Debug your SQL with debug_sql
The to_sql method is a handy way to show your query, but as I’ve written about before, it has its shortcomings. When your query is going to eager load some records and has conditions referencing the eager loaded tables, ActiveRecord changes its generated query, but to_sql is none the wiser. Enter debug_sql:
 


  
  
 
   
 
    
ruby-1.9.2-head > Article.includes(:comments).where(:comments => {:body => 'hey'}).to_sql
 => SELECT "articles".* FROM "articles" WHERE ("comments"."body" = 'hey')
#
# LIES!!!
#
ruby-1.9.2-head > Article.includes(:comments).where(:comments => {:body => 'hey'}).debug_sql
 => SELECT "articles"."id" AS t0_r0, "articles"."title" AS t0_r1,
           "articles"."body" AS t0_r2, "articles"."created_at" AS t0_r3,
           "articles"."updated_at" AS t0_r4, "articles"."lookup_id" AS t0_r5,
           "comments"."id" AS t1_r0, "comments"."article_id" AS t1_r1,
           "comments"."body" AS t1_r2, "comments"."created_at" AS t1_r3,
           "comments"."updated_at" AS t1_r4
    FROM   "articles" LEFT OUTER JOIN "comments"
           ON "comments"."article_id" = "articles"."id"
    WHERE  ("comments"."body" = 'hey')
# The (ugly) truth!
