# ActiveModel::Serializer::Validator

This gem adds JSON schema validations for output generated by an `ActiveModel::Serializer`.

## Installation

Add this line to your application's Gemfile:

```ruby
gem 'active_model_serializers_validator'
```

## Usage

The gem adds one instance method and one class method to the `ActiveModel::Serializer` class, `#valid?` and `.json_schema`:

```ruby
class MySerializer < ActiveModel::Serializer
  json_schema '/path/to/my/schema.jsonschema'

  attribute :foo
end

serializer = MySerializer.new(OpenStruct.new(foo: 'bla'))

serializer.valid?
# => false

serializer.errors
# => [The property '#/foo' of type String did not match the following type: integer in schema /path/to/my/schema.jsonschema]
```
