Error when installing on Discourse v2.0.0.beta9

[dustinkeib]

My ruby is inadequate, so I would appreciate some help! Relevant log output:

rake aborted!

Sorry, @dustinkeib it looks like there are breaking changes in Discourse (similar issue here last year).
We aren't using Discourse actively any longer, I will try and make some time to have a look - but it might be worth asking the community to help - happy to accept a PR to fix the issue!

[dustinkeib]

@troykelly Thank you, I will see if I can resolve and issue a PR if so.

[dustinkeib]

@troykelly Out of curiosity, what are you using these days? Curious if there's something better out there.

[troykelly]

@dustinkeib we moved some to Ghost, when we have a more "community" engaged need - we will probably use Discourse again. We just had to put some projects on hold while we work on our core product.

[dustinkeib]

@troykelly Thank you!

[dustinkeib]

(Keeping open for the community, in case someone has a solution)

[troykelly]

@dustinkeib Let's keep it open so I remain aware of it. Not sure where it will sit priority wise - but would be good to get it working with current versions.

FYI: This fork seems to have fixed before_filter->before_action (and a bunch of others)

@tmacedo @troykelly @dustinkeib my PR fixes this up, in case you’d like to merge it in.
