Rails2.3.10でrender_componentを使う
Rails2.3.10でrender_componentを使いたい。こちらには下記のように書いてある。
render_component goes from “deprecated” to “nonexistent” in Rails 2.3. If you still need it, you can install the render_component plugin.
install
% script/plugin install git://github.com/rails/render_component.git
サーバを起動するとメソッドがないと言われる

lackac/render_component が良いという噂
こちらによると、下記のところから持って来るといいよと書いてある。
% git://github.com/lackac/render_component.git
やってみる。さっきinstallした、render_componentは削除する。
% rm -fr vendor/plugins/render_component/ % script/plugin install git://github.com/lackac/render_component.git fatal: remote error: Could not find Repository lackac/render_component
http://github.com/lackac/render_component/tree/master が 404 だし・・・。
lib/components.rb を少しいじれば良いという噂
こちらによると、lib/components.rb の 13行目の :set_session_options を :session= にすれば良いとと書いてある。
# install % script/plugin install git://github.com/rails/render_component.git # 確認 % sed -e "s/:set_session_options/:session=/g" vendor/plugins/render_component/lib/components.rb | diff -u vendor/plugins/render_component/lib/components.rb - # 変更 % sed -i "s/:set_session_options/:session=/g" vendor/plugins/render_component/lib/components.rb # 確認 % head -n 20 vendor/plugins/render_component/lib/components.rb
別のエラーがでた・・・。

こちらがソース。やってみる。さっきinstallした、render_componentは削除する。

この噂で動いた。

2011/06/09 追記：「render_component と flash」について
Rails2.3にrender_componentを導入すると、Flashが使えなくなる問題があります。-http://railsforum.com/viewtopic.php?id=34367
下記のように修正すれば、Flashが使えるようになります。

しかし、コンポーネント機能は Rails2.0 で非推奨となり、Rails2.3 でサポートから外れました。render_component は Rails2.3 で plugin 化しました。このように、コンポーネント機能はrailsから離れつつありますので、2.3以降は、render_component自体も使わない方が良いかも知れませんね。
