Generate a list of Rails controllers and methods

rubp (john) — Sat, 17 Nov 2007 22:16:11 GMT

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

  Object.const_set('RAILS_DEFAULT_LOGGER', Logger.new(SDTOUT))

readable object output in Rails breakpointer

jeffmcdonald (Jeff McDonald) — Mon, 12 Dec 2005 06:46:39 GMT

breakpointer/console shows straight variable output as one long munge. Console can simply run .to_yaml to organize, breakpointer requires:



>> client.puts @object.to_yaml

script/console reload models

rtomayko (Ryan Tomayko) — Wed, 12 Oct 2005 01:48:00 GMT



$ ./script.console

Loading development environment...

>> [do stuff / modify models]

>> Dispatcher.reset_application!

Picked this up from...

http://habtm.com/articles/2005/10/04/script-console-reload-models

... which would have been fine but the site is completely unusable, opting for cool drag-and-drop over the ability to copy and paste. Bad.
