python - How to make Sphinx Respect Importing Classes Into Package with __init__.py

Question

I have a package:

• foo
  • foo.py
  • bar.py
  • __init__.py

foo.py has a class Foo. In __init__.py I import class Foo so users can do:

from foo import Foo

Sphinx rightly documents Foo as foo.foo.Foo, which is right but confusing to users. How do I get Sphinx to document it as foo.Foo?

It's also important to get the overall module documentation associated with the right module.

Sphinx documents something called:

..module:: module.name

but when I use it in the first comment in a foo.py file, the doc is still attributed to foo.foo.

Answer 1

The value of the __module__ attribute is the name of the module in which a class/function/method was defined (see https://docs.python.org/2.7/reference/datamodel.html). The attribute is writable so it can be redefined in __init__.py:

Foo.__module__ = "foo"

Now if you use .. automodule:: foo, the qualified name of the Foo class will be shown as foo.Foo in the generated module documentation.

As an alternative to __module__-fiddling, you can use autoclass instead of automodule.

.. autoclass:: foo.Foo will produce the wanted output.
