How to check if there is any file field in rails request parameters

Question

I am making a logging system which keeps track of all the request the web server is getting. How do I check if any of the requests contain any file i.e. any file upload action?

Answer 1

Maybe check what is your request mime type.

request.content_mime_type.symbol
=> :multipart_form

If that returns :multipart_form you can go through the params values and search for kind of ActionDispatch::Http::UploadedFile.
