Hi, I've been trying to add default options by overriding the `to_json`
method of a model thinking it would get called when sent to `render :json`.
According to the documentation it should be working; from the guides:
You don’t need to call to_json on the object that you want to render. If you
use the :json option, render will automatically call to_json for you.
Unless that the behavior of render is different for collections. In that
case how can I do that?
In my controller I'm using:
def index; render json: Foo.all; end
And here the overrided method:
class Foo
...
def to_json(options = {})
super({methods: :rank}.merge options)
end
end
Calling to_json from the console work as expected. Also raising an exception
from the to_json method clearly demonstrate that the to_json isn't called by
render.
Thanks
