Unreleased

Nothing yet.

1.0.2 - 2017-02-07

Added

  • BabySqueel::Association now has #== and #!=. This is only supported for Rails 5+. Example: Post.where { author: Author.last }.

Fixed

  • Incorrect alias detection caused by not tracking the full path to a join (#37).

1.0.1 - 2016-11-07

Added

  • Add DSL#_ for wrapping expressions in Arel::Node::Grouping. Thanks to @odedniv.

Fixed

  • Use strings for attribute names like Rails does. Symbols were preventing things like unscope from working. Thanks to @chewi.
  • where.has {} will now accept nil.
  • Arel::Nodes::Function did not previously include Arel::Math, so now you can do math operations on the result of SQL functions.
  • Arel::Nodes::Binary did not previously include Arel::AliasPredication. Binary nodes can now be aliased using as.

1.0.0 - 2016-09-09

Added

  • Polyamorous. Unfortunately, this does monkey-patch Active Record internals, but there just isn't any other reliable way to generate outer joins. Baby Squeel, itself, will still keep monkey patching to an absolute minimum.
  • Within DSL blocks, you can use exists and not_exists with Active Record relations. For example: Post.where.has { exists Post.where(title: 'Fun') }.`
  • Support for polymorphic associations.

Deprecations

  • Removed support for Active Record 4.0.x

Changed

  • BabySqueel::JoinDependency is no longer a class responsible for creating Arel joins. It is now a namespace for utilities used when working with the ActiveRecord::Association::JoinDependency class.
  • BabySqueel::Nodes::Generic is now BabySqueel::Nodes::Node.
  • Arel nodes are only extended with the behaviors they need. Previously, all Arel nodes were being extended with Arel::AliasPredication, Arel::OrderPredications, and Arel::Math.

Fixed

  • Fixed deprecation warnings on Active Record 5 when initializing an Arel::Table without a type caster.
  • No more duplicate joins. Previously, Baby Squeel did a very poor job of ensuring that you didn't join an association twice.
  • Alias detection should now actually work. The previous implementation was naive.

0.3.1 - 2016-08-02

Added

  • Ported backticks and #my from Squeel

Changed

  • DSL#sql now returns a node wrapped in a BabySqueel proxy.

0.3.0 - 2016-06-26

Added

  • Added Squeel compatibility mode that allows select, order, joins, group, where, and having to accept DSL blocks.
  • Added the ability to query tables that aren't backed by Active Record models.
  • Added BabySqueel::[], which provides a BabySqueel::Relation for models, or a BabySqueel::Table for symbols/strings.

Changed

  • Renamed BabySqueel::Association::AliasingError to BabySqueel::AssociationAliasingError.

0.2.2 - 2016-03-30

Added

  • Support for group (grouping) and having (when_having).
  • Support for sifters.
  • Added quoted and sql helpers for quoting strings and SQL literals.
  • More descriptive error messages when a column or association is not found.

Fixed

  • Arel::Nodes::Grouping does not include Arel::Math, so operations like (id + 5) + 3 would fail unexpectedly.
  • Fix missing bind values When joining through associations with default scope.
  • Removed ActiveRecord::VERSION specific handling of the WhereChain.

0.2.1 - 2016-03-27

Added

  • Support for subqueries.

Fixed

  • Some Arel nodes did not have access to as expressions.

0.2.0 - 2016-03-25

Added

  • References to aliased joins in a select, where, or order expression now use the aliased table name.

Changed

  • Rely on ActiveRecord::Relation#join_sources for the implicit construction of join nodes, rather than using the ActiveRecord::Associations::JoinDependency directly.

Fixed

  • Associations referencing the same table weren't being aliased.

[0.1.0] - 2016-03-16

Added

  • Initial support for selects, orders, wheres, and joins.
