在 ActiveRecord 中 Rails Translate SQL raw

Question

I have this SQL query

sql = "select mt1.* from mail_templates as mt1 join mail_templates as mt2 where mt1.template_id = mt2.id AND mt1.technical_name='#{name}' AND mt2.festival_id=#{festival}"

If I execute this query with ActiveRecord::Base.connection.execute(sql).first it returns an array and I need to have a MailTemplate ActiveRecord.

I don't know how to do it.

Thanx for your help

Answer 1

I found the solution by using

sql = "select mt1.* from mail_templates as mt1 join mail_templates as mt2 where mt1.template_id = mt2.id AND mt1.technical_name='#{name}' AND mt2.festival_id=#{festival}"
MailTemplate.find_by_sql(sql)
