title: Simple form wrong input type on Heroku
body: <p>I have a simple_form that works perfectly in development. Yet when I push to Heroku one attribute's input type changes from checkbox to text.</p>
  
  <p>The attribute is named "Dorm", and it's in the Room model.
  So I typed this line in both the Dev and Heroku consoles:</p>
  
  <pre><code>Room.columns_hash["dorm"]
  </code></pre>
  
  <p>Here is what I got in each one:</p>
  
  <p>Development:</p>
  
  <pre><code> =&gt; #&lt;ActiveRecord::ConnectionAdapters::SQLiteColumn:0x000000058be6d8 @name="dorm", @sql_type="boolean", @null=true, @limit=nil, @precision=nil, @scale=nil, @type=:boolean, @default=nil, @primary=false, @coder=nil&gt; 
  </code></pre>
  
  <p>Heroku:</p>
  
  <pre><code>=&gt; #&lt;ActiveRecord::ConnectionAdapters::PostgreSQLColumn:0x00000005755c10 @name="dorm", @sql_type="boolean", @null=true, @limit=nil, @precision=nil, @scale=nil, @type=:boolean, @default=nil, @primary=false, @coder=nil&gt;
  </code></pre>
  
  <p>And this is the line i'm using on my form:</p>
  
  <pre><code>= f.input :dorm,input_html: {class: 'dorm'}
  </code></pre>
  
  <p>The attribute's sql_type and type are correct in both environments (boolean). Why am I getting a text input in Heroku?</p>
  
  <p>Appreciate all and any help!</p>
