Does anyone know how I can fix this? I haven't used docker in the last few months (3-4) and yesterday I updated my docker and now this is happening. Now I don't know if is this because of an update or something else.

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:

sqlalchemy.exc.OperationalError: (sqlite3.OperationalError) no such table: Users
SQL: SELECT "Users".id AS "Users_id", "Users".email AS "Users_email", "Users".password AS "Users_password", "Users".option_1 AS "Users_option_1", "Users".option_2 AS "Users_option_2", "Users".option_3 AS "Users_option_3"
FROM "Users"
WHERE "Users".email = ?

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 :)

Is it possible to set the USERNAME_FIELD to email without having to build a custom manager and forms from scratch?

Im trying to setup a user model with an added birthday field and remove the username field. Can I do this using the usercreation forms and built in manager? Or would I still have to create my own from scratch

Creating a webp image on post_save

Hi everyone,

I've figured out how to create a webp image in my /media/ folder within the correct directory. Now, I'm needing to save this image to a field that i've crated on my model.

def create_webp_image(sender, instance, *args, **kwargs):

image_url = instance.image.thumbnail['1920x1080'].url

path = "http://localhost:8000" + image_url
response = requests.get(path, stream=True)

img = Image.open(BytesIO(response.content))

#build filepath
position = path.rfind("/") + 1
newpath2 = path[0:position].split('/media/')[1]

#get name of file (eg. picture.webp)
name_of_file = path[position:].split('.')[0] + ".webp"

#get directory
image_dir = os.path.join(settings.MEDIA_ROOT, '')

Workaround ALLOWED_HOSTS for a specific route for startup probe?

I am deploying a Django app to a kubernetes cluster. I want it to have a startup probe, which will basically just be a view that checks the database connection and returns a 200 response.

I'm having trouble because kubernetes will make a request directly to the pod IP with the pods hostname. Additionally, the kubernetes config is kind of out of my hands. I'd rather solve the problem by having a looser Django view than monkeying with the infrastructure code.

Is there a way for a single route / view to ignore the hosts whitelist?
