Using :scoped with :history causes Unknown column '<table_name>.scope' when regenerating slug

[nneufeld]

If I have a model like this:

class Restaurant < ActiveRecord::Base
  extend FriendlyId
  belongs_to :city
  friendly_id :name, :use => [:scoped, :history], :scope => :city
end

The following will result in an ActiveRecord::StatementInvalid: Mysql2::Error: Unknown column 'restaurants.scope' exception:

restaurant = Restaurant.new
restaurant.city = City.new
restaurant.name = "Joe's Diner"
restaurant.save

restaurant.title = "Bob's Diner"
restaurant.slug = nil
restaurant.save # throws exception(Unknown column 'restaurants.scope' )

This pull request fixes the offending where condition to use friendly_id_slugs.scope

Coverage remained the same when pulling f42655a on nneufeld:history_scoped_unknown_column_fix into 97ed06e on norman:master.

What's the status of this? I also ran into this problem and am currently referencing nneufeld's fork in my Gemfile but would like to switch back to referencing the main repo as soon as possible.

Thanks!

@mynock I'm currently on friendly_id 5.0.4 via Rubygems and just ran into this issue.

Sorry for the very long response time. This is now merged, I'll push a new version soon.
