How can I test delete view in Django app?
I want to test my View but I have problem with my delete function. class AnimalView(APIView): def delete(self, request, format = None): id = int(request.GET.get('id')) try: animal = Animal.objects.get(id=id) except: return Response(status=status.HTTP_404_NOT_FOUND) animal.delete() return Response(status=status.HTTP_204_NO_CONTENT) This is my model: class Animal(models.Model): name = models.CharField(unique=True, max_length=30, blank=False, null=False) class Meta: managed = True db_table = 'animal' ordering = ['name'] def __str__(self): return str(self.name) and this is the test that I'm trying to make: class TestURL(TestCase): def setUp(self): self.client = Client() def test_animal_delete(self): animal = Animal.objects.create(name = 'TestAnimal') response = self.client.delete(reverse("category_animal"), json.dumps({'id' : animal.id})) self.assertEqual(status.HTTP_204_NO_CONTENT,response.status_code ) But I'm getting a TypeError: int() argument must be a string, a bytes-like object or a number, not 'NoneType' Can you please help me with my test? -
Use template date filters in custom template tag?
I want to use Django template date filters inside a custom template tag. Is that possible? My end goal is to be able to use it like this: {{parcel.pickup_dates|delivery_dates_formating}} Problem is, that "pickup_dates" can be array of 1 or 2 or 3 elements. My desired output is: "Sunday, 21 September" if one element, "Satardau - Sunday, 21-22 September" if 2 elements, "Friday - Sunday, 20-22 September" if 3 elements, Currenly my temlpate tag looks like this: def delivery_dates_formating(value): if len(value) == 1: return [value[0]] if len(value) == 2: return [value[0], value[1]] if len(value) == 3: return [value[0], value[2]] And in template I used to use something like: {{parcel.delivery_date|date:'E j, l'|capfirst}} I woul like to use django tempaltes date filtes, as it handels localisation. Is that possible? -
Where do Django's Field's "default" and test's "client" parameters come from?
If you search for the parameters of a Field (e.g. IntergField) in Django through from django.db import models dir(models.IntegerField) you get 'default_error_messages', 'default_validators', 'unique', 'validate', 'validators', etc, but not "default" itself, although it's commonly used, as in class Choice(models.Model): ... votes = models.IntegerField(default=0) Same thing with "client". The docs say TestCase "comes with its own client". In this snippet from Django's docs, this client is explored class QuestionIndexViewTests(TestCase): def test_no_questions(self): """ If no questions exist, an appropriate message is displayed. """ response = self.client.get(reverse('polls:index')) but you can't find it through from django.test import TestCase dir(django.test.TestCase) or even dir(django.test.TestCase.client_class) I'm asking where they come from, but also how to search for these "hidden" parameters, methods, etc. -
Django call SOAP API
I made a CRM and now the company wants to set up their API, but it's a SOAP API who uses XML and after a little research here in Stack, some people said to use zeep, and didn't work. I'm trying first from a separate file to put in the CRM later (maybe not the best idea) but I think I'm doing wrong/more than I need to. Is it right to do this way or is there a better way ? from zeep import Client client = Client('httsp://company.com/?wsdl') element1 = client.get_element('ns0:E1') element2 = client.get_element('ns1:E2') element3 = client.get_element('ns2:E3') element4 = client.get_element('ns3:E4') element5 = client.get_element('ns4:E5') element6 = client.get_element('ns5:E6') element7 = client.get_element('ns6:E7') element8 = client.get_element('ns7:E8') element9 = client.get_element('ns8:E9') obj1 = element1(E1 = 'A') obj2 = element2(E2 = 'B') ... obj9 = element9(E9 = 'I') header_value = header(username='user', password='pass') client.service.Companymethod(_soapheader={heaeder_value, obj1, obj2, ... obj9}) XML: <definitions targetNamespace="http://X/soap/X"> <types> <xsd:schema targetNamespace="http://X/soap/X"> <xsd:import namespace="http://schemas.xmlsoap.org/soap/encoding/"/> <xsd:import namespace="http://schemas.xmlsoap.org/wsdl/"/> <xsd:complexType name="Companymethod"> <xsd:all> <xsd:element name="YRequest" type="tns:YRequest" minOccurs="1"/> </xsd:all> </xsd:complexType> <xsd:complexType name="YRequest"> <xsd:all> <xsd:element name="E1" type="xsd:string" minOccurs="1" maxOccurs="1"/> <xsd:element name="E2" type="xsd:nonNegativeInteger" minOccurs="1" maxOccurs="1"/> <xsd:element name="E3" type="xsd:string" minOccurs="1" maxOccurs="1"/> <xsd:element name="E4" type="xsd:string" minOccurs="1" maxOccurs="1"/> <xsd:element name="E5" type="xsd:nonNegativeInteger" minOccurs="1" maxOccurs="1"/> <xsd:element name="E6" type="xsd:boolean" minOccurs="0" maxOccurs="1"/> <xsd:element name="E7" type="xsd:nonNegativeInteger" minOccurs="0" maxOccurs="1"/> <xsd:element name="E8" type="xsd:nonNegativeInteger" … -

Django implicit field naming for class with query expression - how does it work?
Simplified example of what I wrote today: class Grandparent(models.Model): text = models.CharField(max_length=5, choices=too_many) class Parent(models.Model): grandparent = models.ForeignKey(Grandparent, on_delete=models.CASCADE) info = models.CharField(max_length=30) class ChildSomething(models.Model): parent = models.ForeignKey(Parent, on_delete=models.CASCADE) data = models.CharField(max_length=5, choices=chromosome_identities) Given a specific Grandparent object, I wanted to order Parent objects underneath it by most ChildSomething's each Parent has, which I did successfully below. grandparent = Grandparent.objects.get(id=32923) # arbitrary id # This query produces the desired result parents = ( Parent.objects.filter(grandparent=grandparent). annotate(num_child_somethings = Count('childsomething')). order_by('num_child_somethings') ) My question: Why is it Count('childsomething') instead of Count('child_something')? The latter was my intuition, which was corrected by a helpful Django error message: Exception Type: FieldError Exception Value: Cannot resolve keyword 'user_translation' into field. Choices are: id, translate_text, translate_text_id, translation, usertranslation The answer to this is likely simple, I just couldn't find anything in the docs related to this. How does the naming convention work? If anyone knows of the appropriate Django docs link that would be ideal. Thank you. -
Django Webpack static not finding file
I created a Django application and tried to serve files via webpack. Now the application can't find those files despite setting the required constants in settings.py. The output folder is right in the root directory and should be picked up by STATICFILES_DIRS, but if I start the application I get a 404 not found error.

Field data disappears in Django REST framework
I have a field "plugins" (see below) in my serializer and this is a serializer which also contains a file upload which is why the MultiPartParser is used. My view is pretty much standard, and the plugins field data also shows up in the request.data, however it doesn't show up in the validated_data of the serializer. To bring a minimalistic example, this would be my serializer: class CreationSerializer(serializers.ModelSerializer, FileUploadSerializer): plugins = serializers.ListSerializer( child=serializers.CharField(), required=False, write_only=True) class Meta: fields = ['plugins'] + FileUploadSerializer.Meta.fields model = Company def create(self, validated_data): print(validated_data) While this would be my views.py: @swagger_auto_schema(request_body=CreationSerializer(), responses={201: CreationSerializer()}, operation_id='the_post') def create(self, request, *args, **kwargs): print(request.data) return super().create(request, *args, **kwargs) # which uses mixins.CreateModelMixin -
Cleaner django filters in graphql query
I have a project in angular where we use graphql to gather data from api that is created in django. I am using filters that are available in django-filter and here is my question. My example query looks like this: query foo( ... $something_Icontains: String, $something_Iexact: String, $something_IstartWith: String, $something_IendsWith: String, $something_IsNull: String, ... ) { foo( ... something_Icontains: $something_Icontains, something_Iexact: $something_Iexact, something_IstartWith: $something_IstartWith, something_IendsWith: $something_IendsWith, something_IsNull: $something_IsNull, ... ) { result { ...fooFields } } } It is quite lengthy and grows exponentially when more fields is added. Is there any way to shorten it? -

Should i use Vue or django for URL routing?
I have been learning web development for two months, in tutorials there is a video about path and components with vue. const routes= [{ path:"/", component: () => import(./views/home) }] As far as i know you can do the same thing with django as well. urlpatterns = [path('', views.special_case_2003),] Which one should i use for URL routing? If they are doing same thing then why should i use a backend framework? -

Custom Permissions Verification Django Rest Framework
I am trying to figure out the best way to write a custom permission in Django Rest Framework for the following use case. I have a User model and a Organization model. A User can have multiple Organizations and an Organization can have multiple Users. I have this model to connect the relationships: class UserOrganization(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) organization = models.ForeignKey(Organization, on_delete=models.CASCADE) role = models.CharField(max_length=255, default="Owner") primary_org = models.BooleanField(default=False) Users are able to create integrations to third party services, but these are tied to both the User and the Organization. I currently have the following custom permission that checks the User but how do I check if they are a member of the Organization? class UserPermission(permissions.BasePermission): def has_object_permission(self, request, view, obj): # Deny actions on objects if the user is not authenticated if not request.user.is_authenticated(): return False if view.action == 'retrieve': return obj.user == request.user or request.user.is_admin elif view.action in ['update', 'partial_update']: return obj.user == request.user or request.user.is_admin elif view.action == 'destroy': return request.user.is_admin else: return False The Organization id will be passed with every API call.

Django-rules replacement of guardian.mixins.PermissionListMixin

¿why the discount is not seen in the template with javascript?

In Django, how do I access and display the full name of a user in an Admin filter, when the full name is a foreign key value?
I am using the default Django admin and User model. I'm trying to add a field to list_filter where the field's value is username. But I would like to display the user first_name and last_name in the filter. I'm not sure how to access those user values from the admin. Here's a little code that doesn't work: list_filter = ('status', 'assignee_full_name') @property def assignee_full_name(self, obj): return obj.assignee.first_name + obj.assignee_last_name (assignee is the field I'm sorting on, that's the one with the value that equals the username.) This code as written doesn't work. The error message is <class 'intake.admin.ClientAdmin'>: (admin.E116) The value of 'list_filter[1]' refers to 'assignee_first_name', which does not refer to a Field. What do I need to do differently to get assignee.first_name and assignee_last_name into a form that will be recognized or displayed by list_filter? There's a similar question at Django Display User as user Full Name in Admin Field, in fact this code was derived from that answer, but the accepted answer is unsatisfactory; as it says right in the answer, it "doesn't work". I appreciate that the questions are substantially similar, but the answer provided does not answer the question. -
How do I change an environment variable only during tests in Django?
I have a class that extends the root TestCase. I would like to set an environment variable in each of the tests that extend this class so that I don't cycles on unnecessary API queries. When I place the patch decorator outside of the class, it appears to have no effect. When I place the patch decorator just above the setUp, the patch appears to only last through the duration of the setUp. import mock, os from django.test import TestCase #patching here seems to have no effect class TCommerceTestCase(TestCase): @mock.patch.dict(os.environ, { "INSIDE_TEST": "True" }) def setUp(self): self.assertEqual(os.environ["INSIDE_TEST"], "True") # works! def test_inside_test(self): self.assertEqual(os.environ["INSIDE_TEST"], "True") # Fails! How do I patch an environment variable in a Django test (without manually patching to every function?) -
Bokeh & Django: RuntimeError("Models must be owned by only a single document")

Django stops serving static css files; but static images keep working
Template: {% load static %} <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8" name="viewport" content="width = device-width, initial-scale = 1"> <link rel="stylesheet" href="{% static "css/custom/nav.css" %}"> <link rel="stylesheet" href="{% static "css/custom/fonts.css" %}"> </head> <body> <div> <figure> <img src="{% static 'icons/logo.png' %}" alt=""> </figure> </div> </body> settings: BASE_DIR = Path(__file__).resolve().parent.parent STATIC_URL = '/static/' STATICFILES_DIRS = [ BASE_DIR / "webapp/static", ] STATIC_ROOT = "django_static" Problem: Django doesn't load static files. The browser throws: [Error] Failed to load resource: the server responded with a status of 404 (Not Found) (nav.css, line 0) Not found: http://127.0.0.1:8000/static/css/custom/nav.css But, the images in static files work quite well. The URL for the main logo gets rendered to: http://127.0.0.1:8000/static/icons/logo.png Pictures get served without a problem, css doesn't. This happened in my opinion random. I had this issue formerly on a different page where css for the admin page apparently just stopped working and I couldn't figure out why. Now it happened for all css files on a bigger project that I can't just scrap and restart. I have no idea why this happens or how to troubleshoot this. I changed all static paths around, did collectstatic several times, added static paths to urls.py... Nothing changed. Edit: as I don't … -
