JMSSerializer deserializing collection

Question

I have a problem with deserializing serialized collection of doctrine collections. Couldn't find docs about that and any topics and I'm new with JMSSerializer. When I try deserialize with:

$collection = $serializer->deserialize($jsonData,'Doctrine\Common\Collections\ArrayCollection','json');

$collection is empty

When I set to null instead of class name I have assoc array on result. Is there an elegant way to deserialize that json?

EDIT: Sorry. Here is serialized collection:

[{"id":88,"name":"Poland","created_at":"2012-09-28T11:59:06+0000"},{"id":90,"name":"Great Britain","created_at":"2012-09-28T11:59:06+0000"}]

can you paste the json of the serialized ArrayCollection to the question? – Almsman

Answer 1

Hah! Found what I done wrong :) I gave to deserialize method wrong type. Should be:

$serializer->deserialize($jsonData, 'ArrayCollection<EntityName>', 'json');

and it gave me beatiful array of entities.

Where did you find this solution? – Gilletta

by experiment only. No docs found unfortunately but looks like deserialize method can take as type argument same strings as defined for example here: types – Matsumoto

just what I was looking for. thanks for finding the solution! – Hydrargyrum

Sorry to bring alive an old question, however I was wondering if this is done inside the controller or the view? 2 years on and the docs are still somewhat lacking. – Yunyunfei

You saved me a lot of work this solution works perfectly thanks – Lode

I'm glad it is still helpful :) – Matsumoto
