to_select
========
This plugin extends Array and ActiveRecord::Base adding a method to_select() to
create options for select helpers.
In the case of ActiveRecord::Base it will do a find(:all) and return a list with
all those records using the :name field to show the option and the :id to identify
the record.
In the case of Array it will expect it to be an array of ActiveRecord objects and
do the same thing, create a list using name an id fields.
On both cases the name field can be overriden using a parameter.
Example
=======
<% form_for @account do |form| %>
<%= f.select :branch_id, Branch.to_select %>
<% end %>
or
<% form_for @account do |form| %>
<%= f.select :branch_id, @branches.to_select %>
<% end %>
You can override the field name using a parameter:
<%= f.select :person_id, @people.to_select(:last_name) %>
Aditional Parameters
====================
* Conditions
<% form_for @account do |form| %>
<%= f.select :branch_id, Branch.to_select(:name, :conditions => {:active => true}) %>
<% end %>
* Default values

<% end %>
