Sphinx automodule: how to reference classes in same module?

You can reference a class like this:

class B(object):    """docs for B with reference to :class:`.A`"""    pass

Sphinx will intelligently try and figure out what you're referencing. If there are multiple classes with the name A, you might get a warning, but it should pick up the one in the current module.

Don't know if I understand the problem but this works flawlessly to me with autodoc, as per Cross-referencing Python objects

class FlowDirection(GeneralTable):    '''    Heat Flow Direction    :cvar int id: database primary key    :cvar unicode name: name     '''    def __repr__(self):        return u'<FlowDirection {0} instance at {1}>'.format(                self.name, hex(id(self))).encode('utf-8')    def __unicode__(self):        return self.nameclass AirCavityRes(GeneralTable):    '''    Air Cavity :term:`thermal resistance`    :cvar flow_direction: heat flow direction        (see :class:`FlowDirection`)    :cvar int id: database primary key    :cvar int if_fd: database foreign key to :class:`FlowDirection`    :cvar float res: :term:`thermal resistance`    :cvar float thick: thickness    '''    def __repr__(self):        return u'<AirCavityRes {0} instance at {1}>'.format(                self.res, hex(id(self)))
