title: How can i integrate country_select gem with best_in_place editing
body: <p>I am using the <a href="https://github.com/bernat/best_in_place" rel="nofollow">best_in_place</a> gem to edit records inline and <a href="https://github.com/purcell/country-select" rel="nofollow">country_select</a> to render a list of countries to select from. When using best_in_place to edit a select field i do this:</p>
  
  <pre><code>&lt;%= best_in_place(@home, :country_name, :type =&gt; :select, :collection =&gt; [[1, "Spain"], [2, "Italy"]]) %&gt;
  </code></pre>
  
  <p>Now i like to get a list of all the countries that country_select has and pass that into the collection parameter.
  The country_select gem provides a simple helper to render the select field:</p>
  
  <pre><code>&lt;%= country_select("home", "country_name") %&gt;
  </code></pre>
  
  <p>I would like to replace the :collection parameter in best_in_place helper to include the list of countries provided by country_select. I know that best_in_place expects the [[key, value], [key, value],...] input into :collection, but i am not sure how to do this. Please advise. Thanks</p>
