def _get_user_for(field_name) #:nodoc:
  if @record[field_name]
    u = DcUser.find(@record[field_name])
    return u ? u.name : @record[field_name]
  end
#  nil
end

#dc_actions_for_form ⇒ Object

Creates actions div for edit form.

Displaying readonly form turned out to be challenge. For now when readonly parameter has value 2, back link will force readonly form. Value 1 or not set will result in normal link.
