I installed this gem for my refinerycms 4.0.3 app (with Rails 5.1) from the matho-update branch:

gem 'refinerycms-news', github: 'refinery/refinerycms-news', branch: 'matho-update'

In general, it was a good experience. However, the first migration failed with a message:

== 20200915155938 CreateNewsItems: migrating ==================================
rails aborted!
StandardError: An error has occurred, all later migrations canceled:

[FriendlyId] You need to translate the 'slug' field with Mobility (add 'translates :slug' in your model 'Refinery::News::Item')
/usr/local/rvm/gems/ruby-2.5.7@refinery403/gems/friendly_id-mobility-0.5.4/lib/friendly_id/mobility.rb:35:in `advise_against_untranslated_model'

In fact the model already contains translates :slug. I checked that by overriding the model first.

Anyway, I could run the migrations successfully after temporarily commenting out the function advise_against_untranslated_model in the friendly_id gem.

First I thought the error is raised because the field slug is not yet added to the table in this first migration, but only in a later migration. But it is not that simple. I rolled back all ten migrations, added the field slugto the create tablestatement of the first migration, and tried to migrate again. Still I got the same error.

BTW, in the rollback of the create table migration, ::Refinery::UserPlugin was not found, and also this gives an error (because delete_all does not take parameters):

::Refinery::Page.delete_all :link_url => "/news"

So I edited it to

::Refinery::Page.where(link_url: "/news").delete_all
