SeedTracker 🌱
SeedTracker transforms your db/seeds.rb from a silent script into a clear, structured, and self-reporting process.
If you are tired of writing repetitive puts statements to figure out what your db/seeds.rb file actually did (what was created, updated, or left unchanged), SeedTracker provides a clean DSL and a beautiful summary output out-of-the-box.
Why SeedTracker?
Rails seeds are often:
- Silent
- Hard to debug
- Difficult to audit
- Unclear about what actually changed
SeedTracker solves this by turning your seeding process into a predictable and observable workflow.
Features
- 🚀 Lightweight: No runtime dependencies beyond Rails.
- 📊 Automated Summaries: Get a final report with counts of created, updated, and unchanged records per category.
- 🔍 Smart Diffing: It leverages ActiveRecord dirty tracking to detect exactly which attributes changed before saving.
- 💅 Visual Sections: Group your seed logs into readable, elegant blocks.
Compatibility
- Ruby >= 3.0
- Rails >= 6.0
Installation
Add this line to your application's Gemfile:
gem 'seed_tracker'
And then execute:
$ bundle install
Or install it yourself as:
$ gem install seed_tracker
Usage
Instead of relying on find_or_create_by! (which may silently create records without visibility into what changed), SeedTracker works best with find_or_initialize_by.
Here is how you can use it in your db/seeds.rb:
# 1. Initialize the tracker
tracker = SeedTracker::Base.new
puts "Running Seeds..."
# 2. Group your seeds using 'section'
tracker.section("PACKAGES") do
# 3. Use 'track' to process your records
# track(category_symbol, initialized_record, human_readable_label)
tracker.track(:packages, Package.find_or_initialize_by(category: :basic), 'Basic Package') do |p|
p.name = 'Basic'
p.price = 9.99
end
tracker.track(:packages, Package.find_or_initialize_by(category: :premium), 'Premium Package') do |p|
p.name = 'Premium'
p.price = 19.99
end
end
tracker.section("PLANS") do
# You can also assign the returned record to a variable to use it in associations
basic_package = Package.find_by(category: :basic)
tracker.track(:plans, Plan.find_or_initialize_by(period: :monthly, package: basic_package), 'Basic Monthly Plan') do |p|
p.name = 'Monthly'
p.active = true
end
end
# 4. Print the final summary dashboard at the end of the file
tracker.print_summary
