How to pass model names?

The scenario is that i have written a function in application_hepler.rb as like..

def all_record_ids(model_name)   all_records = model_name.all.find_all {     >record> record.status == "ACTIVE"   } end

I am calling this function as like [ all_record_ids("Employee") ] but instead of getting result i am getting error as [ "undefined method `all' for "Employee":String" ]

So what is wrong here .. ? Can you guys light me up some direction ?

It's one of the Inflector methods... well worth being familiar with them: http://api.rubyonrails.org/classes/Inflector.html
