Hello,

I have just switch to Edge Rails and using validates_uniqueness_of: I have this error ( what is strange is that I don't have this error with another Model that uses validates_uniqueness_of ....)

Model   validates_uniqueness_of :user_id

Error wrong number of arguments (1 for 2) vendor/rails/activerecord/lib/active_record/validations.rb:698:in `exists?' vendor/rails/activerecord/lib/active_record/validations.rb:698:in `validates_uniqueness_of' vendor/rails/activerecord/lib/active_record/base.rb:1927:in `with_scope' vendor/rails/activerecord/lib/active_record/base.rb:1935:in `with_exclusive_scope' vendor/rails/activerecord/lib/active_record/validations.rb:697:in `validates_uniqueness_of' vendor/rails/activerecord/lib/active_record/validations.rb:400:in `validates_each' vendor/rails/activerecord/lib/active_record/validations.rb:397:in `each' vendor/rails/activerecord/lib/active_record/validations.rb:397:in `validates_each' vendor/rails/activesupport/lib/active_support/callbacks.rb:182:in `call' vendor/rails/activesupport/lib/active_support/callbacks.rb:182:in `evaluate_method' vendor/rails/activesupport/lib/active_support/callbacks.rb:166:in `call' vendor/rails/activesupport/lib/active_support/callbacks.rb:90:in `run' vendor/rails/activesupport/lib/active_support/callbacks.rb:90:in `each' vendor/rails/activesupport/lib/active_support/callbacks.rb:90:in `send' vendor/rails/activesupport/lib/active_support/callbacks.rb:90:in `run' vendor/rails/activesupport/lib/active_support/callbacks.rb:277:in `run_callbacks' vendor/rails/activerecord/lib/active_record/validations.rb:969:in `valid_without_callbacks?' vendor/rails/activerecord/lib/active_record/callbacks.rb:285:in `valid?' vendor/rails/activerecord/lib/active_record/validations.rb:948:in `save_without_dirty' vendor/rails/activerecord/lib/active_record/dirty.rb:79:in `save_without_transactions' vendor/rails/activerecord/lib/active_record/transactions.rb:128:in `send' vendor/rails/activerecord/lib/active_record/transactions.rb:128:in `with_transaction_returning_status' vendor/rails/activerecord/lib/active_record/connection_adapters/ abstract/database_statements.rb:66:in `transaction' vendor/rails/activerecord/lib/active_record/transactions.rb:82:in `transaction' vendor/rails/activerecord/lib/active_record/transactions.rb:90:in `transaction' vendor/rails/activerecord/lib/active_record/transactions.rb:127:in `with_transaction_returning_status' vendor/rails/activerecord/lib/active_record/transactions.rb:98:in `save_without_after_commit_callback' vendor/rails/activerecord/lib/active_record/transactions.rb:110:in `rollback_active_record_state!' vendor/rails/activerecord/lib/active_record/transactions.rb:98:in `save_without_after_commit_callback' vendor/plugins/thinking-sphinx/lib/thinking_sphinx/active_record/ delta.rb:38:in `save' app/controllers/evaluations_controller.rb:24:in `create'

Has anyone any ideas ? :slight_smile:

Thank you very much,

Have you overridden the method exists? on that model? The default implementation takes one argument and your stacktrace implies that it's expecting two. The uniqueness validation relies on this method now, which is why you didn't see it earlier.
