title: Ruby on Rails: Multiple Same Input Fields in Same Form
body: <p>Have a page where there are multiple input fields of the same thing, Posts. Right now, when a user enters in a question for, let's say 3 fields, the only one that saves to the database is the last one. Whereas, it should save all three and give them each it's own post_id. Also; if the user doesn't enter anything in for the other fields, it should not save in the database either.</p>
  
  <pre><code>&lt;%= form_for(@post) do |f| %&gt;
    &lt;%= f.text_field :content %&gt;
    &lt;%= f.text_field :content %&gt;
    &lt;%= f.text_field :content %&gt;
  &lt;% end %&gt;
  </code></pre>
