  1. POWhere do the temp files go when using MiniMagick in a Ruby on Rails app?
    text
    copied!<p>I'm using MiniMagick to perform some image resizing on images uploaded through a multi-part form. I need to generate a few different types of images from the originally uploaded file. Here's the code that's performing the image processing:</p> <pre><code>// Generates a thumbnail image mm = MiniMagick::Image.open(Rails.root.join('public', 'uploads', new_url)) mm.resize(thumbnail_dimensions.join("x")) mm.write(Rails.root.join('public', 'uploads', "t_"+new_url)) // Generates cropped version mm_copy = MiniMagick::Image.open(Rails.root.join('public', 'uploads', new_url)) mm_copy.crop('200x200') mm_copy.write(Rails.root.join('public', 'uploads', "c_"+new_url)) </code></pre> <p><code>new_url</code> is the path to the image in the <code>public</code> folder. The thumbnail routine works perfectly. When the app goes to start processing the cropped version, that is where things start breaking and I can't for the life of me figure it out. I receive the following error when from this code:</p> <pre><code>No such file or directory - /tmp/mini_magick20110627-10055-2dimyl-0.jpg </code></pre> <p>I read some stuff about possible race conditions with the garbage collector in Rails but I wasn't able to resolve the issue. I tried this from the console as well and can create MiniMagick instances but receive the <code>No such file</code> error there as well. At this point, I have no idea where to go so I'm hoping someone here has some helpful suggestions. Thanks for your help!</p> <p><strong>Details</strong>:</p> <ul> <li>OS: Ubuntu (Lucid Lynx)</li> <li>Rails Version: 3.0.7</li> <li>Ruby Version: 1.8.7</li> <li>MiniMagick Version: 3.3</li> </ul>
