Routes

小心地使用 Match（Rails 3 已实现）

Rails 3 提供了 match 方法供我们自定义 routes，然而我们要小心使用它以避免“跨站脚本攻击”（XSS Attack）。比如像这样的 routes：

注：（r3 代表 Rails 3，r4 代表 Rails 4）

# routes.rb

#Model 

@user.should have(1).error_on(:username) # Checks whether there is an error in username 
@user.errors[:username].should include("can't be blank")  # check for the error message 

#Rendering
response.should render_template(:index)

#Redirecting 
response.should redirect_to(movies_path)

// Settings in here override those in "Default/Preferences.sublime-settings", and
// are overridden in turn by file type specific settings.
{
	"color_scheme": "Packages/Color Scheme - Default/Monokai.tmTheme",
	"font_face": "Monaco",
	"font_size": 14,
	// Valid options are "no_bold", "no_italic", "no_antialias", "gray_antialias",
	// "subpixel_antialias" and "no_round" (OS X only)
	// 字体选项：no_bold 不显示粗体字，no_italic 不显示斜体字，no_antialias 和 no_antialias 关闭反锯齿
	// subpixel_antialias 和 no_round 是 OS X 系统独有的

# 30 minutes Lisp in Ruby
# Hong Minhee <http://dahlia.kr/>
#
# This Lisp implementation does not provide a s-expression reader.
# Instead, it uses Ruby syntax like following code:
#
#     [:def, :factorial,
#       [:lambda, [:n],
#         [:if, [:"=", :n, 1],
#               1,

source/_includes/custom/head.html中添加js代码:

<script>
  function addBlankTargetForLinks () {
    $('a[href^="http"]').each(function(){
        $(this).attr('target', '_blank');
    });
  }

  $(document).bind('DOMNodeInserted', function(event) {

备份：

备份整个数据库
exp 用户名/密码@连接的远程计算机 IP/ 要备份的远程数据库名称 file= 文件路径 
exp hom/my_pwd@192.168.5.14/qa file=d:\aa1.dmp  

备份指定数据库表
exp Intfocus/my_pwd@192.168.0.200/orcl file=d:\DOG_TOTAL_BI.DMP tables=(dog_totle_bi)

导入指定数据库表（若表结构已经存在只导入数据）
