*SVN*
* Fixed a problem with Flash.now
* Fixed stringification on all assigned hashes. The sacrifice is that assigns[:person] won't work in testing. Instead assigns["person"] or assigns(:person) must be used. In other words, the keys of assigns stay strings but we've added a method-based accessor to appease the need for symbols.
* Fixed that rendering a template would require a connection to the database #1146

module FormOptionsHelper
include ERB::Util
# Create a select tag and a series of contained option tags for the provided object and method.
# The option currently held by the object will be selected, provided that the object is available.
# See options_for_select for the required format of the choices parameter.
#
# Example with @post.person_id => 1:
# select("post", "person_id", Person.find_all.collect {|p| [ p.name, p.id ] }, { :include_blank => true })
#
# could become:
#
# <select name="post[person_id">
# <option></option>
# <option value="1" selected="selected">David</option>
# <option value="2">Sam</option>
# <option value="3">Tobias</option>
# </select>
#
# This can be used to provide a default set of options in the standard way: before rendering the create form, a
# new model instance is assigned the default options and bound to @model_name. Usually this model is not saved
