Assign each value using different loops in python
Hi I got a loop where I get different parameters (age, date, role, etc.), and I got an array where I get these values. How can I assign each value to eache parameter. I'll add some code below I tried this but obviosly didn't work parameters = Parametros.objects.filter(job_id=job.id) if request.method == 'POST': for parameter in parameters: #Update parameters params = request.POST.getlist('parameter') for i in range(len(params)): cursor.execute("UPDATE Jobs_parametros SET parameter_value='" + params[i] + "' WHERE parameter_name='" + parameter.parameter_name + "' AND job_id=" + str(job.id)) Here we can see parameters where I'm assigning parameter.parameter.name for the differente names. After that we can see the array where I get the values called "params". I want to assign each value I get form params to the name of the parameter to execute the code showed in the last line The result that I got with the code showed is each parameter name with the last value I added. The values are updated but only take the last value in my form and didn't assigned my values like the date and age for eache parameter name -
django foreign key filtering in admin panel

If someone has another way to do it no problem, that was a junior try, waiting for your advice. -
How can I run Django on a subpath on Google Cloud Run with load balancer?
I'll preface by noting that I have a system set up using Google Cloud Run + Load Balancer + IAP to run a number of apps on https://example.com/app1, https://example.com/app2, etc, and up to now I've only deployed Streamlit apps this way. The load balancer is directing traffic to each app in Cloud Run according to subpath (/app1, ...), and I used the --server.baseUrlPath=app2 option of streamlit run with no problems. Now I'm trying to get a 'hello, world' Django 4.1.5 app running on https://example.com/directory, and I can't seem to get the routes right trying differing suggestions here, here, and here. The Dockerfile ends with CMD exec poetry run gunicorn --bind 0.0.0.0:${PORT} --workers 1 --threads 8 --timeout 0 example_dir.wsgi:application First, the canonical solution. I added FORCE_SCRIPT_NAME = "/directory" in settings.py. Here's example_dir/urls.py: urlpatterns = urlpatterns = [ path("admin/", admin.site.urls), path("", include("directory.urls")), ] and here's directory/urls.py: urlpatterns = [ path("", views.hello, name="hello"), ] Visiting https://example.com/directory returns Page not found (404) Request Method: GET Request URL: http://example.com/directory/directory Using the URLconf defined in example_dir.urls, Django tried these URL patterns, in this order: 1. admin/ 2. [name='hello'] That Request URL is surprising and weird. Adding either USE_X_FORWARDED_HOST = True or SECURE_PROXY_SSL_HEADER = ('HTTP_X_FORWARDED_PROTO', 'https') or … -

404 error when requesting a file that exists
I'm trying to deploy a Django project using a VPS - it uses Apache and mod_wsgi. (It works fine locally). My homepage is displayed, but no static file is found, leading to a goofy display. I have configured my static files this way : settings.py : STATIC_ROOT = os.path.join(BASE_DIR, 'static') STATIC_URL = '/static/' call in template : ` ` After that I ran collectstatic, which created a "static" folder on root, as expected. I have checked via SSH and FTP, it is there (see screenshot 1 : ), with the correct permissions. The URL to access it should then be : /static. But I get this 404 error, even though my explorer seems to look for the correct adress (see screenshot 2 : ) I have only basic academic knowledge on this topic, but I simply don't understand how can I get a 404 when requesting a file that seems to exist. I will take any suggestion, since I've tried everything I could think of. Thank you very much ! Also, I added this in urls.py : urlpatterns = [ path('', home, name='home'), path('output/<str:region>/<str:summoner_name>', output, name='output') ] + static(settings.STATIC_URL, document_root=settings.STATIC_ROOT) I didn't think this was necessary, but tried anyway.

Google Sheets Python Client gives indeterministic behavior
I have created a Django project with uses Google Sheets to store some data. When I make a request to an endpoint (/ca/register), sometimes the request passes successfully with a new ca object being created in the database, and its details being added to the corresponding Google Sheet too.
