The operators provided by the PostgreSQL version of :class:`_types.JSON` include: * Index operations (the ``->`` operator):: data_table.c.data['some key'] data_table.c.data[5] * Index operations returning text (the ``->>`` operator):: data_table.c.data['some key'].astext == 'some value' Note that equivalent functionality is available via the :attr:`.JSON.Comparator.as_string` accessor. * Index operations with CAST (equivalent to ``CAST(col ->> ['some key'] AS )``):: data_table.c.data['some key'].astext.cast(Integer) == 5 Note that equivalent functionality is available via the :attr:`.JSON.Comparator.as_integer` and similar accessors. * Path index operations (the ``#>`` operator):: data_table.c.data[('key_1', 'key_2', 5, ..., 'key_n')] * Path index operations returning text (the ``#>>`` operator):: data_table.c.data[('key_1', 'key_2', 5, ..., 'key_n')].astext == 'some value' Index operations return an expression object whose type defaults to :class:`_types.JSON` by default, so that further JSON-oriented instructions may be called upon the result type. Custom serializers and deserializers are specified at the dialect level, that is using :func:`_sa.create_engine`. The reason for this is that when using psycopg2, the DBAPI only allows serializers at the per-cursor or per-connection level. E.g.:: engine = create_engine("postgresql+psycopg2://scott:tiger@localhost/test", json_serializer=my_serialize_fn, json_deserializer=my_deserialize_fn ) When using the psycopg2 dialect, the json_deserializer is registered against the database using ``psycopg2.extras.register_default_json``. .. seealso:: :class:`_types.JSON` - Core level JSON type :class:`_postgresql.JSONB` Tc:t|||||_yy)aConstruct a :class:`_types.JSON` type. :param none_as_null: if True, persist the value ``None`` as a SQL NULL value, not the JSON encoding of ``null``. Note that when this flag is False, the :func:`.null` construct can still be used to persist a NULL value:: from sqlalchemy import null conn.execute(table.insert(), {"data": null()}) .. seealso:: :attr:`_types.JSON.NULL` :param astext_type: the type to use for the :attr:`.JSON.Comparator.astext` accessor on indexed attributes.

The :class:`_postgresql.JSONB` type stores arbitrary JSONB format data, e.g.:: data_table = Table('data_table', metadata, Column('id', Integer, primary_key=True), Column('data', JSONB) ) with engine.connect() as conn: conn.execute( data_table.insert(), data = {"key1": "value1", "key2": "value2"} ) The :class:`_postgresql.JSONB` type includes all operations provided by :class:`_types.JSON`, including the same behaviors for indexing operations. It also adds additional operators specific to JSONB, including :meth:`.JSONB.Comparator.has_key`, :meth:`.JSONB.Comparator.has_all`, :meth:`.JSONB.Comparator.has_any`, :meth:`.JSONB.Comparator.contains`, :meth:`.JSONB.Comparator.contained_by`, :meth:`.JSONB.Comparator.delete_path`, :meth:`.JSONB.Comparator.path_exists` and :meth:`.JSONB.Comparator.path_match`. Like the :class:`_types.JSON` type, the :class:`_postgresql.JSONB` type does not detect in-place changes when used with the ORM, unless the :mod:`sqlalchemy.ext.mutable` extension is used. Custom serializers and deserializers are shared with the :class:`_types.JSON` class, using the ``json_serializer`` and ``json_deserializer`` keyword arguments. These must be specified at the dialect level using :func:`_sa.create_engine`. When using psycopg2, the serializers are associated with the jsonb type using ``psycopg2.extras.register_default_jsonb`` on a per-connection basis, in the same way that ``psycopg2.extras.register_default_json`` is used to register these handlers with the json type. .. seealso:: :class:`_types.JSON` c@eZdZdZdZdZdZdZdZdZ dZ d Z y ) JSONB.Comparatorr=cN|jt|tjS)zBoolean expression.
