Troy,

Luiz needs to exclude a property from the returned JSON if — and only if — it’s value is null.

Cheers,

Flavio

Hey there,

You could use:

ERXKeyFilter filter = ERXKeyFilter.filterWithAttributes();

filter.exclude(Class.Nick, other keys);

return response(objectNSArray, filter);

Cheers!

Hi, I`ve been developing using WebObjects for 2 months and now i˜m working at a Rest API using ERRest framework.
I have a doubt about the possibility of not returning null values when a certain atribute of a class is null. For example, if an atribute is not filled, i`d like hiding it instead of returning null.

I`ve taken a look at the properties "nilKey" and "writeNilKey" of ERXRestFormatDelegate, but I`m not sure whether how to use them or how they can help me in my task.

This is how the API is leading with null values:
[
  {
    "id": 123,
    "typeClass": "Party",
    "fullName": "John Doe",
    "nick": null
  }
]
And here is how the return should be:
[
  {
    "id": 123,
    "typeClass": "Party",
    "fullName": "John Doe",
  }
]
Thank you, I`ll be waiting for your help.
