Ruby-on-rails – use the activity record in the IN clause of the library to create an integer list

scope :stats_tips_given, lambda {|date|
 where("created_at >=? AND tipper_id IN(?)",date, User.stats_users(date).collect(& :id).join(','))
 }

User.stats_users(date).collect(&:id)

User.stats_users(date).collect(&:id).join(',')

I am trying to use ActiveRecord to replicate some SQL functions. My question involves me Use ruby ​​connection method (not to be confused with SQL connection). This is my code:

scope :stats_tips_given, lambda {|date|
 where( "created_at >=? AND tipper_id IN(?)",date, User.stats_users(date).collect(&:id).join(','))
 }

but generated The sql query has the following results: SELECT “tip_events”.* FROM “tip_events” WHERE(created_at>=’2011-04-14′ AND tipper_id IN(‘4,5,11,17,22,48,54 ,65, 88,103,147,151,181,182,189,195,190,196,202,226,227,231,243,245,232,225,212,217,220,263,265,273, 281,282,284,286,293,271,299,300,309,310,312,318,321,30,303,297,397,333,346,362,368,377,386,389,392,353, 398,427,420,434,418,454,456,477,484,480,453,450,452,458,497,498,503,510,511,515,522,529,537,540,508, 499,524,521,502,542,546,548,557,559,571,575,576,581,587,562,580 , 544,567,565,573,577,597,606,619,620, 640,636,607,603,600,596,656,657,668,676,683,685,662,677,669,689,678,690,694,514,206,304,601,63,495, 150,344,691,490,545,634,222,288,534,630,569,323,697,489,394,568,661,672,130,381,590,205,527,474,184, 622 ‘))

If there is no single quotes around the list of numbers, then this query can be normal. How can I correct this?

You are using join to form a string. Just pass the actual array to it:

User.stats_users(date).collect(&:id)

Replace:

User.stats_users(date).collect(&: id).join(',')
