Hello there,
I have the following models
class Bibliography < ActiveRecord::Base
has_and_belongs_to_many :gthemes, :join_table =>
"gthemes_bibliographies"
end
class Gtheme < ActiveRecord::Base
has_and_belongs_to_many :bibliographies, :join_table =>
"gthemes_bibliographies"
end
I want to include in the bibliography edit page a select box with all
the gthemes and i want the members of @bibliography.gthemes to be
marked as selected
I ''m using this in bibliography/_form.rhtml:
<%= select(''bibliography'', ''gthemes'' ,
Gtheme.find(:all).collect{ |gt|
[ gt.name, gt.id]}, {}, {:multiple => true}) %>
but it doesn''t mark the current gthemes as selected, any ideas?
Thanks in advance,
Christos
