Django REST Serializer not getting data from request
I have the following serializer setup to take in a postcode and return a list of service objects: class ServiceSearchSerializer(Serializer): area = CharField(max_length=16) services = DictField(child=JSONField(), read_only=True) def validate_area(self, value): if re.match('^[A-Z]{1,2}[0-9][A-Z0-9]? ?([0-9][A-Z]{2})?$', value) is None: raise ValidationError("This is not a valid postcode.") And I tried to use this to create an API endpoint which out take in the area. class ServiceSearchAPI(GenericAPIView): serializer_class = ServiceSearchSerializer def post(self, request, *args, **kwargs): serializer = self.get_serializer(data=request.data) if serializer.is_valid(raise_exception=True): area = serializer.data['area'] return Response(area) However, when trying to get the area from the serializer, it returns None. But the value for request.data['area'] is correct. Does anyone know why this is happening? -
Prevent Django from localizing numbers in templates
I have a Django template and am using localization by loading the packages and applying translate like this: {% load i18n %} {% load l10n %} .... {% translate "Menu" %} At some point I have a visual element where I provide the CSS width as a float variable from the view. Now when I change the language from en-us to de (German), the dot in the float is replaced with a comma and the value is not valid CSS anymore. This is the element: <div class="progress-header progress-el" style="width: {{p.max_width}}%"></div> I am aware of this question: How to prevent Django from localizing IDs in templates? And I have tried enclosing the relevant element in these tags: {% localize off %} <div class="progress-header progress-el" style="width: {{p.max_width}}%"></div> {% endlocalize %} As well as applying filters: <div class="progress-header progress-el" style="width: {{p.max_width|unlocalize}}%"></div> And: <div class="progress-header progress-el" style="width: {{p.max_width|safe}}%"></div> No success so far - any suggestions? -
Django - when 1 user accesses the same view with different url kwargs - why am I getting cross over of data?
I have a django app that contains samples. On my home page, it displays a table with many samples, containing hyperlinks to the 'Sample page' - which is a view get request. When I click on several of these samples in tandem, to open new tabs, each to a specific tab - I am getting cross over of data - I.e the url sample_id kwargs is different, but the page is displaying the same results which is incorrect. When i refresh the page, the correct sample data appears. Is there any way around this happening is a user is to open several different sample tabs at the same time? This would impact on results and could cause errors in the workflow offered by the django app. *is this because my view is processing too much, so the different view request=s ends up over lapping ? -

Django Custom Template Filter - How To Mention Users And Categories
I am making a social networking site, and I want to be able to mention users or categories by using the # symbol. (Example: #User #Category #Other Category). Using a template filter, I want to first find all the # in the string, and then get the word after it. Then I would check in the models for categories: class Category(models.Model): name = models.CharField(max_length=250, unique=True) category_detail = models.TextField(max_length=1250, default='No information is known on this category.') created_date = models.DateTimeField(default=timezone.now) follow_count = models.IntegerField(default=0) followers = models.ManyToManyField(User, related_name='followers') And if it does not match a category I would check if the word after the # is a user. If It is a category, I want to link it using the <a> tag, and if it is a user I also want to link it using the <a> tag. The urls: urlpatterns = [ path('u/@<str:username>', UserPostListView.as_view(), name='user-posts'), # User Profile Link. Link This If After The # The Word Is A User path('c/<str:cats>/', views.category_view, name='category-detail'), # View Category Link.

How to add M2M data directly to form in Django
I have a form field which gets added through a Mixin. This field is not saved in the database. Instead, I need to take this field and convert it to a field in the form that will be saved in the database. The field in the database is named receiver: receiver = models.ManyToManyField(EmployeeType, related_name='policies_receiver') Instead of the user selecting the receivers, I would like them to use this new form field which has been added to the form via Mixin: class SelectEmployeeTypeFormMixin(forms.Form): """ Adds a "select_employee_type" radio field to a form. If checked, the appropriate employee types/roles will be applied to the object. """ CHOICES = ( ('this_department', 'Employees in my department.'), ('company_wide', 'All employees in this company.'), ) select_employee_type = forms.ChoiceField( widget=forms.RadioSelect(), choices=CHOICES, initial='this_department', label='Who is this for?' ) The select_employee_type form value needs to be converted to the receiver field in the view. I have done this by saving the form then updating the receiver in the form as such: updated_request = request.POST.copy() if policies_form.is_valid(): if request.user.role.supervisor is None or request.user is policies_form.sender: policies_form.save() if updated_request['select_employee_type'] == 'this_department': subs_id = request.user.subordinates.values_list('role', flat=True) sub_roles = EmployeeType.objects.filter(Q(pk__in=subs_id) | Q(pk=request.user.role.id)) policies_form.instance.receiver.set(sub_roles) policies_form.save() The problem I am having is that I use … -

(Angular + Django REST) Suppress Browser Auth Dialog?
I use JWT Authentication for my Angular + Django REST project. Recently the browser keeps showing the Basic auth dialog whenever the token expires. I know by removing/changing the WWW-Authenticate header can suppress the dialog but I could not get it to work. On Django, I have tried to use a custom Response object to force the response header: def BaseResponse(data, status=None, template_name=None, headers=None, content_type=None): response = Response(data, status, template_name, {'WWW-Authenticate': 'xBasic'}, content_type=None) response['WWW-Authenticate'] = 'xBasic' return response Also I have tried to use a middleware: AuthHeaderMiddleware.py class AuthHeaderMiddleware(object): def __init__(self, get_response): self.get_response = get_response def __call__(self, request): return self.get_response(request) def process_response(self, request, response): if response.status == 401: r = Response(response.data, response.status, response.template_name, {'WWW-Authenticate': 'xBasic'}, response.content_type) return response Middleware settings in settings.py: MIDDLEWARE = [ 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', 'corsheaders.middleware.CorsMiddleware', 'middleware.AuthHeaderMiddleware', ] The problem is the WWW-Authenticate header remains Basic for all 401 responses (but 'xBasic' for other statuses). I use the djangorestframework-simplejwt package in Django. On Angular, I have tried to force a blank token with the Bearer declaration for the Authorization header: add_header(request, token=null) { var r = request.clone({ setHeaders: { 'Content-Type': 'application/json', 'Authorization': `Bearer ${request.withCredentials ? token : ''}` } }); return r; } … -
Count & Sum of Order Values for each customer (through iteration) in Django

How to filter data in the backend for displaying geotags via GeoJSONLayerView to the Map
I need to display weather stations only in the areas(filter by id_ugms) of the country that the user chooses. But the geodjango tools do not allow you to filter the data in the backend. GeoJSONLayerView extracts all the data from the table, and I have to filter the entire list in leaflet on the frontend. There are a lot of records in the table, which is why the response time is very long(it takes more than 5 minutes to display and filter), or it crashes from the server altogether. How do I do backend filtering? Maybe there's another way? I tried just to make a selection, and serialize the data via geojsonserializer - nothing worked, leaflet does not give an error of input data. Technology stack: Postgis, Django, Leaflet. There is a model of my entity: models.py class WeatherStation(gismodels.Model): id_station = models.IntegerField(primary_key=True) station_index = models.IntegerField(default = None) name_station_rus = models.CharField(default="", max_length=256) name_station_en = models.CharField(default="", max_length=256) id_ugms = models.ForeignKey(Ugms, on_delete=models.CASCADE, default = None) id_country = models.ForeignKey(Country, on_delete=models.CASCADE, default = None) id_subrf = models.ForeignKey(Subrf, on_delete=models.CASCADE, default = None) latitude = models.CharField(default ="", max_length=256) longitude = models.CharField(default ="", max_length=256) geom = gismodels.PointField(default ='POINT EMPTY',srid = 4326) objects = gismodels.Manager() height_above_sea = models.CharField(default="", max_length=256) … -

I'm trying by doing the following in the table definition <tbody> {% for datarow in dataset %} <tr> <td>{{datarow.supplierName}}</td> <td>{{datarow.invoiceNumber}}</td> <td>{{datarow.reference}}</td> <td><a href = "open(r'\\REMOTESERVER\Shared1\FOLDER\FOLDER Images\{{datarow.docId|urlize}}\file.tiff')">Open Invoice</a> {% endfor %} </tr> </tbody> however it doesn't open as the url still tries to map from localhost. Also in each folder I have one .tiff file but other files as well, I'm also looking into having a way to open that .tiff file (different name per folder) to be used in the url but I haven't got there yet.
