Hi guys, I want to save the current article id, but I don''t know how.
someone have an example?
Ex. I click on "show article", after that I click "edit

the editing is finished I want to click "back" and loading the show
page

Hey,

Depending on your code, you should be able to just do @article.id in
your view to access the current article''s id.  For a route you can
even drop the .id:

<%= link_to ''Edit this article'', :action =>
''edit'', :id => @article %>

and if you''re using map.resources, it''s even shorter:

<%= link_to ''Edit this article'',
edit_article_path(@article) %>

Hope that helps,

Steve

I don''t want to access to the current article.id but save it in the 
class and use it when I need to go back at the last article showed.
I don''t know where i can store it, in the application.rb or in the 
articles_controller.rb, and how store it!

Thanks

I tried this:
-in application.rb

  def current_article
  if @current_article
    return @current_article
  else @params[:id]
    return @current_article = @params[:id]
  end
  end

-in articles_controller.rb

  def show
    @article = Article.find(current_article)
  end

It works if i try <%= link_to ''show'', :action =>
''show'', :id => article
%>
but if I try <%= link_to ''show'', :action =>
''show'', :id =>
@current_article %>
it doesn''t work.

What is wrong? thanks
