ruby on rails - RoR Impressionist capture external click -

i'm using impressionist gem record page views.
let's have question model , answer model:

question.rb:

class question< activerecord::base   has_many :answers   is_impressionable 

answer.rb:

class answer< activerecord::base   belongs_to :question   is_impressionable 

in questions\show.html.erb, have list of answers.
when user hovers on answer, see 2 links appear: details , go to.
details link opens answer show page (which provides more details) , records show impression , works correctly:

answers_controller.rb:

 impressionist(@answer) 

the go page tricker. when user clicks on link:

 <%= link_to "go to", :class => 'answer_link', :remote=>:true,        :data=>{outval: answer.type_url, cuid: answer.id.to_s, refval: user_question_path(@question.user, @question), txtval: answer.img_url} %>             <span class="small_image">                <%= image_tag(answer.img_url, :alt => 'go answer', :class =>'img_answer')  %>              </span>   <% end %> 

, run following jquery snippet:

 $('.answer_link').click (->     url_val=''     url_val = "http://api.somewebservice.com/api/click?key=abc123"     url_val += "&out=" + $(this).data('outval')     url_val += "&loc=" + $(this).data('refval')     url_val += "&cuid=" + $(this).data('cuid')     url_val += "&ref=" +  $(this).data('refval')     url_val += "&txt=" +  $(this).data('txtval')     window.open url_val   ) 

this works correctly , runs web service , opens returned external link in new window.
problem trying capture external click impression.
best way this? currently, when click external link, questions controller, show action runs.

specific question #1: "seems" correct in don't want go anywhere (another window has opened external link). correct use questions controller, show action , if params[:id]=="go to" stay put.

specific question #2: if correct, there way send impressionist :action_name (i'd send "go to" instead of default it's sending of "show":

specific question #3: if it's not correct, should doing? perhaps going answers controller, custom-defined "go_to"?

ok - have solution (not sure if it's best 1 works)

1. question.rb , answer.rb above stay same

2. to count impressions of answer show.html.erb page, still use in answer_controller, :

    impressionist(@answer) 

3. to count impressions when redirect answer, created new def in answer_controller:

   def visit_external_site   @answer= answer.find(params[:answer_id])   impressionist(@answer)   respond_to |format|     format.html {render :nothing => true, :status => 200}   end end 

(the part i'm not sure format.html (i don't want go anywhere still....)

1. my routes.rb has this:

   match '/:answer_id' => 'answers#visit_external_site', :as => 'visit_external_site' 

   1. the questions\show.html.erb page has now:

 <% @question.answers.each |answer| %>   <%= link_to url_for(:controller => :answers, :action => :visit_external_site, :answer_id => answer),                           :class => 'answer_link', :remote => true,                           :data => {outval:                                             answer.type_url, cuid: answer.id.to_s, refval:                                             user_question_path(@question.user, @question), txtval:                                             answer.img_url} %>                 <span class="small_image">                     <%= image_tag(answer.img_url, :alt => 'go answer', :class => 'img_answer') %>                 </span>               <% end %> <% end %> 

1. my jquery still same above

if has better way doing this, tell; i'm not sure if way "kosher"
