Generate a list of Rails controllers and methods

This code goes over the App/controllers directory and extracts a list
of all controllers and their methods.

use this script from rails console.

I have used this script to generate a migration file with default authorization roles & rights.



controllers = Dir.new("#{RAILS_ROOT}/app/controllers").entries

controllers.each do |controller|

 if controller =~ /_controller/ 

  cont = controller.camelize.gsub(".rb","")

  puts cont

  (eval("#{cont}.new.methods") - 

    ApplicationController.methods - 

    Object.methods -  

    ApplicationController.new.methods).sort.each {|met| 

       puts "\t#{met}"

    }

end



end

to use it to create a Right object I used the following adjustments:



controllers.each do |controller|

    if controller =~ /_controller/ 

    name = controller.camelize.gsub(".rb","")

     (eval("#{name}.new.methods") - 

       Object.methods -  

       ApplicationController.new.methods).sort.each {|met| 

          name_short = name.gsub("Controller","").downcase

          #it is possible to call the create directly from this script

          #I wanted to review and revise the names. 

          puts "#{met}_#{name_short}=Right.create(:name=>\"#{met} #{name_short}\",

                                                  :controller=>\"#{name_short}\",

                                                  :action=>\"#{met}\")"}

  end

  end
