Ruby rails - 如何找到多个选项？

Question

我想根据多个参数查找记录。并且这些参数有多个选项。

As "SELECT something FROM mytable WHERE user_name="xyz" and status=("Active" OR "Deleted")

我如何将其转换为 Rails 语句？

Person.find_by_user_name_and_status(user_name, status) # this doesn't take the OR operator 

Answer 1

我现在无法测试，但你试过了吗？

Person.find_all_by_user_name_and_status(user_name, ["active", "deleted"])

如果以上方法不起作用，这应该...

Person.where(:user_name => "xyz", :status => ["active", "deleted"])
# translates to:
# "select * from persons where username = 'xyz' and status in ('active', 'deleted')"

您应该查看 Rails Guide for Active Record:http://guides.rubyonrails.org/active_record_querying.html
