elixir-ecto/ecto v1.1.0

on GitHub

Ecto v1.1.0 brings many improvements and bug fixes.

In particular v1.1.0 deprecates functionality that has been shown by developers to be confusing, unclear or error prone. They include:

• Ecto.Model's callbacks have been deprecated in favor of composing with changesets and of schema serializers
• Ecto.Model's optimistic_lock/1 has been deprecated in favor of Ecto.Changeset.optimistic_lock/3, which gives more fine grained control over the lock by relying on changesets
• Giving a model to Ecto.Repo.update/2 has been deprecated as it is ineffective and error prone since changes cannot be tracked
• Ecto.DateTime.local/0 has been deprecated
• The association and embedded functionality from Ecto.Changeset.cast/4 has been moved to Ecto.Changeset.cast_assoc/3 and Ecto.Changeset.cast_embed/3
• The association and embedded functionality from Ecto.Changeset.put_change/3 has been moved to Ecto.Changeset.put_assoc/3 and Ecto.Changeset.put_embed/3

Furthermore, the following functionality has been soft-deprecated (they won't emit warnings for now, only on Ecto v2.0):

• Ecto.Model has been soft deprecated. use Ecto.Schema instead of use Ecto.Model and invoke the functions in Ecto instead of the ones in Ecto.Model
