Deprecated Plugin

Tells you what techniques you are using that are out of fashion with the current Rails API.

This is not an endorsement by the Rails core team or a guarantee that your code will work correctly. It just tries to identify common problems.

Install as a Rails plugin:

./script/plugin install http://topfunky.net/svn/plugins/deprecated

Run the rake task:

rake deprecated

Messages will be printed to the screen:

--> @flash
  !! Use flash[] instead !!
  .........................
helpers/user_helper.rb:      notice = @flash[:notice]

--> @params
  !! Use params[] instead !!
  ..........................
views/articles/_search.rhtml:  text_field_tag('search_text', @params[:search_text])

--> @session
  !! Use session[] instead !!
  ...........................
controllers/user_controller.rb:    User.find(@session[:user_id])

--> component
  !! Use of components are frowned upon !!
  ........................................
helpers/articles_helper.rb:      render_component  :layout => false, 

--> find_all
  !! Use find(:all) instead !!
  ............................
controllers/articles_controller.rb:      @articles = Article.find_all

--> find_first
  !! Use find(:first) instead !!
  ..............................
controllers/articles_controller.rb:    @article = Article.find_first

--> paginate
  !! The default paginator is slow. Writing your own may be faster !!
  ...................................................................
controllers/articles_controller.rb:    @article_pages, @articles = paginate :articles, :order => 'created_at DESC'

TODO

• Rewrite in pure Ruby (currently requires grep)
• Updated for other deprecated items
• Tighten searches to be more specific
