RejectDeeplyNested

Gem for rejecting deeply nested structures when you are using accept_nested_attributes_for. Using recursive traverse instead of stack because of this.

Add this line to your application's Gemfile:

gem 'reject_deeply_nested'

And then execute:

$ bundle

Or install it yourself as:

$ gem install reject_deeply_nested

There are two cases of using reject_deeply_nested

When you simply want to reject nested blank values:

accepts_nested_attributes_for :dependents,
  reject_if: RejectDeeplyNested.blank?

Other case, when you want to ignore some additional fields, for example id's keys

accepts_nested_attributes_for :dependents,
  reject_if: RejectDeeplyNested.blank?(ignore_values: [/_id$/])

Additionaly, if you want to reject not complete filled attributes you can use

accepts_nested_attributes_for :dependents,
  reject_if: RejectDeeplyNested.has_missed_fields?(['name', 'age'])

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
