Fixing the broken slack auth plugin

(Andrew Camilleri) #1

Hi there guys! Just started messing around with a discourse instance and wanted to add authentication via slack. Found an existing plugin but it’s broken so I decided to try and patch it up however I am no ruby dev at all and don’t have an env to set up for local testing and whatnot. I’ve published my fixes to the plugin at GitHub - Kukks/oauth-slack-discourse: Discourse plugin to sign up using slack but the discourse builder fails on it and I’m unsure why. Can someone point me in the right direction? :slight_smile:

The code is almost identical to the linkedin auth plugin.

Do you mean it fails when running ./launcher rebuild app? Can you share the output please?

Thanks for replying @jomaxro.
Yup, that’s the one. Output below:

Perhaps try using GitHub - kmrshntr/omniauth-slack: omniauth-slack instead of ginjo-omniauth-slack? From a quick review it seems that the ginjo gem is deprecated.

(Andrew Camilleri) #5

According to this thread, ginjo should be a more or less fork of that repo

(Joshua Rosenfeld) #6

So it does. Sadly I can’t help much beyond that suggestion. I’ll note that it does appear to eventually install successfully later in the logs. Perhaps one of the community developers could offer better suggestions.
