ThinkingSphinx,`time` 속성을 설정에 문제

Unfortunatelly 스핑크스는 단순히ThinkingSphinx,`time` 속성을 설정에 문제

class Place << ActiveRecord::Base 
#... relations 

define_index 
    #... 
    has breakfast_start, :as => breakfast_start 
end

rake ts:rebuild 속성을 time 필드를 변환 할 수 없습니다 생각 : 또한 해결하지

rake aborted! 

Cannot automatically map attribute breakfast_start in Place to an 
equivalent Sphinx type (integer, float, boolean, datetime, string as ordinal). 
You could try to explicitly convert the column's value in your define_index 
block: 
    has "CAST(column AS INT)", :type => :integer, :as => :column 

(See full trace by running task with --trace)

변경 구문 has "CAST(column AS INT)", :type => :integer, :as => :column에 :

ERROR: index 'place_core': sql_range_query: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'INT) AS `breakfast_start` FROM `places`

누구나 고쳐? 미리 감사드립니다.
