title: getting 'wrong number of arguments (2 for 1)' when trying to access query results from SQL Server
body: <p>I'm using Ruby 2 and Rails 4 and trying to connect to a sql server instance using the Tiny_TDS and activerecord-sqlserver-adapter gems. It seems to connect to the database without a problem but when I try to access the returned data i get an error that says:</p>
  
  <pre><code>wrong number of arguments (2 for 1)
  </code></pre>
  
  <p>This is my first time trying to access sql server using Rails so I might be doing it wrong. Anyone know what I'm messing up?</p>
  
  <p>My controller has this call in it:</p>
  
  <pre><code>@epeople = Eperson.where("status = ?", "A")
  </code></pre>
  
  <p>In my view I have the following (if i remove this from the view the page loads fine):</p>
  
  <pre><code>&lt;% @epeople.each do |person| %&gt;
    &lt;%= person.firstname %&gt;&lt;br&gt;
  &lt;% end %&gt;
  </code></pre>
  
  <p>The eperson.rb model file:</p>
  
  <pre><code>class Eperson &lt; ActiveRecord::Base
    establish_connection(:other_db)
    self.table_name = 'EM'
  end
  </code></pre>
  
  <p>In my database.yml I have defined "Other_db" as follows:</p>
  
  <pre><code>other_db:
    adapter: sqlserver
    mode: dblib
    database: mydatabase
    username: 'lapuser'
    password: '(omitted)'
    host: reports
