Bug: uninitialized constant SiteCategorySerializer

I’m seeing the following when trying to re-build Discourse with the voting plugin:

NameError: uninitialized constant SiteCategorySerializer

Seems related to some recent refactoring in the plugin:

The last known “good” version I have tried with is the following:

I’m running Discourse version 2.3.2.

So you are saying voting plugin is no longer compatible with 2.3 (stable)?

Very likely, we changed some internal interfaces, we should be able to make it compatible though.

I just hit this today upgrading stable.
In case it is helpful to anyone or someone can suggest a better way, this is my temporary solution:


hooks:
  after_code:
    - exec:
        cd: $home/plugins
        cmd:
          - mkdir -p plugins
          - git clone https://github.com/discourse/discourse-voting.git
          - cd discourse-voting && git reset --hard 9b4f233b9d33a946f626597aaf3863d2305b8809 && cd ..

This is now fixed per:

https://github.com/discourse/discourse/commit/bd5fa1737d42a958bb5cda35ae5bab2464d4e084

and

https://github.com/discourse/discourse-voting/commit/d09feb47a0a10d4a3a4be262f7259cf0a268d9fd

Core change was backported to stable.
