Undefined method 'update' for MetricCacheInfo:Class (NoMethodError)

[bdouglasGitHub]

I received this error after trying to initiate the command: foreman start

foreman start 13:22:16 web.1 | started with pid 9221 13:22:18 web.1 | /services/descartes-master/lib/descartes/models/metrics.rb:30:in update': undefined methodupdate' for MetricCacheInfo:Class (NoMethodError)

I asked in the irc.frenode.net #ruby channel and they mentioned:

Thank you

This is a boilerplate use of the Sequel built-ins. The only reason you might get that error is if you haven't run your migrations. Are you still having this problem / trying to use Descartes?

[aphyr]

I'm hitting this as well, after an upgrade, migrations ran fine but I get a similar trace:

Sorry for the slow response.

@bdouglasGitHub your output shows that you're running an older version of that model. Had you tried updating your checkout? There were some fixes between your older checkout and master.

@aphyr Are you still using Descartes && is this still a problem for you && any idea how many metrics in your Graphite server?

[obfuscurity]

There were changes in Sequel 4.x, and I hadn't locked in the gem version to 3.x. so you were hitting that. This was fixed in https://github.com/obfuscurity/descartes/commit/6117f5348eda8e84b82886067d057eac44776df3.
