Import breaks when two column backed attributes are aliased together

[skunkworker]

When a record has two column backed attributes that are aliased together, import breaks across the board because both column names are provided. I briefly looked to see if this was a code smell in ActiveRecord but have not been able to find anything definitive either way.

Take the following:

create_table :topics, force: :cascade do |t|
  t.string :author_name
  t.string :author_full_name
end

class Topic < ActiveRecord::Base
  alias_attribute :author_full_name, :author_name
end

When the record is trying to be imported. author_name will be specified twice in the import string.

Aha! Ok, thank you for getting to the root issue.

@leonidkroka here is a some more info about a failing scenario with alias_attribute. Any ideas how to make sure column names in the generated sql are unique in this scenario?
