我经常需要使用rails c
在Rails控制台上运行。然后,我运行一些语句,该语句遍历模型的记录。我需要输出信息,但是所有的SQL代码也会变得乱七八糟。喜欢:
Students.all.each {|s| puts s.inspect unless s.attendance};nil
我把那个
nil
放在最后,这样我就不会收到所有学生的丑陋转储。这是输出: Student Load (4.3ms) SELECT "students".* FROM "students"
Attendance Load (3.6ms) SELECT "attendances".* FROM "attendances" WHERE "attendances"."id" = 2694 LIMIT 1
Attendance Load (2.7ms) SELECT "attendances".* FROM "attendances" WHERE "attendances"."id" = 2695 LIMIT 1
Attendance Load (4.9ms) SELECT "attendances".* FROM "attendances" WHERE "attendances"."id" = 2689 LIMIT 1
#<Student id: 3, attendance_id: 2689, teacher_id: 6, began_at: "2013-05-21 19:16:37", finished_at: "2013-05-21 20:34:33", created_at: "2013-05-21 19:16:37", updated_at: "2013-05-21 20:34:33">
Attendance Load (2.0ms) SELECT "attendances".* FROM "attendances" WHERE "attendances"."id" = 2692 LIMIT 1
#<Student id: 26, attendance_id: 2713, teacher_id: 6, began_at: "2013-05-21 22:44:25", finished_at: "2013-05-21 22:44:42", created_at: "2013-05-21 22:44:25", updated_at: "2013-05-21 22:44:42">
Attendance Load (1.6ms) SELECT "attendances".* FROM "attendances" WHERE "attendances"."id" = 2714 LIMIT 1
#<Student id: 27, attendance_id: 2714, teacher_id: 3, began_at: "2013-05-21 22:45:06", finished_at: "2013-05-21 22:45:27", created_at: "2013-05-21 22:45:06", updated_at: "2013-05-21 22:45:27">
Attendance Load (4.0ms) SELECT "attendances".* FROM "attendances" WHERE "attendances"."id" = 2712 LIMIT 1
在这里,实际上还算不错,但是有时仍然很难看清我想要的东西。抑制SQL输出的简便方法?
最佳答案
在控制台中输入此内容,或将其放入控制台的配置文件中:
ActiveRecord::Base.logger = nil
