  1. POSuppress closure return value in ruby on rails erb file
    text
    copied!<p>I have a simple erb template that pulls information from a (Grit) git repository. It displays the information just fine, but it also displays the return value of the closure which is the array of commits I'm iterating through. I found a similar question <a href="https://stackoverflow.com/questions/3648264/how-can-i-prevent-the-printing-of-the-return-value-of-a-closure-in-rails">here</a>, but the solution does not change my output at all.</p> <pre><code>#controller method for home def home @repo = Repo.new("/home/matt/gitrepo") end #home.html.erb &lt;%= @repo.commits[1..3].each do |commit| %&gt; &lt;%= content_tag(:div, "#{commit.author}", :class=&gt;"author") %&gt; &lt;% end %&gt; </code></pre> <p>the page output is </p> <pre><code>Matt Phillips Matt Phillips Matt Phillips [#&lt;Grit::Commit "e761477be972855b0c4273c1c7837baa25178210"&gt;, #&lt;Grit::Commit "18140c17632fae7dbf33cdd5e372f96ebe8104de"&gt;, #&lt;Grit::Commit "f7e8ee090bb3e8259627179287d1722c328b614f"&gt;] </code></pre> <p>How can I suppress the array? </p> <p>EDIT: Here's what it looks like in irb</p> <pre><code>ruby-1.9.2-p180 :011 &gt; include Grit =&gt; Object ruby-1.9.2-p180 :012 &gt; @repo = Repo.new("/home/matt/gitrepo") =&gt; #&lt;Grit::Repo "/home/matt/gitrepo/.git"&gt; ruby-1.9.2-p180 :013 &gt; @repo.commits[1..3].each do |commit| ruby-1.9.2-p180 :014 &gt; puts commit.author ruby-1.9.2-p180 :015?&gt; end Matt Phillips Owen Johnson Matt Phillips =&gt; [#&lt;Grit::Commit "e761477be972855b0c4273c1c7837baa25178210"&gt;, #&lt;Grit::Commit "18140c17632fae7dbf33cdd5e372f96ebe8104de"&gt;, #&lt;Grit::Commit "f7e8ee090bb3e8259627179287d1722c328b614f"&gt;] ruby-1.9.2-p180 :016 &gt; </code></pre>
