Ruby on Rails

To address the two responses: thank you, I took Colin's suggestion and
ran a log just trying to access a record:


2016-06-20T23:57:59.062266+00:00 app[web.1]: Completed 500 Internal
Server Error in 10ms (ActiveRecord: 3.5ms)

2016-06-20T23:57:59.064217+00:00 app[web.1]:

2016-06-20T23:57:59.064214+00:00 app[web.1]: 17: <h1
class="review_title"> <%= @professor.fullname %> </h1>


It seems to be having a problem with showing the name, I don't know why
this is a problem this page works fine on localhost. One possible thing
I can think of is that I created a column "firstname" in a recent
migration (still well before I pushed this to Heroku) could it be
possible that Postgres is using an earlier migration then SQLite?


This is my show.hm.erb where the offending method is:

<div class="col-md-6">
<h1 class="review_title"> <%= @professor.fullname %> </h1>
<ul class="list-unstyled">
<% if !@review.blank? %>
<li> <strong>Average Review: </strong><div
class="star-rating" data-score= <%= @avg_review %> </div></li>
<% end %>

<li><strong>School: </strong><%= @professor.school %></li>
<li><strong>Department: </strong> <%= @professor.department
%></li>
<li><%= "#{@review.length}" "
Review".pluralize(@review.length)%></li>
</ul>
</div>
