Collection_Select and Foreign keys

Hello all,
I have two models (Gallery and Gallery_Image). Gallery_Image has a
gallery_id property that acts as a foreign key. The model files look as
follows:

class Gallery < ActiveRecord::Base
has_many :Gallery_Images
end

class GalleryImage < ActiveRecord::Base
belongs_to :Gallery
end

I altered the _form.rhtml file for Gallery_Image to look like the
following:

<%= error_messages_for ‘gallery_image’ %>

Caption
<%= text_field 'gallery_image', 'caption' %>

Thumbnail path
<%= text_field 'gallery_image', 'thumbnail_path' %>

Fullsize path
<%= text_field 'gallery_image', 'fullsize_path' %>

Gallery
<%= @galleries = Gallery.find(:all, :order => "name") collection_select(:gallery_id, :gallery_id, @galleries, :id, :name) %>

The gallery_id value is not being set in the database. Do I need to do
something in the controller? I know this is a stupid noob question, but
I would very much appreciate the help.

Also, should I move the “@galleries = …” part into the
gallery_images_controller and out of the view? I would think that I
should, but it looks like it would end up being repeated in the
controller (since it would have to be there for both new and update).
Any thoughts?

Thanks,
Will

i am not sure about this but i think its your collection select in your
form
I am assuming your doing somehting like this in your controller for the
action of the form…

def create_gallery_image
@gallery_image = Gallery_Image.new(:params[:gallery_image])
end

if you are then your not passing all of the form details in the params
hash

try this:
collection_select(“gallery_image”, “gallery_id”, @galleries, :id, :name)

in place of this:
collection_select(:gallery_id, :gallery_id, @galleries, :id, :name)

Sorry about the slow response. That seemed to fix the issue. Man, this
framework is awesome!
