During development we always need to print the objects in views for debug. In Rails, there are two ways you can print the Ruby objects.

• <%= debug @an_object %>
• <%= @an_array.inspect %>

 

Assume you got the following variables in the view

• @service – One single service
• @services – An array containing many services

 

Print it in the view

<p>Debug</p>
<%= debug @service %>
<div class="aligncenter" style="width:400px;height:0;border-top:4px groove #008000;font-size:0;">-</div>

<p>Map</p>
<% @services.each do |x| %>
  <%= x.inspect %><br/>
<% end %>
<div class="aligncenter" style="width:400px;height:0;border-top:4px groove #008000;font-size:0;">-</div>

 

See what you get
