레일 방법 사이 arel하고있다 LT와 날짜 쿼리를 얻기

Question

I 날짜를 큰 이상의 특정 날짜 또는 보다 작거나 심지어 .this 인 arel와 두 간의 지정된 날짜를 날짜 싶어 내 컨트롤러 :

@from_time = search[:value][:from_time] 
@to_time = search[:value][:to_time] 
letters_query = letters[@key].between(@from_time..@to_time) 
@letters = Letter.joins(:official).where(letters_query) 

는이 내가 내 컨트롤러에 전달하는 JSON입니다

Parameters: {"query"=>{"search"=>{"0"=>{"key"=>"letter_date", "value"=>{"from_time"=>"01/09/1395", "to_time"=>"30/09/1395"}, "type"=>"date"}}}} 

필자는 매개 변수를 얻는 것에 대해 확신하지만 내 날짜는 태양 종류라고 기록됩니다.

If you are passing user input to a predicate, you must either give an appropriate type caster object to the `Arel::Table`, or manually cast the value before passing it to Arel. 
    DEPRECATION WARNING: Passing a column to `quote` has been deprecated. It is only used for type casting, which should be handled elsewhere. See https://github.com/rails/arel/commit/6160bfbda1d1781c3b08a33ec4955f170e95be11 for more information. (called from p at /home/afsane/Desktop/Afsane Development/Production/isecretariat/app/controllers/searches_controller.rb:511) 
    DEPRECATION WARNING: table_exists? is deprecated and will be removed from Rails 5.1 (use #data_source_exists? instead) (called from p at /home/afsane/Desktop/Afsane Development/Production/isecretariat/app/controllers/searches_controller.rb:511) 
    Arel performing automatic type casting is deprecated, and will be removed in Arel 8.0. If you are seeing this, it is because you are manually passing a value to an Arel predicate, and the `Arel::Table` object was constructed manually. The easiest way to remove this warning is to use an `Arel::Table` object returned from calling `arel_table` on an ActiveRecord::Base subclass. 

    If you're certain the value is already of the right type, change `attribute.eq(value)` to `attribute.eq(Arel::Nodes::Quoted.new(value))` (you will be able to remove that in Arel 8.0, it is only required to silence this deprecation warning). 

    You can also silence this warning globally by setting `$arel_silence_type_casting_deprecation` to `true`. (Do NOT do this if you are a library author) 

    If you are passing user input to a predicate, you must either give an appropriate type caster object to the `Arel::Table`, or manually cast the value before passing it to Arel.

나는이 사용하는 작은 : 나는이 많이 테스트하고 모든 문제가이 라인 함께

letters_query = officials[@key].lt(@to_time) 
letters_query = officials[@key].gt(@from_time) 

을 :

@letters = Letter.joins(:official).where(letters_query) 

는이 오류를 반환

아이디어가 있습니까?

Answer 1

,이 날짜에 적합한 쿼리를 생성하는 방법은 다음과 같습니다

letters = Letter.arel_table 
@letter = Letter.where(letters[:date].between(Date.new(2016,08,24)..Date.new(2016,09,24)) 

Answer 2

나는 보석에서 몇 년 동안 parsi-date을 사용할 수 있다고 생각합니다. 귀하의 질문은 나에게 비슷합니다. 그에 따라 쿼리 매개 변수를 구문 분석해야합니다. db에 저장된 날짜가 기독교 달력 형식 인 경우 to_gregorian을 수행합니다. arel와

@from_time = Parsi::Date.parse(search[:value][:from_time]).to_gregorian 
@to_time = Parsi::Date.parse(search[:value][:to_time]).to_gregorian
