Django js tabs keep selected tab on page refresh
I'm working with js tabs (https://www.w3schools.com/howto/howto_js_tabs.asp) in Django and they work fine but I'd like to keep the selected tab active on that moment on page refresh. Is there an easy way to do it? I found similar questions but they are not valid for my case... This is the script I'm using: function openTab(evt, tabName) { var i, tabcontent, tablinks; tabcontent = document.getElementsByClassName("tabcontent"); for (i = 0; i < tabcontent.length; i++) { tabcontent[i].style.display = "none"; } tablinks = document.getElementsByClassName("tablinks"); for (i = 0; i < tablinks.length; i++) { tablinks[i].className = tablinks[i].className.replace(" active", ""); } document.getElementById(tabName).style.display = "block"; evt.currentTarget.className += " active"; } -

Exposing simple types on WSDL with Spyne
We are trying to build a SOAP app with Django + Spyne building specific required endpoints. The exposed WSDL has to precisely match a predetermined XML file, including the custom simpleType definitions. We're currently failing to show the simple type definitions on our WSDL, everything else matches up precisely. A simple example is the following hello world app: import logging logging.basicConfig(level=logging.DEBUG) from spyne import Application, rpc, ServiceBase, \ Integer, Unicode, SimpleModel from spyne import Iterable from spyne.protocol.xml import XmlDocument from spyne.protocol.soap import Soap11 from spyne.interface.wsdl import Wsdl11 from spyne.server.django import DjangoApplication from django.views.decorators.csrf import csrf_exempt class IdType(SimpleModel): __type_name__ = "IdType" __namespace__ = 'spyne.examples.hello' __extends__ = Unicode class Attributes(Unicode.Attributes): out_type = 'TxnIdType' class HelloWorldService(ServiceBase): @rpc(IdType, Integer, _returns=Iterable(Unicode)) def say_hello(ctx, TxnIdType, times): for i in range(times): yield 'Hello, %s' % TxnIdType application = Application([HelloWorldService], tns='spyne.examples.hello', interface = Wsdl11(), in_protocol=Soap11(validator = 'lxml'), # out_protocol=XmlDocument(validator='schema') out_protocol=Soap11() ) hello_app = csrf_exempt(DjangoApplication(application)) Which yields the following WSDL: <wsdl:definitions xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:plink="http://schemas.xmlsoap.org/ws/2003/05/partner-link/" xmlns:wsdlsoap11="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:wsdlsoap12="http://schemas.xmlsoap.org/wsdl/soap12/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:soap11enc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:soap11env="http://schemas.xmlsoap.org/soap/envelope/" xmlns:soap12env="http://www.w3.org/2003/05/soap-envelope" xmlns:soap12enc="http://www.w3.org/2003/05/soap-encoding" xmlns:wsa="http://schemas.xmlsoap.org/ws/2003/03/addressing" xmlns:xop="http://www.w3.org/2004/08/xop/include" xmlns:http="http://schemas.xmlsoap.org/wsdl/http/" xmlns:tns="spyne.examples.hello/types" xmlns:s0="spyne.examples.hello" targetNamespace="spyne.examples.hello/types" name="Application"> <wsdl:types> <xs:schema targetNamespace="spyne.examples.hello/types" elementFormDefault="qualified"> <xs:import namespace="spyne.examples.hello" /> <xs:complexType name="say_helloResponse"> <xs:sequence> <xs:element name="say_helloResult" type="xs:string" minOccurs="0" nillable="true" /> </xs:sequence> </xs:complexType> <xs:complexType name="say_hello"> <xs:sequence> <xs:element name="IdType" type="s0:IdType" minOccurs="0" nillable="true" /> <xs:element name="times" type="xs:integer" minOccurs="0" … -
Django - Pathing Issue (I think!)
I've created a restuarant booking system using Django. Trying to achieve full Crud functionality. Just trying to sort out the update and delete. So basically when i open the user account it comes up with the reservations they've made and the option to edit or Delete them. Where my issue is is when i have my url paths as follows: urlpatterns = [ path('', views.ReservationsFormView.as_view(), name='reservations'), path('edit/<slug:pk>/', EditReservationView.as_view(), name="edit_reservation"), path('view/<slug:pk>/', ReservationCompleteView.as_view(), name="reservation_complete"), path('reservations_account/', ReservationAccountView.as_view(), name="reservations_account"), path('delete/<slug:pk>/', DeleteReservationView.as_view(), name="delete_reservation"), ] It won't load the account screen as it says: error screen 1 and when I change my paths to as follows: urlpatterns = [ path('', views.ReservationsFormView.as_view(), name='reservations'), path('edit_reservation', EditReservationView.as_view(), name="edit_reservation"), path('view_reservation/', ReservationCompleteView.as_view(), name="reservation_complete"), path('reservations_account/', ReservationAccountView.as_view(), name="reservations_account"), path('delete_reservation/', DeleteReservationView.as_view(), name="delete_reservation"), ] It does load the account screen but when i hit the Edit or Delete button i get the following: error screen 2 Relatively new to Django so any help is grealy appreciated.

How can I migrate my existent sqlite db to postgres on heroku?

How can I pass in the login/register data for my django-rest api in the form of a url?
I am following along with a book on the django-rest framework and I am having issues grasping a certain concept. The book uses the built-in Browsable API feature to do basic CRUD and LOGIN/LOGOUT/REGISTRATION functionality. What it fails to mention is how I can achieve such functionality using only the URL, which would be needed for, say connecting the API to the frontend of a REACT app. Example: I have an API which displays Posts and this path shows all posts: path('api/v1/', include('posts.urls')), I want to use this path for example, to register. path('dj-rest-auth/registration/', include('dj_rest_auth.registration.urls')), How would the URL look like ? -

Can't figure out DeclarativeMeta error with alembic and sqlalchemy in django project

Using Alembic and sqlalchemy instead of Django ORM (relatively new to all the above) and successfully made a migration and migrated it to alembic version folder. Whole reason I'm using alembic sql alchemy is because I am trying to hit external api and was told in another post that alembic was needed to manage migration histories or there would be issues with django tracking migrations.
