Error: undefined class/module

[sivicencio]

Hello. I've encountered with this when I've tried to cache an Active Resource model that includes an array as a field. The error is:

"undefined class/module Place::Child"

And the resource json response is:

[
    {
        "id" : 1,
        "name" : "Chile",
        "children": [
            {
                "id": 3,
                "name": "Metropolitana"
            },
            {
                "id": 4,
                "name": "Valparaíso"
            }
        ]
    },
    {
        "id" : 2,
        "name" : "Colombia",
        "children": [
            {
                "id": 5,
                "name": "Bogotá"
            },
            {
                "id": 6,
                "name": "Cartagena de Indias"
            }
        ]
    }
]

The "children" field is recognized as a class, not just as a simple field. Is there a way to avoid this?

Hi Sebastián, I don't have any immediate ideas, but I can take a look at it later. And just FYI, I am looking to move this project over to my github and update it to work with Rails 4 sometime in the near-ish future.

Great news! It's very useful if you're using Active Resource, so thank you for having the intention to make it work with Rails 4.

I've come with a solution: just added the next code inside my Place model (ApplicationResource is a class that inherits from ActiveResource::Base)

class Child < ApplicationResource
end

I'm going to go ahead and close this since it seems like a solution has been found.
