Django rest framework nest two or more viewsets instead of mapping custom actions with @action decorator
So, lets pretend im trying to build an API for a tiny Chat application. Imagine i have 2 models in my Django project, one is for Messages and the other is for Groups. Each group can have multiple messages, but a message belows to only one Group (resulting in an one to many relationship). here are the models: class Group(models.Model): title = models.CharField(max_length=250) def get_messages(self): return self.messages.all() class Message(models.Model): body = models.TextField() group = models.ForeignKey(Group, on_delete=models.CASCADE, related_name="messages") And i have the following Django Rest Framework ViewSets: class GroupViewset(viewsets.ModelViewSet): queryset = Group.objects.all() serializer_class = GroupSerializer class MessageViewset(viewsets.ModelViewSet): queryset = Message.objects.all() serializer_class = MessageSerializer Viewsets are great! Only with those few lines i now have full CRUD operations for both Group and Message instances! I just need to access the following routes: /groups/ -> To make GET, POST operations for Group instances /groups/<group_pk>/ -> To make GET, PUT, PATCH, DELETE operations for Group instances /messages/ -> To make GET, POST operations for Message instances /messages/<message_pk>/ -> To make GET, PUT, PATCH, DELETE operations for Message instances but since a message belows to a Group, and i can get all messages of a group by doing GroupObject.get_messages(), im looking for a better way … -

Should data in in json file 'structured using li tags?
[ { "model": "db.service", "pk": 1, "fields": { "catagory_name": "New host", "service_name": "<ul><li>Trip planning</li><li>Host shop</li></ul>" } }, { "model": "db.service", "pk": 2, "fields": { "catagory_name": "TOURING HOSTS", "service_name": "Tour of location" } and it has another 5 written like the second activity. This is shown on the front end as a drop down of the activities (service_name). However the tech lead wants me to show trip planning as a bulleted activity, like this **- Trip Planning Host Shop** All as one selection. In the front end code, the previous intern has used regex to seek the li and ul tags and replace them with || for some reason. He wants me to get rod of those which is easy enough, but I was wondering if I should keep the code to seek the tags and somehow make them into bullet points. I have tried replacing the || with & but get &&, I then try replacing && with & but that doesn't work and there are still || in the code, so I tried replaceAll. However this still doesn't get me bullet points. Front end is react. I tried putting the code in brackets with li tags and that didn't … -

.distinct() ordering by date not only rows with group by, but group by as well?
Bid.objects.all() gives me two columns with date and bid_value. I want to have only one bid per date. Bid should be the highes value. So Bid.objects.all().order_by("date","bid_value").distinct("date") gives me proper order. But using last not only takes last row from QuerySet, but it takes last element from group_by made from distinct which i dont want. I would want only last element of queryset without any order changes. 1.Bid.objects.all() 2.Bid.objects.all().order_by("date","bid").distinct("date") 3.Bid.objects.all().order_by("date","bid").distinct("date").last() but it should give me 15.11.2022/50zł and actually list(Bid.objects.all().order_by("date","bid").distinct("date").last())[-1] gives me proper object 4.Bid.objects.all().order_by("date","bid").distinct("date").first() How i can still use .last() / .first() - without taking it into list. Because when i use list(Queryset), i have proper values on last objects. But changing queryset to list is not good standard i suppose. -
How to write a Django filter query for multiple values selected from a form without many if statements?
I have several Django forms of which when submitted I store the values like so if the forms are valid with only the min and max price being required, but the other values may be blank or not: max_budget = price_form.cleaned_data['max_price'] #required max_budget = price_form.cleaned_data['max_price'] #required another_value1 = other_form1.cleaned_data['another_value1'] #string another_value2 = other_form1.cleaned_data['another_value2'] #string another_value3 = other_form2.cleaned_data['another_value3'] #string another_value4 = other_form2.cleaned_data['another_value4'] #string another_value5 = other_form3.cleaned_data['another_value5'] #boolen value of 1 if selected another_value6 = other_form3.cleaned_data['another_value6'] #boolen value of 1 if selected I want to query a model (single database table) by using these variable values which correspond to specific fields in that DB as filters. The problem is that currently, I would have to use numerous carefully planned nested if/else statements each containing a variation of the line below to properly filter the DB based on the different possible values or lack thereof. query_results = Model.objects.filter(price__range=(min_budget, max_budget), field_in_the_DB="another_value1", field_in_the_DB="another_value2", field_in_the_DB__icontains="another_value3", field_in_the_DB__icontains="another_value4", field_in_the_DB="another_value5", field_in_the_DB="another_value6").order_by("Another_field_in_the_DB_not_related_these_values") This is because only the min and max prices are required to be entered so something like this would be required. price__range=(min_budget, max_budget) As for the other variables, some may have values or some may be left blank when submitted. Therefore, how can I filter the DB table … -

Unable to edit an object which has a foreign key in Django
I want to edit an object that has a foreign key in it. The problem that I am facing is that instead of editing the current object it is creating a new one.

Should I use Node.js or Django for my application?
I'm planing to build a cross-platform app as my first big project. I'm not yet familiar with any of the former frameworks, but I am looking forward to learning them. So far I am familiar with C, C++ and Python. The app will function as following: User uploads a photo, from which text is extracted and stored in associated file (I want to process images on front end, because I can't afford to process everything on the back end) Data is sent to the back end where it is stored With machine learning, data is being analyzed and organized into new groups (in the future I also want to add some AI to find answers to questions posed in the written text on the image) User can access reorganized groups, answers, his profile... So basically I want to do heavy processing on front end; organize everything, enhance data and store profiles/images on back end; implement a smart organization system; be able to access everything again on front end in a package as addictive as Instagram. I know I can easily implement OpenCV and make machine learning algorithms in Python, but I don't know how to make that on front end; … -

The problem is that it doesn't show me new notifications when they're being created and sent from the model's save method. consumers.py class NotificationConsumer(WebsocketConsumer): def get_notifications(self, user): new_followers = NotificationSerializer(Notification.objects.filter(content=1), many=True) notifs = { "new_followers": new_followers.data } return { "count": sum(len(notif) for notif in notifs.values()), "notifs": notifs } def connect(self): user = self.scope["user"] if user: self.channel_name = user.username self.room_group_name = 'notification_%s' % self.channel_name notification = self.get_notifications(self.scope["user"]) print("Notification", notification) self.accept() return self.send(text_data=json.dumps(notification)) self.disconnect(401) async def disconnect(self, close_code): await self.channel_layer.group_discard( self.room_group_name, self.channel_name ) async def receive(self, text_data): text_data_json = json.loads(text_data) count = text_data_json['count'] notification_type = text_data_json['notification_type'] notification = text_data_json['notification'] print(text_data_json) await self.channel_layer.group_send( self.room_group_name, { "type": "receive", "count": count, "notification_type": notification_type, "notification": notification } ) models.py class Notification(models.Model): content = models.CharField(max_length=200, choices=NOTIFICATION_CHOICES, default=1) additional_info = models.CharField(max_length=100, blank=True) seen = models.BooleanField(default=False) users_notified = models.ManyToManyField("core.User", blank=True) user_signaling = models.ForeignKey("core.User", on_delete=models.CASCADE, related_name="user_signaling") def save(self, *args, **kwargs): if self._state.adding: super(Notification, self).save(*args, **kwargs) else: notif = Notification.objects.filter(seen=False) data = { "type": "receive", "count": len(notif), "notification_type": self.content, … -

Django filter queryset
Django framework has a product model with about ten values that need to be filtered (color, type..). I'm trying to create a filter like this: views: ` class FilterCctvView(QuerySetsFromCctv, ListView): paginate_by = 32 def get_queryset(self): queryset = Cam.objects.filter( Q(maker__in = self.request.GET.getlist("maker")) | Q(type_of_cam__in = self.request.GET.getlist("type_of_cam")) ) return queryset in html: <form action="{% url 'filter' %}" method = 'GET'> <ul> <p><strong>Manufacturers</strong></p> {% for cam in view.get_cctv_makers %} <li> <input type="checkbox" class="checked" name="maker" value="{{cam.maker}}"> <span>{{cam.maker}}</span> </li> {% endfor %} </ul> <ul> <p><strong>Type of cameras</strong></p> {% for cam in view.get_cctv_type %} <li> <input type="checkbox" class="checked" name="type_of_cam" value="{{cam.type_of_cam}}"> <span>{{ cam.type_of_cam}}</span> </li> {% endfor %} </ul> <button class="btn btn-success btn-sm" type="submit">Find</button> </form> ` enter image description here But the filter doesn't work correctly!
