Making a post request to a Django app on MS Azure from a client that I do not own getting cors error
I have deployed a django app on azure and have been running it for a while. I recently added an endpoint to my app that should get a POST request from the jengahq website. However, I am able to simulate post requests from them to my endpoint and see the responses. Everytime I simulate my POST request, I get an error: Access to fetch at https://notification-webservice.azurewebsites.net/... from origin jengahq site has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource... However, I have enabled cors-origin for this website. It also requires a basic authentication header which I have added appropriately as shown below: CSRF_TRUSTED_ORIGINS = ( ["https://" + os.environ["WEBSITE_HOSTNAME"], "https://secondsite", ]) CORS_ALLOWED_ORIGINS = [ "https://" + os.environ["WEBSITE_HOSTNAME"], "https://secondsite", ] CORS_ALLOWED_HEADERS = [ 'Accept', 'Accept-Encoding', 'Authorization', ... ] The first website in my cors allowed is where my frontend is served and I am able to run requests well. This does not work for the second website. When I remove my frontend site from my cors allowed list, I get a similar error, but the endpoint seems different: Access to fetch at mysite from origin myfrontend has been blocked by CORS policy... Even with the addition … -
Can't send a labNumber into an sql query
I'm very confused as to why my _labNumber variable isn't getting sent into the method that I am using to call an SQL query, as it works for other methods in the same class. I have a try catch block in my class that calls the methods where I pass in _labNumber(This is correctly assigned, I have triple checked it) try: _comment = self.dataServices.GetComment(_labNumber) _value2 = self.dataServices.GetValue2(_labNumber) _value1 = self.dataServices.GetValue1(_labNumber) _results = self.dataServices.getResults(_labNumber) except AttributeError: _comment = None _value2 = None _value1 = None _results = None This is one of the methods in the class that is being used to retrieve the data from the database: def GetValue2(self, _LabNumber): _LabNumberStr = str(_LabNumber) try: with connection.cursor() as _cursor: _cursor.execute("{CALL dbo.uspShireXGetValue2(%s)}", _LabNumberStr) row = _cursor.fetchone() if row: return {'VALUE2': row[0]}#21 else: return {'VALUE2': None} except Exception as e: # Handle or log the exception as appropriate print(f"An error occurred: {e}") return {'VALUE2': None} And finally here is the query that I know works as it returns the data when I hard code a lab number: @LabNumber VARCHAR(10) AS SET NOCOUNT ON SELECT WDR.COMMENT FROM dbo.DNA_WORKSHEET_DET WD INNER JOIN dbo.DNA_WORKSHEET W ON WD.WORKSHEET = W.WORKSHEET LEFT OUTER JOIN dbo.DNA_TEST T ON W.TEST … -
127.0.0.1 slowness in django virtual environment running with vscode
After connecting to the server built in awsec2 with a remote of vscode, the django virtual environment was run to make a connection of 127.0.0.1. But its speed is too slow. When you connect using Chrome, the loading is too slow, sometimes it's infinitely loaded, and sometimes there's content that hasn't been loaded even if it's marked. There are even cases where only white pages are displayed. I'm currently using a MAC. Using a Windows laptop, connecting remotely to a remote server using vcode and then connecting to 127.0.0.1 will work fine I've been looking for other posts, but none of them correspond to my issues. I've tried many things. Turn off the process that currently uses 8000 ports on the Mac (but it was not there) Connect django to 8888 port or unused port and view it (this is the same error as well) It used to work very well, but it doesn't work well at some point. What should I do? -

How to design my Django app database to accommodate multiple level information of an item?
I am trying to create an app on Django. Struggling on how to proceed on Database schema. There are the following tables: 1), table customer: cust_name cust_addr cust_phone created_date ... 2), table customer_assets customer (foreign key pointed to table customer) asset_type asset asset_update_time asset_creation_time ... The major issue is on asset, asset_type, sample data like below: asset_type asset domain aaa.bb.example.com domain *.corp.example.com ip 10.1.2.3 ip 10.8.0.0/16 url http://aaaa url http://bbbbb url http://aaa.bb.example.com/app1/login email xxx@example.com there are some assets like *.corp.example.com, 10.8.0.0/16. The app is supposed to do a discovery and find more assets under them, for example: aaa.corp.example.com bbb.corp.example.com ccc.corp.example.com 10.8.2.2 10.8.2.3 ... The app is then going to scan the open ports on each of them, like: aaa.corp.example.com. (22, 80, 1080) 10.8.2.2 (21, 139, 3306) the app may then scan every ports on the assets to find urls, like: aaa.corp.example.com 80 /home.html aaa.corp.example.com 80 /admin.html bbb.corp.example.com 443 /console Note that: data in customer_assets is basically provided by customer data in customer_assets contains data of various types, for example, 1), wildcard sub domains (.corp.example.com) and exact subdomains (aaa.bb.example.com). 2), exact subdomains in wildcard sub domains (.corp.example.com) will later be discovered what's the best way to organise the database schema? 1), … -
Warrning from unittest on models.DateTimeField with auto_now=True
I got model in Django 4.2.1 that has an autofield updated each time anytching is changed in record. Implemented only by this one line: last_modification = models.DateTimeField(auto_now=True, editable=True) In PGAdmin I see correct created records. And in standard usage I got no warnings inside container terminal. But whent I run tests by command inside container "python manage.py test" I recieve warnings like: warnings.warn( /usr/local/lib/python3.11/site-packages/django/db/models/fields/init.py:1595: RuntimeWarning: DateTimeField SMSNotification.last_modification received a naive datetime (2024-02-02 13:46:49.356514) while time zone support is active./bin/sh: 3: Syntax error: newline unexpected (expecting ")") warnings.warn( /usr/local/lib/python3.11/site-packages/django/db/models/fields/init.py:1595: RuntimeWarning: DateTimeField SMSNotification.last_modification received a naive datetime (2024-02-02 13:46:49.356514) while time zone support is active. Is this a common unittest problem or my implementation of model? If should be ignored, can I configure test framework to avoid printing the warning? -
Trying to lay out a variable number of cards per row with Django and Bootstrap
I have a variable number of items on Bootstrap cards that I will be laying out (maybe 100). I want to lay this out to put as many per row as will fit (let's assume fixed width). On a larger screen, I should get | 1 2 3 4 | On a smaller one: | 1 2 | | 3 4 | I'm looping through the item with a for loop in a Django template. Every method I've found assumes that the server will have a preset number of columns in the row. This makes no sense to me, as I want to set the with for readability (like 20em), and then put as many items per row that fit. This is what I have, it doesn't work. <div class="container-fluid"> <div class="row"> {% for person in people %} <div class="row"> <div class="card width=25%"> <img class="teacher-pic card-img-top" style="float:left; margin: 0 15px 0 0;" src="{{ person.person_photo_url }}"/> <div class="card-body"> <h5 class="card-title">{{ person.person_name }}</h5> <p class="card-text">{{ person.person_description }}</p> </div> </div> </div> {% endfor %} </div> </div> -

Triggering Python Function on Django + React
I am attempting to send data from my React frontend to a Django backend and trigger a function. I'm developing a Django REST API using Django Rest Framework, and I've set up a view in the calculator app to handle POST requests. The objective of the calculator view is simply concatenate text from frontend: #app/calculator/views.py from django.http import JsonResponse def concat_text(request): if request.method == 'POST': received_text = request.POST.get('text', '') result = received_text + ' =)' print(result) return JsonResponse({'result': result}) else: return JsonResponse({'error': 'Only POST requests are allowed'}) However, when I make a request from my React frontend, I'm receiving a 403 error (Forbidden). I am sending the text value via frontend by: const handleButtonClick = async (e) => { e.preventDefault(); try { const response = await fetch(`${URL}/calculator/calculator/`, { method: 'POST', headers: { 'Content-Type': 'application/json', }, body: JSON.stringify({ text }), }); The URL is simply the "http://localhost:8000". I have also defined the calculator urls: #app/calculator/urls.py from django.urls import path from .views import concat_text urlpatterns = [ path('calculator/', concat_text), ] My app urls: #app/urls.py from django.contrib import admin from django.urls import path, include from django.conf.urls.static import static from django.conf import settings from drf_spectacular.views import SpectacularAPIView, SpectacularSwaggerView from core import views as core_views … -

htmx: hx-target-error fails when hx-target defined (django python)

Joining Tables in Django ORM with Left Outer Join and Additional Condition
I'm trying to perform a left outer join between two models in Django using the ORM. I need to include an additional condition within the ON clause of the join to filter the results based on specific criteria. from django.db import models class Author(models.Model): id = models.BigIntField(primary_key=True) name = models.CharField(max_length=50) book_title = model.CharField(max_length=100) class Book(models.Model): title = models.CharField(max_length=100) author = models.ForeignKey(Author, on_delete=models.CASCADE, null=True, db_column='author') Is there a way to retrieve all the book objects along with the name of the author where the title and book_title are equal. The sql will look like: select title, author, name as author_name from book left outer join author on (book.author = author.id AND book.title = author.book_title) Since the table is very large ( 13m ) I cannot resort to raw query because I will lose the ability to use PageNumberPagination. I don't want to use extra because this may lead to problems in future. Is there any other way I can achieve the above sql using django orm?? -

django.core.exceptions.FieldDoesNotExist: Document has no field named 'header'
