class (metadata[, schema=None])

Metadata can be extracted from a database by instantiating an . Rather than instantiating this class directly, it is recommended to use the factory method .

• Creates an instance suitable for use with the given database.

  Usage:

• Parameters:	skip_invalid (bool) – Skip tables whose names are invalid python identifiers. literal_column_names (bool) – Use column-names as-is. By default, column names are “python-ized”, i.e. mixed-case becomes lower-case. bare_fields – SQLite-only. Do not specify data-types for introspected columns.
  Returns:	A dictionary mapping table-names to model classes.

  Introspect the database, reading in the tables, columns, and foreign key constraints, then generate a dictionary mapping each database table to a dynamically-generated Model class.
