ecto 0.9.0

on Hex

Enhancements

• Add MySQL support
• Log when migration is already up/down
• Add Ecto.Association.loaded?/1
• Support joins besides where clauses in update_all and delete_all
• Support optimistic locking with Ecto.Model.OptimisticLock
• Allow timeout when querying the database to be configured via :timeout
• Allow timeout when connecting to the database to be configured via :connect_timeout
• Support maps in select in queries
• Allow custom macros to be used in queries
• Support distinct: true that simply sets SELECT DISTINCT

Backwards incompatible changes

• Primary keys are no longer automatically marked with read_after_writes. If you have a custom primary key that is AUTO INCREMENT/SERIAL in the database, you will have to pass read_after_writes: true as option when setting @primary_key
• Remove blank checks from Ecto.Changeset.cast/4 (you should automatically set the parameters values to nil before calling cast/4. If you are using Phoenix, Phoenix master has a plug :scrub_params, "user" for that)
• Ecto.Changeset.cast/4 now expects the changeset/model as first argument and the parameters as second
• Ecto.Query.distinct/3 can now be specified on queries just once
• Ecto.Associations renamed to Ecto.Association (unlikely to affect user code)

Deprecations

• The :adapter option should now be specified in the config file rather than when using Ecto.Repo (you will receive a warning if you don't)

Adapter API changes

• :time types now use a tuple of four elements (hour, min, sec and msec)
• Ecto.Adapter.update/6 now expects the fields as third argument and filters as fourth
• Ecto.Migration.Reference now have a default type of :serial that needs to be translated to the underlying primary key representation
• Ecto.Query now has a distinct field (instead of distincts) and its expression may true, false or a list
