Question

When I try:

User.find_by_region_id(234).order("id desc")

I get an error saying undefined method ‘order’

Do I have to use a different query style?

Answer 1

You want:

User.order("id desc").find_by_region_id(234)

This is because find_by_xxx returns a model object whereas order will return a ActiveRecord::Relation, which you can then do further querying to.

If you wanted to retrieve all results where the region_id is 234 and you want to order, you can do the method calling as you would expect.

User.where(:region_id=>234).order("id desc")

because where returns a ActiveRecord::Relation
