intersphinx link to pandas autodoc API
autodoc, pandas, python, python-sphinx
Solution
Be careful with the spelling. All the cross-references in the question that use the `:meth:` role will work if `dataframe` is changed to `DataFrame`.
Problem
I'm attempting to link to the `apply()` autodoc documentation at: http://pandas.pydata.org/pandas-docs/dev/generated/pandas.DataFrame.apply.html. I can link to the release page at: http://pandas.pydata.org/pandas-docs/dev/release.html by using... ``` :ref:`release <pandas:release>` ``` ... but I can't seem to get the proper link to the autodoc pages. My intersphinx mapping is configured as... ``` {'python': ('http://docs.python.org/', None), 'pandas': ('http://pandas.pydata.org/pandas-docs/dev', None)}` ``` ... and I've tried the following variations of links to the `apply()` method: ``` :ref:`apply <pandas:pandas.dataframe.apply>` :ref:`apply <pandas:pandas-dataframe-apply>` :ref:`apply <pandas:dataframe.apply>` :ref:`apply <pandas:DataFrame.apply>` :ref:`apply <pandas.DataFrame.apply>` :ref:`apply <pandas.dataframe.apply>` :meth:`apply <pandas:pandas.dataframe.apply>` :meth:`pandas:pandas.dataframe.apply` :meth:`pandas.dataframe.apply` ``` Answer As mzjn answered below, the link is case sensitive so any of the following work in my situation: ``` :meth:`apply <pandas:pandas.DataFrame.apply>` :meth:`pandas:pandas.DataFrame.apply` :meth:`pandas.DataFrame.apply` ```
