Slash in indexes fails. acts-as-taggable-on

[emilkarl]

Tried this with an app that uses acts-as-taggable-on. A reccomended index looks like this but this fails with Rails 4. Any idea how to solve or should the index not be there?

add_index :taggings, [:acts_as_taggable_on/tag_id, :user_id]

@emilkarl that's a good question. can you provide a failing case with this or at least the model relevant info?

[jethroo]

have this in 3 models with association using class_name happens for has_many and belongs_to (not limited just seeing this for those two in my codebase)

class Corge < ActiveRecord::Base
  has_many   :foo_bars, class_name: Bar::Foo.name
  belongs_to :baz, class_name: Qux::Quux.name
end

results in:

add_index :corges, [:corge_id, :bar/foo_id]
add_index :corges, [:corge_id, :qux/quux_id]

@emilkarl @jethroo @SirRawlins @dandrews @olivierbuffon @matthewford which exact version of rails 4 are you using? I'm trying to reproduce it without success.

PS: if someone want to try to create a test case, it will be super helpfull.

@plentz

• Rails 4.2.2
• with 'spree' gem

the same result

add_index :spree_shipments, [:spree/adjustment_id, :spree/order_id]

I will make a PR for that.

[emilkarl]
