# def div_for(record, *args, &block) content_tag_for(:div, record, *args, &block) end # content_tag_for creates an HTML element with id and class parameters # that relate to the specified Active Record object. For example: # # <% content_tag_for(:tr, @person) do %> # <%=h @person.first_name %> # <%=h @person.last_name %> # <% end %> # # would produce the following HTML (assuming @person is an instance of # a Person object, with an id value of 123): # # .... # # If you require the HTML id attribute to have a prefix, you can specify it: # # <% content_tag_for(:tr, @person, :foo) do %> ... # # produces: # # ... # # content_tag_for also accepts a hash of options, which will be converted to # additional HTML attributes. If you specify a :class value, it will be combined # with the default class name for your object. For example: # # <% content_tag_for(:li, @person, :class => "bar") %>... # # produces: # #
