Sat, 28 Aug 2010 15:37:36 UT
merge_conditions seems to be gone from rails 3. Is there something in Rails 3 or Arel that would allow me to achieve the same thing, which is to merge various types of conditions (array, hash, etc)? I haven't spent much time with Arel, so I may be missing something obvious. Thanks
