Instance Method Details

#get_resource(arg) ⇒ Object

If required, overwrite this method to return a resource object identified by the argument.

This might be necessary if you change the to_param method of an ActiveRecord class.

class Course < ActiveRecord::Base
  ...
  # each course has a unique name --> make better urls
  def to_param
    name
  end

  def self.get_resource(name)
    find_by_name(name)
  end

Raises:

  • (NoMethodError)
