Aloha Nick,
Thanks, but that just controls the WHERE clause. I need to control
the SELECT clause.
Turns out this is *almost* really easy. All we need to do is this:
def find_page_with_overrides(options = {})
options.merge!(:select => 'foo, bar')
find_page_without_overrides(options)
end
alias_method_chain :find_page, :overrides
*except*
That in find_page, the first line reads:
def find_page(options = {})
options.assert_valid_keys :sorting, :per_page, :page, :count_includes
which prohibits the above from working. Bummer. I can of course
add :select to the assert_valid_keys, but I'd rather not.
