DialectBase()

class Ligare.database.schema.dialect.DialectBase

abstract property dialect: Dialect

get_dialect_schema(meta)

Return type:

str | None

get_full_table_name(table_name, meta)

If the dialect supports schemas, then the table name does not have the schema prepended. In dialects that don’t support schemas, e.g., SQLite, the table name has the schema prepended. This is because, when schemas are supported, the dialect automatically handles which schema to use, while non-schema dialects do not reference any schemas.

Return type:

str

static get_schema(meta)

Return type:

str | None

static iterate_table_names(dialect, schema_tables, table_name_callback)

Call table_name_callback once for every table in every Base.

op: The op object from Alembic. schema_tables: A dictionary of the tables this call applies to for every Base. table_name_callback: A callback executed for every table in schema_tables.

Return type:

None

supports_schemas: bool = False
