themes_controller.rb

用ruby on rails写的一个博客程序,还不错..ruby on rails的确是个好框架

class Admin::ThemesController < Admin::BaseController

  def index
    @themes = Theme.find_all
    @themes.each do |theme|
      theme.description_html = TextFilter.filter_text(this_blog, theme.description, nil, [:markdown,:smartypants])
    end
    @active = this_blog.current_theme
  end

  def preview
    send_file "#{Theme.themes_root}/#{params[:theme]}/preview.png", :type => 'image/png', :disposition => 'inline', :stream => false
  end

  def switchto
    this_blog.theme = params[:theme]
    this_blog.save
    redirect_to :action => 'index'
  end
end
