Method: Mongo::Cursor#sort

Defined in:

lib/mongo/cursor.rb

#sort(key_or_list, direction = nil) ⇒ Object

Sort this cursor’s results.

This method overrides any sort order specified in the Collection#find method, and only the last sort applied has an effect.

Parameters:

• key_or_list (Symbol, Array) —

  either 1) a key to sort by or 2) an array of [key, direction] pairs to sort by. Direction should be specified as Mongo::ASCENDING (or :ascending / :asc) or Mongo::DESCENDING (or :descending / :desc)

Raises:

• (InvalidOperation) —

  if this cursor has already been used.

• (InvalidSortValueError) —

  if the specified order is invalid.
