Reorder

stevo · Mar 27, 20127 thanks

If you want to override previously set order (even through default_scope), use reorder() instead.

E.g.

User.order('id ASC').reorder('name DESC')

would ignore ordering by id completely

Ordering on associations

rin · Oct 28, 20142 thanks

For ordering on the attribute of an associated model you have to include it:

Package.includes(:package_size).order("package_sizes.sort_order")

using hash as order

vitaly · Jan 12, 20141 thank

order can be specified as a hash, e.g.:

order(id: :desc)

This will prevent "ambiguous column" errors when the order is used with joins or includes.

Order with hash parameters only in ActiveRecord >= 4.0

spacelement · Oct 30, 20141 thank

If you use order with hash parameters on AR3 versions it wont work.

reorder

adding to stevo's comment that reorder is also usefull when you have default scope in your model. eg: default_scope -> { order(created_at: :desc) }
