def collection_select(attribute, collection, value_method, text_method, options={}, html_options={})
  if value_method.respond_to?(:call) || text_method.respond_to?(:call)
    collection = collection.map do |item|
      value = value_for_collection(item, value_method)
      text  = value_for_collection(item, text_method)
      [value, text]

#original_collection_select ⇒ Object

Override default Rails collection_select helper to handle lambdas/procs in text and value methods, so it works the same way as collection_radio and collection_check_boxes in SimpleForm. If none of text/value methods is a callable object, then it just delegates back to original collection select.
