      content: null,
      run: function(req, res, next) {
          model.setDB(req.db);
          var self = this;
          req.body = _.omit(req.body, '__proto__');
         res.header("Access-Control-Allow-Origin", "*");
    res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
      res.writeHead(200, { 'Content-Type': 'application/json' }); 
        res.end(JSON.stringify(req.body));
  
          /*this.getContent(function() {
          //  var v = new View(res, 'place');
          res.setHeader('Content-Type', 'application/json');
      res.send(JSON.stringify(self.content));
