will_paginate should clone query strings
Reported by rgiar | June 30th, 2008 @ 06:39 AM
to avoid regenerating a query string over and over, i reuse the same query. for example:
@@my_q = "select custom,other,and,another from cats where blah = 'blah'"
i then do:
Cat.paginate_by_sql(@@my_q, 1, 13)
and deep inside paginate_by_sql (lib/will_paginate/finder.rb:133) it does this:
add_limit! query, :offset => pager.offset, :limit => pager.per_page
which destructively changes the string. the .dup business in the lines above almost avoids modifying the input string, but barely misses.
