OrgChart in Django and JQuery
I have an app that I created in Django and OrgChart jQuery that displays an organizational workchart. I have UserProfile model that I create every time when user is created so it updates automatically. Right now, I am working on a script that would allow me to add 2 people to the same position and level of hierarchy.

Axios error when using catch for error processing
I'm using React + Django. Simple backend with one button on frontend handling POST requests: function handleSubmit(e){ e.preventDefault(); axios.post(API_URL, { forklift, battery }).then((response) => { console.log(response) }).catch((error) => { console.log(error.response) }); } The problem is when I try to submit the form while including .catch it always throws an 404 error on first request and then my development server on django crashes on second request (stops). When I delete catching error it works perfectly. function handleSubmit(e){ e.preventDefault(); axios.post(API_URL, { forklift, battery }).then((response) => { console.log(response) }); } My Django API_VIEW @api_view(['POST']) def start_charging(request): if request.method == 'POST': print('test') forklift_ean = request.data['forklift'] battery_ean = request.data['battery'] try: forklift = Forklift.objects.get(for_ean=forklift_ean) battery = Battery.objects.get(bat_ean=battery_ean) except Forklift.DoesNotExist or Battery.DoesNotExist: return Response({'error_message': "No object error"}, status=status.HTTP_404_NOT_FOUND) return Response({"message": "OK"}) Main url.py file urlpatterns = [ path('admin/', admin.site.urls), path('api/', include('my_app.urls')) ] App url.py file urlpatterns = [ path('charging/', views.start_charging, name='start_charging'), ] Error on first request: xhr.js:220 POST http://127.0.0.1:8000/api/charging/ 404 (Not Found) Error on seconds request (server crashes): xhr.js:220 POST http://127.0.0.1:8000/api/charging/ net::ERR_CONNECTION_REFUSED Any idea why might be the reason for .catch to act that way? -

Error when working with qs, does not take a field in the query
I have a queryset with data. I want to add an annotate for it with data from another qs. To do this, I filter by pk and by FK field, I take in_stock values in this field, but I get error: Related Field got invalid lookup: in_stock.

Django Admin: How to use the button to move to the selected URL?
I am very new to Django and trying to make my first project. I find it difficult to use the buttons I created to move to the selected URL. Let's say my app is called TestForms and my models are: Patients, General, PST and ERBT. I would like to create two buttons - 'Previous' and 'Next' - which will be used to go to previous/next forms respectively. I try to do so using admin templates in django. NOTE: I know changing built-in templates are not a very good idea, I will create new html file to extend this templates before doing changes on the server. For now I am doing it locally on my computer. In submit_line.html I created two new buttons and they are like so: {% if show_save_and_go_to_next_form %}<input type="submit" value="{% translate 'Next' %}" class="default" name="_gotonextform">{% endif %} {% if show_save_and_go_to_previous_form %}<input type="submit" value="{% translate 'Previous' %}" class="default" name="_gotopreviousform">{% endif %} This gives me two good-looking buttons on the site. But these are just saving the results (working like 'Save' button), but not redirecting me to the next form as I would like to. When I am adding a new patient (admin/TestForms/patient/add/), after clicking on 'Next' I would … -

I have no error message, because Django automatically uses LocMem as cache instead of Redis. This is my settings.py file.

How and where to call post_migrate where Django's own Permission model is the sender
In my current project I want to use Django Group model objects as access roles. I'm trying to programmatically assign permissions to the group instances that should have them (for example, 'delete_something' for 'moderator', and Permission.objects.all() for 'admin'), but even though the code runs without errors, no permissions are assigned. After reading a few similar questions, I have a guess that it must be connected to either the order of migrations or some specifics of Permissions migration. Currently, my code runs from the AppConfig class of one of my project's apps that contains most of the models, and is called by its ready() function. I wonder if that is the right place to call that code. I also think that it would make sense for Permission model to be the signal sender, but I don't understand at what point I should be able to call it (when it is registered/ready) and from which part of my project? I attach my current apps.py code below. from django.apps import AppConfig from django.db.models.signals import post_migrate class ReviewsConfig(AppConfig): name = 'reviews' verbose_name = name.capitalize() def setup_permissions(self, sender, **kwargs) -> None: """Get and set permissions for the groups that should have them.""" from django.contrib.contenttypes.models import …
