How to do LIKE search across associations and paginate?

hi list,

using models with a legacy database:
class User < ActiveRecord::Base
set_table_name ‘ilt_insured_login_tbl’
set_primary_key ‘ilt_id’
set_column_prefix ‘ilt_’

has_many :policies, :foreign_key => ‘ilp_ilt_id’
end

class Policy < ActiveRecord::Base
set_table_name ‘ilp_insured_login_policy_tbl’
set_primary_key ‘ilp_ilt_id’
set_column_prefix ‘ilp_’

belongs_to :user, :foreign_key => ‘ilt_id’
end

… i want to paginate a search query looking at both models, e.g.

@user_pages, @users = paginate :users,
  {
    :per_page => 15,
    :order => 'lower(ilt_email)',
    :conditions => ["lower(ilt_email) like lower(?) or

lower(ilp_policy_num) like lower(?)", q, q],
:include => :policies
}

the API docs say that you cannot define conditions on an association if
using eager loading, and accordingly i get errors when trying the above
code

so, A: how would i perform such a query and B: how can i paginate the
results?

thanks,
jeff

well, a little more googling and found a solution:

works great for my situation.
