or in other words

:link\_to model.name, :controller =\> ‘controllername’, :action =\>  
‘create\_by’

controller functions dont accept arguments. so calling your function  
like link\_to \_created\_by ‘name’ is wrong for several reasons:

1. you misspelled your function name \_create\_by instead of create\_by
2. you passed name as an argument (you should use params)
