Dynamic view filename in intent response

[tsrivishnu]

Right now, by returning response in an intent handler renders the default speech.ssml.erb and display.text.erb. These files need to handle all the different conditions if the response needs to be different for different conditions. This will pollute the view file with some if clauses and sharing variables from intent. For example. Consider the following:

# Intent handler class
class Alexa::IntentHandlers::SaveBookmark < Alexa::IntentHandlers::Base
  attr_accessor :success
  def handle
     if some_condition
       @sucess = true
     else
       @success = false
     end
     return response
  end
end

# View - intent_handlers/save_bookmarks/speech.ssml.erb
<% if intent.success %>
   <s> You request is successfully processed. </s>
<% else %>
  <s>Unable to process your request.</s>
<% end %>

It would be nice if a the response method on intent handlers can accept the response filename argument so that there can be multiple view files for conditions.

In above example.

# Intent handler
def handle
     if some_condition
       @sucess = true
       return response(view_file: :success)
     else
       @success = false
       return response(view_file: :failure)
     end
  end

# View - intent_handlers/save_bookmarks/success.ssml.erb
   <s> You request is successfully processed. </s>
# View - intent_handlers/save_bookmarks/success.text.erb
   Succesfull. 

# View - intent_handlers/save_bookmarks/failure.ssml.erb
   <s> You request couldn't be processed. </s>
# View - intent_handlers/save_bookmarks/failure.text.erb
   Failed. Sorry!
