You can override the #protect? method in your controller to only protect certain actions:\r\n\
\r\n # don't protect the login and the about method\r\n def protect?(action)\r\n if ['login', 'about'].include?(action)\r\n return false\r\n else\r\n return true\r\n end\r\n end\r\n\
\r\n\
You can also override #authorized? in your controller to restrict the actions based on the user:\r\n\
\r\n # only allow nonbobs\r\n def authorized?(user)\r\n user.login != \"bob\" \r\n end"
