tree_reject

tree_reject is a Ruby gem that removes deeply nested keys from Ruby Hashes or hash-like objects.

For example:

hash = {
  a: {
    aa: {
      aaa: 'aaa',
      aab: 'aab'
    }
  },
  b: {
    ba: 'ba'
  }
}

hash.tree_reject({
  a: {
    aa: :aaa
  }
})

results in:

{
  a: {
    aa: {
      aab: 'aab'
    }
  }, 
  b: {
    ba: 'ba'
  }
} 

Add this line to your application's Gemfile:

gem 'tree_reject'

And then execute:

$ bundle

Or install it yourself as:

$ gem install tree_reject

tree_reject extends Ruby's built-in Hash:

my_hash.tree_reject(ignored_keys)

It is also available for objects that support to_h.

TreeReject.tree_reject(my_hash_like, ignored_keys)
