Class Method Details

.call(opts, block = nil) ⇒ void

This method returns an undefined value.

Checks attribute :base_serializer option. It specifies the parent class for the nested serializer defined with the attribute block, so it makes sense only when a block is provided.

Parameters:

  • opts (Hash) —

    Attribute options

  • block (nil, Proc) (defaults to: nil) —

    Attribute block (defines a nested serializer)

Raises:

  • (SeregaError) —

    SeregaError that option has invalid value
