In the .rhtml or in the controller

Ruby

Hi list
I’v been wondering how to make an ‘each’ or a loop or something so I
don’t
have to write this code N times:

Imagen 0
<%= link_to_remote image_tag("/generate/imagen/0"), :url => {:action=> "generate", :id => 0}, :update => "show_div" %>
<%= draggable_element :dragg0, :handle => "'handler0'" %>
Imagen 1
<%= link_to_remote image_tag("/generate/imagen/1"), :url => {:action=> "generate", :id => 1}, :update => "show_div" %>
<%= draggable_element :dragg1, :handle => "'handler1'" %>

the same for N images

As you can see, it’s just the same code but the Id of the image and a
position. But If I put this code in the controller, I can’t create
those
<%= %> tags, they won’t be recognized. Or at least it didn’t for me.

Any idea, shall I make it in the controller? it’s there a way to do it
in
the .rhtml?

I’ve come to this

<% 0.upto(7) { |x| %>
  <div id="dragg<%= x %>" class="green box"

style=“position:absolute;top:<%= 190+((x / 4)*195) %>px;left:<%= 55 + (x
*
195) %>px”>

Imagen <%= x
%> <%= check_box_tag “cruzar”+x.to_s%>
<%= link_to_remote
image_tag("/generate/imagen/"+x.to_s), :url => {:action=> “generate”,
:id =>
x}, :update => “show_div” %>
<%= draggable_element “dragg”+x.to_s, :handle =>
“'handler”+x.to_s+"’"
%>
<% } %>

Someone out there might be needing this. :slight_smile: Just be careful with the use
of
<%= x %> and simply ‘x’ (without the quotes) or x.to_s
