How do I use my validator in the plugin?

Hooray, it worked

code in plugin.rb

def forum_require(path)
  require Rails.root.join('plugins', 'forum', 'app', path).to_s
end

after_initialize do

  forum_require 'lib/ldap_setting_validator'
//code
end

ldap_setting_validator.rb → path → myplugin/app/lib/ldap_setting_validator.rb

thanks for the example → babble/plugin.rb at master · gdpelican/babble · GitHub
