How to Save the current user for the created model object in django rest framework
Sorry if I'm asking a noob question. i have this model which used to create a article and the article has a field which associated to the django user model from django.db import models from django.contrib.auth.models import User class Article(models.Model): headline = models.CharField(max_length=150) body = models.TextField() author = models.ForeignKey(User, on_delete=models.CASCADE) pub_date = models.DateField(auto_now_add=True) pub_time = models.TimeField(auto_now_add=True) # fields need to be added # location # byline -> line tells who writes the article # conclusion # tags def __str__(self): return self.headline i use this django rest framework view to create the object. using postman and giving the author id i can create the article post @api_view(['POST']) def create(request): if request.method == 'POST': serializer = ArticleSerializer(data = request.data) if serializer.is_valid(): serializer.save() return Response(serializer.data, status=status.HTTP_201_CREATED) return Response(serializer.data, status=status.HTTP_400_BAD_REQUEST) what i need to achieve is the only the logged user need to be able to create the article and when the user create the article the author id need to be auto updated at the time the object was created. here is my serializer from rest_framework import serializers from . models import Article class ArticleSerializer(serializers.ModelSerializer): class Meta: model = Article fields = '__all__' -

I have a question about generic view in Django's tutorial example
In the “Writing your first Django app, part 4” of the tutorial of Django documentation, there is example of using generic view like blow ; File name : polls/views.py class IndexView(generic.ListView): template_name = "polls/index.html" context_object_name = "latest_question_list" def get_queryset(self): """Return the last five published questions.""" return Question.objects.order_by("-pub_date")[:5] class DetailView(generic.DetailView): model = Question template_name = "polls/detail.html" class ResultsView(generic.DetailView): model = Question template_name = "polls/results.html"` Q1 .in “class IndexView”, where is the “latest_question_list” defined? Is it the return value of “get_queryset” function? If so, how can I find the relationship between “latest_question_list”and “get_queryset” function? There is not any clue. Q2.there is a explanation in the tutorial like so: In previous parts of the tutorial, the templates have been provided with a context that contains the question and latest_question_list context variables. For DetailView the question variable is provided automatically – since we’re using a Django model (Question), Django is able to determine an appropriate name for the context variable. However, for ListView, the automatically generated context variable is question_list. To override this we provide the context_object_name attribute, specifying that we want to use latest_question_list instead. My question is that, it said the question variable is provided automatically for DetailVIew. what does the “question” … -

CS50W mail project, mark my read variable in my API as true as default but it must be false
I've been dealing with this bug for past few days and i can't fix it. So basically in this project i should make a email in a local host server using only JS, HTML and css. as you can see in the following code the read variable of the emails that get composed must remain false as default until you visit the email page : models.py : class Email(models.Model): user = models.ForeignKey("User", on_delete=models.CASCADE, related_name="emails") sender = models.ForeignKey("User", on_delete=models.PROTECT, related_name="emails_sent") recipients = models.ManyToManyField("User", related_name="emails_received") subject = models.CharField(max_length=255) body = models.TextField(blank=True) timestamp = models.DateTimeField(auto_now_add=True) read = models.BooleanField(default=False) archived = models.BooleanField(default=False) def serialize(self): return { "id": self.id, "sender": self.sender.email, "recipients": [user.email for user in self.recipients.all()], "subject": self.subject, "body": self.body, "timestamp": self.timestamp.strftime("%b %d %Y, %I:%M %p"), "read": self.read, "archived": self.archived } and it's not my JS file problem because i never even write anything for the read variable to change it : Inbox.js file : document.addEventListener('DOMContentLoaded', function() { // Use buttons to toggle between views document.querySelector('#inbox').addEventListener('click', () => load_mailbox('inbox')); document.querySelector('#sent').addEventListener('click', () => load_mailbox('sent')); document.querySelector('#archived').addEventListener('click', () => load_mailbox('archive')); document.querySelector('#compose').addEventListener('click', compose_email); document.querySelector('#submit').addEventListener('click', submit); // By default, load the inbox load_mailbox('inbox'); }); function compose_email() { // Show compose view and hide other views document.querySelector('#emails-view').style.display = 'none'; document.querySelector('#compose-view').style.display … -
Passing function from DjangoListAPI to a celery task

Deploying a complete full stack app to Railway
I have a full containerized frontend React app, I also have a full containerized backend Django/Python app (this simply works as an API) which accesses a Postgres database, and a third project which uses a Docker image of Postgres. I also have the full project using Docker Compose. What do you suggest that I do in order to deploy it to the Railway hosting: Deploy it to Railway using the complete Docker Compose project Deploy the React frontend, also deploy the Django/Python backend and also deploy the Postgres project Deploy just the frontend and backend, and use some sort of Postgres service that Railway could have I don't know which approach to take and which is viable. -
How can I exclude a subclass (or subclasses) of pages from Wagtail's search functionality?
I'm creating a blog site for a friend and there are certain page models that I would like to be excluded from users' searches. These models are BlogIndexPage and ThankYouPage. Both of these models subclass wagtail.models.Page. I want to have control over how these pages are visited and therefore don't want links for them to show up in search results if users search—for example—thank or blog. For context, this is the search view function: def search(request): search_query = request.GET.get("query", None) page = request.GET.get("page", 1) # Search if search_query: search_results = ( Page.objects.live().order_by("-first_published_at").search(search_query) ) query = Query.get(search_query) # Record hit query.add_hit() else: search_results = Page.objects.none() # etc... I've tried the two solutions suggested in this other thread and a third solution I found in the documentation, but they did not solve my problem. Specifically I tried the following: class ThankYouPage(Page): ... # Method One: @classmethod def get_indexed_objects(cls): return cls.objects.none() # Method Two: def get_indexed_instance(self): return None # Method Three: search_fields = [] I ran the update_index management command after each change. In the Django shell, I get the following behavior: >>> from wagtail.models import Page >>> from apps.contact.models import ThankYouPage >>> >>> Page.objects.all().search("thank") <SearchResults [<Page: Thank You Page>]> >>> >>> ThankYouPage.objects.all().search("thank") … -
How to define file path in a view method in django views.py
I need to read a CSV file in my view method. This is my view method in views.py in django project: def myfile(request): csv_fp = open('file.csv', 'r') reader = csv.DictReader(csv_fp) headers = [col for col in reader.fieldnames] out = [row for row in reader] return render(request, 'myfile.html', {'data' : out, 'headers' : headers}) This is in my urls.py: path('myfile/', views.myfile, name='myfile'), My django version is: 3.2.2 I tried many ways to open file in csv_fp = open('file.csv', 'r'). I used the below ways in my views.py and non of them worked: my file in the static directory: csv_fp = open('static/file.csv' , 'r') # not working csv_fp = open('file.csv' , 'r') # not working I added the below lines in my views.py and it didn't work as well: import csv, os from pathlib import Path BASE_DIR = Path(__file__).resolve().parent.parent STATIC_ROOT = os.path.join(BASE_DIR, 'static') file_path = os.path.join(STATIC_ROOT, 'file.csv') csv_fp = open(file_path , 'r') This is the error message: Exception Location: /home/djangoir/virtualenv/project/3.7/lib/python3.7/site-packages/django/template/loader.py, line 19, in get_template The point is I don't want to generate a model for the database and import CSV file into the database. I just need somehow read the file and export its data in a dictionary in the render method. -
Sending foreign key as argument resulting in This Field is Required Error
I am trying to create an app where Users can login and create tasks. The code for my django app is hosted here I am using JWT authentication and drf-yasg to generate swagger.

Correct way to store JSON into SQL database in React/Python(Django) app
So, I have, in my React application, a method that will generate a json with some settings and data, like this: const generateJSON = async () => { const json = generateManualJSON(caseId); const data = { cdata: customData, settings: json, }; try { const response = await Axios.post(`/manual/${caseId}/generate`, { manual_settings: JSON.stringify(data) }); console.log('response.data', response.data); } catch (error) { setError(arch, true, [error.message]); console.error(error); } }; and this will end up in this View in my Django application: class Manual(APIView): def transaction(self, case_id, action, request): user = request.user manual_settings = request.data['manual_settings'] if (action == 'generate'): CaseAutomationStatusModel.objects.create( current_ind=True, case_id=case_id, created_by=user, modified_by=user, status_comment=manual_wire_settings ) def post(self, request, case_id, action): try: self.transaction(case_id, action, request) return JsonResponse({ 'status': 200, 'message': 'Success' }) except Exception as err: print('*** API error', err) We are using PostgreSQL as database. The purpose of this is that we have a few jobs that run with nextflow and python running in paralel, and it this nextflow job will get this json in the database, and use it. But the problem is, the way it is currently stored, probably due to lack of escape characters, the database string input (which is the one we saved in the react/python project) is breaking up into … -
Chatbot with Knowledge base using GPT 3.5 turbo - Prompt optmizing [closed]
For context, I've been developing a chatbot with Chatgpt in pythom, more precisely, with Django. I am developing a prompt for my chatbot that uses chatgpt and it is giving some problems when I enter a lot of information in it. My goal for this prompt: What I want for my chatbot are short and objective answers, so that they can be as close as possible to a human, without leaving out some information. Problems encountered at the prompt: With my prompt, which I can provide, there are times when the chatbot is able to capture the menu data and there are times when it is not. Also, the chatbot generates some very large responses, passing unnecessary information to customers at that time of the response. The access link for my prompt is: "https://docs.google.com/document/d/1OGAlRGWQbhFbJWKKn5CBXobj3danvVskPsQuZa_CbTk/edit?usp=sharing" What has already been done: What I've been working on for a long time is a prompt for a chatbot that serves customers at a pizzeria. I'm trying to configure the prompt in countless ways but I'm not getting the ideal answers for my business. My prompt already has the menu separated in another context and is called, from the main prompt, through a function. With … -

I have: IntegrityError duplicate key value violates unique constraint "user_pkey" DETAIL: Key (id)=(3220037) already exists. This happens in this part of the code user = User() user.save() Model is pretty simple, 3 fields. So it happens when there are lot's of parallel requests to my endpoint. I thought Django deals with race condition under the hood in such an easy operation. Database is Postgres, default transaction isolation is read commited. Maybe smth changed with newer Django versions? Do I have to handle race condition by myself in code? -

Sync local postgres database with server postgres database?
Currently, I have a PostgreSQL database running on my local server, and everything is functioning well. Now, I want to synchronize this local database with another database on a remote server but only in a specific schema. There are two scenarios to consider: Case I: When an internet connection is available, I need the synchronization to occur immediately between the local and remote databases. Case II: In the absence of an internet connection, I want to store all changes in the local server. Once the internet connection becomes available, the system should automatically transfer all the unsynchronized data from the local server to the remote server. I need guidance on the best approach to achieve this synchronization considering both cases.
