How to get send_file working?

[mbhnyc]

Hey guys-

Hoping this is an easy one.. the APIs I'm building requires a facility to upload and download files, but i'm having trouble getting send_file to work (not including the right stuff).

Or is there a better way to support file sending?

Right now, i'm including

  include ActionController::Instrumentation
  include ActionController::Streaming
  include ActiveSupport::Notifications

In my controller (which inherits from RB)

But running my download method results in this error:

{"error":"system","error_description":"super: no superclass method `send_file' for #<AssetsController:0x007f89f42a5eb0>"}

I see the super call in instrumentation.rb, but not sure what else needs to be included.

Ideas? And curious how I'd have debugged this on my own..

Looking at the code for actionpack and the area, try including Instrumentation post-Streaming - basically, for the super to work, it needs the send_file method to be defined first, which is what including ActionController::Streaming will do.

E.g, try this and let me know if it works:

  include ActionController::Streaming
  include ActionController::Instrumentation
  include ActiveSupport::Notifications

Got it, it's actually include ActionController::DataStreaming, the rest of the includes aren't necessary.
