JSONValidate

This gem offers very simple way to validate parsed JSON object. Suppose your program expect an input JSON as below.

    {
      "id": 100,
      "title": "Some title",
      "tags": ["funny", "cute"]
    }

It can be validated by the following code.

    # assume json_str contains the JSON input
    object = JSON.parse(json_str)
    object.validate( {id: Fixnum, title: String, tags: [String]} )

If the JSON doesn't have designated structure, validate method raise a ValidationError.

    object = JSON.parse('{"hoge": 1}')
    object.validate( {id:Fixnum} ) # => raise ValidationError

Add this line to your application's Gemfile:

gem 'json_validate'

And then execute:

$ bundle

Or install it yourself as:

$ gem install json_validate
