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
