Lockbox raises MissingAttributeError when encrypted attribute is backed by store_attribute when using select

[StanleyAu]

Take a hypothetical ActiveRecord:

class MyRecord < ApplicationRecord
    store_attribute :store, :secret_ciphertext, :string
    has_encrypted :secret
end

Fetch a record using select to limit columns returned:

record = MyRecord.select(:id).first

Attempt to call .attributes on record

record.attributes

# => ActiveRecord::MissingAttributeError: missing attribute: store

Seems to be due to use of send(encrypted_attribute) in https://github.com/ankane/lockbox/blob/master/lib/lockbox/model.rb#L469
whereas regular attributes come from the instance var @attributes

Hey @StanleyAu, I haven't tried the store_attribute gem (and it's not officially supported), but looking at the docs, you'll want to create a store_ciphertext column and use has_encrypted :store.

class MyRecord < ApplicationRecord
  store_attribute :store, :secret, :string
  has_encrypted :store
end
