Method attrs

lib/sqlalchemy/orm/mapper.py:2985–3020

A namespace of all :class:`.MapperProperty` objects associated this mapper. This is an object that provides each property based on its key name. For instance, the mapper for a ``User`` class which has ``User.name`` attribute would provide ``mapper.attrs.name

        associated this mapper.

        This is an object that provides each property based on
        its key name.  For instance, the mapper for a
        ``User`` class which has ``User.name`` attribute would
        provide ``mapper.attrs.name``, which would be the
        :class:`.ColumnProperty` representing the ``name``
        column.   The namespace object can also be iterated,
        which would yield each :class:`.MapperProperty`.

        :class:`_orm.Mapper` has several pre-filtered views
        of this attribute which limit the types of properties
        returned, including :attr:`.synonyms`, :attr:`.column_attrs`,
        :attr:`.relationships`, and :attr:`.composites`.

        .. warning::

            The :attr:`_orm.Mapper.attrs` accessor namespace is an
            instance of :class:`.OrderedProperties`.  This is
            a dictionary-like object which includes a small number of
            named methods such as :meth:`.OrderedProperties.items`
            and :meth:`.OrderedProperties.values`.  When
            accessing attributes dynamically, favor using the dict-access
            scheme, e.g. ``mapper.attrs[somename]`` over
            ``getattr(mapper.attrs, somename)`` to avoid name collisions.
