Rails overwriting params value

Question

I'm trying to up receive updates on my Trello model when a change occurs, which I'm using their webhooks for. The problem is that one of the parameter's name is "action", which seems to be overwritten by Rails depending on the value in the Routes.rb. Is there any way to avoid this or do I just have to live with it?

Routes.rb

  match "/trello" => "trello_updates#index", via: [:get,:post]

Webhook reponse

Parameters: {"model"=>{...},"action"=>"index"}

Answer 1

You can write a middleware in initializers and update the params coming from trello webhooks. like below -

class TrelloWebhooks

  def initialize(app)
    @app = app
  end

  def call(env)
    request = Rack::Request.new(env)
    trello_action = request.params['action']
    request.update_param('trello_action', trello_action)
    status, headers, response = @app.call(env)
    [status, headers, response]
  end

end

Rails.application.config.middleware.use 'TrelloWebhooks'
