ormar/docs/releases.md

0.7.4

• Allow multiple relations to the same related model/table.
• Fix for wrong relation column used in many_to_many relation joins (fix #73)
• Fix for wrong relation population for m2m relations when also fk relation present for same model.
• Add check if user provide related_name if there are multiple relations to same table on one model.
• More eager cleaning of the dead weak proxy models.

0.7.3

• Fix for setting fetching related model with UUDI pk, which is a string in raw (fix #71)

0.7.2

• Fix for overwriting related models with pk only in Model.update() with fields passed as parameters (fix #70)

0.7.1

• Fix for overwriting related models with pk only in Model.save() (fix #68)

0.7.0

• Breaking: QuerySet bulk_update method now raises ModelPersistenceError for unsaved models passed instead of QueryDefinitionError
• Breaking: Model initialization with unknown field name now raises ModelError instead of KeyError
• Added Signals, with pre-defined list signals and decorators: post_delete, post_save, post_update, pre_delete, pre_save, pre_update
• Add py.typed and modify setup.py for mypy support
• Performance optimization
• Updated docs

0.6.2

• Performance optimization
• Fix for bug with pydantic_only fields being required
• Add property_field decorator that registers a function as a property that will be included in Model.dict() and in fastapi response
• Update docs

0.6.1

• Explicitly set None to excluded nullable fields to avoid pydantic setting a default value (fix #60).

0.6.0

• Breaking: calling instance.load() when the instance row was deleted from db now raises NoMatch instead of ValueError
• Breaking: calling add and remove on ReverseForeignKey relation now updates the child model in db setting/removing fk column
• Breaking: ReverseForeignKey relation now exposes QuerySetProxy API like ManyToMany relation
• Breaking: querying related models from ManyToMany cleans list of related models loaded on parent model:
  • Example: post.categories.first() will set post.categories to list of 1 related model -> the one returned by first()
  • Example 2: if post has 4 categories so len(post.categories) == 4 calling post.categories.limit(2).all() -> will load only 2 children and now assert len(post.categories) == 2
• Added get_or_create, update_or_create, fields, exclude_fields, exclude, prefetch_related and order_by to QuerySetProxy so now you can use those methods directly from relation
• Update docs

0.5.5

• Fix for alembic autogenaration of migration UUID columns. It should just produce sqlalchemy CHAR(32) or CHAR(36)
• In order for this to work you have to set user_module_prefix='sa.' (must be equal to sqlalchemy_module_prefix option (default 'sa.'))

0.5.4

• Allow to pass uuid_format (allowed 'hex'(default) or 'string') to UUID field to change the format in which it's saved. By default field is saved in hex format (trimmed to 32 chars (without dashes)), but you can pass format='string' to use 36 (with dashes) instead to adjust to existing db or other libraries.

  Sample:

  • hex value = c616ab438cce49dbbf4380d109251dce
  • string value = c616ab43-8cce-49db-bf43-80d109251dce

0.5.3

• Fixed bug in Model.dict() method that was ignoring exclude parameter and not include dictionary argument.

0.5.2

• Added prefetch_related method to load subsequent models in separate queries.
• Update docs

0.5.1

• Switched to github actions instead of travis
• Update badges in the docs

0.5.0

• Added save status -> you can check if model is saved with ModelInstance.saved property
  • Model is saved after save/update/load/upsert method on model
  • Model is saved after create/get/first/all/get_or_create/update_or_create method
  • Model is saved when passed to bulk_update and bulk_create
  • Model is saved after adding/removing ManyToMany related objects (through model instance auto saved/deleted)
  • Model is not saved after change of any own field (including pk as Model.pk alias)
  • Model is not saved after adding/removing ForeignKey related object (fk column not saved)
  • Model is not saved after instantation with __init__ (w/o QuerySet.create or before calling save)
• Added Model.upsert(**kwargs) that performs save() if pk not set otherwise update(**kwargs)
• Added Model.save_related(follow=False) that iterates all related objects in all relations and checks if they are saved. If not it calls upsert() on each of them.
• Breaking: added raising exceptions if add-ing/remove-ing not saved (pk is None) models to ManyToMany relation
• Allow passing dictionaries and sets to fields and exclude_fields
• Auto translate str and lists to dicts for fields and exclude_fields
• Breaking: passing nested models to fields and exclude_fields is now by related ForeignKey name and not by target model name
• Performance optimizations - in modelproxy, newbasemodel - > less queries, some properties are cached on models
• Cleanup of unused relations code
• Optional performance dependency orjson added (strongly recommended)
• Updated docs

0.4.4

• add exclude_fields() method to exclude fields from sql
• refactor column names setting (aliases)
• fix ordering by for column with aliases
• additional tests for fields and exclude_fields
• update docs

0.4.3

• include properties in models.dict() and model.json()

0.4.2

• modify creation of pydantic models to allow returning related models with only pk populated

0.4.1

• add order_by method to queryset to allow sorting
• update docs

0.4.0

• Changed notation in Model definition -> now use name = ormar.Field() not name: ormar.Field()
  • Note that old notation is still supported but deprecated and will not play nice with static checkers like mypy and pydantic pycharm plugin
• Type hint docs and test
• Use mypy for tests also not, only ormar package
• Fix scale and precision translation with max_digits and decimal_places pydantic Decimal field
• Update docs - add best practices for dependencies
• Refactor metaclass and model_fields to play nice with type hints
• Add mypy and pydantic plugin to docs
• Expand the docs on ManyToMany relation

• Fix setting server_default as default field value in python

0.3.10

• Fix bug with selecting related ManyToMany fields with fields() if they are empty.
• Updated documentation

0.3.7
