Limpio

For some reason, you become some nasty nils in a response that you do not want to have?? you can get rid of them with this gem. It removes recursively the nils in Arrays and Hashes. The gems knows how to treat each kind of Object (String, true, false, etc) that in inside of the Hash/Array.

TIP: before using this gem, make sure why you are getting those ugly nils. Avoid them at all costs ;).

Installation

Add this line to your application's Gemfile:

gem 'limpio'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install limpio

Usage

The gem's API is really simple...it just contains one method.

For an Array:

array = [
  "value1",
  "",
  {
    key4: "value4",
    key5: "",
    key6: {
      key7: {}
    }
  },
  {},
  nil,
  [],
  [nil, 1.23],
  [nil, 123, false, true],
  true,
  false
]

result = array.deep_reject_blank!

p result
[
  "value1",
  {
    key4: "value4"
  },
  [1.23],
  [123, false, true],
  true,
  false
]

For an Hash:

hash = {
  key1: "value1",
  key2: "",
  key3: {
    key4: "value4",
    key5: "",
    key6: {
      key7: {}
    }
  },
  key8: {},
  key9: nil,
  key10: [],
  key11: [nil, 1.23],
  key12: [nil, 123, false, true],
  key13: true,
  key14: false
}

result = hash.deep_reject_blank!

p result
{
  key1: "value1",
  key3: {
    key4: "value4"
  },
  key11: [1.23],
  key12: [123, false, true],
  key13: true,
  key14: false
}
