javascript - express, mongoose passing param from 1 app.get to another -


my problem cannot quite figure out how "name" parameter before run second app.get.. first (app.get /) lets me choose between collections, , pass "name" param second app can req.params.name within second app.get...

problem need param before second app.get cuz need define schema , "compile" model, can done once. works when click once, "cannot owerwrite model, compiled" error when again. bypassed problem opening new connection everytime load second app.get (not know).

so if knows how "name" param (the thing im passing req.param second app.get, before actual second app.get fires up, thankful)

my code: (started learning node 2 days ago, alongside express , mongoose, not mention javascript sp go easy on me :p)

var express = require('express') ,routes = require('./routes') ,user = require('./routes/user') ,http = require('http') ,path = require('path') ,mongoose = require("mongoose");  var app = express();  // environments app.set('port', process.env.port || 3005); app.set('views', __dirname + '/views'); app.set('view engine', 'jade'); app.use(express.favicon()); app.use(express.logger('dev')); app.use(express.bodyparser()); app.use(express.methodoverride()); app.use(app.router); app.use(express.static(path.join(__dirname, 'public')));  // development if ('development' == app.get('env')) {   app.use(express.errorhandler()); }  conn = mongoose.createconnection("mongodb://10.42.1.31/dominik");  app.get ("/", function(req, res) {     conn.db.collectionnames(function (err, docs) {       res.render("collections", {names:docs});   }); });  app.get("/collections/:name", function (req,res) {  conn = mongoose.createconnection("mongodb://10.42.1.31/dominik");   var collname = req.params.name;   collname = collname.charat(0).touppercase()+collname.slice(1);   collname = collname.substring(0, collname.length-1);   var schema = new mongoose.schema({});   var mymodel= conn.model(collname, schema);   mymodel.find({},function(err, docs) {    res.json("documents",docs);   }); });  http.createserver(app).listen(app.get('port'), function(){   console.log('express server listening on port ' + app.get('port')); });

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
