python - How would I cross-reference a function generated by autodoc in Sphinx?

Question

I am using the Sphinx autodoc feature to generate documentation based on the docstrings of my Python library.

The syntax for cross referencing is found here

A label must precede the section in order to allow that section to be referenced from other areas of the documentation.

What I have is a .rst (ReStructeredText) file for one of my classes. It uses

.. autoclass:: classname
    :members:

To generate documentation for the class.

My question is, how would I reference the auto-generated methods of the class from another .rst document in the documentation? If I try to place a label within the method's docstring, Sphinx complains. If I try to place a label before the method heading, Sphinx doesn't recognize it.

Is there a simple way to do this, or will I have to explicitly write in my class file the method name and precede that with a label?

Here is an example a reference within the [Python documentation2 doing what I need (I am assuming it used the autodoc feature, though I don't know for sure)

You don't need to add labels. In order to refer to a Python class, method, or other documented object, use the markup provided by the Python domain.

For example, the following defines a cross-reference to the mymethod method:

:py:meth:`mymodule.MyClass.mymethod`

Or even simpler (since the Python domain is the default):

:meth:`mymodule.MyClass.mymethod`

The documentation of TextWrapper.wrap that you link to in the question includes two cross-references of this kind (click on "Show Source" to see the reST markup).
