RoR的IDE就用gedit吧
參考：
https://github.com/gmate/gmate
sudo add-apt-repository ppa:ubuntu-on-rails/ppa
sudo apt-get update
sudo apt-get install gedit-gmate
cd Downloads/
wget http://dl.dropbox.com/u/5986982/gmate.sh
chmod +x gmate.sh
sh gmate.sh
sudo apt-get install git-core
git clone git://github.com/gmate/gmate.git
cd gmate
sh install.sh
vim /etc/mime.types
text/x-ruby-source rhtml html.erb erb
text/x-eruby rjs
text/x-yaml yml yaml
sudo apt-get install gedit-plugins
gem install rails-footnotes
GIT clone
1) git clone git://github.com/MadsBuus/gedit-snapopen-plugin.git
2) create a symlink:
mkdir -p ~/.gnome2/gedit/
cd ~/.gnome2/gedit/
ln -s [path/to/clone] plugins

Ruby for Rails 學習心得01
Ruby for Rails : Rails開發者必備的Ruby學習手冊 –> 大推
Ruby code 怎麼去寫讀local檔和建立新文字檔，修改文字檔:
1. read file
a = File.read(“filename")
2. create file
a = File.new(“filename", “w")
a.close
3. write to file
a = File.new(“filename", “w")
a.puts b
a.close
*** ruby tool 實用工具(大推):
1. ruby -r debug filename (debug)
2. ruby -r profile filename (check utilization)
*** what’s erb 什麼是 .erb
1. 在html檔案裡面，置入Ruby code
2. 將RoR模子->操作->呈現，就是最後一個呈現網頁結果，通常會是或是
3. 執行erb和執行rb不一樣，執行erb要用 “erb filename"
*** 所謂的MVC結構
串起M-V-C，一定是Rails:
/usr/local/rvm/gems/ruby-1.9.2-p180/gems/rails-3.0.1
M的解釋：
Model (ActiveRecord): /usr/local/rvm/gems/ruby-1.9.2-p180/gems/activerecord-2.3.2/
C的解釋：
Control (ActionController): /usr/local/rvm/gems/ruby-1.9.2-p180/gems/actionpack-3.0.1/lib/action_controller
V的解釋：
View (ActionView): /usr/local/rvm/gems/ruby-1.9.2-p180/gems/actionpack-3.0.1/lib/action_view

Day 12 — Ruby on Rails 終章
快被這段搞到費屬人，最後面除了看screencast之外，book一定要喵到，否則除蟲除不完>_<：
class Micropost 'microposts.created_at DESC'
# Return microposts from the users being followed by the given user.
scope :from_users_followed_by, lambda { |user| followed_by(user) }
private
# Return an SQL condition for users followed by the given user.
# We include the user's own id as well.
def self.followed_by(user)
following_ids = user.following_ids
where("user_id IN (#{following_ids}) OR user_id = :user_id",
{ :user_id => user })
end
end
總算全部搞定 ︿︿！成績單在此：http://falling-winter-693.heroku.com/
