0.22.0

Added

  • Global constraints via meta.
  • Allow functional indexes.
  • Expose further parameters for UniqueConstraints.
  • no_copy attribute for fields.

Changes

  • Breaking: Factories pass now the kwargs as dict to get_pydantic_type, get_column_type, get_constraints. This allows now modifying the arguments passed down to the field.
  • Breaking: init_fields_mapping doesn't initializes the field stats anymore.
  • Breaking: model rebuilds are executed lazily when calling init_fields_mapping not when assigning fields manually anymore.

Fixed

  • Indexes and unique_together worked only for fields with columns of the same name.
  • MigrateConfig has no get_registry_copy.
  • Migrations have duplicate fks and crash.
  • ContentTypes were not copyable.
  • VirtualCascade was not automatically enabled.
  • Improve lazyness by splitting in two variable sets.

0.21.2

Added

  • PlaceholderField.
  • StrictModel which forbids extra attributes.

Changed

  • Validate on assignment is enabled.
  • IPAddressField uses now pydantic validation and a simplified TypeDecorator.

Fixed

  • Pydantic validators are fixed. Field based ones as well as model based ones.
  • __dict__ was wiped out when intializing a model.

0.21.1

Changed

  • Breaking: from_kwargs doesn't require model or table anymore. It is simply ignored.

Fixed

  • Q, and_, or_ support now complex kwargs like querysets.
  • Failure querying when using proxy model table and kwargs.
  • Proxy and main model use now the same tables. This could have been a problem when filtering against table columns of the proxy table in a query from the main table.
  • Queries operate now always on the main model not the proxy model.
  • Stacklevel of performance warning was wrong.

0.21.0

Added

  • Allow multi schema and database migrations.

  • Fix edgy wrapping esmerald with the asgi helper causing esmeralds cli to disappear.

0.20.0

Added

  • Add DurationField.
  • Allow passing max_digits to FloatField.
  • Add local_or function to QuerySets.

Changed

  • Only the main table of a queryset is queryable via model_class.columns.foo == foo. Select related models have now an unique name for their path. The name can be retrieved via tables_and_models or using f"{hash_tablekey(...)}_{column}".
  • Breaking: Alter tables_and_models to use the prefix as key with '' for the maintable and model.
  • Breaking: Functions passed to filter functions reveive now a second positional parameter tables_and_models.
  • build_where_clause conditionally uses a subquery.
  • Rename QueryType to QuerySetType. The old name stays as an alias.

Fixed

  • Triggering load on non-existent field when reflecting.
  • InspectDB mapping was incorrect.
  • Fix query edge cases.
  • Fix using related queries with update/delete.

0.19.1

Fixed

  • Migration issues with ManyToMany fields.
  • Wrong UUIDField type.
  • Passing options from Migrate to the alembic context.

0.19.0

Added

  • New SET_DEFAULT, and PROTECT to on_delete in the ForeignKey.
  • New through_tablename parameter for ManyToMany.

Removed

  • __db_model__ is removed. Replaced by registry = False.

Changed

  • Cleanup Model inheritance: Database related operations are put into a mixin. The customized metaclass is moved from EdgyBaseModel to edgy.Model as well as some db related ClassVars.
  • multi_related is now a set containing tuples (from_fk, to_fk). This can be used to identify fields used by ManyToMany fields.
  • Deprecate is_multi.
  • Deprecate parents. There are no users, it was undocumented and uses are limited.

Fixed

  • Non-abstract through-models wouldn't be marked as many to many relations.
  • Issues related with the Edgy shell initialization.

0.18.0

Added

  • ComputedField.
  • Permission template.
  • reverse_clean for ForeignKeys.
  • Expanded filter methods of querysets (can pass now dict and querysets).
  • Properly scoped with_tenant and with_schema.

Changed

  • Managers use now instance attributes (database, schema).
  • Expose as_select instead of raw_query.
  • model_fields contain now the fields so we can actually use the pydantic magic.

Fixed

  • select_related works across ManyToMany fields.

  • select_related would remove valid model instances because of non-existent related objects.
  • Fix identifying clashing column names in joins, so every model gets its right parameters.
  • Dependency tracking for join, so it doesn't depend on the order of select_related.
  • select_related entries work in any order and don't overwrite each other. -only and defer work on select_related.

  ...

0.17.4

Fixed

  • model_dump_json returns right result.

Fixed

  • Under circumstances it was possible for the assigned database attribute to appear as value.
  • Typings of some (class) properties are now correctly detected.

  • EXPLICIT_SPECIFIED_VALUES: when set, it returns a set of the keys from the explicitly specified values.

Changed

  • crawl_relationship has a slightly changed interface: it has cross_db_remainder as kwarg for callbacks and in the result. Also it doesn't raise NotImplementedError anymore when detecting a crossdb situation.
  • is_cross_db optionally gets a database as parameter and compares the databases instead of registries.
  • Relax fields parameter requirements for values/values_list.

Key features

  • Model inheritance - For those cases where you don't want to repeat yourself while maintaining integrity of the models.
  • Abstract classes - That's right! Sometimes you simply want a model that holds common fields that doesn't need to created as a table in the database.
  • Meta classes - If you are familiar with Django, this is not new to you and Edgy offers this in the same fashion.
  • Managers - Versatility at its core, you can have separate managers for your models to optimise specific queries and querysets at ease.
  • Filters - Filter by any field you want and need.
  • Model operators - Classic operations such as update, get, get_or_none, bulk_create, bulk_update, values, values_list, only, defer and a lot more.
  • Relationships made it easy - Support for OneToOne, ForeignKey and ManyToMany in the same Django style.
  • Constraints - Unique constraints through meta fields.
  • Indexes - Unique indexes through meta fields.
  • Native test client - We all know how hard it can be to setup that client for those tests you need so we give you already one.
