Run or include gdal python scipt in Django
I am new (noobee) on Django. I have a python script that prints the times, X, Y of the dataset in a specific NetCDF file. import gdal netfile = gdal.Open('NETCDF:"E:/Jobs/statr.nc":tm25') print 'Band shape (T, Y, X): ', (netfile.RasterCount, netfile.RasterYSize, netfile.RasterXSize) How can I use this script in a Django project? For instance, if I have a button and an input box and on user click, show the script's output to the input box. Is there any way to include the script inside Django (view, template, etc)? Thanks in advance John -

React Django Application different ip adresses CORS issues
I try to deploy an APP1 application on an EC2 (whose IP address is app1_ip): the frontend is created with React and the backend is created with Django, django-rest-framework, gunicorn and nginx. The backend is the same as another APP2 application that is already deployed on a second EC2 (whose IP address is app2_ip). I have no trouble getting the second application to work and request its React frontend (located at port 3000 of app2_ip) on its backend (located at port 8000 of app2_ip). On the other hand, I have a lot of trouble requesting the backend of APP2 from the frontend of APP1. I'm missing something but I can't see what. I am looking to develop the cleanest production configuration possible. I have a login page that prompts the user to enter a password and a username. A request is then sent to the backend to verify these credentials. Fetch request from the login page used in the APP1 backend deployment : fetch(`https://{app2_ip}/token-auth/`, { method: 'POST', headers: { 'Content-Type': 'application/json' }, body: JSON.stringify(data) }) nginx.conf file used in the APP2 backend deployment upstream django { server backend:8000; } server { listen 80; server_name my_server_name return 301 https://{my_server_name}$request_uri; } server … -

How can I use django-clever-selects for filters instead of forms?
