I don’t have any gems, just the new active storage!

Hey! I’m having the same issue. Any plans to merge this PR?

I commented acts_as_taggable_on :tags in my model while I ran the generator and it worked fine. Just uncommented the offending lines when it was done.

Using gem 'administrate', '~> 0.10.0'

For future visitors looking for the quickfix: gem "administrate", git: "https://github.com/thoughtbot/administrate"

In my case, the cause was the new Rails 5 attribute API. Worked by commenting those while generating the dashboard.
