    copied!<p>I'm trying to figure out how to properly setup <a href="https://github.com/jnicklas/carrierwave" rel="nofollow noreferrer">Carrierwave</a> to be able to handle a file being sent via <a href="https://github.com/valums/file-uploader" rel="nofollow noreferrer">File Uploader</a>.</p> <h2>File Uploader</h2> <p>I've attached <code>fileuploader.js</code> and <code>fileuploader.css</code> to my asset pipeline (rails 3.2.0) and have the following html:</p> <pre><code>&lt;div id="file-uploader"&gt; &lt;noscript&gt; &lt;p&gt;Please enable JavaScript to use file uploader.&lt;/p&gt; &lt;!-- or put a simple form for upload here --&gt; &lt;/noscript&gt; &lt;/div&gt; </code></pre> <p>And javascript:</p> <pre><code>$(document).ready(function(){ var uploader = new qq.FileUploader({ // pass the dom node (ex. $(selector)[0] for jQuery users) element: $('#file-uploader')[0], // path to server-side upload script action: '/photos', debug: true, params: { authenticity_token: "&lt;%= form_authenticity_token.to_s %&gt;" }, onComplete: function(id, fileName, responseJSON){ alert(responseJSON.toString()); } }); }); </code></pre> <p>When I select a file it kicks off the script and my application gets called. That is what I don't know how to handle.</p> <h2>Carrierwave</h2> <p>I have a <code>Photo</code> model which has <code>mount_uploader :image, ImageUploader</code>. Therefore in <code>PhotoController</code> I have:</p> <pre><code>def create io = AppSpecificStringIO.new(request.raw_post,params[:qqfile]) @photo = Photo.new(:image =&gt; io) if @photo.save respond_to do |format| format.js { render :josn =&gt; @photo.to_json(:methods =&gt; :success, :only =&gt; [:id, :image]) } end else respond_to do |format| format.js { render :josn =&gt; {:success=&gt;false} } end end end </code></pre> <p>The param only has <code>qqfile</code> which is the file name. I found out that <code>request.raw_post</code> has the data for the image. But I don't know what format it is (is it 64Bit or not). I've been trying to find any resource I could on the subject and trying out anything. One <a href="https://github.com/jnicklas/carrierwave/wiki/How-to%3A-Upload-from-a-string-in-Rails-3" rel="nofollow noreferrer">source</a> on Carrierwave's wiki suggested to use a AppSpecificStringIO class.</p> <pre><code>class AppSpecificStringIO &lt; StringIO attr_accessor :filepath def initialize(*args) super(*args[1..-1]) @filepath = args[0] end def original_filename File.basename(filepath) end end </code></pre> <p>On File Uploader's wiki there is a <a href="https://github.com/valums/file-uploader/wiki/Rails-%2B-CarrierWave" rel="nofollow noreferrer">suggestion</a> for CarrierWave, but I can't figure anything out there either. <code>CarrierwaveStringIO</code> doesn't exist as far as I can see.</p> <p>I just want to get an ajax solution to uploading images to Carrierwave. Thank you to anyone who can help me.</p> <h3>Other links for reference:</h3> <ul> <li><a href="https://stackoverflow.com/questions/7622404/use-base64-image-with-carrierwave">base64 image with Carrierwave - SO Question</a> </li> <li><a href="https://github.com/valums/file-uploader/tree/master/server" rel="nofollow noreferrer">File uploader's notes on server side info</a> - looks like I need to handle two ways to get the file.</li> </ul>
