title: Rails debug method only outputs !binary values
body: <p>I have scoured the internet as best I can for this problem, but I am completely shafted by the keyword !binary as search engines (including stackoverflow's internal search!) strip the exclamation mark. </p>
  
  <p>I am working through the Rails tuorial at <a href="http://ruby.railstutorial.org" rel="noreferrer">http://ruby.railstutorial.org</a> - whcih has for the most part been an excellent resource. One of the useful things that I have at the bottom of my application.html.erb page is:</p>
  
  <pre><code>&lt;%= dump(params) %&gt;
  </code></pre>
  
  <p>I am told that a particular scenario should output the following:</p>
  
  <pre><code>--- !map:ActiveSupport::HashWithIndifferentAccess
  commit: Sign in
  session: !ActiveSupport::HashWithIndifferentAccess 
    password: ""
    email: ""
  authenticity_token: BlO65PA1oS5vqrv591dt9B22HGSWW0HbBtoHKbBKYDQ=
  action: create
  controller: sessions
  </code></pre>
  
  <p>Instead I get the following:</p>
  
  <pre><code>--- !ruby/hash:ActiveSupport::HashWithIndifferentAccess
  !binary "dXRmOA==": ✓
  !binary "YXV0aGVudGljaXR5X3Rva2Vu": ItPS/PZ+avYOGD2ckict1urJpatw1HinrVyk385/Yt8=
  !binary "c2Vzc2lvbg==": !ruby/hash:ActiveSupport::HashWithIndifferentAccess
    !binary "dXNlcm5hbWU=": ''
    !binary "cGFzc3dvcmQ=": ''
  !binary "Y29tbWl0": Sign in
  action: create
  controller: sessions
  </code></pre>
  
  <p>Which is far less helpful.</p>
  
  <p>I am assuming that rails has the option of outputting data as it is in memory (i.e. binary form) or it can decode the data and display it in plain text.</p>
  
  <p>I am obviously getting the correct data, just in the wrong form.</p>
  
  <p>The question is how do I get the plain text version?</p>
  
  <p>The second question is why the heck does a site like stackoverflow not have a mechanism to include special characters in searches? Fundamental Fail IMO </p>
