module ActionView
module Helpers
module RecordTagHelper
# Produces a wrapper DIV element with id and class parameters that
# relate to the specified Active Record object. Usage example:
#
# <%= div_for(@person, :class => "foo") do %>
# <%=h @person.name %>
# <% end %>
#
# produces:
#
# <div id="person_123" class="person foo"> Joe Bloggs </div>
#
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 %>
# <td><%=h @person.first_name %></td>
# <td><%=h @person.last_name %></td>
# <% end %>
#
# would produce the following HTML (assuming @person is an instance of
# a Person object, with an id value of 123):
#
# <tr id="person_123" class="person">....</tr>
#
# If you require the HTML id attribute to have a prefix, you can specify it:
#
# <%= content_tag_for(:tr, @person, :foo) do %> ...
#
# produces:
#
# <tr id="foo_person_123" class="person">...
#
# content_tag_for also accepts a hash of options, which will be converted to
# additional HTML attributes. If you specify a <tt>:class</tt> value, it will be combined
# with the default class name for your object. For example:
#
# <%= content_tag_for(:li, @person, :class => "bar") %>...
#
# produces:
#
# <li id="person_123" class="person bar">...
#
def content_tag_for(tag_name, record, *args, &block)
prefix = args.first.is_a?(Hash) ? nil : args.shift
options = args.extract_options!
options.merge!({ :class => "#{dom_class(record, prefix)} #{options[:class]}".strip, :id => dom_id(record, prefix) })
content_tag(tag_name, options, &block)
