v3.0.0

3.0

We are starting the changelog fresh. See documentation/2.0-CHANGELOG.md in GitHub for the old changelogs.

Breaking Changes:

For a guide on adjusting to these breaking changes, see the upgrade guide

[Ash.Api] has been renamed to Ash.Domain, and references to the concept have been renamed as well, i.e in options and in the DSL
[Ash] we now call functions on this, isntead of the domain. i.e Ash.create and Ash.read. The generated functions are now marked as deprecated
[Ash] remove process context functionality. You can no longer store the actor/tenant in the context with Ash.set_actor and so on
[private?] deprecate private?: false in favor of the more explicit public?: true
[default_accept] default default_accept is now []
[action lifecycle] after transaction hooks cannot be added from inside of other lifecycle hooks
[Ash.NotLoaded] use %Ash.NotLoaded{} for unselected values, instead of nil
[require_atomic?] now defaults to true, requiring opt-out of atomic behavior
[authorization] default api.authorization.authorize to :by_default
[Ash.Registry] has been removed
[actions] domain must always be known when constructing changesets
[Ash.Notifier] requires_original_data?/2 callback defaults to false
[Ash.Notifier.PubSub] default to previous_values?: false, allowing notifications to be sent for atomic updates
[unknown inputs] all action invocations now use UnknownInput errors when given an input they don't accept
[policies] requires_original_data?/2 callback on checks defaults to false
[Ash.Calculation] has been renamed to Ash.Resource.Calculation
[Ash.Resource.Calculation] "strict mode" has been added and defaults to true. This causes only explicitly requested fields from relationships to be loaded
[Ash.Query.Calculation] positional arguments are now an options list
[calculations] anonymous function calculations in a resource now take lists and return lists, instead of a single record (like standard calculations do)
[context] The context argument passed to many different callbacks is now a struct, tailored to that specific context. For example, in a calculation you will receive an Ash.Resource.Calculation.Context
[after_action/before_action] These builtin changes now accept a 3rd context argument
[picosat_elixir] is now optional (simple_sat is now an alternative)
[Ash.Changeset] Ash.Changeset.new! has been removed
[Ash.Changeset] Ash.Changeset.new/2 has been removed (Ash.Changeset.new/1 is still available)
[Ash.Changeset] changeset.filters is now changeset.filter
[Ash.Changeset] reverse order of before action & before transaction hooks. They now run in the action they are added. They used to run in reverse order.
[Ash.CiString] Ash.CiString.new/1 returns nil on nil input
[belongs_to.attribute_writable?] add attribute_public? for controlling publicity, and default attribute_writable? to true.
[Ash.Filter.TemplateHelpers] removed, all functions needed for expressions are now defined in Ash.Expr
[Ash.Expr] keyword lists are no longer special cased in ash expressions, and requiring pinning like any other value.
[Ash.Resource] default read actions are now paginatable with keyset and offset pagination (but pagination is not required)
[Ash.Resource] default actions require explicit accept lists (or will use default_accept). i.e defaults [:read, create: [:first_name, :last_name]]
[Ash.Resource] simple_notifiers is now an option to use Ash.Resource, instead of being in the DSL at resource.simple_notifiers
[Ash.Flow] has been removed and put in its own package ash_flow. It is being deprecated in favor of Reactor
[Ash.Error] the implementation has been extracted out to Splode. Defining new Ash.Errors is now done by defining a new Splode.Error
[Ash.Query] swap position of sort order and arguments in calculation sorting, i.e instead of calculation: {:asc, %{...args}} it is now calculation: {%{...args}, :asc}
[Ash.Resource.Aggregate] add include_nil? aggregate option, and default it to false (so list and first aggregates do not consider nil values by default)
[Ash.Policy.FilterCheck] now accepts context arguments, like Ash.Policy.FilterCheckWithContext
[Ash.Policy.FilterCheckWithContext] has been removed, use Ash.Policy.FilterCheck

Features:

[Ash.Type] add new remove_nil_items? array type constraint (#1116)
[Ash.Query] Paginatable relationships (#1050)
[Ash.DataLayer] new calculate/3 callback that allows for data layers to compute the result of expressions outside the context of a query. Used to power Ash.calculate/3.
[validations] new builtin validations, attributes_present/2 and attributes_absent/2
[multitenancy] configurable multitenancy behaviour on read actions (#1030)
[Ash.Reactor] Add new change step type which can be used to modify changesets.
[Ash.Changeset] add Ash.Changeset.update_change/2 function and builtin change (#976)
[Ash.Domain] code interfaces can now be defined on the domain
[Ash.Domain] policies can now be defined on the domain, and will run before resource policies
[Ash.ToTenant] add Ash.ToTenant, allowing for passing arbitrary values as tenants
[Ash] add Ash.read_first (like Ash.read_one, but applies a limit automatically)
[Ash] support a second optional input option for create, update and destroy, allowing for things like Ash.create!(Post, %{text: "text"}, opts)
[sensitive?] support sensitive? option in query aggregate/calculation (#963)
[Ash.Resource] support require_reference?: false on code interfaces, for when an update or destroy action uniquely identifies a record (or for bulk update/destroy)
[Ash.Resource] notifiers can now be specified for specific actions, using the notifiers option
[mix ash.rollback] delegates to extensions to trigger their rollback tasks
[Ash.Query] add Ash.Query.apply_to/3, to "apply" the query to a set of records (i.e filter, sort, distinct, etc.)
[Ash.CustomExpression] Use Ash.CustomExpression to extend Ash's expression syntax in a data-layer agnostic way
[code interface] Code interface functions now support bulk actions, in a "do what I mean" way. For example: Domain.deactive(post) can also be Post |> Ash.Query.filter(active == true) |> Domain.deactive()

Improvements:

[Ash.Actions.Sort] allow providing a stream of records to sort, and performance improvements
[bulk actions] add read_action option to bulk actions (#1088)
[Ash.stream] support streaming with offset, or even no pagination
[Ash.DataLayer.Ets] add debug logging, similar to ecto query debug logging
[Ash.DataLayer.Ets] support update_query, destroy_query and Ash.Changeset.filter/2
[Embedded resources] don't add autogenerated_id to embeds if they don't have a primary key
[Ash.Resource] you can now omit the return type of generic actions, indicating it either succeeds or fails, returning :ok or {:error, error}
[Ash.Resource] Generic actions can now accept a Reactor module, running it directly. (#993)
[Ash.Resource] support allow_nil_input dsl option in update/destroy actions (#964)
[Ash.Resource] The filter option can now be supplied multiple times in read actions and in relationships. They will be combined with and
[Ash.Resource] private attributes can now be accepted as action inputs
[Ash.Expr] is now imported automatically into places you will likely use it, like changes, validations, checks and calculations.
[Ash.Query] is now required automatically in places you will likely use it, as above
[sortable?] fields may mark themselves as unusable in sorts by using sortable? false
[sensitive?] calculations and aggregates may now also be marked as sensitive?

Bug Fixes:

[Ash.Type] apply array type nil_items? constraint after item constraints are applied (#1115)
[Ash.DataLayer.Ets] fix ETS data layer's support for lateral joining
[bulk actions] ensure transaction is rolled back on data layer errors during streaming
[bulk actions] set notify?: true when return_notifications?: true is set
[Ash.Changeset] attributes_present?/2 -> attribute_present?/2
[Ash.Filter] don't eager evaluate type/3 because data layers require type information
[Ash.Changeset] when comparing identities for manage_relationship, we now properly cast the values. Before, "1" and 1 were not considered equal for integer primary keys/identity fields
Many more bug fixes were added, but few are relevant enough to list here
