Django generate thumbnail with MoviePy, problem with Path

How to get the absolute path to a video, that works in development (Windows) and production (Ubuntu), ive tried almost everything, here is the closest I've gotten to a solution, I am trying to generate a thumbnail for a video when its posted.

from pathlib import Path
BASEDIR = Path(file).resolve().parent.parent
def generatethumbnail(instance):
filename = Path.joinpath(BASEDIR, 'media/videofiles')
print(filename)
thumbnail = VideoFileClip(str(filename)+instance.video.url)
name = instance.video.url + '.png'
time = random.randrange(60)
thumbnail.saveframe('media/uploads/thumbnail' + name, t=time,withmask=True)
instance.thumbnail = name

It never gives me a good path, its ether with '/' or with \\ .

MoviePy error: the file C:\Users\User 1\Desktop\django\lumen\media\videofiles/media/uploads/videofiles/22/29/Elvis-IfICanDreamOfficialLivePerformancefcw0WKp.mp4 could not be found! Please check that you entered the correct path.

Django admin actions for list entries

Django admin comes with custom actions for entries in a list. It works for both one value or multiple but is there any way we can add actions exclusively to an entry in the list ?

Something like the Record actions in the picture below?

Normal flask-redis works, but flask-caching w/redis ignores password

When I run this app, it works:

import redis

r = redis.Redis(password='no peeking')

r.mset({'test': 'TEST'})
x = r.get('test')

print(x)

But this one fails:

from flask import Flask
from flaskcaching import Cache

app = Flask(name)

cache = Cache(app, config={'CACHETYPE': 'redis', 'CACHEREDISPASSWORD': 'no peeking'})

cache.add('test', 'TEST')
x = cache.get('test')

print(x)

with the error "redis.exceptions.AuthenticationError: Authentication required."

Any ideas?

Django redirect doesn't work when trailing slash is there.

So I have a url pattern which looks like this

urlpatterns = [
path('register-user/', views.registerUser, name='registerUser'),
path('register-vendor/', views.registerVendor, name='registerVendor'),
path('login/', views.login, name='login'),
path('logout/', views.logout, name='logout'),
path('dashboard/', views.dashboard, name='dashboard'),
path('vendor-dashboard/', views.vendorDashboard, name='vendorDashboard'),
path('my-account/', views.myAccount, name='myAccount'),
]

and views

def myAccount(request):
user = request.user
redirectUrl = detectUser(user)
return redirect(redirectUrl)

def dashboard(request):
return render(request, 'accounts/dashboard.html')

def vendorDashboard(request):
return render(request, 'accounts/vendor-dashboard.html')

the detect user function detects and user type and returns respective URL

def detectUser(user):
if user.role == 1:
redirectUrl = 'vendor-dashboard/'

elif user.role == 2: redirectUrl = 'dashboard/'

elif user.role == None and user.is_superadmin:
redirectUrl = 'admin'

return redirectUrl

but when I see the website the URL is

Flask run fail after Python update

I updated my Python from version 3.9.2 to 3.11.1 on a Windows 10 machine. I reinstalled Flask and other modules I needed for the new Python version through pip and it seems that my apps work as normal when I use python -m flask run. However just flask run still looks for the old (and now uninstalled) Python 3.9 and of course fails as the system can't find the files. How can I fix this? I tried uninstalling it and reinstalling it with no success.

One think I have noticed, but I have no idea if this relevant or not, is that the old Python was installed under C:\\Program Files while the new one is only installed in AppData/Local even though I installed it for all Users. Plus I can't change the installation path in the setup program, even when running it as Administrator.

Operational error after changing the operating system

Dear Flask developers,

\-I built my flask app on WSL(Windows Subsystem for Linux) without a problem and it is working on WSL.

\-In order to test my app on a server environment I copied my app to an OpenBSD virtual machine on Hyper-V.

\-Ran my app on the local network.

\-I tried to connect from a different machine to the server(OpenBSD VM). Connected without a problem.

\-There is a login screen in my app and when I try to login as a user I got an operational error:

Deploying an application to “production” in AWA

I have a Django app. I totally messed up it’s configuration and I can’t get it running. Honestly, I have no idea how I got in running in the first place a year ago. I’m not comfortable at all with Apache etc.

I’d like to reset it up from scratch. Are there any great, detailed tutorials. I need to use my custom domain and SSL as well.

Please help :)
