Perform a sanity check on your database through active record validation.
Add the following line to your Gemfile
gem 'active_sanity'
If you wish to store invalid records in your database run:
$ rails generate active_sanity
$ rake db:migrate
Just run:
rake db:check_sanity
ActiveSanity will iterate over every records of all your models to check weither they're valid or not. It will save invalid records in the table invalid_records if it exists and output all invalid records.
The output might look like the following:
model | id | errors
User | 1 | { "email" => ["is invalid"] }
Flight | 123 | { "arrival_time" => ["can't be nil"], "departure_time" => ["is invalid"] }
Flight | 323 | { "arrival_time" => ["can't be nil"] }
There is a bug in Rails 3.0.5 with the unserialization of OrderedHash storing arrays: only the last error of a given attribute gets retrieved from the database.
Usual fork & pull request.
This gem is quite simple so I experiment using features only. To run the acceptance test suite, just run:
bundle install
cucumber features
Using features only was kinda handsome until I had to deal with two different database schema (with / without the table invalid_records) in the same test suite. I guess that the same complexity would arise using any other testing framework.
