나는 4.0.0 레일 3.0.1 friendly_id 사용하여 내 모델에서friendly_id가 SQL Server 및 tiny_tds에서 작동하지 않습니까?
(내가 레일 응용 프로그램에 대한 백엔드로 SQL Server 데이터베이스를 가지고 있기 때문에) 나는
extend FriendlyId
friendly_id :friendly_name, :use => [:slugged]
이 0.2.3을 tiny_tds하고 나는 레일 콘솔에서 클래스에 대한 새로운 기록을 만들려고 할 때, 나는 다음과 같은 오류가 발생합니다 :
ActiveRecord::StatementInvalid: TinyTds::Error: 'LENGTH' is not a recognized built-in function name.: SELECT TOP (1) [j_service_provider].* FROM [j_service_provider] WHERE ([slug] = N'' OR [slug] LIKE N'--%') ORDER BY LENGTH([slug]) DESC, [slug] DESC
이 SQL Server가 길이 기능이 없기 때문에, 그러나이다가 LEN 기능이 있습니다.
scope = scope.order("LEN(#{column}) DESC, #{column} DESC")
만들기 작품 : I가 충돌 방법에 slug_generator.rb에 라인 (48)에 대한 쿼리를 변경 그렇다면
.
그러나 find_each(&:save)을 실행해도 데이터베이스의 기존 레코드에 슬러그를 생성하는 것은 여전히 작동하지 않습니다.
tiny_tds를 사용하여 friendly_id가 SQL Server와 작동하도록하기 위해 필요한 다른 구성 변경이 있습니까?
ActiveRecord::StatementInvalid: TinyTds::Error: 'LENGTH' is not a recognized built-in function name.: SELECT TOP (1) [company].* FROM [company] WHERE ([slug] = N'' OR [slug] LIKE N'--%') ORDER BY LENGTH([slug]) DESC, [slug] DESC
