Parse Json array and Json object in the same field

[Matej Briškár]

I am facing a problem when parsing expedia result. The result JSON differs according to the number of rooms available. In case multiple rooms are available, array is returned, otherwise only single object.

I am using case-classes for parsing the JSON, however I don't know what type to use to match both cases with the field (right now I am using something like List[Room], this fails in case one object is returned only).

Is there a way to catch this using case-classes only? If no, what other solution would you suggest?

Thanks,

Matej

Matej,

if you unmarshal to `Either[List[Room], Room]` things should “just work”.

Cheers,
Mathias

Once again: type-classes FTW!
