options_for_select($choices, $selected = null) X-Ref

Generate HTML option tags from a list of choices

Accepts an array of possible choices and returns a string of
option tags.  The value of each array element becomes the
visible text of an option, and the key of the element becomes
the value returned to the server.  For example:<br />
<samp>options_for_select(array('foo','bar'));</samp><br />
will return:<br />
<samp><option value="0">foo</option>\n</samp><br />
<samp><option value="1">bar</option></samp><br />

The optional second argument specifies the array key of an
option to be initially selected.

NOTE: Only the option tags are returned, you have to wrap this
call in a regular HTML select tag.
param: string[]  Choices
param: integer   Selected choice
return: string

options_from_collection_for_select($collection, $attribute_value,$attribute_text,$selected_value = null) X-Ref

Returns a string of option tags that have been compiled by
iterating over the +collection+ and assigning the result of a
call to the +value_method+ as the option value and the
+text_method+ as the option text. If +selected_value+ is
specified, the element returning a match on +value_method+ will
get the selected option tag.

Example (call, result). Imagine a loop iterating over each
+person+ in <tt>@project.people</tt> to generate an input tag:
options_from_collection_for_select(@project.people, "id", "name")
<option value="#{person.id}">#{person.name}</option>

NOTE: Only the option tags are returned, you have to wrap this call
in a regular HTML select tag.

select($object_name, $attribute_name, $choices,$options = array() X-Ref

Create a new FormOptionsHelper object and call its to_select_tag() method

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:
$person = new Person;
$people = $person->find_all();
foreach($people as $person) {
$choices[$person->id] = $person->first_name;
}
select("post", "person_id", $choices, array("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 functionault set of options in the
standard way: before r}ering the create form, a new model instance
is assigned the functional options and bound to
