[docs]class AnyBlokCore(Blok): """This Blok is required in all AnyBlok applications. This Blok provides the main fonctionalities for Bloks management (install, update, uninstall…). It also brings the representation of Anyblok objects (Models, Fields, etc.) within the database itself, and some fundamental facilities. * Core Models These are pure code Models, used as base classes: - Base: inherited by all Models - SqlBase: inherited by all models backed by an SQL table - SqlViewBase: inherited by all models bacled by an SQL view * System Models These correspond to actual tables in the table. They provide reflection or fundamental facilities. - Blok: represent all *available* Bloks, with their state and more - Model - Field - Column - Relationship - :class:`Sequence <.system.sequence.Sequence>`: database sequences, for use in applications. - :class:`Parameter <.system.parameter.Parameter>`: application parameters """ version = version autoinstall = True priority = 0 author = 'Suzanne Jean-Sébastien' logo = '../anyblok-logo_alpha_256.png' def pre_migration(self, latest_version): if latest_version is not None and latest_version < '0.4.1': self.pre_migration_0_4_1_fields_become_polymorphic(latest_version) def pre_migration_0_4_1_fields_become_polymorphic(self, latest_version):"Pre Migration %s => %s: Field, Column, Relation Ship " "become prolymophic models" % (latest_version, self.version)) system_field = self.registry.migration.table('system_field') system_field.column().add(self.registry.System.Field.entity_type) self.registry.execute( "UPDATE system_field SET entity_type='Model.System.Field'") query = """ INSERT INTO system_field ( name, model, code, label, ftype, entity_type) SELECT name, model, code, label, ftype, '%(entity_type)s' AS entity_type FROM %(table)s """ self.registry.execute( query % {'entity_type': 'Model.System.Column', 'table': 'system_column'}) self.registry.execute( query % {'entity_type': 'Model.System.RelationShip', 'table': 'system_relationship'}) system_column = self.registry.migration.table('system_column') system_column.column('code').drop() system_column.column('ftype').drop() system_column.column('label').drop() system_relationship = self.registry.migration.table( 'system_relationship') system_relationship.column('code').drop() system_relationship.column('ftype').drop() system_relationship.column('label').drop() @classmethod def import_declaration_module(cls): from . import core # noqa from . import system # noqa from . import authorization # noqa from . import documentation # noqa @classmethod def reload_declaration_module(cls, reload): from . import core reload(core) from . import system reload(system) from . import authorization reload(authorization) from . import documentation reload(documentation)
