Using date in Rails

richard — Thu, 27 Oct 2011 03:49:52 +0000

<%
Time.now.utc.to_s(:db) # 2011-01-01 01:01:01
Time.now.utc.strftime("%Y%m%d") # 2011-01-01 by UTC
Date.today.year.to_s + "07".to_s  # 201107 by Timezone
Date.today.month.to_s  # 10 by Timezone
Time.now.utc.strftime("%Y").to_s + sprintf('%02d', limit_month).to_s # 201107
# Yes, below code return true
(Date.today.year.to_s + "07".to_s) < (Date.today.year.to_s + "09".to_s)

if ( 1 ) ... end # is true
if ( 0 ) ... end # is TRUE

Using raw SQL in Rails

richard — Tue, 25 Oct 2011 03:01:05 +0000

Executing raw SQL

my_model.connection.execute('...')

from http://www.rabbitcreative.com/2007/06/08/executing-raw-sql-in-rails/

Get rows

<%
  @items = my_model.find_by_sql(["
    SELECT * FROM items WHERE 1 ORDER BY id DESC LIMIT 0, 10
  "]);
%>

<% for item in @items %>
  <%= item.user.id %>
<% end %>

Get row

<%
  @items = my_model.find_by_sql(["
    SELECT * FROM items WHERE 1 ORDER BY id DESC LIMIT 0, 10
  "]).first;
%>

<%= item.user.id %>

Using Cookie

richard — Sat, 22 Oct 2011 04:48:08 +0000

in PHP

Environment

define('COOKIE_NAME', 'my_cookie');
define('COOKIE_PATH', '/');
define('COOKIE_DOMAIN', 'www.my_site.com'); // or .my_site.com. Share cookies with sub domains.

$expiration = time() + 172800; // 2 days
$cookie = 'Hello Cookie!';

Set

setcookie(COOKIE_NAME, $cookie, $expiration, COOKIE_PATH, COOKIE_DOMAIN);

Get

$cookie = empty($_COOKIE[COOKIE_NAME]) ? $_COOKIE[COOKIE_NAME] : null;

Clear

setcookie(COOKIE_NAME, ' ', time() - 31536000, COOKIE_PATH, COOKIE_DOMAIN);

inspired from WordPress source code.
