Constants

DEFAULT_PARTIAL = %{ <div> <div class="errorExplanation" id="errorExplanation"> <h2><%= pluralize_word(errors.size, "error") %> occured.</h2> <ul> <% for error in errors %> <li><%= error %></li> <% end %> </ul> </div> </div> } unless Mack::ViewHelpers::DataMapperHelpers.const_defined?("DEFAULT_PARTIAL")

Public Instance methods

error_messages_for(object_names = [], view_partial = nil)

Provides view level support for printing out all the errors associated with the models you tell it. The DEFAULT_PARTIAL constant provides a simple, default, set of HTML for displaying the errors. If you wish to change this HTML there are two simple ways of doing it. First if you have a partial named: app/views/application/_error_messages.html.erb, then it will use that default, and not DEFAULT_PARTIAL. The other option is to pass in a path to partial as the second argument and that partial will be rendered.
