ruby on rails - Trying to have a view & block have access to a variable from a another block that is used to determine which element number in array -


i newer rails: side navigation partial takes each step , provides icon , link it. current active step, have same icon in top navigation side navigation. however, <%= icon[i] %> not work since [i] comes different block in different view. how make active link top's navigation has same icon[i] side navigation without having access i? see below.

_side_navigation.html.erb

  <% icon= ["icon-link", "icon-bar-chart", "icon-edit", "icon-beaker","icon-link", "icon-bar-chart", "icon-edit", "icon-beaker"] %>       <% @step_list.each_with_index |step, i| %>      <% case step.media_type %>     <% when 'video' %>             <li class="<%= nav_active step %>">               <a href = "                   <i class='icon-info-sign icon-2x'></i>                   <span>video</span>                 </a>             </li>       <% when 'excel' %>             <li class="<%= nav_active step %>">                   <i class="<%= icon[i] %> icon-2x"></i> **<<i need [i] in other partial know element of array chosen**                   <span>step <%= %> </span>               </a>             </li>      <% else %>             <li class="<%= nav_active step %>">                   <i class="<%= icon[i] %> icon-2x"></i>                   <span>step <%= %></span>               </a>             </li>      <% end %>      <% end %>

_top_navigation.html.erb

<div class="area-top clearfix">         <div class="pull-left header">                 <% case @step.media_type %>               <% when 'video' %>                 <h3 class="title">                   <i class="<%= icon[i] %>"></i></i> <<<here problem since, not have access current "i" other block                   video                 </h3>                 <h5>                   video course here                 </h5>                <% when 'excel' %>                <h3 class="title">                 <i class="<%= icon[i] %>"></i></i>               excel             </h3>             <h5>               please use excel sheet below complete challenge.             </h5>           <% else %>            <h3 class="title">             <i class="<%= icon[i] %>"></i></i>               multiple choice                                           </h3>             <h5>               please choose selection below             </h5>           <% end %>      </div>

is there no natural order these steps? don't have 'i' can pass in when include partial (partial local variables)?

if not, sounds need smarter 'step' object aware of index in workflow.

you place icon list in helper, so:

def icons   ["icon-link", "icon-bar-chart", "icon-edit",    "icon-beaker","icon-link", "icon-bar-chart",    "icon-edit", "icon-beaker"] end

gets out of view.

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
