title: How would I save multiple records at once in Rails?
body: <p>How would I save this array in one call with Rails?</p>
  
  <pre><code>tax_rates = [{
    :income_from =&gt; 0
    :income_to  =&gt; 18200
    :start =&gt; "01-07-2013"
    :finish =&gt; "30-06-2014"
    :rate =&gt; nil
    :premium =&gt; nil
    },{
    :income_from =&gt; 18201
    :income_to  =&gt; 37000
    :start =&gt; "01-07-2013"
    :finish =&gt; "30-06-2014"
    :rate =&gt; 0.19
    :premium =&gt; nil
    },{
      :income_from =&gt; 18201
      :income_to  =&gt; 37000
      :start =&gt; "01-07-2013"
      :finish =&gt; "30-06-2014"
      :rate =&gt; 0.19
      :premium =&gt; nil
      }]
  </code></pre>
  
  <p>Can I just call <code>Rails.create(tax_rates)</code>?</p>
  
  <p>Also, is there a way to remove duplicate symbols so they look neater?</p>
