Rails 4 appears to log SQL queries in the console in development by default. If it doesn't, I can't figure out why it is for me.

Kaminari ajax pager
If you switch to kaminari,
http://railscasts.com/episodes/254-pagination-with-kaminari
...the lines added to application.js become redundant when you implement the pager like in this demo project:

HenrikJoreteg / JS Util solution using underscore.js
Created October 22, 2010 21:20
Rather than creating some other util global, just extend underscore.js with any additional methods you want.
// If you don't use underscore.js, use it (http://documentcloud.github.com/underscore/)
// Then, use underscore's mixin method to extend it with all your other utility methods
// like so:
_.mixin({
escapeHtml: function () {
return this.replace(/&/g,'&amp;')
.replace(/>/g,'&gt;')
.replace(/</g,'&lt;')
.replace(/"/g,'&quot;')
.replace(/'/g,'&#39;');

将不同大小的img放在固定大小的div中; 要求img不能被拉伸覆盖、要水平居中放置在中间; 如果图片高度超出容器，则以高度为基准确定宽度，反之亦然； img不固定大小设置为inline，外层用line-height和text-align:center确定水平垂直居中；
