ActiveRecord::DataIntegrity

Checks your ActiveRecord models to match data integrity principles and rules. Out of the box it detects many issues such as the lack of foreign keys.

Intallation

group :development do
  ...
  gem 'activerecord-data_integrity', require: false
end

Quickstart

Run data_integrity CLI-tool in your Rails project's folder:

cd ~/amplifr
bundle exec data_integrity

It will load the Rails application, check the data integrity issues and give the similar output:

BelongsTo/ForeignKey: Label belongs_to project but has no foreign key to projects.id
Accordance/TablePresence: Stat::Hourly has no underlying table hourly_stats
...

Options

Check only specified database rules with --only options:

  bundle exec data_integrity --only HasMany/ForeignKey,BelongsTo/ForeignKey

Check only specified model with the list of the model full with:

  bundle exec data_integrity --only HasMany/ForeignKye Billing::Account User

Supported Issues

For now tool checks the following issues:

• The lack of database foreign keys for belongs_to/has_many associations (HasMany/ForeignKey and BelongsTo/ForeignKey rule)
• The lack of not-null constraint for the columns with presence validation (Validation/Presence rule)
• Inclusion validated colums should have enum data type (Validation/Inclusion rule)

Roadmap (TODO & Help Wanted)

1. Support extra database issues, such as:

• presence of dependend option set for association and not confliction with underlying ON DELETE option of foreign key contraint
• check for foreign keys to have bigint data type
• presence of index for the foreign keys search
• checks for paranoia models and indexes exclusion "removed" rows

2. Config for exluding some rules for the specific models (rubocop like)

3. Autofix for the fixing the issue, mostly by generating safe migrations

Run tests

The easiest way to tests up and running is to use handy dip gem with Docker and Docker Compose:

gem install dip
git checkout [email protected]:dsalahutdinov/activerecord-data_integrity.git
cd activerecord-data_integrity
dip provision
dip rspec

Otherwise (without Docker) set up environment manually:

git checkout [email protected]:dsalahutdinov/activerecord-data_integrity.git
cd activerecord-data_integrity
bundle install
bundle appraisal
DB_HOST=localhost DB_NAME=testdb DB_USERNAME=postgres bundle appraisal rspec
