Instance Method Details

#call(array, context:) ⇒ Array

Converts the array to JSON using the given serializers.

First, #call finds the best serializer from the :serializers Hash for each item in the Array. This is done by walking up the object class’s ancestors to find the closest ancestor which is a key in the :serializers Hash. The corresponding value is then called with the object, and the results are combined into a new Array and returned.

Parameters:

  • array (Array) —

    The array to convert to JSON.

  • context (Cuprum::Rails::Serializers::Context) —

    The serialization context, which includes the configured serializers for attributes or collection items.

Returns:

  • (Array) —

    a JSON-compatible representation of the array.

Raises:

  • UndefinedSerializerError if there is no matching serializer for any of the items in the array.
