裝Attachment_fu

Sun, 18 Jan 2009 15:56:31 GMT

裝attachment_fu畀Rails用好易。

首先裝咗ImageScience先。
裝法：
$ sudo gem install image_science

跟住作去Rails嗰個App嘅目錄，裝attachment_fu
$ script/plugin install http://svn.techno-weenie.net/projects/plugins/attachment_fu/

之後，起個class table畀啲file

class CreateUploadFile < ActiveRecord::Migration
  def self.up
    create_table :upload_files do |t|
      # 所有都用
      t.string  :content_type
      t.string  :filename    
      t.integer :size
      # image 用
      t.integer :width
      t.integer :height
      # thumbnail 用
      t.string  :thumbnail 
      t.integer :parent_id
      # 如果揀用database儲file
      t.references :db_file
    end
  end
  def self.down
    drop_table :upload_files
  end
end

#如果用database儲
def CreateDbFiles < ActiveRecord::Migration
  def self.up
    create_table :db_files do
      t.binary :data
    end
  end
  def self.down
    drop_table :db_files
  end
end

係咁樣，搞掂。

個class UploadFile入便，
加has attachment同佢一堆option搞掂。

跟住係整view或controller控制。

Rails format

Thu, 15 Jan 2009 09:16:43 GMT

Rails要回返啲嘢畀client之前，會check返有client有send啲乜Accept過來。

畀個例
首先要/objects/1.html
Client交呢個Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Rails就會搵html個項
respond_to do |format|
format.html ...
format.xml ...
format.jpg ...
format.all ...
end

對個對法係來自個type有無做Mime.register
Mime.register其中一行，有mime type係text/html，extension係html，symbol係:html
咁對html, 搵有:html，咁就夾format.html

咁Rails交出之時，就會對下Accept有無:html嘅mime type，對到有text/html，咁就send出去。

如果client無話可以Accept，就會話406 Not Accepted。

之不過Rails唔夠聰明，就算*都要指明，唔係佢唔識handle㗎。不過佢留有*/*來map去:all，咁format.all就會handle得到。

Rails migration 整數改咗rule

Wed, 07 Jan 2009 10:08:23 GMT

家下Rails class Migration::Base之下

以前咁寫
t.integer :amount
預設係MySQL int(11)，係幾個數字。
家下Rails改咗用byte計，咁:limit個數字就唔同咗意思。
1 byte等於MySQL tinyint
2 byte係smallint
3 byte係mediumint
4 byte係int(11)
5..8 byte係bigint

咁為咗同舊時一樣nil同11作同等同家下4，即係default都係4
大過8,　rails migration會鬧你。

Debian用exim4寄信

Wed, 07 Jan 2009 09:48:24 GMT

Debian預設係用exim4收信寄信。

如果唔使收信，而自己部機做埋SMTP server，直接寄信出去。

可以行
$ dpkg-reconfigure exim4-config
Split configuration into small files? Yes 同 No都得。
揀internet site; mail is sent and received directly using SMTP。
system mail name做localhost.localnet。
ip收信。127.0.0.1。
destination吉咗。
relay mail兩次都吉咗。
Keep number of DNS-queries minimal做No。
揀mbox format in /var/mail/。

搞掂。

Ruby時間

Wed, 07 Jan 2009 05:54:14 GMT

Ruby時間用Time class比較好.

n = Time.now # => Wed Jan 07 14:48:20 +0800 2009
n.to_s(:db) # => "2009-01-07 14:48:20"
年
n.year # => 2009
月
n.mon # => 1
n.month # => 1
日
n.day # => 7
n.mday # => 7
時
n.hour # => 14
分
n.min # => 48
秒
n.sec # => 20
禮拜
n.wday # => 3

rails升降一個version

Wed, 07 Jan 2009 04:33:27 GMT

之前rails改咗schema migration嘅方式，由排次序變咗記時間。

database上原本有個schema_info嘅table，記住最新version。家下table變成schema_migration，記住一堆行咗migration嘅version。

咁可以個別up同down，唔會depend on之前嗰啲。
$ rake db:migrate:down VERSION=20090106022903
$ rake db:migrate:up VERSION=20090106022903
up就加一條入table，down就減一條。

down完自己順手delete埋個migration file，就一了百了。

ruby同crontab

Wed, 07 Jan 2009 01:45:02 GMT

Ruby有個叫cronedit嘅rubygems，可以用來行cron。佢個cron係user嘅cron，唔會干擾system個cron。

佢做嘅嘢，就係改user個crontab，即
$ crontab
做嘅嘢。

咁用之前，咁緊係要裝cronedit。
$ sudo gem update
$ sudo gem install cronedit

寫個Ruby程式
require 'rubygems'
require 'cronedit'

include CronEdit
Crontab.Add 'task_a' { :command => 'finger -l' }
如果定時間，喺每日晨咁早搭正三點鐘，
Crontab.Add 'task_hourly' { :minute => 0, :hour => 3, :command => 'finger -l' }
如果唔用hash，直接用crontab格式一樣得，
Crontab.Add 'task_specific' "10,40 0-23/2 * * * finger -l"

如果唔要某個task，畀個名Remove就得
Crontab.Remove 'task_specific'
