title: Paperclip not showing image even though URL/images in correct places
body: <p>Using Paperclip to attach avatars to User profiles for my rails application. I followed the instructions on the paperclip github to initialize and attach to my app. </p>
  
  <p>I have an image in the public/images/medium/missing.png and for both cases (when I upload or when I fallback on the default) I get no image. I've checked my directory and there is an image where it says it is looking but does not grab it. Additionally when I have tried uploading images, I know the image is uploaded correctly because when calling the User in rails console shows all the information properly attached. </p>
  
  <p>I am calling the image in my view like:</p>
  
  <pre><code>&lt;%= image_tag(@blog.user.avatar.url(":medium"), :class =&gt; "image-circle avatar") %&gt;
  </code></pre>
  
  <p>my Paperclip declaration in the User model looks like the following:</p>
  
  <pre><code>has_attached_file :avatar, :styles =&gt; { :medium =&gt; "300x300&gt;", :thumb =&gt; "100x100#"}, :default_url =&gt; "/public/images/:style/missing.png"
  validates_attachment_content_type :avatar, :content_type =&gt; /\Aimage\/.*\Z/
  </code></pre>
  
  <p>Really not sure what is going on. The route errors that appear when I inspect the improperly loaded image point directly to the image in my local server. And the fact that it can't grab either the missing or the uploaded file also has me at a loss. Any help would be super appreciated!!</p>
  
  <p>And for good measure the output when I examine a user with an uploaded avatar:</p>
  
  <pre><code>avatar_file_name: "11390219_10206114805925816_6595348111261743639_n.j...", avatar_content_type: "image/jpeg", avatar_file_size: 101926, avatar_updated_at: "2015-07-10 18:51:44"&gt; 
  </code></pre>
  
  <p>Thanks in advance!</p>
  
  <p>EDIT</p>
  
  <p>This is the URL that is providing the 404 error: </p>
  
  <pre><code>http://localhost:3000/images/medium/missing.png 
  </code></pre>
  
  <p>while in my local directory it goes "root/public/images/medium/missing.png"</p>
  
  <p>not sure how its not grabbing it, unless I am just missing something really obvious somewhere. (i tried hard routing the public in there as well, but to no avail).</p>
