#Django How to fetch data with permissions.IsAuthenticatied in views.py using Postman?
I'm trying to fetch data with my Django Restframework API endpoints.

mod_wsgi on Python 3.10 does not update Django templates without Apache restart
I have been running a Django server on Python 3.8 with Apache and mod_wsgi for some time now, and decided it was time to upgrade to Python 3.10. I installed Python 3.10 on my server, installed the Django and mod_wsgi packages, copied the 3.10 build of mod_wsgi.so to Apache's modules folder, and everything works great ... however, it seems with this build of mod_wsgi, changes to template files do not take effect unless I restart Apache. As an example, I added a random HTML template file to my website, and started the server with some initial text in that template. Running on the Python 3.8, I am able to change the contents of that template (e.g. echo "More Text" >> test_template.html) and upon refreshing my browser the new text will show up. However doing the same test in 3.10, the new text will not show up. I have tried different browser sessions and hard reloading, it is not a caching issue on the client side, and looking at the response sizes in Apache's access log confirms the data being sent to the client changes in 3.8 but not in 3.10. I have stood up a test server to isolate the … -
Need random number generated in html for embedding into iframe
I am using this embed code for a site. The site is a Django site. I apologize if my terms are wrong, I'm not a developer. . Periodically I return to the site and the graph will not display, but the logo from the host site does. I suspect that it's a caching issue. I tried "no-store" but I'm not sure if I pasted it in properly. I want to add a random number generator to the embed code. In my mind that would be similar to a refresh - again, not a programmer. Django strips css and possibly more. Can anyone either solve my problem or write the random number generator to make the "border-width" 1, 2, or 3? Here is my site with the bug. https://www.twelvebridges.com/twelve-bridges-market-report/. I encounter the bug on Chrome on a macbook. Never the first visit and a refresh solves it every time. I tried "no-store" but probably in the wrong place. I tried Classic Cache Killer as a Chrome extension on my site. I added a gif on the site even though I cannot really articulate what I thought that would accomplish. -

Django - FileField - PDF vs octet-stream - AWS S3
I have a model with a file field like so: class Document(models.Model): file = models.FileField(...) Elsewhere in my application, I am trying to download a pdf file from an external url and upload it to the file field: import requests from django.core.files.base import ContentFile ... # get the external file: response = requests.get('<external-url>') # convert to ContentFile: file = ContentFile(response.content, name='document.pdf') # update document: document.file.save('document.pdf', content=file, save=True) However, I have noticed the following behavior: files uploaded via the django-admin portal have the content_type "application/json" files uploaded via the script abobe have the content_type "application/octet-stream" How can I ensure that files uploaded via the script have the "application/json" content_type? Is it possible to set the content_type on the the ContentFile object? This is important for the frontend. Other notes: I am using AWS S3 as my file storage system. Uploading a file from my local file storage via the scirpt (i.e. using with open(...) as file: still uploads a file as "applicaton/octet-stream" -
Recommended Books & Videos for Vue, Javascript, NUXT, Django

django and nextjs shared authentication
I am building a new front end with nextJs for my Django App. I have been splitting the development to keep all the dashboard running on Django, while the rest runs on nextJs. nextJs is running on domain.com the existing django will be running on dashboard.domain.com I have setup all the Rest authentication for NextJs and is working fine. Now what I'm trying to achieve is when you login from domain.com you don't need to authenticate to the dashboard and reuse the same authentication. Django seems to have some cookie authentication and I'm using JTW for NextJS. What would be my options to solve this dilemma? -
Django: How to write a function based view used for URL with parameter
I am learning Django, using function based views, and I am struggling with the following: I have this path in urls.py path('user/<str:username>',views.UserProjectList,name='user-projects') that is supposed to show all the projects of the particular user (client).
