Topic: Var dump at the bottom of a page?

i am working with rails 3 i have the following model

class ContactController < ApplicationController  def index    @surveys = Survey.active  endend

my controller

class ContactController < ApplicationController  def index    @surveys = Survey.active  endend

and my view

<%= @surveys.each do |p| %>  <li><%=p.id %>-<%=p.name %></li><%end%>

my anticipated outcome is that it for each through the surveys variable outputting the id and name in a li. which it does however it also dumps the variable out at the bottom of the page.

1-Ben Hill Voter ID
[#<Survey id: 1, name: "Ben Hill Voter ID", is_active: true, user_id: nil, open_script: "Opening Script", voicemail_script: "Voice Mail Script", closing_script: "Closing Script", email_script: "Email Script", created_at: "2012-12-19 15:17:36", updated_at: "2012-12-20 03:46:35">]

Re: Var dump at the bottom of a page?

Remove the "=" symbol from your for statement

<%= @surveys.each do |p| %>  
  <li><%=p.id %>-
    <%=p.name %>
  </li>
<%end%>

Should be

<% @surveys.each do |p| %>  
  <li><%=p.id %>-
    <%=p.name %>
  </li>
<%end%>

The = sign in an opening erb tag indicates that whatever is in the  tag should be output to the screen which is why you are getting the dump
