How to load editorJs scripts integrated with django after an ajax call?
I am using editorJs for my description field as follows: epic_description = EditorJsField( editorjs_config={ "tools": { "Image": { "config": { "endpoints": { "byFile": "/imageUlaod/", "byUrl": "/imageUlaod/", }, "additionalRequestHeader": [ {"content-Type": "multipart/form-data"} ], } }, "Attaches": { "config": { "endpoint": "/fileUPload/", } }, } }, blank=True, null=True, ) But I also call this form of this field via ajax to load it. And it turns out that the script for the editorJs is not loaded at all. When I looked to my console it uses the cdn url https://cdn.jsdelivr.net/sm/jsdelivr-separator.js. Now I have no idea how to solve this issue since I do not know what script to load in the first place I check at the url to see if I can download the js file. Eiih nothing. Any help would be appreciated highly. -

Upgrade Django with incompatible migrations
I'm tasked with upgrading the Django version for a project that currently uses Django 2.2.24. It contains a model (with existing migrations) that looks roughly like this: class Membership(models.Model): person = models.ForeignKey(Person, on_delete=models.CASCADE) type = models.ForeignKey(MembershipType, on_delete=None) Starting with Django 3.0, on_delete=None causes an error since on_delete is supposed to be a callable. In order to avoid the error, both the model and the existing migrations have to be changed. By itself, it's not an issue to change the model like this: class Membership(models.Model): person = models.ForeignKey(Person, on_delete=models.CASCADE) type = models.ForeignKey(MembershipType, on_delete=models.SET_NULL, null=True) But existing databases are not yet aware that the corresponding field can be nullable, so a new migration is required for that. The best way I currently see to do this is the following: change the model create&apply a migration using Django 2.2.24 change the old migrations manually Is there a more elegant way to solve this issue? -
How can I test delete view in Django app?

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.

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?

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

I have problem showing discount result in input (created with django) The result of the multiplication does appear and using the same logic I implemented it for the descent point, however, although the code is very similar, it is not displayed I do not put all the django code because it seems that it is ok because it does read the result of the multiplication, it seems that it is more my logic error in javascript clicking on the button should give both results, which it does not do, it only shows one I add the image of the result function multiplicar(){ var quantity=parseInt(document.getElementById('id_quantity').value); var unit_price=parseInt(document.getElementById('id_unit_price').value); var percent=parseInt(document.getElementById('id_descuento').value); var total_price=document.getElementById('id_total_price'); var total=document.getElementById('id_total'); total_price.value=quantity*unit_price; console.log(total_price); total.value=(percent*total_price)/100; console.log(total); } <!-- Parts --> <h3>Partes</h3> <section> <div> <form> <div class="row"> <div class="col-12"> <div class="card"> <div class="card-body"> <h4 class="card-title">Partes</h4> <p class="card-title-desc">Agrega las partes que se incluirán</p> <div class="table-responsive"> <table class="table table-bordered table-nowrap align-middle" id="childTable1"> <thead class="table-info"> <tr> <th scope="col">Código</th> <th scope="col">Descripción</th> <th scope="col">Cantidad</th> <th scope="col">Precio Unitario</th> <th scope="col">Precio Total</th> <th scope="col">Libre de Impuestos</th> <th scope="col">Agrega Fila</th> </tr> </thead> <tbody> <tr> <td> {{presupuestosparteform.codigo}} </td> <td> {{presupuestosparteform.descripcion}} </td> <td> {{presupuestosparteform.quantity}} </td> <td> {{presupuestosparteform.unit_price}} </td> <td> {{presupuestosparteform.total_price}} </td> <td> <div class="form-check"> {{presupuestosparteform.tax_free}} </div> </td> <td> <input type="button" class="btn …
