Rescue Activerecord Recordnotunique
Mysql2::Error: Duplicate entry for key — ActiveRecord::RecordNotUnique not catching error? up vote 3 down vote favorite 3 I am working on a rails app and have been getting the following error very often: Mysql2::Error: Duplicate entry '3022093-2000000028003-visited' for key 'unique_user_place_relationship' While I've narrowed the source of the problem down to the following lines: begin up = UserPlace.new(user_place_params) up.skip_logging up.save! rescue ActiveRecord::RecordNotUnique => e Rails.logger.warn(e) validates_uniqueness_of end In my table, I have the following indices: key_name seq_in_index column_name unique_user_place_relationship 1 user_id unique_user_place_relationship 2 place_id unique_user_place_relationship 3 relationship Is the problem that I don't have a validate_uniqueness_of user_id, place_id and relationship in my user_place.rb? From my understanding, ActiveRecord:RecordNotUnique should catch this error since the transaction does not meet the index constraints at the db level. ruby-on-rails ruby-on-rails-3 exception-handling share|improve this question edited Mar 6 '13 at 20:10 asked Mar 6 '13 at 19:51 Huy 4,05333170 2 Yes, you should have the validates_uniqueness_of in place in addition to the database-level constraints. –deefour Mar 6 '13 at 20:20 add a comment| 2 Answers 2 active oldest votes up vote 5 down vote accepted The doc say http://api.rubyonrails.org/classes/ActiveRecord/Validations/ClassMethods.html#method-i-validates_uniqueness_of-label-Concurrency+and+integrity : Using this validation method in conjunction with ActiveRecord::Validations#save does not guarantee the absence of duplicate record insertions, because uniqueness checks on the application level are inherently prone to race conditions. For example, suppose that two users try to post a Comment at the same time, and a Comment’s title must be unique. At the database-level, the actions performed by these users could be interleaved in the following man

So if you try to call save on a duplicate record, it raises ActiveRecord::StatementInvalid and shows the mysql error. Is there a way to handle this within rails either by creating the unique constraint, or otherwise have it return a relevant error message when this happens? heres the trace: ActiveRecord::StatementInvalid: Mysql::Error: Duplicate entry '2010-12-09-2-0-1-1' for key 2: INSERT INTO `entries` (`rejected_at`, `created_at`, `comments`, `overtime`, `submitted_at`, `updated_at`, `time`, `approved`, `day`, `user_id`, `approved_at`, `job_id`, `submitted`, `rejected`) VALUES(NULL, '2010-12-09 21:50:46', NULL, 0, NULL, '2010-12-09 21:50:46', 2.0, NULL, '2010-12-09', 1, NULL, 1, NULL, NULL) from /home/cmatthews/src/cannon/vendor/rails/activerecord/lib/active_record/connection_adapters/abstract_adapter.rb:219:in `log' from /home/cmatthews/src/cannon/vendor/rails/activerecord/lib/active_record/connection_adapters/mysql_adapter.rb:319:in `execute' from /home/cmatthews/src/cannon/vendor/rails/activerecord/lib/active_record/connection_adapters/abstract/database_statements.rb:259:in `insert_sql' from /home/cmatthews/src/cannon/vendor/rails/activerecord/lib/active_record/connection_adapters/mysql_adapter.rb:329:in `insert_sql' from /home/cmatthews/src/cannon/vendor/rails/activerecord/lib/active_record/connection_adapters/abstract/database_statements.rb:44:in `insert_without_query_di

It was only then that when I used rake in the application file that the tests began to run. However, now I keep getting this Mysql2::Error: Duplicate entry and I don't understand why. Could it be the fact that I have two mysqls located two different places on my computer? I am not really sure what is causing this problem because all the tables are empty. How can I fix this problem? Thank you for helping. I am new to Ruby on Rails and Mysql. The stack looks like the following: HomeControllerTest test_should_get_index ERROR Mysql2::Error: Duplicate entry '' for key 'index_admin_users_on_email': INSERT INTO `admin_users` (`created_at`, `updated_at`, `id`) VALUES ('2011-12-09 09:33:30', '2011-12-09 09:33:30', 298486374) STDERR: Exception `ActiveRecord::RecordNotUnique' at /Users/nick01s/.rvm/gems/ruby-1.9.3-p0/gems/activerecord-3.1.3/lib/active_record/connection_adapters/mysql2_adapter.rb:283:in `query' /Users/nick01s/.rvm/gems/ruby-1.9.3-p0/gems/activerecord-3.1.3/lib/active_record/connection_adapters/mysql2_adapter.rb:283:in `block in execute' /Users/nick01s/.rvm/gems/rub
work for, I got a notification that there was an error in the application. Someone was trying to add a new record and it was failing (500 ISE). I checked the logs and found the following: ActiveRecord::RecordNotUnique (Mysql2::Error: Duplicate entry '127' for key 1: INSERT INTO... It turns out that this problem is triggered when the id column is of type TINYINT which has a maximum signed value of 127. This of course causes the above error to occur when record 128 is entered. I was able to resolve this by changing the column type to INT using the MySQL client.
