Im using postgres and using HSTORE
In User model store_accessor :filter_options, :makes, :cities, :bodies, :detail_types, :engines, :transmissions
then I do self.filter_options = new_options
self.save
=> true
self.filter_options => {"makes"=>"[2]", "cities"=>"[1, 2, 3, 4, 5, 6, 7, 8]", "bodies"=>"[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11]", "engines"=>"[1, 2, 3, 4, 5, 6]", "detail_types"=>"[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11]", "transmissions"=>"[1, 2, 3, 4, 5, 6]"}
As we see it is stored correctly, but if I refresh the page or do self.reload, it is rolled back
self.reload.filter_options => {"makes"=>"[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100, 101, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111]", "cities"=>"[1, 2, 3, 4, 5, 6, 7, 8]", "bodies"=>"[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11]", "engines"=>"[1, 2, 3, 4, 5, 6]", "detail_types"=>"[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11]", "transmissions"=>"[1, 2, 3, 4, 5, 6]"}
Rogue after_initialize callback has invaded my model, problem solved
