RubyGems is a sophisticated package manager for Ruby. This is a
basic help message containing pointers to more information.
Usage:
gem -h/--help
gem -v/--version
gem command [arguments...] [options...]
Examples:
gem install rake
gem list --local
gem build package.gemspec
gem help install
Further help:
gem help commands list all 'gem' commands
gem help examples show some examples of usage
gem help platforms show information about platforms
gem help <COMMAND> show help on COMMAND
(e.g. 'gem help install')
Further information:
http://rubygems.rubyforge.org
}
***gem コマンド一覧
>gem help commands
#openclose(show=実行結果){
GEM commands are:
build Build a gem from a gemspec
cert Manage RubyGems certificates and signing settings
check Check installed gems
cleanup Clean up old versions of installed gems in the local
repository
contents Display the contents of the installed gems
dependency Show the dependencies of an installed gem
environment Display information about the RubyGems environment
fetch Download a gem and place it in the current directory
generate_index Generates the index files for a gem server directory
help Provide help on the 'gem' command
install Install a gem into the local repository
list Display gems whose name starts with STRING
lock Generate a lockdown list of gems
mirror Mirror a gem repository
outdated Display all gems that need updates
pristine Restores installed gems to pristine condition from files
located in the gem cache
query Query gem information in local or remote repositories
rdoc Generates RDoc for pre-installed gems
search Display all gems whose name contains STRING
server Documentation and gem repository HTTP server
sources Manage the sources and cache file RubyGems uses to search
for gems
specification Display gem specification (in yaml)
stale List gems along with access times
uninstall Uninstall gems from the local repository
unpack Unpack an installed gem to the current directory
update Update the named gems (or all installed gems) in the local
repository
which Find the location of a library file you can require
For help on a particular command, use 'gem help COMMAND'.
Commands may be abbreviated, so long as they are unambiguous.
e.g. 'gem i rake' is short for 'gem install rake'.

***scaffoldの利用方法
>ruby script/generate scaffold -h
#openclose(show=実行結果){
Usage: script/generate scaffold ModelName [field:type, field:type]
Options:
--skip-timestamps Don't add timestamps to the migration file for this model
--skip-migration Don't generate a migration file for this model
--force-plural Forces the generation of a plural ModelName
Rails Info:
-v, --version Show the Rails version number and quit.
-h, --help Show this help message and quit.
General Options:
-p, --pretend Run but do not make any changes.
-f, --force Overwrite files that already exist.
-s, --skip Skip files that already exist.
-q, --quiet Suppress normal output.
-t, --backtrace Debugging: show backtrace on errors.
-c, --svn Modify files with subversion. (Note: svn must be in path)
-g, --git Modify files with git. (Note: git must be in path)
Description:
Scaffolds an entire resource, from model and migration to controller and
views, along with a full test suite. The resource is ready to use as a
starting point for your RESTful, resource-oriented application.
Pass the name of the model (in singular form), either CamelCased or
under_scored, as the first argument, and an optional list of attribute
pairs.
Attribute pairs are column_name:sql_type arguments specifying the
model's attributes. Timestamps are added by default, so you don't have to
specify them by hand as 'created_at:datetime updated_at:datetime'.
You don't have to think up every attribute up front, but it helps to
sketch out a few so you can start working with the resource immediately.
For example, 'scaffold post title:string body:text published:boolean'
gives you a model with those three attributes, a controller that handles
the create/show/update/destroy, forms to create and edit your posts, and
an index that lists them all, as well as a map.resources :posts
declaration in config/routes.rb.
If you want to remove all the generated files, run
'script/destroy scaffold ModelName'.
Examples:
`./script/generate scaffold post`
`./script/generate scaffold post title:string body:text published:boolean`
`./script/generate scaffold purchase order_id:integer amount:decimal`
}
**rake
Rubyのビルドツール(AntやMake等)
***rake オプション一覧
>rake -h
#openclose(show=実行結果){
rake [-f rakefile] ｛options｝ targets...
Options are ...
-C, --classic-namespace Put Task and FileTask in the top level namespace
-D, --describe [PATTERN] Describe the tasks (matching optional PATTERN), then exit.
-n, --dry-run Do a dry run without executing actions.
-e, --execute CODE Execute some Ruby code and exit.
-p, --execute-print CODE Execute some Ruby code, print the result, then exit.
-E, --execute-continue CODE Execute some Ruby code, then continue withnormal task processing.
-I, --libdir LIBDIR Include LIBDIR in the search path for required modules.
-P, --prereqs Display the tasks and dependencies, then exit.
-q, --quiet Do not log messages to standard output.
-f, --rakefile [FILE] Use FILE as the rakefile.
-R, --rakelibdir RAKELIBDIR Auto-import any .rake files in RAKELIBDIR.(default is 'rakelib')
--rakelib
-r, --require MODULE Require MODULE before executing rakefile.
--rules Trace the rules resolution.
-N, --no-search, --nosearch Do not search parent directories for the Rakefile.
-s, --silent Like --quiet, but also suppresses the 'in directory' announcement.
-g, --system Using system wide (global) rakefiles (usually '~/.rake/*.rake').
-G, --no-system, --nosystem Use standard project Rakefile search paths, ignore system wide rakefiles.
-T, --tasks [PATTERN] Display the tasks (matching optional PATTERN) with descriptions, then exit.
-t, --trace Turn on invoke/execute tracing, enable full backtrace.
-v, --verbose Log message to standard output.
-V, --version Display the program version.
-h, -H, --help Display this help message.

**マイグレーション
ＤＢのバージョン管理システム。
具体的には次のような仕組みです。
-db/migrateディレクトリ配下にdb/migrate/20080728204433_create_categories.rbのように、DBに対する変更内容が記述されたファイルを配置
-このとき、各ファイル名の先頭には「20080728204433」の部分のように、タイムスタンプに基づくバージョン情報が付く
-マイグレーションは現在のDBのバージョン情報を保持する。これにより、db/migration内のファイルのうち、どれがDBに反映されて、どれが反映されていないかが分かる
-「db:migrate」というrakeタスク（「make install」のようなバッチ処理をイメージすると分かりやすい）を実行して、未反映の変更をDBに反映させることができる（＝最新状態までバージョンアップ）
-バージョン情報を指定してrakeタスクを実行し、バージョンを任意のバージョンにバージョンアップ、バージョンダウンさせることもできる
