    copied!<p>Alright. So I have a table called contacts. In this table I have people and there contact information and how their preferred method of contact (Phone, Address, Email, or Fax). I want to be able to have ruby output a list of said people in a manner I could copy paste into a email address bar or such. </p> <pre><code>&lt;% @contacts.each do |contact| %&gt; &lt;%=h contact.contact_name %&gt; &lt; &lt;%=h contact.preferred_method %&gt; &gt;, &lt;% end %&gt; </code></pre> <p>This works, but it doesn't do what I want it to do and I didn't expect it to. So for a list of people whos preferred choice is email it outputs the list as.</p> <p>Mike &lt; Email >, Joe &lt; Email >, John &lt; Address >, Sarah &lt; Phone ></p> <p>instead of</p> <pre><code>Mike &lt;mike@yahoo.com&gt;, Joe &lt;joe@aol.com&gt;, John &lt;2014 Street&gt;, Sarah &lt;111-111-1111&gt; </code></pre> <p>It's calling the preferred_method, but what I actually want it to do is...</p> <pre><code>&lt;% @contacts.each do |contact| %&gt; &lt;%=h contact.contact_name %&gt; &lt; &lt;%=h contact.&lt;%=h contact.preferred_method %&gt; &gt;, &lt;% end %&gt; </code></pre> <p>So I would get contact.address or contact.phone depending on their preferred_method. But obviously that doesn't work. So I thought of trying to assign <code>&lt;%=h contact.preferred_method %&gt;</code> to a variable.</p> <pre><code>x = contact.preferred_method </code></pre> <p>And then have</p> <pre><code>&lt;% @contacts.each do |contact| %&gt; &lt;%=h contact.contact_name %&gt; &lt; &lt;%=h contact.x %&gt; &gt;, &lt;% end %&gt; </code></pre> <p>but that doesn't work either.</p> <p>Any help would be appreciated.</p> <p>Mike</p>
