Django Channels error appears in separate Django project (broken pipe error)
I'm relatively new to ASGI and Django Channels, so this is probably a very basic question. I got ASGI running thanks to Django Channels in one of my Django projects and it works fine. I then want to work on my old project, which doesn't yet use ASGI. I kill the debug server running locally on 127.0.0.1, switch environments (in an entirely new shell window) and start the debug server running for the old project: (server) me@laptop server % ./manage.py runserver Watching for file changes with StatReloader Performing system checks...

Django: How to read an image sent using Dio from flutter
I'm a newbie to Flutter and trying to build a Flutter App. I want to upload an image from android device to django, process it and send the results back to flutter in a json format without saving the image anywhere. But I'm facing difficulty in reading image in django. However, the image is sent successfully from flutter. Here is my flutter code for sending an image using Dio : Future<void> _clearImage() async { try { String filename = imageFile!.path.split('/').last; FormData formData = FormData.fromMap({ "image": await MultipartFile.fromFile(imageFile!.path, filename: filename, contentType: MediaType('image', 'jpg')), "type": "image/png" }); Response response = await dio.post('http://192.168.43.63:8000/scan/', data: formData, options: Options( followRedirects: false, // will not throw errors validateStatus: (status) => true, headers: { "accept": "*/*", "Content-Type": "multipart/form-data", })); print(response); } catch (e) { print(e); } setState(() {}); } } Here is my code for django: file = request.FILES['image'] print(file) img = cv2.imread(file.read()) print(img) I'm getting the following error: img = cv2.imread(file.read()) TypeError: Can't convert object of type 'bytes' to 'str' for 'filename' Your help will really be appreciated.

Filter django QuerySet on subclassed type (multi-table inheritance)?
I'm looking for an efficient model manager method that uses the following class structure to generate the QuerySet described by code in views.py: #models.py from django.db import models class Super(models.Model): date_of_interest = models.DateField(...) # <other model_fields> class SubA(Super): # <other model_fields> class SubB(Super): # <other model_fields> class SubC(Super): # <other model_fields> #somewhere else (eg. views.py) ... query_set = Super.objects.filter(date_of_interest=today) qs_to_list = [e for e in query_set if hasattr(e, 'subb') or hasattr(e, 'subc')] I would like to keep qs_to_list a QuerySet, so I'm searching for a way to filter with a model manager, based on the type of subclass. As noted, I'm using multitable inheritance with abstract=False and implicitly using the OneToOneField created with this type of inheritance. Thanks! -

Not able to navigate between two templates in a Django application
I have a ran into a difficulty when navigating between different templates in a Django (v3.2) application. The app is called 'manage_remittance'. The default landing page (which uses template manage_remittance/templates/manage_remittance/view_remittance.html) for the app should show a list of items (list is not relevant at the moment), and at the top of that list there should be a link, leading to another page in the same app, which would allow to add new items to the list. The form that is invoked first is here: manage_remittance/templates/manage_remittance/view_remittance.html {% extends "root.html" %} {% load static %} {% load crispy_forms_tags %} {% url 'manage_remittance:remittance_add' as remittance_add %} {% block title %} VIEW REMITTANCES PAGE {% endblock title %} {% block content %} <div class="list-group col-6"> <a href="{{ remittance_add }}" class="list-group-item list-group-item-action shadow-mt list-group-flush list-group-item-dark text-light">Click here to add remittance data</a> </div> I want to be able to get to another template (manage_remittance/templates/manage_remittance/remittance_add.html), but the {{ remittance_add }} has no value. In addition, when I specify exact name of the html file (remittance_add.html) in the a href (see above), and click on it, I get a following error: Using the URLconf defined in sanctions_project.urls, Django tried these URL patterns, in this order: admin/ [name='login'] login/ … -
Problem while transferring data between POST request and GET in django
I have a select tag, and what my logic is that after the user selects an option, we would send that response and search through the db to find similar records. The problem is how to access that data. After the user has selected an option, I would take them to other page which is just a GET request page. So how to access the select tag data(which is a POST request data) on a GET request page. -

Can I expose the API URL to the public in a Python library?
I have built a Django API which has a lot of proprietary algorithms for analyzing stock portfolios. The API is hosted in AWS and this API is also connected to the website where I show the visualizations of the calculated metrics. I want to build a library to provide these metrics in Python like pandas. Users can install this package using pip install . In my Python library code, I would expose only the API URL and I will call the API with different parameters and endpoints. Paid users will get a unique access code in email using which only they can access the Python package functions. I don't want to expose my Django API code to the public as the analysis itself requires a lot of stock price data from the Database and also there are a lot of proprietary algorithms. Does the solution make sense? Should I hide the API URL or just leave it. -
