Call method dynamically on active record association

Hey all,

I have this in view:

  - if site_action_enabled?(:site_flag_enabled, Site)

And I have this in application controller:

def site_action_enabled?(operation, resource)
if resource.is_a?(Class) && resource == Site
return operation
return false

helper_method :site_action_enabled?

It gives me error:

undefined method `call’ for

If I use something like send:

  return operation

It does not call the site_flag_enabled instance method, which returns
true or false (site_flag_enabled is a field in database for sites
table of tinyint type)

thanks for response
