ruby-on-rails - Railsの：conditionsのIN句

Question

Rails 2で作業していますが、クエリを実行したい

PunchingInformation.all(
  :select => "users.id, login, firstname, lastname, 
    sec_to_time(avg(time_to_sec(punching_informations.punch_in_time))) as 'avg_pit',
    sec_to_time(avg(time_to_sec(punching_informations.punch_out_time))) as 'avg_pot'",
  :joins => :user,
  :group => "users.id",
  :conditions => { 
    "punching_informations.date between '#{start_date}' and '#{end_date}'", 
    ["punching_informations.user_id IN (?)", employees.map { |v| v.to_i } ]
  }
)

しかし、それは常に次のようなエラーを返します

Mysql :: Error：不明な列'punching_informations.date between' 2012-09-01'and' 2012-09-25''in' whereclause'：SELECT users.id、login、firstname、lastname、sec_to_time（avg（time_to_sec （punching_informations.punch_in_time）））as'avg_pit'、sec_to_time（avg（time_to_sec（punching_informations.punch_out_time）））as'avg_pot' FROM punching_informations INNER JOIN usersON users.id = punching_informations.user_id AND（users。type=' User'OR users。type='AnonymousUser' ）WHERE（.IN（'punching_informations.user_id IN（？）'、'--- \ n- 28 \ n- 90 \ n'））GROUP BY punching_informationsusers.iddate between '2012-09-01' and '2012-09-25'

君の力が必要。

Answer 1

意味は少しわかりませんが（配列はありますが、中かっこ{}をハッシュのように取り込んでいます）、rubyは最初の文字列（"punching_informations.date between '#{start_date}' and '#{end_date}'"）を列として扱い、2番目の配列を期待値の配列として扱うようです。無効なIN条件。

おそらく、次のように書き直せばうまくいくでしょう

:conditions => { 
   [ "(punching_informations.date between '#{start_date}' AND '#{end_date}') AND punching_informations.user_id IN (?)", employees.map { |v| v.to_i } ]
 }

またはさらに良い

:conditions => { 
   [ "(punching_informations.date between ? AND ?) AND punching_informations.user_id IN (?)", start_date, end_date, employees.map { |v| v.to_i } ]
 }

Answer 2

selectにpunching_informations.dateとpunching_informations.user_idを追加します

：select => "punching_informations.date、punching_informations.user_id、users.id、...。
