title: Upload file on AppFog with NodeJS
body: <p>I created an NodeJS App using Express and I uploaded my App on AppFog, the only problem is that I have a file upload form in my App in order to upload some photos for the App (for my "Creation" table). It works in local but on AppFog it doesn't work, maybe AppFog have locked the upload files... I don't know exactly what am I supposed to do... My CHMOD directory is "0777".</p>
  
  <p>(sorry for my english, I come from Europe)</p>
  
  <p>My view:</p>
  
  <pre><code>  form.admin(action='/creations/save', method='post', enctype='multipart/form-data')
      div
        label(for='title') Title
        input(type='text', name='title', placeholder='Title...')
      div
        label(for='thumbnail') Thumbnail
        input(type='file', name='thumbnail')
      div
        label(for='moodboard') Moodboard
        input(type='file', name='moodboard')
      input(type='submit', value='Save')
      input(type='reset', value='Cancel')
  </code></pre>
  
  <p>My controller:</p>
  
  <pre><code>var saveFile = function(file, folder){
      var file_tmp = file.path;
      var file_name = file.name;
      var file_type = file.type;
      var file = './uploads/'+folder+'/'+file_name;
      console.log(file);
      fs.rename(file_tmp, file, function(err){
          if( err ) console.log(err);
      });
  }
  
  exports.save = function(req, res) {
      saveFile(req.files.thumbnail, 'thumbnails');
      saveFile(req.files.moodboard, 'moodboards');
      global.db.Creation.create({
          title: req.body.title,
          description: req.body.description,
          location: req.body.location,
          date: req.body.date,
          thumbnail: req.files.thumbnail.name,
          moodboard: req.files.moodboard.name
      }).success( function(creation){
          res.redirect('/glovebox');
      });
  }
  </code></pre>
