Django i18n, using template inside python string, how to translate
I need to translate some emails in a django app and I was wondering what is the best way to tag for translation something like this: subject_template = ( 'Enlèvement programmé le {{ pickup.pickup_date|date:"l d F"|lower}} {{ pickup.timeslot }} - ' + "{{ pickup.display_id }}" ) This is a part on an email in a pythons script, however template are used inside the string, so I cannot really use gettext isn't it ? Maybe one of you ended up in a similar situation, if you have a solution that would be neat. -

Integration the bank payment system
I am trying to integrate the Bank's payment system on my Django-based website. As it said in documentation, I need to send parameters to their server (and then the new window should appear and the client should fill his card credentials there). Documentation (part 1): Documentation (part 2): Documentation (part 3): I am new in integration such services (payment) and need some help or broad explanation what to do, why do to that, and how. Additionally, I was pretty sure that the following code wouldn't work fine but why. import requests def send_request(): url = 'https://ecomm.pashabank.az:18443/ecomm2/MerchantHandler/?command=v&amount=5&currency=932&client_ip_addr=167.184.1.132&msg_type=SMS' response = requests.post(url) print(response) send_request() causes raise SSLError(e, request=request) requests.exceptions.SSLError: HTTPSConnectionPool(host='ecomm.pashabank.az', port=18443): Max retries exceeded with url: /ecomm2/MerchantHandler/?command=v&amount=5&currency=932&client_ip_addr=167.172.184.123&msg_type=SMS (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:1123)'))) Overall, I need help of everything happening behind the scenes.

Role choice field data ins't saved for UserRegsitrationForm django
The following error message appears after I submit the SignUpform: 'NoneType' object has no attribute '_inc_path' This issue is related to the role choice field of my CustomUser model. The models function perfectly without the role field and all forms are displayed and saved correctly.

Prevent Url Form from clearing out
I am currently working on a Django project and wanted to create a form that includes the invitation link as the initial URL and a field for the maximum usage of that link.

Any ideas on how to prevent this or is there another way to solve this problem. form in forms.py view in views.py functions in functions.py -

Paramiko exec_command, can't make code awaits for task to be completed
I am building a django app under docker. In the views I call a task where paramiko makes a ssh connection from a container to another to run a third party app. The problem is that during the call to the other container I zip the 'results' folder and move it to another place.

Django threads working differently with manage.py and gunicorn
I am working in a Django project with REST API that needs to work without a database, so the data is saved in a static dict. The app uses two different datasets that provide information about roads. One of the datasets provides some static data (it might be updated, at most once or twice a year), and the other one provides dynamic data (updated every 5 minutes). The dict will contain an element for each road, each element is created when the static dataset is read, and is updated with the dynamic data every 5 minutes when the dynamic dataset is read. Inside the APP, the static data is read by the main thread, and then is updated once a month by a second thread. The dynamic data is read by a third thread every 5 minutes. When a GET request is sent to the REST API, it should return the content of this dict. It works fine when the app is executed through the "manage.py runserver" command. However, after exporting the project to a docker image (that uses gunicorn), when the app is running, the GET request doesn't get the dynamic data on response, but only the static one … -

Does race condition(lost update or write skew) happen in Django admin?
In Django views, we can use select_for_update() to prevent race condition(lost update or write skew) so race condition doesn't happen in Django views with select_for_update(). But, even though I googled, I couldn't find any information saying "in Django admin, race condition doesn't happen or select_for_update() is used to prevent race condition". So, in Django admin, does race condition happen? If so, are there any ways to prevent race condition in Django admin? If not, is select_for_update() or other way used to prevent race condition in Django admin? and can I see the code for me? -

Dynamic updating & HTMX
I have this form setup This is what I want to happen; when the user selects an "Indoor Manufacturer" it then provides a list of "Indoor Models" that belongs to the "Indoor Manufacturer". The same thing for "Outdoor Manufacturer" & its Corresponding "Outdoor Models" I can get the above to work fine using HTMX using my code below However, the next step is to add to the HTMX the "Indoor/ Outdoor Same" checkbox, which will copy the data from "Indoor Manufacturer" to "Outdoor Manufacturer".

where to store 1TB media-file in Django project?
I have a Linux server and a Django project on it. My website opens files that can have enormous sizes. Like 100-500GB or even 1,2TB. Now I just drag and drop these files to "Staticfiles" folder inside my Django project. I use Filezilla for this. But is it a general practice to store such big files inside the Django file system? Or there is a way to store them somewhere outside? Because I think that there should be some "storage" independent from the Django project where I can store my big files. If you have experience with that It would be great if you share your opinion.
