Selection lists - need help

[erezbens]

Hi
Im trying to figure out how to make selection list work
My example for this is a Real estate web site
download the code here: http://www.qcm.co.il/real-estate.rar

I have a table named "assets" and a table named "settlements"
and a relationship between them

execute "alter table assets add constraint fk_asset_settelments   foreign key (settelment_id)  references settelments(id)"

in _form.rhtml the code is:

<p><label for="asset_settelment_id">Settelment</label><br />
<&#37;= collection_select(:asset, :settelment_id,  Settelment.find(:all, :order => "settelment"), :id, :settelment, options ={:prompt => "select"}, :class =>"settelment") %>
</p>

when I try to update an asset settelment I get this error:

NoMethodError in AssetController#update

undefined method `settelment_id=' for #<Asset:0x478694c>
RAILS_ROOT: ./script/../config/..
