I have a Django rest api which you can upload a file and an id. I want to
call a function when the post button (check the image if you want) is
pressed in order to do some stuff with the uploaded file. How can I do this
in django rest platform? Thanks in advance.

Little bit more detailed information: I will upload a text file and when I
pressed the post button, I want a function to start (which reads file's
contents and finds a string in there).
