2024-07-15 (6.0.1)

• Fix Django<4.2 pinning.

2024-07-11 (6.0)

• Improved performance of auth checks (especially has_field_access()).
• Changed method signature of UserScopes.has_all_scopes() and UserScopes.has_any_scopes() (most callers should use has_field_access() anyway.)
• Block deepcopy() of schema fields, as it's very slow.
• Removed DatasetType base class.
• Removed schema import events code, as its no longer used.
• Removed deprecated API's (schematools.utils and is_relation_temporal).
• Removed wirerope dependency.
• Removed Python 3.8 style annotations.

2024-03-04 (5.27.0)

• Add unit and description_with_unit properties to fields.

2024-03-04 (5.26.1)

• Change id_field to snake_case. It is directly used in sql queries.

2024-02-29 (5.26.0)

• Added extra id_field to Datasettable. Needs to be configurable for geosearch.

2024-01-07 (5.25.0)

2024-01-06 (5.24.1)

• Fix bug in exporter where a loop through dataset tables was prematurely left when a tables has not export data.

2024-01-06 (5.24.0)

• Do not write an empty export file if no columns are selected. Also fix the export to only use active records for jsonlines.

2024-01-31 (5.23.4)

• Bugfix in _is_valid_sql

2024-01-25 (5.23.3)

• Fix in _is_valid_sql to fix materialized view problem.

2023-12-28 (5.21.1)

• Fix auth property for subfields. The subfields do not have scopes, however, a scope can be defined on the parent field.

2023-12-20 (5.21.0)

• Added an extra helper method to user-scopes to determine if one of the fields has a scope that is blocking access.

2023-12-15 (5.20.1)

2023-12-15 (5.20.0)

• Change export to only use active records for csv and jsonlines, so, no historical records. Also brought the export more in line with the csv export of the DSO-API:
  • headers using capitalize()

• Add pre-commit hook for validating publishers

SUPPORTED METASCHEMAS: 1 2

Note that support is not guaranteed yet, for now this a declaration of intention. Any bugs should be reported.

SUPPORTED METASCHEMAS: 1 2

2022-12-19 (5.1.6)

• Removal of unused DatasetSchema.identifier property
• Add neuronId is mapping needed for through table identifiers

2022-12-14 (5.1.5)

• Mocked schemas now use properly camel-cased field names.
• Relations can be primary keys.
• The command schema batch-validate now works on table files as well as dataset.json files.

2022-12-13 (5.1.4)

• Fix importing schema files by using a relative path.
• Fix related_dataset_schema_ids to also detect changes in nested objects.
• Fix DatasetTableSchema.get_fields() to return cached instances too.
• Fix verbose_name of GeometryField in Django ORM, which reused globally defined data.

• Cleanup SQLAlchemy column creation logic.
• The schema validator now rejects tables with both an 'id' field and a composite primary key.

2022-12-01 (5.1.3)

• Fix limit_tables_to issue with crash in index creation for skipped tables.
• Fix limit_tables_to issue for M2M relations, now reports the table is not available.

2022-11-21 (5.1)

A big change in schema loading.

This mostly affects unit tests in other projects, or files that do custom schema loading. Unit test code should preferably use a schema_loader instance per test run, as all datasets are only cached within the same loader instance now.

• Added schematools.loaders.get_schema_loader() that provides a single object instance for loading.
• Added DatasetSchema.table_versions mapping to access other table versions by name.
• Added Record.source attribute to BaseImporter.load_file() and parse_records() return values. This allows callers to inspect the source record, e.g. for cursor handling.
• Removed TableVersions injection in dataset schema data. Tables are now loaded on demand.
• Removed internal global dataset cache, datasets are only cached per loader.
• Removed ununsed functions in schematools.utils.
• Deprecated loading functions in schematools.utils, use schematools.loaders instead.

2022-11-15 (5.0.2)

• Using BigAutoField for all identifier fields now by default.
• Fixed Django system check warnings for AutoField/BigAutoField migration changes.
• Fixed CKAN metadata upload to https://data.overheid.nl/ for datasets without a description or title.

2022-11-02 (5.0.1)

• Added validation check to prevent field names from being prefixed with their table or dataset name.
• Fixed Django db_column for subfields that use a shortname (regression by 5.0).
• Fixed dependency pinning of shapely to 1.8.0

2022-10-31 (5.0)

A major new release that cleans up various internal API's.

• Added many improvements to creating mock data.

• Changed CLI arguments for mocking to be more intuitive.

• Changed schema loaders to return relative paths instead of dataset ID's.

• Changed test runner to skipping tests that require the database.

• Completely rewrote the NDJSON importer for simplicity.

• Fixed display/geometry field notation as exposed via dataset_field table.

• Fixed importing datasets from the filesystem that are namespaced inside a subfolder.

• Fixed using schemaloader in Django management commands.

• Fixed saloger fixture leaking to every other test, flooding the console.

• New API's:

  • DatasetSchema:

    • python_name (formats as ClassName)
    • db_name (formats in snake_case)

  • DatasetTableSchema:

    • python_name (formats as ClassName)
    • short_name
    • through_fields (for through tables)

    • python_name
    • is_identifier_part
    • is_subfield
    • srid
    • related_fields
    • nested_table
    • through_table

• Changed API's:

  • DatasetTableSchema:

    • display_field returns actual field now.
    • temporal.dimensions returns actual fields now.
    • db_name() => db_name became a property for the typical common usage.
    • db_name_variant() provides the versioned-table support

  • DatasetFieldSchema:

    • db_name() => db_name - became a property for consistency
    • is_temporal => is_temporal_range
    • get_subfields() => subfields - no longer needs prefixes.

• Moved to_snake_case() / toCamelCase() imports to schematools.naming

• Deleted obsolete / unused functions:

  • DatasetTableSchema.name (use the id, db_name, or python_name instead).
  • get_dimension_fieldnames()
  • get_through_tables_by_id()
  • get_fields_by_id()
  • shorten_name()
  • _get_fk_fields()

• Removed DatasetTableSchema.get_subfields(add_prefixes=True) logic as the new naming attributes address that.

• Removed unused Docker stuff in consumer/ folder.

• Removed more-itertools dependency.
