json files. Can i use Media_URL or static_URL to serve json files ? Page not found (404) Request Method: GET Request URL: http://localhost:8000/models/movies.json Using the URLconf defined in movieproject.urls, Django tried these URL patterns, in this order: ^api/movies/$ [name='movies-list'] ^api/movies\.(?P<format>[a-z0-9]+)/?$ [name='movies-list'] ^api/movies/(?P<pk>[^/.]+)/$ [name='movies-detail'] ^api/movies/(?P<pk>[^/.]+)\.(?P<format>[a-z0-9]+)/?$ [name='movies-detail'] ^$ [name='api-root'] ^\.(?P<format>[a-z0-9]+)/?$ [name='api-root'] The current path, models/movies.json, didn't match any of these. You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page. -

How can I exclude rest-auth endpoint from the Django built-in API documentation?
To hide the endpoint in the Django documentation just @schema(None) has to be added for example to GenericAPIView, however I have a problem with these three urls: url(r'^swagger/', schema_view), url(r'^rest-auth/', include('rest_auth.urls')), url(r'^rest-auth/registration/', include('rest_auth.registration.urls')), I am not able to add @schema(None) decorator because I do not have declared views for these urls. Any ideas how to work it around? -

I am trying to write a python test that involves testing if the environment variables provided are valid. I am passing the environment variables as follows env = EnvironmentVarGuard() env.set('GOOGLE_CREDENTIALS', GOOGLE_CREDENTIALS) The GOOGLE_CREDENTIALS is an import from a python file. the GOOGLE_CREDENTIALS works while in a .env but once I do the import from a file I receive the following error self.__credentials = ServiceAccountCredentials.from_json_keyfile_dict( File "/Users/esir/CFA/DebunkBot/venv/lib/python3.8/site-packages/oauth2client/service_account.py", line 251, in from_json_keyfile_dict return cls._from_parsed_json_keyfile(keyfile_dict, scopes, File "/Users/esir/CFA/DebunkBot/venv/lib/python3.8/site-packages/oauth2client/service_account.py", line 185, in _from_parsed_json_keyfile signer = crypt.Signer.from_string(private_key_pkcs8_pem) File "/Users/esir/CFA/DebunkBot/venv/lib/python3.8/site-packages/oauth2client/_pure_python_crypt.py", line 167, in from_string marker_id, key_bytes = pem.readPemBlocksFromFile( File "/Users/esir/CFA/DebunkBot/venv/lib/python3.8/site-packages/pyasn1_modules/pem.py", line 44, in readPemBlocksFromFile substrate = ''.encode().join([base64.b64decode(x.encode()) for x in certLines]) File "/Users/esir/CFA/DebunkBot/venv/lib/python3.8/site-packages/pyasn1_modules/pem.py", line 44, in <listcomp> substrate = ''.encode().join([base64.b64decode(x.encode()) for x in certLines]) File "/Users/esir/.pyenv/versions/3.8.0/lib/python3.8/base64.py", line 87, in b64decode return binascii.a2b_base64(s) binascii.Error: Incorrect padding the part using the env variable is ServiceAccountCredentials.from_json_keyfile_dict(json.loads(os.getenv('GOOGLE_CREDENTIALS'), strict=False), scopes=self.__scope) so my question is why does it work if I just set the GOOGLE_CREDENTIALS on the .env file buf fails if I try using EnvironmentVarGuard -

Setting the Format for the Django DatetimeInput Widget
I would like to use the included Django DateTimeInput widget as a datetimepicker on my website. No matter what I try however, the widget returns a datetime value in an incorrect format which will not send to my database. I need the format '%Y-%m-%d %H:%M:%S', but the widget returns '%d/%m/%Y %H:%M:%S' This problem has been discussed a tad here: http://stackoverflow.com/a/35968816/1382297 I believe the problem may be from setting the input_type to DateTime-local, but I don't know other options and cannot find any in the documentation. I've tried passing format='%Y-%m-%d %H:%M:%S' to the widget, as well as FORMAT_INPUTS = ['%Y-%m-%d %H:%M:%S'], and tried initializing these in the DateInput class, all with no luck. Here is my forms.py class DateTimeInput(forms.DateTimeInput): input_type = 'datetime-local' class EnterMatchForm(forms.ModelForm): class Meta: model = match fields = ('match_name', 'player1', 'player2', 'victory', 'match_description', 'match_date') widgets = { 'match_date': DateTimeInput(), } What is the right way to set up the widget so that it returns datetime values in the format Y-m-d H:M:S?

For the further enhancement study, can anyone get me some examples to update the wagtail page in the right way? sorry for my English. class RestaurantPage(Page) .... #other attribute view_count = models.PositiveIntegerField(default=0, editable=False) @property def restaurant_page(self): return self.get_parent().specific def get_context(self, request, *args, **kwargs): context = super(RestaurantPage, self).get_context(request, *args, **kwargs) context['restaurant_page'] = self.restaurant_page context['restaurant'] = self self.tracking(request) return context def tracking(self, request): track = TrackUserRest() if request.user.is_authenticated: track.user_id = request.user.id else: track.user_id = 0 track.restaurant_id = self.pk track.time = timezone.now() track.save() self.view_count = self.view_count+1 return super(RestaurantPage, self).save() #version 1 class TrackUserRest(models.Model): user_id = models.ForeignKey(ExtendedUser, on_delete=models.CASCADE) restaurant_id = models.ForeignKey(RestaurantPage, on_delete=models.CASCADE) time = models.DateTimeField(auto_now=True, auto_now_add=False) class Meta: ordering = ('time', ) def __str__(self): return 'Restaurant Tracking system: usee.id({}) viewed rest.id({}) at timezone.({})'.format(self.user, self.rest.title, self.time) #version 2 class TrackUserRest(models.Model): user_id = models.PositiveIntegerField(null=True) restaurant_id = models.PositiveIntegerField(blank=False, null=False) time = models.DateTimeField(auto_now=True, auto_now_add=False) class Meta: ordering = ('time', ) def __str__(self): return … -
django-allauth Not Saving Social Info and social token etc
I have a customer profile assisiated with user so I wanted to make a customer profile on first login so I made a adopter for this like this class MyAccountAdapter(DefaultSocialAccountAdapter): def pre_social_login(self, request, sociallogin): user = sociallogin.user if user.id: return try: user = User.objects.get(email=user.email) # if user exists, connect the account to the existing account and login sociallogin.state['process'] = 'connect' perform_login(request, user, 'none') raise ImmediateHttpResponse(redirect(settings.LOGIN_REDIRECT_URL.format(id=request.user.id))) except Exception as e: incominguser = User.objects.filter(email=user.email).first() if not incominguser: user.username=user.email user.save() newCustomer = Customer() newCustomer.customerProfile = user newCustomer.save() perform_login(request, user, 'none') raise ImmediateHttpResponse(redirect(settings.LOGIN_REDIRECT_URL.format(id=request.user.id))) else: raise ImmediateHttpResponse(redirect(settings.LOGIN_REDIRECT_URL.format(id=request.user.id))) ISSUE by doing this tables like Social application tokens are not being generated or nor Social accounts are being created . -
Use django variables passed as context in script tag of HTML file
I am stuck using <script> tags to render a googlemaps api window in my django webapp. In my views I passed my data as such: def map_view(request): context = { 'title': 'My Map', 'machines': Machine.objects.all(), } return render(request, 'gui/map_view.html', context) But can't figure out how to use machines in the javascript code.

How to use django-autocomplete-light on form with multiple charfields
I have installed django-autocomplete-light. My form without autocomplete looks like this: class FilterForm(forms.Form): form_origin = forms.CharField(label='From country', max_length=100, required=False, widget=forms.TextInput(attrs={ 'placeholder': 'From country', 'arial-label':'C2', })) form_target = forms.CharField(label='To country', max_length=100, required=False, widget=forms.TextInput(attrs={ 'placeholder': 'To country', 'arial-label': 'C1', })) I have written a view following the instructions here, which gives all the countries which start with the same letter as my input. class CountryAutocomplete(autocomplete.Select2QuerySetView): def get_queryset(self): qs = Country.objects.all() qs = qs.filter(name__istartswith=self.q) return qs However, I am having issues with using it with the form, which has two char fields, both to use the same model called Country. The tutorial isn't tailored to that. In essence, I hope to have two text boxes, with autocomplete of the country to and from, a bit like skyscanner. Any advice to the right direction is appreciated! My model looks like this: class Country(models.Model): iso3 = models.CharField('3 Digit ISO', max_length=3, unique=True) name = models.CharField('Name', max_length=50) lon = models.FloatField() lat = models.FloatField() def __str__(self): return self.name -
