There are quite a few of these question in stackoverflow none of which have been able to help me. I am launching an amazon ec2 using rails and postgresql. I have it launched but keep getting the following error (I have done everything including rake db:migrate even everything here

):

When I run this locally it works fine. It is when I run it in my amazon ec2 instance that it keeps giving me this error. Any help would be greatly appreciated.
Also, here is the code in the index.html.erb file:
<!-- Portfolio Box -->
<ul class="list-unstyled row portfolio-box">
<% @recent.each do |campaign| %>
<li class="col-sm-4">
<%= link_to campaign.image.url, :class => "thumbnail fancybox", data: { rel: "gallery" }, title: campaign.title do %>
<%= image_tag campaign.image, :class => "full-width img-responsive" %>
<span class="rounded-x portfolio-box-in">
<i class="fa fa-search-plus"></i>
</span>
<% end %>
<div class="headline-left margin-bottom-10"><h3 class="headline-brd"><%= campaign.title %></h3></div>
<small class="project-tag"><i class="fa fa-tags"></i><%= raw campaign.tags.map{ |t| link_to t.name, campaigns_path(tag: t.name)}.join(', ') %></small>
<p><%= truncate(campaign.description, length: 130) %> </p>

Figured it out. Thanks to @mu is too short I assumed I was connected to the the correct database. When I looked in the postgressql terminal:
postgres=# \dt;
List of relations
Schema | Name | Type | Owner
--------+-----------+-------+----------
public | campaigns | table | postgres
(1 row)
It would show me this so I assumed I was connected but somehow I created a campaign database in the postgres database and not the "martin_development" database where I needed it to be created. When I connected to the "martin_development" database I found that the campaigns table was not there which caused this error. The other issue was my migrations, it turns out that I created the campaigns table in razorsql and not through rails so no migrations were created to run with rake:db migrate
. I had to rails g model campaign
... in rails to create the migration. Once I ran rake:db migrate the page worked again and the error disappeared.
Learned two lessons
Double check I am on the right database.
Create tables inside of rails not through an outside database ui as the migration will not be created.
