Sprig::Reap

Don't want to write Sprig seed files from scratch? No problem! Sprig::Reap can create them for you. Sprig::Reap enables automatic capture and output of your application's data state to Sprig-formatted seed files.

Installation

# Command Line
gem install sprig-reap

# Gemfile
gem 'sprig-reap'

Usage

Via a rake task:

rake db:seed:reap

Or from the Rails console:

Sprig.reap

By default, Sprig::Reap will create seed files (currently in .yaml only) for every model in your Rails application. The seed files will be placed in a folder in db/seeds named after the current Rails.env.

If any of the models in your application are using STI, Sprig::Reap will create a single seed file named after the STI base model. STI sub-type records will all be written to that file.

Additional Configuration

Don't like the defaults when reaping Sprig::Reap records? Change 'em!

Target Environment

You may specify the target environment (db/seeds target folder):

# Rake Task
rake db:seed:reap TARGET_ENV=integration

# Rails Console
Sprig.reap(target_env: 'integration')

Model List

If you only want to reap a subset of your models, you may provide a list of models (ActiveRecord::Base.subclasses-only) or ActiveRecord::Relations (for pulling records based on scope):

# Rake Task
rake db:seed:reap MODELS=User,Post.published

# Rails Console
Sprig.reap(models: [User, Post.published])

Ignored Attributes

If there are any ignored attributes you don't want to show up in any of the seed files, let reap know:

# Rake Task
rake db:seed:reap IGNORED_ATTRS=created_at,updated_at

# Rails Console
Sprig.reap(ignored_attrs: [:created_at, :updated_at])

Omitting Empty Attributes

If you have models with lots of attributes that could potentially be nil/empty, the resulting seed files could get cluttered with all the nil values. Remove them from your seed files with:

# Rake Task
rake db:seed:reap OMIT_EMPTY_ATTRS=true

# Rails Console
Sprig.reap(omit_empty_attrs: true)

Combine Them All!

You're free to take or leave as many options as you'd like:

# Rake Task
rake db:seed:reap TARGET_ENV=integration MODELS=User,Post.published IGNORED_ATTRS=created_at,updated_at OMIT_EMPTY_ATTRS=true

# Rails Console
Sprig.reap(target_env: 'integration', models: [User, Post.published], ignored_attrs: [:created_at, :updated_at], omit_empty_attrs: true)

Adding to Existing Seed Files (.yaml only)

Already have some seed files set up? No worries! Sprig::Reap will detect existing seed files and append to them with the records from your database with no extra work needed. Sprig::Reap will automatically assign unique sprig_ids so you won't have to deal with pesky duplicates.

NOTE: Sprig::Reap does not account for your application or database validations. If you reap seed files from your database multiple times in a row without deleting the previous seed files or sprig records, you'll end up with duplicate sprig records (but they'll all have unique sprig_ids). This may cause validation issues when you seed your database.
