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:
