Reference on link_to here:
http://api.rubyonrails.org/classes/ActionView/Helpers/UrlHelper.html#method-i-link_to
:method is used for specifying HTTP method such as POST, GET, etc.
The parameter that you are passing (method_to_run) is not a valid value for
:method.
I suggest you define a controller and invoke one of its methods through the
link.
Example:
link_to "Feature", :controller => "mycontroller", :action => "method_to_run"
