将Rails ActiveRecord转换为原始SQL

Question

In php codeigniter FW, I can do it easily by using get_compiled_select() method.

Is there any method that I can convert the query build by active record to raw sql. Ex:

User.find_by_name("abc")

should return raw query script something like

select * from user where name = "abc"

Answer 1

You can use to_sql (it gives you a sql query string, and can be called on any ActiveRecord association):

User.find_by_name("abc").to_sql
