This type is a specialization of the Core-level :class:`_types.JSON` type. Be sure to read the documentation for :class:`_types.JSON` for important tips regarding treatment of NULL values and ORM use. .. versionchanged:: 1.1 :class:`_postgresql.JSON` is now a PostgreSQL- specific specialization of the new :class:`_types.JSON` type. 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 <type>)``):: 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' .. versionchanged:: 1.1 The :meth:`_expression.ColumnElement.cast` operator on JSON objects now requires that the :attr:`.JSON.Comparator.astext` modifier be called explicitly, if the cast works only from a textual string. 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://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` FNc �p �� t t | � � � |�� � |� || _ dS dS )a+ Construct 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()) .. versionchanged:: 0.9.8 - Added ``none_as_null``, and :func:`.null` is now supported in order to persist a NULL value. .. 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`, and :meth:`.JSONB.Comparator.contained_by`. 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. .. versionadded:: 0.9.7 .. seealso:: :class:`_types.JSON` c �0 � e Zd ZdZd� Zd� Zd� Zd� Zd� ZdS )�JSONB.Comparatorr@ c �P � | � t |t j �� � S )zvBoolean expression.
