How to use javascript to remove a property defined by django?
I am trying to make password fields required only if a checkbox is checked. Initially, the check box is checked so the fields are defined required in Django: forms.py class SampleForm(forms.ModelForm): check = forms.BooleanField(required=False) password1 = forms.CharField(widget=forms.PasswordInput) password2 = forms.CharField(widget=forms.PasswordInput) class Meta: model=MyModel def __init__(self, *args, **kwargs): super(SampleForm,self).__init__(*args, **kwargs) self.fields['check'].widget.attrs.update({'onclick':"hidePass()",'id':"check"}) self.fields['password1'].widget.attrs.update({'id':"password1"}) self.fields['password2'].widget.attrs.update({'id':"password2"}) I tried the following: <script> function hidePass() { var checkBox = document.getElementById("check"); var password1 = document.getElementById("password1"); var password2 = document.getElementById("password2"); if (checkBox.checked == true){ password1.disabled = false; password1.required = true; password2.disabled = false; password2.required = true; } else { password1.disabled = true; password1.required = false; password2.disabled = true; password2.required = false; } } </script> but it didn't work. It could disable the fields but they were still required. I tried to replace password1.required = false; by: password1.removeAttribute("required"); bu I got the same result. -
Django - Celery send task to remote rabbitmq broker
I want to separate my celery server from the Django server. I tried to install rabbitmq and celery on a different server and tried to send tasks from my django server.I am not receiving any tasks into the remote celery server.

Django: Problems collecting static files
I have: STATIC_URL = "/statics/" STATIC_ROOT = os.path.join(BASE_DIR, "static") And I have another app that has a static folder, so I collect static files from all the apps with python manage.py collectstatic, this creates a folder named statics with admin, frontend, rest_framework folders. Each of these are the apps, but right now I need the frontend. Inside the frontend folder, there's a main.js file which is the react js app. So I have a frontend app, inside the templates I have my frontend folder and inside the folder I have index.html <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Document</title> </head> <body> <div id="app"></div> {% load static %} <script src="{% static 'frontend/main.js'%}"></script> </body> </html> But the problem is that I get 404 not found, what could be the problem?? The URL for the main.js file as I can see is - http://192.168.0.52:8000/statics/frontend/main.js Although in the HTML you can see {% static 'frontend/main.js'%}, I used this before to collect the file inside the app, but now I have used collectstatic, so I have the main statics folder and should I get the files from it? or what? -
Getting django signals to work between applications
I have a Django app called receipt_printer which should be printing an order when it is received using a signal. There are two apps here called: Orders and receipt_printer. However, whenever an order is processed and fully charged I can't get the signals to work. The example below just prints out something to the console for simplicity. If I do everything inside the models.py in the Orders app it works fine. receipt_printer/apps.py from django.apps import AppConfig class ReceiptPrinterConfig(AppConfig): name = 'receipt_printer' def ready(self): from . import signals receipt_printer/signals.py from django.db import models from saleor.order.models import Order from django.db.models.signals import post_save def order_fully_paid_signal(sender, instance, created, **kwargs): if instance.get_payment_status() == "fully-charged": print("This signal is working for fully paid order") else: print("This signal won't working for fully paid order") post_save.connect(order_fully_paid_signal, sender=Order) receipt_printer/init.py default_app_config = 'receipt_printer.apps.ReceiptPrinterConfig' -

How to use both Django Auth and DRF Token auth?

Django Connecting To Quickbooks Online Via Backend
I'm trying to push data into Quickbooks online from my backend django app but Oauth is pretty tough for me to understand. I'm attempting to use requests-oauth and the backend application workflow. https://requests-oauthlib.readthedocs.io/en/latest/oauth2_workflow.html#backend-application-flow I am able to generate a token but i'm getting a 401 back when I try to use it. I can't tell whether the code that is being returned is bad because the code that I generate via the QBO developer playground also does not work for my request. The request does work in the developer playground. Can anyone show me an example of connecting to quickbooks via a backend workflow.
