    text
    copied!<p>I'm building a basic Rails 4 application, and seem to have hit a frustrating snag. I've been following the <a href="http://railscasts.com/episodes/253-carrierwave-file-uploads" rel="nofollow">CarrierWave Railscast</a>, and while I'm able to get images to show up on /image/show.html.erb, I've had some difficulties with getting any of the images I've uploaded to display in the gallery each image is associated with. </p> <p>The strange thing is, there aren't any errors logged. The page loads without any Rails errors coming up in the page or the terminal; the only way I know something is wrong is that the div that images are supposed to appear in doesn't show up at all.</p> <p>I'm really stumped about this. If you look, the .images div in the show action for galleries renders, but absolutely none of the sub-elements render at all. What am I doing wrong?</p> <p><a href="https://github.com/DeadSuperHero/DeadSuperHero" rel="nofollow">Source code here</a></p> <p><strong>app/models/image.rb</strong> </p> <pre><code>class Image &lt; ActiveRecord::Base belongs_to :gallery mount_uploader :image, ImageUploader end </code></pre> <p><strong>app/models/gallery.rb</strong></p> <pre><code>class Gallery &lt; ActiveRecord::Base has_many :images end </code></pre> <p><strong>app/uploaders/image_uploader.rb</strong></p> <pre><code>class ImageUploader &lt; CarrierWave::Uploader::Base include CarrierWave::RMagick storage :file def store_dir "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}" end version :thumb do process :resize_to_limit =&gt; [200, 200] end end </code></pre> <p><strong>apps/views/images/show.html.erb</strong><br> Below, we can see that images can be rendered without issue, as this is a view for their own respective controller.</p> <pre><code>&lt;p&gt; &lt;strong&gt;Title:&lt;/strong&gt; &lt;%= @image.title %&gt; &lt;/p&gt; &lt;p&gt; &lt;strong&gt;Description:&lt;/strong&gt; &lt;%= @image.description %&gt; &lt;/p&gt; &lt;p&gt; &lt;strong&gt;Image:&lt;/strong&gt; &lt;%= image_tag @image.image_url.to_s %&gt; &lt;/p&gt; </code></pre> <p><strong>/apps/views/galleries/show.html.erb</strong><br> This is where everything gets tricky. First off, no matter what I change within the images div, everything within it seems to come up blank regardless. I've tried changing the "for image in @gallery.images" bit several times, but to no avail.</p> <pre><code>&lt;div id="images"&gt; &lt;% for image in @gallery.images %&gt; &lt;div class="image"&gt; &lt;%= image_tag image.image_url(:thumb) %&gt; &lt;%= image.description %&gt; &lt;div class="name"&gt;&lt;%= image.title %&gt;&lt;/div&gt; &lt;div class="actions"&gt; &lt;%= link_to "edit", edit_image_path(image) %&gt; | &lt;%= link_to "remove", image, :confirm =&gt; 'Are you sure?', :method =&gt; :delete %&gt; &lt;/div&gt; &lt;/div&gt; &lt;% end %&gt; &lt;div class="clear"&gt;&lt;/div&gt; &lt;/div&gt; &lt;p&gt; &lt;%= link_to "Add a Painting", new_image_path(:gallery_id =&gt; @gallery) %&gt; | &lt;%= link_to "Remove Gallery", @gallery, :confirm =&gt; 'Are you sure?', :method =&gt; :delete %&gt; | &lt;%= link_to "View Galleries", galleries_path %&gt; &lt;/p&gt; </code></pre>
