title: Capitalize only first character of string and leave others alone? (Rails)
body: <p>I'm trying to get Rails to capitalize the first character of a string, and leave all the others the way they are. I'm running into a problem where "i'm from New York" gets turned into "I'm from new york." </p>
  
  <p>What method would I use to select the first character?</p>
  
  <p>Thanks </p>
  
  <p><strong>EDIT:</strong> I tried to implement what macek suggested, but I'm getting a <em>"undefined method `capitalize'"</em> error. The code works fine without the capitalize line. Thanks for the help!</p>
  
  <pre><code>def fixlistname!
    self.title = self.title.lstrip + (title.ends_with?("...") ? "" : "...")
    self.title[0] = self.title[0].capitalize
    errors.add_to_base("Title must start with \"You know you...\"") unless self.title.starts_with? 'You know you'
  end
  </code></pre>
  
  <p><strong>EDIT 2:</strong> Got it working. Thanks for the help!</p>
  
  <p><strong>EDIT 3:</strong> Wait, no I didn't... Here's what I have in my list model.</p>
  
  <pre><code>def fixlistname!
    self.title = self.title.lstrip + (title.ends_with?("...") ? "" : "...")
    self.title.slice(0,1).capitalize + self.title.slice(1..-1)
    errors.add_to_base("Title must start with \"You know you...\"") unless self.title.starts_with?  'You know you'
  end
  </code></pre>
  
  <p><strong>EDIT 4:</strong> Tried macek's edit, and still getting an <em>undefined method `capitalize'"</em> error. What could I be doing wrong?</p>
  
  <pre><code>def fixlistname!
    self.title = title.lstrip
    self.title += '...' unless title.ends_with?('...')
    self.title[0] = title[0].capitalize
    errors.add_to_base('Title must start with "You know you..."') unless title.starts_with?("You know you")
  end
  </code></pre>
  
  <p><strong>EDIT 5:</strong> This is weird. I'm able to get rid of the undefined method error by using the line below. The problem is that it seems to replace the first letter with a number. For example, instead of capitalizing the <em>y</em> in <em>You</em>, it turns the <em>y</em> into a 121 </p>
  
  <pre><code>self.title[0] = title[0].to_s.capitalize
  </code></pre>
