Static alias to auto generated section URLs with ReST / Sphinx

I have a web application with some "Help" buttons which point to my online documentation. The links to the help sections are hardcoded in the app database. Previously, the documentation was made in HTML and JS, and I could control the URLs to the section manually.

However, now that I am migrating to Sphinx and ReST, I found the automatic section URL generation great, but cannot figure out how to control this behaviour for my structure.

Is there a way to have a sort of URL alias which point to the actual URL of my documentation in order not to update the hardcoded links in the app db everytime I update the name of my chapters/sections?

For instance:

• I have a subsection called "I like apples" in Chapter 1.
• My hardcoded link to it would be something like "Chapter1#I-like-apples" (I only care about the part following the # sign)
• I change the title to "I hate apples". The new link would become "Chapter1#I-hate-apples", but in my db I still need to have "#I-like-apples" which point to the same section.

See Hyperlink Targets in the docutils documentation, specifically "internal hyperlink targets".

.. _my-target:
.. _synonym-to-my-target:

My Subsection

Sphinx will generate targets for each synonym.

You could also do indirect hyperlink targets.

.. _my-target: synonym-to-my-target_
.. _synonym-to-my-target:
