Hi all,

In the rails api documentation I found,

<% form_tag '/posts' do -%>
<div><%= submit_tag 'Save' %></div>
<% end -%>

and tested this code successfully. What is the <% -%> syntax? Can someone explain this to me?

Are there comprehensive references for what's new in rails 2.0 and the differences between .rhtml and .html.erb files?

Thanks in advance.

The extra dash means that ERb will remove any newlines succeeding that tag.

Regarding template names, take a look at this: http://stuff.lilleaas.net/how_rails_sel … _to_render . Do inform me if the article didn't answer your question!
