rails 4.1 validation of arbitrary fields via hstore
it happens because hstore key/values are converted to strings, and when validation tries to validate attribute :en it always will be nil, so you could replace your read_attribute_for_validation method to:
def read_attribute_for_validation(attr_name) @data[attr_name.to_s]endnote: attr_name.to_s
also you could use store_accessor like:
store_accessor :content, :envalidates :en, presence: true
