The join_nodes must be passed to the JoinDependency initializer and therefore counted by the alias tracker. This is because the association_joins are aliased on initialization and then the tables are cached, so it is no use to alias the join_nodes later. Fixes #2556. 2011-08-29 10:01:17 -04:00
Deprecate eager-evaluated scopes. Don't use this: scope :red, where(color: 'red') default_scope where(color: 'red') Use this: scope :red, -> { where(color: 'red') } default_scope { where(color: 'red') } The former has numerous issues. It is a common newbie gotcha to do the following: scope :recent, where(published_at: Time.now - 2.weeks) Or a more subtle variant: scope :recent, -> { where(published_at: Time.now - 2.weeks) } scope :recent_red, recent.where(color: 'red') Eager scopes are also very complex to implement within Active Record, and there are still bugs. For example, the following does not do what you expect: scope :remove_conditions, except(:where) where(...).remove_conditions # => still has conditions 2012-03-21 18:18:18 -04:00			`scope :with_pet, -> { joins(:pet) }`
