    <p><a href="http://horserumble.com/creating-facebook-events-with-koala#comment" rel="nofollow">I followed the following blogpost</a> to figure out how to create Facebook events remotely using my app. I've been having problems loading the images from my app, however, because I do not have images stored locally on my app, they are stored in AWS. </p> <blockquote> <pre><code> @graph = Koala::Facebook::GraphAPI.new(@token) picture = Koala::UploadableIO.new(@event.photo.url(:small)) params = { :picture =&gt; picture, :name =&gt; 'Event name', :description =&gt; 'Event descriptio :start_time =&gt; datetime, } </code></pre> </blockquote> <p>is the following code I am currently using to send pictures to Facebook when Facebook events are created on my app. The problem is, however, that Rails is throwing the error: No such file or directory - <a href="http://s3.amazonaws.com/ColumbiaEventsApp/photos/21/small.jpeg?1312521889" rel="nofollow">http://s3.amazonaws.com/ColumbiaEventsApp/photos/21/small.jpeg?1312521889</a>. </p> <p>Does anybody who's more experienced with Rails development know if there is a way for me to treat a URL like a path to a file? The UploadableIO class expects a path to a file, and I'm struggling to figure out if there's a way in Ruby to treat URL's like filepaths. The way that photos stored on the app can be loaded to Facebook is as follows: </p> <blockquote> <p>picture = Koala::UploadableIO.new(File.open("PATH TO YOUR EVENT IMAGE"))</p> </blockquote> <p>if that helps.</p> <p>I appreciate any new insights into this issue. </p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
