How to not use Rails action parameter in controller

Question

I am implementing a third party API for Shipworks in a Rails server and the Shipworks client app is posting an action param with Shipworks specific semantics.

Answer 1

I fell into this trap today and came with this solution in controller method. It's Rails 4.1:

if request.method == "POST"
  action = request.request_parameters['action']
else
  action = request.query_parameters['action']
end
