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 figured it out. There is a raw_post method in AbstractRequest.

So you can do this to parse the raw post params:

def raw_post_to_hash
  request.raw_post.split(/&/).inject({}) do |hash, setting|
    key, val = setting.split(/=/)
    hash[key.to_sym] = val
    hash
   end
end

and then just call raw_post_to_hash[:action] to access the original action param or any other param. There is probably an easier way.

Answer 2

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
