ecto 0.4.0

on Hex

Enhancements

• Provide Ecto.Model.build/2 and Ecto.Model.assoc/2 for building and retrieving associations as queries. It is recommended to import Ecto.Model into your modules
• Associations have been rewriten into a simpler and faster mechanism that does not require .get, .all and friends
• Add Repo.preload/2
• Ecto.Query.preload/3 now supports query joins to be given
• Allow dynamic values for join qualifiers and join tables
• Define a behaviour named Ecto.Associations which defines the callback functions required to be implemented by associations

Backwards incompatible changes

• Association proxies have been removed. This means post.comments returns Ecto.Associations.NotLoaded until post.comments has been explicitly preloaded. However, once preloaded, the comments list can be accessed directly
• Queryable implementation for associations has been removed. This means Repo.all post.comments no longer returns all comments. Instead use Repo.all Ecto.Model.assoc(post, :comments). It is recommended to import Ecto.Model into your modules
• join: p.comments has been removed in favor of join: assoc(p, :comments)
• assoc/2 in select is deprecated, please use Ecto.Query.preload/3 instead
• Ecto.Associations.Preloader.preload/3 was removed in favor of Repo.preload/2
